Feb. 2024 climate extremes: Welcome to 2024 as we race down the road to Hothouse Earth

Incomplete Working Draft 25/02/2024 Usable as far as it goes!

2023 set new planetary extremes as our activities force global temperatures ever higher on the way to mass extinction. 2024 looks even worse! Soon humans will no longer be able to survive in the climate we are forging.

My featured image of the state of Earth’s oceans up to February 1 is already a bit dated (see below). The world’s sea surface temperature is still rising and setting new records every day since 14 March last year and is within 5 weeks of overlapping last years’ unbroken sequence of record days. ClimateReanalyzer – updated daily – shows global average Sea Surface Temperatures for every day since Sept 1, 1981. (This web page also provides links to details on the methodologies used to compute these values.)

The implications of these observations is truly alarming when placed in the context of Earth’s climate system. Emergency mobilization of global action is required if we are to have any hope of avoiding the existential consequences of runaway warming that may have actually started. This level of action will require many individual sacrifices that governments and people will be reluctant to make. However, history shows (e.g., mobilization for WWII)1 that humans can and will unite and act if the reality of the threat is accepted and taken seriously.

What follows is no hoax! It is how universal physical laws work in the real world of our planet. Ignore the evidence at your peril, or accept reality and work to survive the impending apocalypse foretold. As will be explained, my featured image announces the existential threat all humanity faces from global warming – currently being largely ignored by politicians, press, and citizens.

March 15, 2024, when this year’s continuous all-time record heating builds on top of last year’s continuous-all time record heating, should be taken as our “Pearl Harbor Day“.

Hot oceans drive many potentially catastrophic changes to planetary climate.

Earth’s accelerating energy imbalance

Earth oceans are warming at a geologically prodigious rate that we can clearly see major changes in a human lifetime (Figure 1). This is because oceans are being flooded with excess energy much faster than they can lose it. The rising temperature has dire consequences. However, before presenting the consequences of ocean warming, we should understand what is causing the warming.

The average surface temperature of our planet (i.e., the biosphere) is determined by balance between the amount of (heat) energy it receives from all sources versus the amount of energy it loses to outer space as radiant heat.

The vast amount of energy received by the biosphere comes directly from the Sun, as “radiant energy“, mainly in the form of visible light. This varies only slightly over time, due to astronomical factors. There are also two very minor internal sources (“internal energy“) left over from Earth’s formation billions of years ago that I mention for completeness: (1) the decay of radioactive elements in the Earth’s body and (2) the residue heat from the conversion of gravitational potential energy into heat as our planet formed by condensation of small part of the solar nebula that also gave birth to the Sun. This internal energy, brought to the surface from below by conduction and volcanic activity, accounts for only about 0.03% of the total energy warming the surface.

Given that vacuums cannot conduct heat, and that gravity stops particles from carrying away energy (i.e., convection), the only way Earth can lose heat is by radiation. All objects warmer than absolute zero, including Earth, lose heat by “black-body” radiation. Objects close to absolute zero lose energy via microwave radiation. As the object’s temperature rises heat energy is able to escape at shorter (more energetic) wavelengths – with a growing percentage of energy at these shorter wavelengths. E.g., hot iron may be ‘red hot’; molten iron is literally ‘white hot’. The hottest stars actually radiate most of their energy at the blue end of the spectrum. Under normal circumstances surface temperature fluctuates up and down until there is a balance between the amount of radiant energy received by the surface and the amount energy radiated away.

At Planet Earth’s temperature, most heat is lost as relatively short wavelength infrared radiation, because ‘greenhouse gases‘ block some of the longer wavelengths (Wikipedia’s articles do a good job of explaining the physical laws and processes governing Earth’s energy budget). With no greenhouse gases in the atmosphere, the average temperature of Earth’s surface would be about −18 °C, rather than the present average around 15 °C. As explained, for a given mix and concentration of greenhouse gases Earth’s average temperature will rise or fall until the same amount of energy (mainly in the form of infrared) is radiated to outer space as is received from the Sun (mainly in the form of visible light).

However, Figure 2 shows that is not the case today. Our planet is suffering from what is an extraordinarily rapidly growing energy imbalance that vastly exceeds anything that can be reconstructed from the last 150,000 year geological record of the planet. Currently, 93% of the excess energy is being stored by heating the Ocean. According to Trenberth and Cheng (2022),

About 93% of the extra heat from [Earth’s Energy Imbalance] ends up in the ocean as increasing ocean heat content (OHC). In 2022, the global OHC was the highest on record (Cheng et al 2022) and the global warming signal in OHC is large compared with the natural variability, unlike [Global Mean Surface Temperature], so that trends in OHC can be detected in four years….]

Physics Today. for a short take on how these measurements were made. @Leon Simons’ X-Twitter thread presents what he calls “The most important graph in the world”, and explains the methodology in more detail.

Figure 3 below, shows that this imbalance is rapidly growing in the 21st Century, the latest reading (mid 2023) is around 5 times what it was in 2001. This imbalance is what is driving the rapid growth of sea-surface temperatures shown in Figure 1.

Figure 3. Growth in Earths Energy Imbalance. @Leon Simons

The only thing that will forestall that flood of excess energy into the oceans making them even hotter is to reverse the imbalance by radically reducing the concentration of greenhouse gases in the atmosphere allowing more heat to escape AND by reflecting more of the incident energy back to space before it is absorbed into the oceans.

Regarding reflection, Leon Simmons2 and others have shown that a reflective smog of sulfate aerosols produced by worldwide shipping burning dirty, sulfur-rich diesel fuel slowed ocean warming by a significant amount. This source of sulfur emissions largely stopped when the International Maritime Organization shipping regulations increasingly restricted sulfate emissions (see Hansen, Sato, Simons et al., 2023. Global warming in the pipeline. Oxford Open Climate Change). This unplanned experiment and the Mt Pinatubo eruption in 1991 demonstrated that sulfate aerosols could measurably reduce the amount of solar heat absorbed by Earth. However, given that the aerosol particles basically consist of concentrated sulfuric acid that eventually falls into the living biosphere to acidify land and ocean, sulfate aerosol production will probably cause more problems than the additional heating allowed by clean air. IPCC climate modeling grossly under represents the energy imbalance (Schmidt et al., 2023. CERESMIP: a climate modeling protocol to investigate recent trends in the Earth’s Energy Imbalance. Frontiers in climate; see also Leon Simons X-Twitter thread).

Ocean currents distribute excess heat from hottest areas to the rest of the planet. Far more heat energy enters the air via convection and increased humidity carrying latent heat in vaporized water from the oceans than is absorbed directly from Solar radiation. Heated land also contributes energy to the atmosphere via evaporation and convection.

Figure 6. On 18 February, the air temperature in Perth, Western Australia was so far beyond the kinds of record highs that can be expected from random variation around some “normal’ value for the time of the year that it was unimaginable — until it was recorded.

And then it was much hotter than Perth further up the Western Australian coast! See Sophie McNeil – https://twitter.com/Sophiemcneill/status/1759174092597715078: 10 °C hotter in Canarvon and Shark Bay Airport; and based on satellite measurements, probably at least 14 °C hotter on the flatland inland of Shark Bay where there are no ground-based weather stations to record the measure. Closer to the boiling point of water than the freezing point! and well above temperatures where unprotected humans could survive. WeatherZone Business highlights these observations on their Instagram account.

WeatherZone’s map, with Australian Bureau of Meteorology data Carnarvon Airport and Shark Bay Airport for 10 days as an inset. Given that the BOM’s reported dates for the official data apply to the preceding 24 hours, the actual peak temperatures would have occurred around 1 PM on the 17th of February.

This heating of the oceans (Figure 1) and atmosphere (Figures 4 and 5) caused by the energy imbalance is already causing a range of catastrophic extreme weather events around the world. However, before exploring these further we should first consider what causes the energy imbalance.

Global warming is caused by increasing concentrations of greenhouse gases emitted by and as a consequence of human activities.

Until the accelerating trends illustrated in the following graphs can be reversed to the point that the “increase” graphs extend into negative territory and the “concentration” curves begin to curve downward to show decreasing concentrations, physical laws determine that forcing of the energy imbalance (Figure 3) will continue to grow ever more lethal for the biosphere. The main forcing factor is the still accelerating rising concentration of infra-red blocking greenhouse gases.

Figure 6. Continuously growing concentrations of major greenhouse gas as a 10 February 2023 are amplified by increasing rates of growth. See https://gml.noaa.gov/ccgg/trends/.

The record for direct CO2 measurements, a carbon dioxide concentration of 426.5 parts per million (ppm), was observed on Friday Feb. 3 2024 when the wind over Mauna Loa shifted to more northerly. This brought air in from North American and East Asian industrial areas thousands of miles upwind.

Figure 7. The Keeling Curve is a daily record of global atmospheric carbon dioxide concentration maintained by Scripps Institution of Oceanography at UC San Diego – https://keelingcurve.ucsd.edu/. Note:  “On Saturday, Feb. 3, the daily Keeling Curve record was broken when instruments at Mauna Loa detected a carbon dioxide concentration of 426.5 parts per million (ppm). It was the first time in the modern record a daily reading had exceeded 425 ppm, though the annual peak does not typically take place until May. Since then, several daily readings have surpassed 425 ppm. The reading was also an increase of more than 4 ppm from the previous day’s. Scripps CO2 Program Director Ralph Keeling said that a shift in weather patterns played a role. “We attribute the large increase in CO2 that occurred from Feb. 2 to Feb. 3 to a strong wind shift, as a new weather system moved in,” Keeling said.  “Before this weather shift, the Mauna Loa Observatory was receiving air that had blown in from lower latitudes.  After the shift, the air was coming from northern latitudes, where CO2 is normally higher this time of year.  An upwards shift in CO2 was therefore to be expected.”- https://keelingcurve.ucsd.edu/2024/02/10/on-this-weeks-record-high-co2-readings-at-mauna-loa/.

These measurements are made in many locations around the world as indicated on the following world map.

Figure 8. Locations where greenhouse gases are measured on a regular basis to track changes through time. Solid symbols are currently active measurement programs. Open symbols designate locations used in the past. – https://gml.noaa.gov/ccgg/about.html

Wherever in the world these trends are measured the increasing concentrations of principal greenhouse gases show similar patterns. For example:

Figure 9. Recent growth in CO2 from pole to pole – https://gml.noaa.gov/ccgg/trends/gl_trend.html
The figure shows daily averaged CO2 from four GML Atmospheric Baseline observatories; Barrow, Alaska (in blue), Mauna Loa, Hawaii (in red), American Samoa (in green), and South Pole, Antarctica (in yellow). The thick black lines represent the average of the smoothed seasonal curves and the smoothed, de-seasonalized curves for each of the records. These lines are a very good estimate of the global average levels of CO2. Details about how the smoothed seasonal cycle and trend are calculated from the daily data are available here.

The four locations in this chart show relative decreases going from north to south. A majority of emissions are made in the Northern Hemisphere and a majority of the draw-down into the biosphere occurs in the oceans of the Southern Hemisphere.

The way in which this excess heat is distributed around our planet has profound implications for the planetary biosphere and human survival in it as expressed in the inevitable weather and climate extremes as the world warms beyond our physiological limits of adaptation.

Ocean circulation is the major engine distributing excess heat around the planet.

We know a great deal about the dynamics of ocean heating and the distribution of heat through the international Argo Float program (see Fig. 11 for a link describing the Argo program).

Figure 11. The global distribution of active floats in the Argo array. The program started around 2001. In Jan 2024 there were 3879 floats. Although the USA operated the majority, 23 other nations also provided and operated floats, making it a truly international endeavor. – https://argo.ucsd.edu/about/ explains what the floats can do and how the data they produce is processed.

Wikipedia’s Ocean Heat Content article explains how the ocean redistributes its heat content around the planet.

Figure 12. Ocean heat content (OHC) is the energy absorbed and stored by oceans. To calculate the ocean heat content, it is necessary to measure ocean temperature at many different locations and depths. Vast amounts are stored in the ocean depths that may continue driving extreme events for several to many years even if we achieve surface cooling.

Heat absorbed in the ocean is circulated around the planet by ocean currents, where much of it is transferred over time to the atmosphere by direct contact.

Figure 13. Rising global average temperatures (as measured in the air 2 m above the ground). Note: 1940 is the oldest year shown on this chart.

AMOC under threat

Earth’s ocean currents are critical in distributing and regulating heat over the entire planet. These currents are largely driven by temperature differences between polar and tropical waters. Although it is smaller the Atlantic Ocean’s circulation is probably the most important because it is the primary connection between the Arctic Ocean and the tropical regions. (The shallow Bering Strait between NE Asia and Alaska completely blocks the exchange of deep waters). Wikipedia explains in detail:

The Atlantic meridional overturning circulation (AMOC) is a system of surface-level and deep currents in the Atlantic Ocean which are driven both by changes in the atmospheric weather and thermohaline changes in temperature and salinity. These currents collectively make up one half of the global thermohaline circulation that encompasses the flow of major ocean currents. The other half is the Southern Ocean overturning circulation, and both play highly important roles in the climate system.

Also, the most extreme oceanic heating has taken place in the North Atlantic (where shipping traffic has been the most concentrated and where there has been the greatest reduction in sulfate emissions).

Hot water in the North Atlantic does two things:

  1. It warms the surface waters in the Arctic.
  2. Excess heat in the ocean and in the air heated by the ocean speeds the melting of glaciers to dilute the salinity of the ocean at their feet (and raise sea levels).

Both factors work together to reduce the density of the northern waters to the point that they are no longer able to sink below relatively dense mid-level waters to form the Atlantic Deep Water flowing back to the tropics, leaving the warm currents (e.g., the Gulf Stream) bringing heat up from the south no place to go, stopping the flow. Paradoxically will probably allow NE North America and NW Europe.

Leon Simons’ thread below explains:

Figure 14. Follow Leon Simons’ Show more thread for a detailed summary of how these conclusions were reached, and discussion of consequences.

Marine dieoffs and the collapse of marine ecosystems

Also, as the oceans rapidly grow hotter, we’ll soon see the extinction of keystone coral species and collapses of ecosystems they support. Not only will we lose many species but their rotting remains will emit greenhouse gases such as CO2 and poisonous hydrogen sulfide gas…. The additional CO2 emissions will add to positive feedback increasing the energy imbalance and global heating.

In Australia and elsewhere, other than coral bleaching and death (e.g., the Guardian’s latest – Bleaching fears along 1,000km stretch of the Great Barrier Reef), we are also seeing dieoffs of mangrove, sea grass, and kelp. For several years we have known these were happening, but as the ocean continues to warm, the die-offs will take place faster and more comprehensively until the species (and the ecosystems they support) are lost entirely (i.e., become extinct).

Ice melting and sea-level rises

Warm oceans carry prodigious amounts of heat into polar zones, to substantially increase the rate of ice melting and raising polar temperatures to slow and eventually stop re-freezing. There is ample evidence for a greatly increased rate of melting.

Figure 15.

Antarctic sea ice extent is currently very close to its all-time low recorded last year. There is no indication yet that this year it won’t breach that record. In any case, at only 2 million Km2 the Antarctic Ocean will not be reflecting much heat away from the planet.

Figure 16

Warming produces melt-water that lubricates ice into a hot ocean

Figure 17. Dawson et al., 19 Jan. 2024. Heterogeneous Basal Thermal Conditions Underpinning the Adélie-George V Coast, East Antarctica. Geophysical Research Letters.
East Antarctica’s Adélie-George V Land has been relatively stable over the last few decades. However, this region contains the Wilkes Subglacial Basin, which has a downward-sloping bed inland of the grounding zone. This could make irreversible retreat possible if warming seawater off the coast enters beneath the ice sheet…. We find that areas near the outflow of the Wilkes Subglacial Basin, critical in maintaining the stability of the region, might consist of mixed frozen-bed and thawed-bed or near-thawed conditions on the scale of tens of kilometers across. This finding is important since the extent of basal thaw affects how easily ice can flow or slide over the bed. If parts of the bed are close to thawed, this could make Adélie-George V Land more sensitive to climate forcing, possibly resulting in mass loss. For media articles see also: https://news.stanford.edu/2024/02/05/stable-parts-east-antarctica-ice-may-close-melting/; California-size Antarctic ice sheet once thought stable may actually be at tipping point for collapse.

Where Antarctica is concerned, its land ice has the potential to cause major rises in global sea levels compared to what Greenland can do. In 2024, East and West Antarctica’s riskiest glaciers are still plugged by grounded ice. However, as the article referenced above (Figure 17) discusses, several of the plugs on the largest glaciers are showing signs of impending collapse.

Sea levels are rising at an accelerating rate as a consequence of melting land ice (mainly Greenland and Antarctica)

Figure . Mean Sea Level. (https://www.aviso.altimetry.fr/en/data/products/ocean-indicators-products/mean-sea-level.html)
As global warming occurs, a direct reaction of the climate system is the sea level rise. This rise results from seawater expansion as a response to the temperature increase and addition of water from land-ice sheets and glaciers melting. Precise monitoring of the sea level rise is made possible using altimetry satellites that help understanding climate change and its socioeconomic consequences. The Global Mean Sea Level (GMSL) has thus become a key indicator of climate change.
The reference global mean sea level (GMSL) based on data from the TopEx/Poseidon, Jason-1, Jason-2, Jason-3 and Sentinel-6MF missions from January 1993 to present, after removing the annual and semi-annual signals and applying a 6-month filter. By applying the postglacial rebound correction (-0.3 mm/yr), the rise in mean sea level has thus been estimated to 3.6 mm/year with an uncertainty of 0.3 mm/yr.
Note that over the last quarter of year 2022, Sentinel-6 MF is affected by an inaccurate radiometer calibration error resulting in an overestimation of the wet tropospheric correction and therefore of the GMSL by about 5 mm (see issue #9170 of EUMETSAT User Notification Service at https://uns.eumetsat.int/ ).
Analyzing the uncertainty of the altimetry observing system yields to construct an uncertainty envelop for the GMSL climate data record (shaded area in the figure above). 
The dashed line displayed over 1993-1998 is an estimation of the GMSL evolution after correction of the TOPEX-A instrumental drift (Cazenave WCRP 2018). It is estimated from empirical correction derived by comparing altimetry and tide-gauge sea level data (see more details in Validation). The TOPEX-A instrumental drift led to overestimate the GMSL slope during the first 6 years of the altimetry record. Accounting for this correction changes the shape of the GMSL curve, that is no more linear but quadratic, indicating that the mean sea level is accelerating during the altimetry era (1993-to present, Beckley et al. 2017, Nerem et al. 2018). Currently, this empirical correction is not applied to the AVISO GMSL dataset, wainting for the ongoing TOPEX reprocessing by CNES and NASA/JPL.

The most immediate dangers from ice melting are in the Arctic Ocean

Greenland’s contribution to sea level rise, is limited by its small size compared to Antarctica. However, the Arctic Ocean’s potential to reflect significant percentage of solar energy over many days of 24 hour summer sunlight plays is an important component in Earths energy balance.

Summer minimums of Arctic sea ice extents from 1980 to 2023. (https://seaice.visuals.earth/)
Figure 18. Albedo sea ice surface types and associated feedbacks in Earths energy imbalance.
The albedo for different surface conditions on the sea ice range widely, from roughly 85 per cent of radiation reflected for snow-covered ice to 7 per cent for open water. These two surfaces cover the range from the largest to the smallest albedo on earth. Melting snow, bare ice and ponded ice lie within this range. There is a general decrease in the albedo of the ice cover during the melt season as the snow-covered ice is replaced by a mix of melting snow, bare ice, and ponded ice. As the melt season progresses, the bare ice albedo remains fairly stable, but the pond albedo decreases. During summer the ice cover retreats, exposing more of the ocean, and the albedo of the remaining ice decreases as the snow cover melts and melt ponds form and evolve. These processes combine to form the ice–albedo feedback mechanism.

With some fluctuations, for the last several decades the extent of Arctic sea ice has been declining to annual minimums in the 2020s to around half the area the ice covered in the early 1980s. With much less apparent impact to now, the thickness of winter ice has also been diminishing significantly, to the point that within a very the extent of midsummer ice will show a catastrophic drop to virtually nothing as its thickness drops to zero, as several national technologies have shown in the following thickness maps.

Figure 19. Charctic image from the US National Snow and Ice Data Center, Sea Ice News. Near the midwinter peak of Arctic freezing (16.02.2024) 10% open water extends up from the North Atlantic near to and past the North Pole! For ‘extent’ an area is considered to be ice more than 15 percent of the surface is covered by ice.
Figure 20. Estimated Arctic sea ice thickness for 16 Feb. 2024. US Naval Research Laboratory HYCOM Consortium for Data-Assimilative Ocean Modeling – GOFS 3.1
Real-time 1/12° Global HYCOM+CICE Nowcast/Forecast System. Close to the winter maximum extent, except for a tiny sliver of thicker ice piled up close on the northernmost areas of the Canadian Archipelago and Greenland. The thickest sea ice anywhere on the Arctic ocean is < 2.6 m. Over half the coverage is < 1.5 m. In the early 1980’s large areas of the Ocean north of Canada and Alaska were covered by 4 to even 5 m thick ice.

Given geopolitical conditions around the margins of the Arctic Ocean, the US Navy is particularly concerned with ice conditions in relationship submarine and surface ship navigation. The CICE Nowcast system developed by the US Navy Research Labs, was only operational beginning in 2015, but even beginning from then, a year before the minimum ice extent yet was recorded in 2016, today’s ice thickness is conspicuously less than ~ a decade ago.

Figure 21. Sea ice thickness for Feb 19 for 2015 and 2024 compared. (Source details as per Fig 20.). In 2015 there is still a significant area of ice greater than 3.5 m thick. In 2024 this is reduced to a practically invisible sliver against the Canadian Archipelago and Greenland.

The next series of graphics are from European sources – mainly from the Danish Meteorological Institute’s Polar Portal. Greenland and the Faeroe Islands are autonomous territories of Denmark, so their waters are territorial waters of Denmark – which accounts for their longtime concern with navigability and sea ice conditions in the Arctic and North Atlantic.

Figure 22. Sea ice thickness for Feb 1 for 2004 and 2024 compared. !n 2004 there were still extensive areas of the ocean covered by 4 m thick ice, and in 2024 thicker areas of ice were greatly reduced, but not quite to the extreme indicated on the US CICE maps (Fig 21).. As at 21 Feb, 2024 sea ice thickness is at a record low for this date in the series.

Some of the clearest and most intelligible data outputs of sea-ice changes are produced by University of Bremen’s research group on “Remote Sensing of Polar Regions“. Several of their programs connect directly with the EU’s Copernicus programs in climate science. Compare the observations below with US and Danish systems.

Figure 23. AMSR2 sea ice concentration. Monitoring of changes on a daily basis. The image here for 20 Feb 2024, (MODIS-AMSR2, 1 km). Since October 2019, we have been producing sea-ice concentration at 1 km grid resolution retrieved jointly from MODIS and ASI-AMSR2 data. The data are available operationally between October 1st and May 31st. No retrieval is performed in Summer. The color pallet used clearly identifies the different sea ice concentration values. Here you can very clearly see how much open water there is within the extent bounds of the ice cap. E.g., in the northern midwinter, the red areas indicate where there is between 10 and 15 % open water.extending from the extremities of the North Atlantic more than halfway across the ice cap passing in close proximity to the North Pole.
Figure 23. Left. Concentration of multi-year ice on 4 Feb 2024. This is a product of the Multiyear Ice Concentration and Ice Type project. Clearly most of the Arctic sea ice is less than a year old!. Some of new ice formed this year could get squashed together to make thicker multi-year. But it is likely that most will melt over summer to make a ‘blue’ ocean. Right. Product of the Thin Ice Thickness project. Analytical tools have been developed to estimate the thickness of thin skins of ice down to centimeter accuracy. This map from 20 Feb 2024 shows clearly that a large continuous expanse of the Arctic Ocean close to the North Pole is covered by only a very thin skin of ice less than 10 cm thick (which would account for the fact that it is easily broken up enough to expose patches of open ocean indicated by the concentration maps.

The conclusion to be drawn from the body of remote sensing observations (backed up by oceanographic cruises such as the Polarstern‘s voyages) is that the ice sheet, still covering most the Arctic Ocean in the summer, is presently teetering on the brink of collapse, possibly as early as this year or the next. Replacing the almost totally reflective ice with close to totally absorptive blue ocean as shown in Figure 18 will substantially increase Earth’s energy imbalance. Depending on how fast 24 hour solar heating warms the surface waters above the freezing point, the Arctic Ocean may soon remain ice-free over winter as well…..

One more set of ice observations seems to support the perilous state of Earth’s cryosphere.

Figure 24

Cartoonists sometimes have the knack of expressing human foibles. Their few words about cliimate hoaxes may provide a bit of a break before the last bit of climate reality reality that we humans are the only thing left with the capacity to resolve

Figure 25 a couple of cartoons illustrating some of the difficulties in accepting physical reality. My guess is that pictures on the left are from last year’s movie, “Don’t Look Up” – only here we are talking of a few decades or years – where immediate action might actually minimize the collapse, while in the movie it was a matter of days….

The universal laws of nature and evolution are what they are irrespective of human desires and intents

Most of these laws relate to the interactions of heat energy and pressure on gases, their mutual solubilities and changes of state from gas ⇌ liquid ⇌ solid, and their spectroscopic properties (i.e., measurable details of how they absorb and emit different wavelengths of radiant energy as a function of temperature and pressures. These differ considerably among the important gases that generate weather (water, CO2, methane). These three gases also are heavily involved in very different ways in various aspects of the metabolisms of living systems. Physical interactions of the gases were already well understood in the early 20th Century and the biological behaviors by the 1960s and 1970s. What they do in all possible circumstances is purely a function of the fundamental laws of physics and chemistry that are totally independent of any human beliefs, fears, and desires. In other words, we have to live (or die) with what the Universe provides us.

This includes extreme weather that is mostly driven by energy released or consumed by water as it changes in temperature (the energy here is called ‘sensible heat‘ because we can actually feel the temperature changing) or changes its state from solid ice, to liquid, to gas (water vapor). The changes between ice and liquid water, and liquid water and water vapor consume large amounts of energy, but do not change the temperature. In this case the energy being transferred is called ‘latent energy‘.

Either kind of energy will change the density/pressure of the liquid or gas transferring the energy, or conversely externally pressure changes will affect the energy content of the parcel of molecules being affected by the pressure. Wikipedia’s article on ‘Weather’ explains how these laws work to generate weather. The basic message I am trying to communicate here is that the more energy applied to parcel of atmosphere, the more extreme its weather will be….

Figure 26. Simple laws have major consequences! A useful rule of thumb is that the maximum absolute humidity doubles for every 11 °C increase in temperature. Thus, the relative humidity will drop by a factor of 2 for each 11 °C increase in temperature, assuming conservation of absolute moisture. For example, in the range of normal temperatures, air at 20 °C and 50% relative humidity will become saturated if cooled to 10 °C, its dew point, and 5 °C air at 80% relative humidity warmed to 20 °C will have a relative humidity of only 29% and feel dry (and have much more capacity to induce drought by drawing water out of crops and agricultural soils.

Extreme weather driven by heat and humidity by anthropogenic greenhouse gas emissions

(1) Canada has a large proportion of the world’s subarctic/Boreal forests including a large area on carbon rich peaty soils on permafrost. For 20 years Canada has had a powerful satellite system for objectively tracking thee extent of wildfires. Record high temperatures and drought led to burning over 4x more area than previous years. Some of the fires are still burning today in the peat soils and are already beginning to surface for the 2024 fire season (see also). (2) on Sept. 10-11, 2023, a few days after dumping more than a meter of water on the north-eastern agricultural area of Greece, Storm Daniel dumped enough water on the Cyrenaican area of Libya to erase a major part of the high-rise center of the city of Derna, along with around 13,000 of the city’s inhabitants (see Derna is our 9/11 for climate action for my initial survey of the event).. I am still documenting details of the flooding from the comprehensive satellite, press, and social media imagery available, but it is clear from dateable geological evidence that this is the most extreme flood event along this area of coast since the Eemian period of the Last Interglacial ~120,000 years ago. (3) Mexico’s major Pacific Coast resort city of Acapulco was comprehensively smashed by Cat 5 hurricane Otis. According to the US National Hurricane Center, Otis was the strongest hurricane in the Eastern Pacific to make landfall in the satellite era, and the second most rapidly intensifying hurricane in the recent era (US NOAA – National Environmental Satellite, Data, and Information Service; unbelievable videos). (4) Chile’s heatwaves and firestorms in early February are unprecedented and have killed more than 100 people.

The observations point to the conclusion that we have already entered a new climate regime of positive feedbacks that are forcing Earth’s Climate System into the Hothouse Earth mode at least comparable to what caused the End Permian global mass extinction event – only over a much shorter time scale.

We must change the politics that has allowed this to happen and will prevent effective action that may for a small while yet allow humanity to climb back up over the cliff before we are cooked in the caldera of the hothouse

  1. America’s mobilization for WWII shows what humans can do in an emergency situation if they work together.
    I was born in 1939 and am old enough to actually remember the war’s ending: My father worked in the defence industry. We lived on a boat in the Port of Los Angeles close to the 2nd largest builder of Liberty Ships in the USA, and then in San Diego Harbor directly opposite North Island Naval Air Station and home port of the Pacific Fleet’s aircraft carriers. In my postgraduate career I worked for 15 months for the Atomic Energy Corporation; and for the last 17½ years prior to retirement I was a knowledge management systems analyst and designer in logistics support engineering for Tenix Defence (at the time, Australia’s largest defence engineering project manager). I have also read a lot of history, so I know a bit about what was mobilized and how it was done.
    Until Dec 7 1941 when Japan bombed Pearl Harbor, Americans were isolationist deniers of the reality of Axis aggression (not unlike Trumpist ‘MAGA’). By 8 May 1945 Germany had been expunged and on 6 Aug. 1945 the atomic bombing of Hiroshima (and then Nagasaki a few days later) overwhelmed Japan. In 1941 nuclear fission was a wacky idea proposed by some academics. In 4 years nuclear science was developed, the Manhattan Project was conceived, several different kinds of production infrastructure (Hanford, Oak Ridge Facility, Savanna River)(a bit after the War), Los Alamos, etc…) were designed and built, atom bombs were designed, built, tested, and used. In the area of engineering and logistics, an average of 5 highly capable destroyers were built each month for 32 months and an average of 3 Liberty Ships every 2 days between 1941 and 1945. were able to be assembled and launched each week. The United Nations was formed, etc.. Equally prodigious challenges were met in many other areas that completely changed world history. Yes, conscription, coercion, rationing, etc. was required – but the global challenge was met and the common danger vanquished….
    Today, we have massively more knowledge and prowess than we did in the early 1940’s. Humans can do remarkable things if people and governments unite and work together to fight the common danger. There is no greater danger than the near term extinction of our entire species and most of the rest of Earth’s biosphere! ↩︎
  2. Leon Simons makes a good case that the abrupt rise in the imbalance is at least partially due to the sharp reduction of sulfur emissions from worldwide shipping. The smog emitted along with CO2 by the burning of especially sulfurous diesel bunker fuel in the voyages of hundreds of thousands of ships per year almost certainly reflected a portion of the incoming solar energy back to space before it had a chance to be absorbed into the ocean – especially in the highly trafficked North Atlantic. See https://twitter.com/LeonSimons8/status/1668612887949217792. Stopping the sulfur emissions would certainly allow more solar energy to impinge on the ocean. Nevertheless it is still likely that the bulk of the rising temperature is due to the the increase in absorbed energy caused by the also rapidly increasing concentrations of greenhouse gases. ↩︎

What if this year’s records extend last year’s? 2 months to go…

On Saturday the Sea Surface Temperature (SST) was less than 0.1 °C below last year’s record set in August. Traditionally the global peak temperature for the year is reached in March. This year will probably be well and truly off this chart, yet humans are still burning fossil fuels at an increasing rate driving us ever faster towards global mass extinction in runaway warming as polar permafrosts and retreating ice-sheets release vast stores of soil carbon as methane and CO2.

Note that about 90% of the excess solar energy absorbed by our planet goes into the upper layers of the oceans before being redistributed via increased atmospheric humidity and heat to fuel increasingly extreme and lethal climates and weather events.

The only hope our species has to stop this apocalypse is to reverse greenhouse emissions (stop new emissions and ‘draw down’ and sequester some of the existing excess) and reflect more solar energy away from Planet Earth.

Isn’t it time we made our governments work towards this rather than increasing the obscene profits of their mates and patrons in the fossil fuel industries?

If you want more evidence in favor of this choice, please read my past posts on Climate Sentinel News. As well as using your vote effectively, Vote Climate One suggests a number of things you can do between elections to pressurize your governments to work with you (rather than against) to solve the climate emergency.

ICUMI: global temps > 1.5 °C pre-industrial baseline SINCE 6 Sept

The Copernicus report said if December records a similar temperature anomaly to November, the average temperature for 2023 will be 1.48 degrees above the pre-industrial reference level.”

Chances are that if December is significantly hotter than November, Earth will break the 1.5 °C ‘barrier’ this year, that COP 28 is supposedly working towards stopping…… See the featured image here from the ABC article (“Global temperatures in 2023 are tracking well above every other year on record. / Supplied: ERA5/C3S/ECMWF)”

ABC gives the facts below. Climate Sentinel News has spent many months reporting how continued warming will result in near term human extinction (i.e., possibly within the currently expected lifetimes of humans living today). We suggest that you review these warnings and take them very seriously indeed, and work collectively to force our governments to immediately force the fossil fuel industry to stop carbon emissions of all kinds.

Yes, we will probably need to implement energy rationing while sustainable resources are ramped up. However, this is better than allowing Fossil Fuel control our governments and condemn Earth life to global mass extinction.

Scientists have confirmed 2023 is the hottest year on record, with a month to spare

Jess Davis, 8/12/2023 in ABC NEWS

Scientists have confirmed 2023 will be the hottest year on record, with the official declaration from climate change service Copernicus, run by the EU, made with a month to spare.

The startling heat records come as large parts of Australia are set to endure heatwave conditions, with temperatures expected to reach over 40 degrees in some places.

The world can’t stop breaking heat records this year, with each month since June becoming the warmest on record.

The Copernicus data confirmed the trend, with the warmest November on record globally hitting 1.75 degrees above the 1850–1900 pre-industrial reference period….

Editor’s comment

I haven’t posted a lot in the last couple of months.

September was horrific for its climate catastrophes and broken records for climate extremes at the end of the Northern Hemisphere’s summer. For example:

Even worse for me personally, has been the fact that people in general paid virtually no attention to or showed any understanding of the significance of these and many other comparably extreme climate events and situations requiring emergency action.

Also, more specifically, the Derna situation was so extreme that I could not understand how a single overnight flash flood could comprehensively erase the fundamental infrastructure and fabric of a modern city — even given the fact that two earth-fill embankment dams were also almost completely erased in the process. Most people have blamed the cataclysm on the failed dams, making it easy to gloss over the fact that the dams were casualties not causes. Thus, I have felt compelled to spend my time forensically studying the vast array of imagery of the Cyrenaican region of Libya where Derna is located before, during, and after the flood(at resolutions down to 25-50 cm), press photography, drones, and ‘witness’ reports on social media to determine what actually happened.

Briefly summarizing what I have determined so far:

Derna was built on a relatively flat fossil delta whose seaward edge is 7-8 m above sea level, such that all runoff falls over sea-cliffs to reach the Mediterranean sea. The imagery of damage to surviving buildings more than 200 m from the banks of the normally dry wadi running through the city convincingly shows major flood damage up to the 3rd or even 4th floors. On the evening of Sept. 10 when the rain started the wadi reached the ocean via a 6 m drop at the delta’s edge. On Sept. 11 as the flash flooding was receding, the now uniformly sloping wadi floor reached sea level ~ 450 meters inland from where its spout had been the night before.

Making sense of this data has not left me time to continue reporting disasters that have little historical context and no one seems interested in reading about unless they are personally affected by them.

However, Derna’s long history tracing back to its settlement by Greeks around the middle of the 7th Century BC, and some strong geological markers I now understand give some very solid evidence regarding the extreme nature of the recent event. Also, around 650 AD three of the Prophet Mohammad’s followers who were martyred along with ~ 67 fighters in the First Islamic Conquest of North Africa were buried on the bank of Wadi Derna. Their graves have been marked and venerated since then and memorialized with proper shrines and then eventually with Derna’s largest mosque. Overnight on Sept 11, the shrines, the graves, and “meters” of soil below where the graves had been were erased in the cataclysm. That’s evidence that Derna never had a comparable flood in a millennium and a half.

The geological evidence is orders of magnitude more extreme: Deltas form at sea level. The last time the sea level was 7-8 m higher to enable the formation of the present deltas was during MIS 5e in the Eemian era of the Last Interglacial Maximum around 123,000 (or less likely 118,000) years ago. The geological history of Cyrenaica shows that this area has been very stable over this period, suggesting that the three fossil deltas (including Derna’s) found along this part of the Cyrenaican coast could not have been formed any more recently than 118,000 years ago! Until Sept 11, the wadi’s that built the deltas reached the sea via spouts 5-7 m above sea level. As is the case for Wadi Derna, the other two wadis also eroded beds beds to reach sea level significantly inland from the elevated spouts that existed the day before. This is rock solid evidence that the last time weather was this extreme was more than 100,000 years ago, i.e., 100 millenniums ago when the deltas were built!

This work should be published before the year is done, when we’ll be gearing up for more elections.

In any event, if we don’t stop and reverse the still accelerating global warming, we can expect even worse to come as air and ocean temperatures continue to rise to extremes not seen for millions of years.

The farce of COP28 shows that the only way this reversal will happen is if concerned citizens can take back control of our governments from the fossil fuel special interests. To do this a majority of people must convince or replace their elected representatives to actually work for their survival rather than working to feed the greedy special interests.

Lethal Humidity for Derna – a 9/11 event in the climate crisis

(Rev. 2 – 29/10/2023)

Water was the cradle and mother of all life. When the world is too hot it is also the destructor that erases life, as in Derna, Libya on 11/09/2023

Life originated in the sea, dependent on and driven by water based chemistry. When our remote ancestors colonized the land more than 300 million years ago they had to carry enough water in their bodies to keep the organic chemistry of life working. Even today, between 50 and 60% of our body weight is the water surrounding and supporting our metabolic chemistry — truly water is the cradle of our life. Water-based chemistry is also controlled by temperature. Most of life’s chemical processes are facilitated and regulated by proteins called enzymes. Protein structure and function are strongly dependent on the temperature of the surrounding water. Water temperature also affects the rates of chemical reactions irrespective of any changes do enzymes.

For billions of years, complex life on Earth has evolved to live in a temperature range between water’s freezing point and a maximum of 35-45 °C. Mammals (like us) and birds who have evolved evaporative cooling (e.g., sweating) can survive somewhat higher environmental temperatures for a while if they can maintain the flow of water through their bodies. However, if our body temperature rises more than a degree or two above 40° for more than an hour or so it’s lethal because enzymes begin to denature and the chemical processes in our body cells no longer coordinate the keep us alive. We die ! (ref Wikipedia Colonization of land, Thermoregulation, Human body temperature).

As our planet grows ever hotter as a consequence of human’s industrial conversion of fossil carbon into greenhouse gases, rising temperatures are triggering a growing range of extreme and increasingly lethal ‘weather’ events. Many of these involve the effects of excess heat working with the physical properties of water — and we are far from understanding all of the implications for understanding this.

The latest example of lethal humidity at work was the rapid intensification of tropical rainstorm Otis in less than 24 hours into the “apocalyptic” category 5 hurricane that struck the tourist town of Acapulco on the Mexican Pacific coast around 1:00 AM on 25 October, 2023. None of the forecast models run on the 14th predicted that it would even become a hurricane at all. And then there’s Tropical Cyclone Lola, the earliest cat. 5 cyclone ever recorded in the Southern Hemisphere that has just savaged Vanuatu on the same day.

Last month’s example of lethal humidity working in unprecedented ways is presented below.

During the dark early hours of Sept. 11, 2023 hot water demonstrated the power of humid air to erase life in the the normally dry drainage upstream from, and in the center of the Libyan city of Derna in a cataclysm never before seen in its ~2,600 year recorded history.
This satellite imagery can be viewed by anyone with a desktop computer by downloading the freely available Google Earth Pro (Windows, Apple, Linex), searching for “Derna, Libya”. Vision beginning with Planet Earth will zoom into about 8 km above your requested location. If you then search for “Al Sahaba Mosque” vision will zoom in to about 1 km showing the latest high-resolution satellite imagery of Derna’s center from late morning on Sept 13, around 56-58 hours after the peak of the cataclysm. Using your mouse wheel you can zoom in to ~12 m above the ground where you can readily see the ant-like shadows of individual survivors crossing the now dry wadi on foot, and the first attempts to make temporary roads to reconnect eastern and western parts of coastal Libya. Earth Pro also provides access to historical imagery (click the Time Time icon) allows you to travel back in time through historical imagery. The most recent imagery (also providing the highest resolution) prior to the cataclysm is from June 19. This provides the “before” vision of Derna. Unfortunately the post-cataclysm imagery has only limited coverage. The image above, at one edge of a Sept. 13 tile crossing the wadi provides the before and after in a single image. The image below compares the before and after of the mosque and the area to its north. The red lines are sight lines and measurements left by various measuring tools I used in trying to understand and reconstruct what what happened here in the early hours of Sept. 11.

The idea of “lethal humidity”

I was reminded of the fact that humidity can be lethal by Dr Andrew (“Twiggy”) Forrest’s recently initiated speaking tour on the climate emergency to economic forums, world leaders and top universities in the world. He stresses that if global warming is not stopped and reversed, a major killer will be heat deaths caused by the growing heat accompanied by excessive humidity from the increasing amount of water evaporated by the high temperatures.

Forrest, one of Australia’s leading multi-billion dollar mining and industrial carbon emitters, has accepted the reality that global warming caused largely by his and other industries will cause near-term human extinction. He began broadcasting his concerns and the absolute urgency of stopping and reversing the warming if we are to avoid social collapse and subsequent extinction. He first raised this at the Boao Asia Forum — sponsored by China in Perth on 30 August (transcript here), and more recently at Oxford University (video below) – the start of a global lecture tour to key universities around the world accompanied with meetings of world leaders and at COP 28.

As Forrest said in the Boao Address, this is not a concern for the future, but right now! Substantial numbers of people are already being killed by the accelerating warming. The main killer will be what he calls “lethal humidity”. As noted above, if the air is too hot, and humid as well, without air conditioning we die within hours. (He says that survival in these areas will depend on air conditioning – assuming the power doesn’t fail). Forrest stressed that large areas of the world, including areas of India, China and America are crossing that threshold right now. These points were reiterated and expanded on in a lecture and “Fireside Chat” at Oxford University .

In the “Fireside Chat” sponsored by the Rhode’s Trust, Forrest expanded considerably on his ideas expressed at Boao and lecture covering the urgent and critical need for people in general to force governments and industry to act seriously on climate change. This Q&A ‘chat’ runs for another hour, but is well worth listening to if you have any concerns about futures for yourself and your family members.

My Climate Sentinel News article following up on the Boao address, Billionaires & action groups can save the world together! summarizes the contexts (including his ‘time out’ from empire building to earn a PhD in marine ecology) that led Forrest to his current mission — and what the climate and environmental action movement needs to do to assist the global mobilization needed to stop and reverse the warming process.

However, as strongly as Forrest stresses the dangers of the heat deaths humidity will cause in our progress towards global extinction, high humidity can also be even more catastrophically deadly in other ways.

The lesson of Derna, Libya is that humidity can lead to the destruction of not just human lives, but all visible life in given areas, and even the infrastructure created by humans or any other evidence that life ever existed in those areas.

Another way too much water in the atmosphere will kill us

On 10 September, 2023, the ancient and small but relatively prosperous port city of Derna, Libya had a population around 100,000 people. Its history traces back to the settlement of Cyrenaica (the eastern, coastal part of Libya) by the ancient Greeks in the 7th Century BCE. It was an easy place to settle because the inland plateau area was suitable for agriculture and the small delta of the wadi draining the plateau offered a reasonable area of flatish land close to sea level on the normally steep shoreline for a port and settlement. Since Derna was settled it has been a secondary port city that served at various times as a regional capitol that was comfortably wealthy from the agricultural productivity of the hinterland during periods with adequate rain and its proximity to Rome on the other side of the Mediterranean. Under Muammar Gaddafi, Derna benefited from Libya’s oil revenue.

However, due to Derna’s location on the sediment fan (or delta) formed at the mouth of a relatively steep wadi draining somewhat more than 500 km², it has been subject to occasional damaging floods. But nothing remotely comparable to the 11 September cataclysm had ever been recorded before in Derna’s 2,600 year history.

What happened in the early hours of 11 September literally ‘erased’ more than 20% of the city and more than 10% of its total human population from the earth. Derna warns us that water, the cradle and mother of all life (can and will destroy most of that life if we allow the planet to grow much hotter than it it already is.

“Evaporation” is what happens as individual H₂O molecules break free from a liquid mass of water to form the gaseous phase or vapor of water that basically dissolves in the atmosphere. As liquid water warms, the rate of evaporation increases up to a limit determined by the pressure of other kinds of gases forming the atmosphere. If the vapor molecules become frequent enough they will begin to stick together to “condense’ back into the liquid state. it takes a lot of extra energy for a water molecule to actually evaporate free of a mass of liquid water. This energy is released as the “heat of condensation” when the water molecule returns to the liquid state. The rates of condensation and evaporation vary significantly with changes of temperature.

Aside from controlling the rates of evaporation and condensation, temperature also strongly influences how much water vapor can dissolve into the air before it starts condensing. As air temperature increases, the amount of water vapor it can carry before condensation begins also increases about 7% for every °C of temperature increase.

Global 2 m (‘surface”) air temperature has been in in world record territory since the end of May this year. Sea Surface Temperture has been been in world record territory since mid May (more than 7 MONTHS!). Hotter water evaporates more water vapor, hotter air absorbs and transports ever more water as vapor.

“Gas Laws ” relate air pressure, density of a given mass of air. As air warms it absorbs energy to become less dense by expanding. As it cools, its density increases and heat is released. In the atmosphere this leads to convection. with warm air rising and cooling as it expands while tending to cool further by radiation of excess heat to space until it cools enough that again becomes dense enough to sink alongside rising hotter air.

More details of the physics of water, how its various states are measured, and water’s implications for weather can be found in my mailing to politicians, “Act Now – Later may be too late” and in the related “Global Climate Change Now“.

My presentation linked below makes the case that Derna demonstrates how heat and too much water in the atmosphere can do far worse things than just cooking people by preventing evaporative cooling. The more water vapor in the atmosphere the more water there is to drop on the land, and the more heat energy there is available to force wet air masses high in the sky to squeeze out the last drop of what was already an excess load of water as rain and ice (the freezing of ice from water releases still more energy (the energy of fusion) to drive the weather to even further extremes.

Where Derna was concerned, another consequence of having several unbroken months of high temperatures setting daily and occasionally all-time records, the jet stream system that normally keeps cold spots and warm spots moving around the world basically broke down — becoming very weak and chaotic. The combination of record high land and sea temperatures over summer with stalled heatwave conditions all around the Mediterranean provided optimum conditions to load the atmosphere with a truly prodigious amount of water. The availability of so much water and heat energy resulted in the formation of Storm Daniel. With little or no jet stream, Daniel was left to wander more or less randomly around the eastern Mediterranean. Daniel first dumped more than 700 mm of rain were dumped on areas of Greece to flood more than a third of that country’s prime agricultural lands, and then more than 400 mm on the Libyan city of Al Beyda a few km west of the upper end of Wadi Derna’s watershed. These numbers are already crazy & incomprehensible, but a fluke of bad luck associated with the particular landscape of Cyrenaica may have added even more kick to the already stupendous amount of peak water in the pipeline provided by the wadi. The catchment’s main reach on the plateau behind Derna runs from west to east, and it’s probable that Daniel’s rain cells were also moving from west to east at a comparable speed to the progress of the flood peak down the Wadi.

In any event, except for the last (possible) fluke, this kind of increasing storm intensity is a predictable product of global heating — which is what makes the Derna situation so alarming. If we allow the world to continue heating at an ever faster rate (as driven by Earth’s Energy Imbalance), lethal humidity will soon be be cooking so many people and trashing so much infrastructure needed to feed ourselves and condition the ever hotter air to a livable temperature we will face social and ecological collapse. If this happens humans will no longer have the capacity to do anything further to stop the runaway warming that will put all of the accessible soil and organic carbon back into the atmosphere. The worst global mass extinction event in Earth history so far will then run its course unhindered.

The presentation ends with a possible silver lining — humans working together can do very remarkable things if sufficiently motivated. I’ll write more on this later, below.

Some comparisons to think about

Japanese earthquake and tsunami of 2011

Several of the commentators on the Derna cataclysm said it was like a tsunami. I spent a couple of months trying to measure the impact of the Japanese Tohoku earthquake and tsunami of 2011 that led to the destruction of four of the Fukushima Dai Ichi nuclear power plants from the vast array of news, social media postings of videos, and the Google Earth record. Obviously, the tsunami affected thousands of kilometers of coastline, but nowhere did the 2-3 waves of the tsunami as comprehensively erase the evidence of human existence as happened in Derna.

[Google Translation of title] “Great East Japan Earthquake] People fleeing the tsunami in Minamisanriku Town, Miyagi Prefecture (different angle)”. This is a snapshot from https://www.youtube.com/watch?v=e_vIGlCk6ME There were countless videos like this (many now no longer accessible). Note that most of the structures being destroyed were wooden houses that were floated off their foundations before being crushed in the melee.
The comparison here is from the Japanese fishing port city of Minamisanriku of an area approximately 60% the size of the area depicted in the first graphic of this post from where one of its rivers meets the sea. Here, concrete buildings remain intact and except for the river mouth where significant soil has been removed, roads and the concrete slabs and foundations of buildings remain relatively intact. Boats in the upper picture were all destroyed, cast on the land or dragged out to sea on the return waves.

At Rikuzentakata, one of the worst hit cities, the tsunami wave reached heights of 13 meters (third floor of surviving buildings), and possibly killed 10,000 people. Wooden structures were completely demolished, but roads and concrete infrastructure remained largely intact as can be seen in the large trove of imagery accessible via Google.

Unlike a tsunami that normally involves only two or three killer waves at the most, Derna’s flood seems to have lasted several hours – long enough to strip everything away more-or-less down to bedrock!

Possibly cataclysmic valley floods in other parts of the world

My first contact with cataclysmic flooding was in the summer of 1976, when I was teaching for a year on a temporary appointment at the University of Colordo in Boulder, where I was a near witness to the deadliest disaster of any kind in Colorado’s history. One very muggy (humid) afternoon a very ominous and noisy system of dark clouds and lightening passed over the university. I thought of possible tornadoes, but no rain was falling yet. Soon after this the storm cell got stuck in the valley of the Big Thompson River draining Glacier National Park ~ 45 km north of Boulder along Rocky Mountains forming the Continental Divide. The humid prevailing winds from from the prairie at around 1,600 m altitude were trying to push the storm over the Divide. The upper (western) third of the Big Thompson catchment is surrounded on three sides by ridges more than 3,500 m high (as can be followed on the clear contours of Global Watersheds‘ “Topographic” or “Thunder Forest” base maps). The storm cell dumped 300 mm in less than 4 hours. The resulting flood formed a “wall of water” more than 6 meters high that rushed down the steeply sloping canyon (2.4% gradient for the last 3 km — as measured to the accuracy allowed by Google Earth Pro) at a speed estimated to be 6 m/sec with a discharge rate of with a discharge of 1,000 cubic meters per second, killing 143 people (mostly campers).

As measured in the “slow lane” on the flat land in front of Al Sahaba Mosque well before the flooding reached its maximum height (upper floor of the main mosque) and erased the shrines and the 1,400 year old graves of the Companions of the Messenger of God, the water there was already moving at around 4 m/sec well before the flow reached its peak height. The peak speed over the wadi itself was probably two or three times what was measured in the Big Thompson flood!

When the flood happened, I was living in one of the University’s faculty flats situated alongside Boulder Creek. This has a drainage of 340 km² and cuts Boulder in half (a city that was then comparable in size and relative affluence to Derna with its Al Sahaba Mosque). I immediately considered what happened at Big Thompson and soon found other lodgings. Big Thompson had less sever another flood in 2016 that also caused substantial damage. So far, Boulder has been lucky.

Other potentially dangerous river systems

Other river systems with deeply incised valleys capable of producing cataclysmic floods under appropriate conditions that I know personally because I have lived in their neighborhoods are Melbourne’s Deep Creek-Maribyrnong system above Footscray and the Yarra River above central Melbourne. The Maribyrnong catchment above Footscray measures 1,300 km², and the Yarra river catchment at Kew (deeply incised from Warrandyte through Kew) measures 3,900 km² (or 5,500 km² measured at its mouth Port Philip Bay that includes the Deep Creek-Maribyrnong as a tributary). Both the Yarra and the Maribyrnong have flooded, with the Maribyrnong having its worst flood in several decades this time last year. Derna style floods fueled by high temperatures and lethal humidity would have unimaginably worse consequences for the cities these rivers flow through. (Note: the free Web ap, Global Watersheds, will plot the watershed extent and area for any point on the land in the world on a range of base maps. For understanding the landscape, I recommend “Satellite” – good but several years out of date, and “Topographic” or “Thundercloud” for clearly labeled elevation contours).

Catchment map from Global Watersheds, Google Earth Pro image from 22/04/2023. The controlled concrete spillway is located at the upper left edge of the dam, with the engineered topographic “natural” spillway near the lower right. This can be examined in more detail in Google Maps’ satellite view.

Possibly Victoria’s most dangerous drainage is the Campaspe River draining into the Murray Valley Vote Climate One’s home base in Kyneton is located in the middle of this catchment that begins just over the hill from where I live. The river is held back by Lake Eppalock, formed by a 650 m long embankment dam (i.e., similar to Derna’s mud-pie dams) that at full supply holds back 300,000 megaliters of water (possabably 1000 x as much as the Derna dams) from a catchment above the dam of 2,100 km². Unlike Derna’s dams that had no provision to manage spillage over the top of the dam. Eppalock has a well designed “controlled” concrete spillway with a maximum capacity of 8,000 m³/sec, as well as two “emergency” spillways enabled by the existing topography. [Based on Global Watersheds topography and Google Earth, the second emergency spillway is no more than a narrow topographic low that could pass only a small fraction of the volume passing over the engineered spillways.] In October last year, (and once in 2011), with the dam at 130% of full capacity, flooding exceeded the capacity of the controlled spillway with an outflow of 103,000 megaliters a day! (more than a third of the lake’s entire capacity at full supply in one day!).

Excellent drone vision is available for the effect of this outflow on the spillways, i.e., erasing the road along the top of the emergency spillway and scouring away the earth down to the bedrock forcefully enough to eat into the rock itself. Fortunately the scouring did not reach the concrete leveling wall designed to ensure that the overflow was spread uniformly across the very wide spill area to minimize concentration of the erosive flow of the water on small areas.

Arrows point to the deepest gouges eroded into the basement rock. Some of the erosion is a result of the prior spillage of the reservoir in 2011, but it is clearly deeper here. The leveling wall is clearly visible along the bottom of the graphic

Even more detailed imagery of the functioning of both spillways and very real damage sustained by the emergency spillway during and after the 2022 flooding is provided by Joel Bramley Photography.

Noting that the 2011 and 2022 floods were caused by ‘ordinary’ decadal scale extreme weather events, one wonders whether the dam would survive a Derna scale cataclysm.

The Wadi Derna dams across a topographically sloping drain could only hold small volumes of water limited by the dimensions of the sloping drain and height of the dams and were completely empty until Daniel arrived. By contrast Lake Eppalock is on the edge of a plateau where the topography allow the storage of many times the volume of water of the gorge immediately behind the dam. At full supply, Lake Eppalock has three main reaches. Two are approximately 10 km long, and the third is 5 km long. In places each of these is more than a km wide. Unlike the Derna dams, Epalock has well engineered spillways to minimize the likelihood of overtopping and it’s maintained. But, very much like the Derna dams, it is a ‘mud pie’ construction susceptible to cracking and slumping (especially if overtopped):

  • Significant cracking was observed on the crest of the main embankment at Lake Eppalock for many years, but in recent years increasing movement upstream [slumping?] during low reservoir levels indicated a progressively deteriorating stability situation. Investigations also revealed cohesive filter material [clay?] that would allow a crack to propagate. A fast-tracked [emergency?] remedial works program was completed in 1999 to rebuild the highly vulnerable upper rockfill shells and filters, both upstream and downstream. [Davidson et al., 2000. The Dam Safety Upgrade at Lake Eppalock]

Downstream, the Campaspe cuts through the center of the small farming town of Rochester, 56 km N of the Eppalock Dam. The 103,000 megaliter/day flooding over Eppalocks’ spillways soon flooded around 1000 of Rochester’s 1500 homes on its way to meet the also flooding Murray River in Echuca rising higher and causing a lot more damage than the 2011 flood, which was the first time Lake Eppalock spilled over the emergency spillway. Today, half of the flooded homes are still uninhabited, with some of the repairs expected to take another year for all of them to be completed because it seems there is no capacity left in the system to finish the work any sooner.

The end game

The stark reality is that climate change, currently driven by Earth’s exponentially growing energy imbalance, is already stressing human society to the point that we cannot even maintain a status quo where we are able to repair extreme weather damage as fast as it occurs. As cataclysm and catastrophes increasingly concatenate and overlap due to continuing global warming, resources and capacities will decline at an ever faster rate, until society can no longer avoid collapse into chaos and barbarism, and then near term extinction.

We are truly facing an existential emergency. If we cannot mobilize the the scientific, technological, and human resources reverse the imbalance to slow, stop, and reverse global warming in the very near term, the exponential growing feedbacks (primarily carbon emission from soils, permafrost, oceans and accessible fossil sources) that are driving the energy imbalance will be unstoppable until all the accessible carbon has been transferred to the atmosphere as greenhouse gases. By then humans and most other complex organisms on Earth will be extinct.

Personally, I think humans, if they can work in a focused way and cooperatively together to fight the common enemy, actually have the capacity to stop the lethal feedbacks while they are still in their early stages of ramping up. This thought is based on 14 years focused and in-depth research and writing on the co-evolution of humans and our technologies, 17 years working as an engineering knowledge management systems analyst and designer for what was then Australia’s largest defence project engineering and construction organization, and a lifetime student of evolution grounded in physics and Earth and marine sciences.

I am also old enough to remember the end of WWII and am fully aware of how America entered the war as a disunited mob of apathetic to passionate pro fascist isolationists to pro communist utopians. Yet, within weeks of being dosed with the reality of the Japanese bombing of Pearl Harbor, the mob united, turned scientific glimmers into totally new sciences, technologies and logistcs, crafts into massive assembly lines, and anarchic mobs into war machines. The global war was won in Europe with America’s help with the German surrender on 8 May 1945; and by America in the Pacific with Allied help with the Japanese surrender on 2 September 1945 after the atom bombing of Hiroshima and Nagasaki on 6 and 9 August (well under 4 years). This was followed up by the formation of the United Nations (a good start towards global government), and the restoration of many nations to a road to prosperity under the Marshall Plan.

The realities reviewed above show that humanity is currently facing the most lethally dangerous crisis in our evolutionary history, probably even more extreme than the End Permian mass extinction event that our ancestors survived 250 million years ago. If we accept this reality it should motivate us to work together collectively with the necessary focus and discipline to put the Apocalyptic Horsemen back into their mythic stable in God’s Scroll so we can escape from the down-hill highway to Earth’s Hothouse Hell (see also David Spratt’s series on Climate Code Red).

Billionaires & action groups can save the world together!

Dr Andrew (“Twiggy”) Forrest tells international business and political forum the factual reality that “Business will kill your children!”

When I started this essay, Renew Economy, whose article is linked below, was one of the few mentions I found in the press or social media of the unique event where any self-made billionaire, let alone an Australian, stated simply and with honesty that his business kills our children and puts human survival at risk. He asks for help in making him, his industry, and business in general to stop carbon emissions. Simultaneously, and blissfully unaware of what Andrew Forrest was saying, a collaboration of climate and environmental action groups was organizing an emergency meeting, #SteppingUpTogether, for Melbourne Town Hall to crystallize a coalition of (hopefully ALL) such groups to provide precisely the kind of help Forrest was asking for.

Both Forrest and the people at Melbourne Town Hall accept that it may already be too late to avoid the existential climate catastrophe.

However, by working together, he and we may actually be able to defeat global warming, and work our way off the highway to Earth’s Hothouse Hell to find a probably rough and narrow road to stewardship of a habitable world with a sustainable future.

“Business will kill your children:” Was Andrew Forrest’s climate speech really that “loopy”?

Giles Parkinson — 4 September 2023 in Renew Economy

It was the sort of speech you [would be lucky to] hear from climate scientists and climate protesters; a presentation stunning in its simplicity and series of one liners.

“It is business that will kill your children,” Forrest declared. “It is the beginning of the end.

“Humanity it at risk. Now.”

Read the complete article… Listen to Forrest’s speech on YouTube… Read the parsed and formatted transcript

At $US 21.7 Bn, Forbes Australia’s Richest in March placed Andrew Forrest second (after Gina Rinehart at $US 30.6 Bn) amongst the motley crew of billionaire miners, tech sector high flyers, and property developers, most of whom seem to be more concerned to build even more personal wealth than they already have. To many in the climate and environmental action movement, these billionaire business people are the class enemy. It is their industrial businesses that are largely responsible for driving Earth’s climate system into what now looks like runaway warming. Warming that will lead to climate catastrophe and probable extinction at the end of the downhill highway to Earth’s Hothouse Hell.

Yet, Forrest’s 24 minute speech, delivered Aug 30 in Perth at the Boao Forum Asia (29-31 Aug — sponsored by China) and linked above, is the complete antithesis of what you would expect to hear from one of the self-confessed perpetrators of the currently accelerating climate catastrophe threatening us.

Amongst other things, the speech: ● confesses and condemns what business has done to put human survival at real risk; ● gives a meticulously and gorily detailed description of one of many ways that the business triggered climate catastrophe will reap human lives along he road to extinction; ● expresses Forrest’s promise and “steely determination” that he and ALL of his industries are committed to reach absolute zero carbon emissions by 2030 [I’ll have more to say about this promise below] — both to stop emissions from his business, and to show the world that it can and must be done; ● asks that China, India, and the USA step up together to legislate and subsidize doing whatever it takes to achieve what he is showing can be done; and, finally, but by no means least, ● Forrest begs citizens and consumers around the world to make governments and businesses do these things:

This is what I’d like to put out to you as members of the Boao Forum.

This is not my idea, or any single person’s idea.
If this is our idea in the Boao Forum, this is what I ask you to consider during the course of
this day and decide:

Do we want a member’s resolution of our forum to ask that discussions proceed at the G20?

That intention to proceed with law happens at APEC and that the business people of the
world gather BOAO Forum for Asia next year and work out how to do it.


Business people, if we are not fighting with our own governments, [we] can leave this [meeting] and make it happen….

and that’s what I’m asking [for], a simple agreement led by business.

Fast! …..Because it’s business.

I need you tonight….

It’s business which is causing global warming….

It’s business which will kill your children.

It’s business which is responsible for lethal humidity.

But it’s policies which guide business!

YOU MUST HOLD US TO ACCOUNT!

Don’t let us with our clever advertising blame

You — the consumer; or

You — the public or individual…..

That’s rubbish.

Business guided by government will either destroy or save this planet.

Hold us to account, the power of You!

Thank you…. Make us change….

That’s all I’m asking you to do.

MAKE US CHANGE….

Thank you very much.

YOU MUST HOLD US TO ACCOUNT!

Hear and watch Dr Forrest say this!

To understand greatness and gravitas of Forrest’s address and its implications for all humanity takes your patient and careful attention to his actual words and your awareness of several contexts surrounding the lead up to the conference. Of course, in the case of Australian media, his content and intent were so incongruous that it took two or three days into September before there were many reports at all.

Murdoch and the financial press (often the same) responded to Forrest’s attack on fossil fuel and gory details about how heat kills people by claiming that he must have lost the plot to ever increase his personal wealth due to a brain seizure or having gone troppo — bad news for his shareholders. Even usually progressive and climate action friendly press such as the Saturday Paper, Crikey, and the Guardian seem to have missed the point. However, in the last few days more articles, accepting that the speech was actually important, have given more thoughtful attention to its actual content (e.g., see ‘Twiggy’ Forrest: Climate messiah or billionaire opportunist?, from Sept. 13). But, even here, commentators seem to have real difficulties seeing past what they assume must be Forrest’s overwhelming drive to become even richer.

Personally, I think these commentaries trivialize and miss the major thrust. This man from the bush is staking his fortune, career, family — and everything else…. To crystallize a critical transition:

From: corporate business as usual — working for immediate profits that are far more important than even human survival in the face of the growing climate catastrophe.

To: business working to build a healthy society that can sustain itself into the foreseeable future.

What has Andrew Forest actually said?

In my diverse careers in science, teaching and corporate knowledge management, I learned that speech has a low bandwidth for communicating detailed facts and knowledge. You have to listen to strings of words before their meaning and import are clear. As Walter J Ong observed in his classic work, Orality and Literacy: The technologizing of the word, speech disappears in the instant of its impact on the ear-drum of the listeners. All that is left are fading impressions in the hearers’ brains that were influenced by all kinds of extraneous perceptual and cognitive issues, to say nothing of preexisting memories and biases. In other words, we often only hear what we expected to hear, not what was actually said, and certainly not everything that was said.

Because, on first listening to the speech, I thought that Forrest had said some very important things. His speech was important enough that I needed to read, and re-read it in a printed transcript. Not only is reading far faster than comprehending the spoken word, but it is much harder to misread than to mishear. And, if you missed something or are unsure what was said, you can re-read the work as many times as it takes. And if there is a video of the speech, you can go back as often as you want hear and see HOW it was said.

The only transcript I could find was YouTube’s totally unparsed and unpunctuated speech-to-text (click the three dots at the end of YouTube’s video menu bar, and select “Show transcript”). In any case, I had to do the parsing, punctuating and formatting of the text myself to be sure I understood it. I had to look at each word, and pick out each thought and sentence in the sequence and then parse out the thoughts on the screen/paper. Where there was any chance of misunderstanding (YouTube’s transcript has some fascinating garbles, e.g., 23 secs, in “Minderoo Tatterang” becomes “military”), I had to go back to the original speech and its various contexts to be sure that the transcript actually recorded the spoken word(s).

The deeper I got, the more impressed I was with the total precision and clarity of Forrest’s expression. Almost without exception, every single word was precisely chosen and placed to unambiguously convey a particular thought. He said exactly what he meant, and totally meant what he spoke.

Forrest must have put a great deal of thought and rehearsal into crafting the talk; and based on the hoarseness of his speaking, he had also been doing a lot of talking (arguing?) in the lead up. By no means was there anything sham or trivial about the talk.

As many of those commenting on the address dimly recognized, this is a pivotal turning point in Forrest’s personal and professional career. This giant of a man who arrived at the 20th Anniversary celebration of his mining company on one of his many 3 story tall dump trucks was once a jackaroo from the WA bush.

Forrest is betting his entire fortune, body, soul, and family on his understanding of Earth’s climate crisis and what he thinks he can do personally and via his business empire to help humanity find a sustainable pathway to an extended future.

I don’t think there is anything particularly messianic about this. Forrest is self-made, he knows his limitations and his very real capabilities. He has assessed that he has the capabilities to be an agent of changes that must happen if humanity is to survive the present climate crisis. “Again, someone has to do it. “And I just think, ‘If not me, then who?’ ” [quote from SMH 2/072022]. And if he hasn’t at least tried…. then emissions from his mining activities have been at least partly responsible for the end of humanity.

Definitely not a messiah, but perhaps a redeemer?….


Forest has placed his bet, turned the roulette wheel, and rolled the ball (the image is from his presentation).

He is helping us, …..so all those of us in the climate and environment action community need to hold him, business and government to account, so the ball falls in the correct slot for all of us to win the “one in fifty chance of 1.5 °C holding”.

Critical Contexts

Andrew Forrest more-or-less grew up in WA, on the Forrest family owned Minderoo Station (when he wasn’t away attending school), a 2,400 km² sheep and cattle station traversed by the Pilbara’s Ashburton River and 95 km E of Exmouth across the Exmouth Gulf.

He may spend more time on corporate jets than on horseback these days, but the fact that he hails from the wide open spaces is an important part of Andrew Forrest’s mystique. He likes to remind us that the red dust of the outback is deep in his pores – that even when he’s sporting a dapper navy suit, his mindset is that of a man in moleskins.

After meeting US President Joe Biden at COP26, the UN climate conference in Glasgow last November, Forrest accepted an invitation to visit the White House to continue the conversation about green energy. Describing how he felt as he entered the West Wing in April, he says: “Ex-jackaroo. Kid from the bush. So fortunate to be able to do this.”

Mounting debts had forced Forrest’s father, Don, to sell Minderoo Station in 1998. When the property came back onto the market 11 years later, Forrest sent two bidders to the auction – “just in case one had to go to the toilet or had a heart attack”. He bought it for $12 million and has spent millions more turning the station into a showpiece. He says he does his best thinking there. The place is full of memories, not all of them good.

When Forrest was a boy, just eight years old, he noticed smoke on a distant part of the property. Lighting a fire was the accepted method of sending a distress signal, so he and Don went to investigate. A man had been working on the engine of a bulldozer when it jumped forward and pinned him against a gum tree. He had managed to light a fire but it burned back towards the tree and engulfed him.

“When we got there, we found this charred but breathing body,” says Forrest, who travelled with the man in the back of the Land Rover on the long drive to hospital. “He could just speak and he said, ‘Sing me some nursery rhymes.’ ” Forrest held the man’s hand and sang to him until he died. He tells me during our lunch at Cottesloe that it was this experience, more than any other, that shaped him. From then on, he understood at a visceral level that life was short and not a day should be wasted: “I do tend to treat time as being incredibly precious.”

Time is valuable to Yindjibarndi leader Michael Woodley, too, and he has spent a lot of it slogging his way towards legal recognition of his people’s ownership of land on which Fortescue mines. “Everything is about Andrew Forrest. His image. His brand,” says Woodley, who contends that if Forrest has been able to live a large life, “it’s because of the wealth that he has generated from our country. That’s what money does, right? It turns you into a superstar.”

Jane Cadzow, SMH Good Weekend, 2 July 2023, From mega carbon emitter to … eco-warrior? What drives Andrew ‘Twiggy’ Forrest…. Read the complete story!

Immense wealth also gives some people immense power to do things mere mortals can only dream about…., like saving human existence. In 2001 Andrew Forrest and his wife, Nicola, established Minderoo Foundation (named after his boyhood home) with part of their Fortescue wealth to work towards making our shared planet a better and safer place for people to live. As at 20 June, 2023, the Forrests have donated a fifth of their Fortescue shares to the Foundation (about $5 Bn), bringing its total endowment of the Foundation up to about A$7.6 billion).

“As our world faces enormous challenges, we have elected to continue to use our material wealth to help humanity and the environment meet these existential risks,” Dr Andrew Forrest AO said.

“Accumulating wealth should only be a small part of a person. Their contribution to their family and society is way more important. Other skills such as carpentry, farming, the arts, working in construction or for government are equally as important. If you happen to be good at accumulating wealth, then I believe in using that skill for the greater good.

“This is why we will continue to donate our wealth to causes where we can make a sustainable difference.”

https://www.minderoo.org/news/andrew-and-nicola-forrest-donate-one-fifth-of-fortescue-shareholding-to-philanthropy

Of course, Forrest presumably still controls how those deeded shares are voted. He may have ceded the capital and income they represent, but most likely still controls the power they represent.

Another large tranche of his family wealth is devoted to a private investment group with a very strong social and environmental policy called Tattarang (see also Wikipedia).

The name Tattarang pays tribute to a fiery but caring stallion that was owned by Andrew Forrest’s mother and cherished by all at the Forrest family’s Minderoo Station during the 1950s.

In a joint statement, Andrew and Nicola Forrest said: “The name Tattarang has held a special meaning in our family over many years and was the inspiration to rename our commercial group. For us, Tattarang signifies the unique bond of trust that is formed between a rider and their horse, and the seriousness each party invests in caring for and protecting the other.”

The Forrests said they wanted business to play a greater role in changing the world for the better.

“The way you earn your money will have a greater impact than the way you choose to give it away. Business is critical to improving the world,” added Grace Forrest, Director of Minderoo Foundation and Co-founder of Walk Free.

The Tattarang group entities remain separate from Minderoo Foundation, the philanthropic entity founded by Andrew and Nicola Forrest. As part of the name change, Tattarang has launched a new corporate website: www.tattarang.com.

Dr Andrew Forrest AO is Chairman of Fortescue Metals Group, the publicly listed company he founded in 2003, in which Tattarang Pty Ltd holds a 36 per cent shareholding.

https://www.tattarang.com/news/2020/the-minderoo-commercial-group-rebrands-to-tattarang/

Tatterang’s climate policy is strong:

The scale and severity of bushfires in Australia over the summer of 2019-2020 was a clear example of how increased weather volatility due to climate change is already contributing to the intensity and scale of natural disasters.

The time to act is now. Collectively, we must act with all speed and determination to reduce emissions and create pathways to achieve a net-zero emissions global economy. Climate change is already exacerbating environmental degradation and as a society, we must also adapt to protect human health and threatened ecosystems through environmental conservation measures, including effective plastic waste management.

We must act immediately if we are to effectively adapt to the impacts of climate change and to achieve net-zero emissions well before 2050. If we do not act, we risk leaving enormous challenges, and terrestrial and marine ecosystem-wide destruction to our next generation. Tattarang accepts this call to action.

Tattarang has commenced an assessment to estimate the emissions from its investments, activities and operations. This will provide critical data upon which Tattarang can implement a range of actions including the development of science-based emissions reduction targets and emissions avoidance and mitigation projects.

Tattarang: Our climate policy… Read it all

And then, who is this titan of industry and business, who thinks that he can tell us that we are all doomed to oblivion if we don’t stop global warming NOW, while we still might? Forrest has made himself into a genuinely qualified marine scientist, with an earned PhD to prove it. It’s a real thesis, based on real research — done in the midst of building his fortune….

Personally, I grew up on and in the ocean — face to face with a diversity of life far beyond anything that can be experienced on the land. I am an academic scientist. Marine biology was one of my teaching specialties…. It’s a real thesis….

[Eight] years ago, Forrest was hiking in the Kimberley when a ridge gave way and he fell into a large pool. One of his legs shattered from the kneecap down as it wedged in a loop of submerged tree root, trapping him underwater. The pain was excruciating and in wrenching himself free, he mangled the leg further: by the time he struggled to the surface, his foot was facing the wrong way. The accident may not have killed him, as for a few heart-thumping seconds he thought it would, but it changed him.

During his convalescence, as he moved from a wheelchair to crutches and finally back onto his feet, he had time for reflection. He decided to embark on a PhD in marine science, a field that had always fascinated him. For four years, he immersed himself in the study of pelagic ecology and, more broadly, the state of the world’s oceans. “It was there that I really came across the reality of global warming,” he says. By 2019, he was Dr Forrest, eco-warrior.

Jane Cadzow, SMH Good Weekend, 2 July 2023, From mega carbon emitter to … eco-warrior? What drives Andrew ‘Twiggy’ Forrest…. Read the complete story!

So far, the continuity of this interest is represented in real estate by the Exmouth Research Lab, a new marine biology lab he had built about 80 km across Exmouth Gulf from Minderoo heartland.

Is Forrest right about humidity being lethal?

The latest science says so. See: Vecillio, et al., 9/10/2023 in PNAS: Greatly enhanced risk to humans as a consequence of empirically determined lower moist heat stress tolerance.

Prospectus

I have parsed and reported what Andrew Forrest spoke to the world at the Boao Forum late in August, and analyzed the contexts from which the words came. What remains to be seen is whether the world will step up and unite to solve the existential crisis so forcefully laid out before us by this remarkable address.

If anyone has any residual doubts about Forrest’s sincerity, he has wagered control of his family and foundations’ fortune on being right (remember the imagery of the roulette wheel), and burned a lot of bridges along the way.

In his interview with 9News, following separation from his wife, Nicola, Andrew Forrest admits he’s hard to live with, and explains the high turnover of Fortescue executives: ‘My way or the highway [to Hothouse Hell]’. Several chosen the highway, and there may well be more. With his transfer of shares into Minderoo Foundation and voluntary settlement with Nicola, 9News reports that this moves Andrew from 2nd to 13th place in AFR’s Rich List (‘Nic and I are lockstep’: Andrew Forrest gives first interview since split from wife Nicola). This suggests he is left with a fortune of between $7.5 and $6.5 bn. Even if you assume that growing his wealth is Andrew’s main concern, he has risked ‘everything’ on his turn of the roulette wheel to decarbonize all of his businesses…..

If anyone can bulldoze his way through to convince our world leaders that they have to prioritize climate action above all else, Andrew Forrest has a better chance of doing it than any other person I can think of: Pope, UN Secretary General, David Attenborough, et al. But to make it stick, he needs coordinated support and cooperation from the bulk of society that I think the world’s climate and environmental action groups represents.

Some afterthoughts

VoteClimateOne.Org recently (9 September) participated in a recent emergency meeting of diverse climate and environmental action groups at Melbourne Town Hall called #SteppingUp Together focusing on how we might work together to advance action on the climate emergency. This was organized in part to begin establishing a structure able to help the (literally) millions of Australians belonging or subscribing to such groups coordinate their individual voices to make businesses and governments change their focus from promoting and subsidizing industries killing our children with carbon emissions to legislating and organizing the fight to stop and turn around global warming.

Although few of us at the #SteppingUpTogether meeting knew of Andrew Forrest’s Boao Address at the time, it stands as a clarion call to to mobilize the global war effort to defeat the existential enemy — global warming. It is no coincidence that the common goal to our diverse approaches is to give consumers and individuals tools to construct a common voice able to hold governments and business to account. We all see and understand the need to actually achieve what Forrest is calling for us to do!

Although the SteppingUp meeting was originally conceived to coordinate demonstrations and actions to convince the Government to stop fossil fuel export developments (especially in the Beetaloo Basin and Darwin areas), the crazy extreme deviations in global climate indicators (documented by Climate Sentinel News posts and in direct mailings to all Australian MPs) made the meeting a lot more urgent, with several important speakers being incorporated only shortly before we met. These last-minute additions included:

  • Assoc. Prof Mark Diesendorf, UNSW Sydney, was double booked so could not attend in person, but provided us with a couple of videos, focused on his research on how fossil fuel and other special interests have captured “captured” and control governments so they do their bidding rather than working for constituents’ interests. This gives the SteppingUp group a deep understanding of where and how we have to force change before our government will actually begin working in our interests. Diesendorfs’ ideas are fully laid out in his 2023 book (with coauthor Rod Taylor), “The Path to a Sustainable Civilisation: Technological, Socioeconomic and Political Change“. This helps us know our enemies….
  • Greens Senator for Victoria, Janet Rice, on “Building political power to tackle the climate crisis“, following a speech given in frustration the day before in the Senate Chamber in Canberra, “Chuck the denialists out!
  • Just back from the Northern Territory, Jane Morton, who helped bring Extinction Rebellion to Australia and co-convenor of Darebin Climate Action Now, who in 2016 instigated the first local council in the world to declare the climate emergency gave us a talk on some of her methodology.
  • Adrian Whitehead, who helped mobilize Darebin Council’s unanimous Climate Emergency Declaration, explained how CACE (Council and Community Action in the climate Emergency) can work up to higher levels of government, down to citizens, sideways to other councils, and inward to maximize local effort from the council itself to prioritize and enforce action on the emergency.
  • Charlotte Gallace, an amazingly poised year 9 student and school council member at Prahran High School, and also a school striker, presented the younger generations’ hopes that we would get our act together and leave her generation with a sustainable future.

SteppingUpTogether organizers had hoped that we could have at least one of the recently elected ‘teal’ community independents join us, but this proved impossible given their workloads while Parliament was sitting (both major parties have been happy to deliberately hobble independents by limiting each to only a single paid staff member).

Given the plethora and importance of these last-minute speakers, and the enthusiasm of our planned speakers to share their tools and ideas for changing the minds of currently ‘captured’ MPs, we had no time left for our planned workshop. However, you can be sure that we are already working towards assembling a user-friendly communications apparatus to share our practical knowledge and for coordinating public and MP-focused campaigns.

Given the urgency aroused by the crazy extreme and still growing indications that we already tipping into a hotter and more rapidly changing climate regime, you can be sure that within a few more weeks SteppingUpTogether attendees (and many other organizations) will be putting together a network facilitating the coordinated and collective involvement in public and MP-targeted campaigns of the millions of members belonging to one or more climate and environmental action groups.

End state capture!

Hold our governments to account: Make them work for Us — The Public…. The Consumers…. The Individuals.

Make the governments change…. Make the governments hold business to account….

Hold governments to account…..

Victoria first, then Australia, and then the world.

The hottest summer in human history – a visual timeline

Jonathan Watts, Lucy Swan, Rich Cousins, Garry Blight, Harvey Symons and Paul Scruton

From June to August 2023, a series of extreme weather events exacerbated by climate breakdown caused death and destruction across the globe.

As the world sweltered through the hottest three month spell in human history this summer, extreme weather disasters took more than 18,000 lives, drove at least 150,000 people from their homes, affected hundreds of millions of others and caused billions of dollars of damage.

That is a conservative tally from the most widely covered disasters between early June and early September, which have been compiled in the timeline below as a reminder of how tough this period has been and what might lie ahead.

For details and the complete timeline, read the complete article….
July 2023 @ 16.95 °C – hottest ever, by far; August 2023 @ 16.82 °C – second hottest ever! New regime stuff!

Implications

The current extremely low sea ice will have a range of impacts. Changed ocean stratification and circulation will alter basal melting beneath ice shelves48. Greater coastal exposure will increase coastal erosion and reduce ice-shelf stability49. Changes in dense shelf water production will alter bottom water formation and deep ocean ventilation50. Sea ice changes will also have contrasting influences on Adélie and emperor penguin colonies51,52, and substantially alter human activities along the Antarctic coastline.

Anthropogenic greenhouse gas emissions have been attributed as the primary cause of Southern Ocean warming, and here we suggest a potential link to a regime shift in Antarctic sea ice. While for many years, Antarctic sea ice increased despite increasing global temperatures6, it appears that we may now be seeing the inevitable decline, long projected by climate models53. The far-reaching implications of Antarctic sea ice loss highlight the urgent need to reduce greenhouse gas emissions.

The record for the 23rd blew the Canadian system’s off the chart! The following chart from Copernicus, the EU’s equivalent of NASA, that operates the satellites, suggests the data from the 23d is probably a real record of what the satellites actually recorded. In most years the wildfires would have been more-or-less through for the year. Yet 23 Sept shows BY FAR the largest number of hotspots recorded for the year so far, previous highs being 9269 for June 22 and 9692 for July 13.

Note: warmer winter temperatures allowed mountain pine beetle populations to grow explosively through this region due to additional reproduction of adult beetles that were normally killed off by hard freezing winters. I did several Facebook posts in 2016 and 2018 on the increasing fire hazard this would create until the dead biomass was removed. This year’s extreme temperatures facilitated this!

At this point social collapse is inevitable…… We must stop and reverse the process of global warming that is causing this or face near-term extinction.

Antarctic sea-ice at ‘mind-blowing’ low alarms experts Excellent BBC article with good links to further research and discussions.

(13.09/2023) Nature Communications Earth & Environment. Record low Antarctic sea ice coverage indicates a new sea ice state.

In February 2023, Antarctic sea ice set a record minimum; there have now been three record-breaking low sea ice summers in seven years. Following the summer minimum, circumpolar Antarctic sea ice coverage remained exceptionally low during the autumn and winter advance, leading to the largest negative areal extent anomalies observed over the satellite era. Here, we show the confluence of Southern Ocean subsurface warming and record minima and suggest that ocean warming has played a role in pushing Antarctic sea ice into a new low-extent state. In addition, this new state exhibits different seasonal persistence characteristics, suggesting that the underlying processes controlling Antarctic sea ice coverage may have altered. [my emphasis]

Two change points are detected, separating the time series into three periods: November 1978 to August 2007 (grey), September 2007 to August 2016 (blue), and September 2016 to June 2023 (orange).

Storm Daniel comprehensively trashed several countries around the Eastern Mediterranean between 4 and 13 Sept.

Key facts from CDR (Center for Disaster Recovery):

  • As of Sept. 15, the Libyan Red Crescent said the death toll had reached 11,300 people in Derna alone. Officials expect this figure to continue to rise, possibly as high as 20,000. About 170 people were also killed in other parts of eastern Libya, including in Susa, Marj, Bayda and Um Razaz. More than 7,000 people were injured and at least 10,100 people are still reported to be missing. Because of the lack of telecommunications, some may be displaced and unable to reach family, but due to the large-scale destruction, it is hard to confirm these figures.
  • According to Floodlist, Libya’s National Center of Meteorology reported, “in a 24 hour period to Sept. 10, a staggering 414.1 mm [16.2 inches] of rain was recorded in Bayda, while 240 mm [9.5 inches] of rain fell in Marawah in the District of Jabal al Akhdar, and 170 mm [6.7] fell in Al Abraq in the Derna District.”

I used publicly available satellite imagery to try assess the damage attributed largely due to the failure of two dams. My conclusion is that the dams were no more than momentary and relatively insignificant barriers to to the flow of an inconceivably large volume of water. The following satellite images from Google Earth, and Sentinel Hub’s EO Browser clearly demonstrate the power of our planet’s increasingly extreme weather events driven by global warming. As the oceans and atmosphere warm, the atmosphere is able to transport increasingly stupendous volumes of water (in the form of water vapor) over the land to be dropped when the air cools for any reason.

The following image is what appears to be the center of the city of Derna (pop ~100,000) immediately before Storm Daniel dropped part of its load of water in the watershed of Wadi Derna. The very dry stream bed of Wadi Derna crosses the center of the image. If you have access to Google Earth, you can zoom in to see shadows of the few individual people out in the mid-day sun.

Zooming in, note the large building on the NE side of the Wadi 3 blocks downstream from the bridge on the lower left corner of the picture. It is a high-rise, where the tallest part is 9 stories above the ground floor, and the rest five. I determined the number of floor by counting the sun shades visible on the downstream side of the building. This is one of the few structures left in this part of town that can be identified in the next image.

Immediately after it looked like this:

Note the conspicuous high-rise (10 stories) easily marked by its long shadow in this image. The image below images this building from the down-stream side. The image here is relatively low resolution, but the three lowest floors (facing AWAY from the flood) have clearly been gutted by the flood. The bridge referred to in the previous picture has vanished leaving only two supports (aligned with the stream flow) to show where it was. Rows of 4-6 story buildings (and even some 8 story buildings just off the left edge of this image) extending 3-4 and even more rows back from the Wadi have totally vanished or are only memorialized by a bit of concrete slab or trace of a foundation wall.

The next two pictures zoom in on the area between the vanished bridge in the above images and the next bridge upstream (just off the edge of the above).

The three buildings to the left of the Wadi at the bottom of the image were respectively 7, 4, and 7 stories high

The next two pictures show the site of the lower dam – 250 meters upstream from the inland edge of the city.

Note: the dam has no spillway. Overflow protection is provided by the flared drain pipe (circular structure) in the lower left of the picture. Using Google Earth’s measuring tool, the diameter of the drain as approximately 6m. On the upstream side the surface of the reed bed is ~24 m above sea level, and the level of the road over the top is 45 m, giving the dam height of 21 m. On the downstream side the base of the dam is at 26 m, with the outlet for the overflow drain at approx 22 m. The length of the dam across the top is ~115 m, across the bottom (at reed level) is 50 m; thickness at the bottom is ~74 m, 8.5 m at the roadway.

The next Google Earth image is of the upper dam (12.5 km upstream from the lower dam) from immediately before Storm David’s rain. There is no high resolution image available from after the flood.

The drain tube (right side upstream) seems to be 7m in diameter. The dam is ~10 m high and 270 m long. 143 m thick at the base and 6.5 m thick at the top.

The last composite graphic gives an impression of the amount of water held behind both dams in the days immediately prior to Storm David. All are sourced via Sentinel Hub’s EO Browser and all are at the same scale – close to the maximum resolution available. The left four images are of the upper dam and its lake, while those on the right are of the lower dam and its lake. The upper three images of each dam use the Normalized Difference Moisture Index NDMI – that basically highlights any moisture in the otherwise barren landscape. The bottom picture is the same view as the one immediately above, except that it displays “true colors”. On the left in the top picture, on 10/01/2023 there was some water backed up behind the dam, perhaps 2 m deep at the dam wall given that most of the upstream face is still dry. The second picture, on 02/09/2023 shortly before Storm Daniel shows essentially zero moisture behind the dam, except there is a tiny blue streak in the bottom of the bright yellow area that is too small to be resolved at the magnification shown here. The blue areas below the dam are well watered orchards and fields – not standing water. The dam is visible in both of the above pictures. The third picture, from 12/09/2023 immediately after Storm Daniel shows the Wadi Derna has been scraped clean of any sign of a dam or the well watered agricultural area below the dam save the blue area off to the side. Inspection of the area just downstream from the pictures here in the before and after show the complete obliteration of farms and vegetation together with the road to a height of 20+ meters above the bottom of the wadi. A little further upstream – a bit closer to the dam, the landscape has been scraped up to a height of 38 m! above the wadi bottom, where the width of the wadi is approximately 200 m across. The height of this point is ~215 m above sea level (at least 10 m higher than the top of the dam!).

A similar story can be constructed for the pictures of the lower dam in the right column. The dams were minor inconveniences to the flow of the total volume of the storm water.

The Wadi Derna drains a large and relatively barren plateau with some of the weirdest landforms I have seen, and could possibly be organized so it receives large volumes of water from a number of subsidiary drainages at the same time. Or, more likely, the insanely hot Mediterranean air was supersaturated with water, and the storm dynamics led to rapid cooling that squeezed all of the water out over a very short period of time….. And the barren plateau lacked soil and vegetation to slow the flow of the water once it hit the ground, and simply demonstrated what can happen when the Earth System has too much energy to dissipate all at once in the form of climate catastrophes.

Consequently….

Our planet is progressively becoming uninhabitable!

G20: subsidizing fossil fuels and more global burning

G20 nations broke records in 2022 subsidizing fossil fuel: $1.4 TN in 2022 — more than twice what they have invested in sustainable energy.

Clearly, fossil fuel subsidies help the greedy special interests whose carbon emissions are smothering our planet drag us towards mass extinction from the ‘runaway greenhouse‘. Equally clearly, members of governments approving and providing these subsidies must be getting something in return.

Ajit Niranjan, 23/08/2023 in The Guardian

G20 poured more than $1tn into fossil fuel subsidies despite Cop26 pledges – report

Public money still flowing into industry despite agreement to phase out ‘inefficient’ subsidies, thinktank says

The G20 poured record levels of public money into fossil fuels last year despite having promised to reduce some of it, a report has found.

The amount of public money flowing into coal, oil and gas in 20 of the world’s biggest economies reached a record $1.4tn(£1.1tn) in 2022, according to the International Institute for Sustainable Development (IISD) thinktank, even though world leaders agreed to phase out “inefficient” fossil fuel subsidies at the Cop26 climate summit in Glasgow two years ago.

The report comes ahead of a meeting of G20 countries in Delhi next month that could set the tone for the next big climate conference, which takes place in the United Arab Emirates in November.

It is crucial that leaders put fossil fuel subsidies on the agenda, said Tara Laan, a senior associate with the IISD and lead author of the study. “These figures are a stark reminder of the massive amounts of public money G20 governments continue to pour into fossil fuels – despite the increasingly devastating impacts of climate change.”

Considering the world as a whole, the International Monetary Fund thinks that fossil fuel is subsidized by A LOT! more than $1tn.


Simon Black, Ian Parry, Nate Vernon, 24/08/2023 in IMF Blog

Fossil Fuel Subsidies Surged to Record $7 Trillion

Scaling back subsidies would reduce air pollution, generate revenue, and make a major contribution to slowing climate change.

Fossil-fuel subsidies surged to a record $7 trillion last year as governments supported consumers and businesses during the global spike in energy prices caused by Russia’s invasion of Ukraine and the economic recovery from the pandemic.

As the world struggles to restrict global warming to 1.5 degrees Celsius and parts of Asia, Europe and the United States swelter in extreme heat, subsidies for oil, coal and natural gas are costing the equivalent of 7.1 percent of global gross domestic product. That’s more than governments spend annually on education (4.3 percent of global income) and about two thirds of what they spend on healthcare (10.9 percent).

As the Chart of the Week shows, fossil-fuel subsidies rose by $2 trillion over the past two years as explicit subsidies (undercharging for supply costs) more than doubled to $1.3 trillion. That’s according to our new paper, which provides updated estimates across 170 countries of explicit and implicit subsidies (undercharging for environmental costs and forgone consumption taxes). Download detailed data for different countries and fuels here.

Read the complete article or follow links above.

The longer this evil cycle continues the less likely our escape from the dead-end road ending in Earth’s hothouse hell becomes. Seemingly, the only way we can find a side-road to a sustainable future is by replacing our present puppet governments with people committed to representing the interests of those who voted for them.

The only for them to know they will be replaced if they don’t do this is if for everyone who thinks this to tell their government representatives by post, email, phone, or old-fashioned knocking on the electoral office door. Only if enough people do this to convince special interest supporters that they really will be out of a job, will they begin to take the climate emergency seriously.

It is in your hands to start this action. VoteClimateOne.Org has the addresses and information you need to do this, and many other climate or energy action groups can also help you to power your tangible demands for action.

If you reference any of our evidence in your petitions to government member, they will know that a lot more people than you will be working to remove them from office if they don’t respond with serious climate action. See ACT NOW! and Traffic Light Voting.

Gov’t fiddling while Australia faces global burning

Labor Gov’t slashes vital Antarctic research by $25 M while promoting fossil fuel production/export and gifting $200 million to Aussie sport despite the desperate need to understand how unprecedented Antarctic ice and oceanic conditions relate to the climate crisis.

Anthony Albanese and the federal Labor government are supposedly concerned to keep Australians safe. Yet, if you listen to what they say,

  • It is necessary to save money by cutting $25 m from Antarctic research into why such a record shattering low amount of sea ice has formed this winter — a phenomenon that seems to place the whole of the human species at risk of near term extinction if we fail to understand and mitigate the risk. See what the science journal Nature says about this: (16 Aug 2923) Australia’s Antarctic budget cuts a ‘terrible blow for science’
  • It is more important to spend $200 m in voters’ tax dollars on cake and fairy floss (for girls sports) because the Matildas came 4th in the contest for the World Cup (see more below).
  • It is more important to cater to whims of fossil fuel with subsidies the Australia Institute estimates to be worth $57.1 bn over the forward estimates (see more below).
  • It is more important to grovel to America and the UK by spending $268bn to $368bn over the next ~30 years ($10 bn per year!) for delivery of 8 nuclear subs able to project our ‘power’ around the world in the by and by (the majority of these costs would also go overseas) when we could build 20 air-independent subs, a huge kit of other defensive weapons & related infrastructure, with $hundreds of billions left over (see more below).

I would call this government malfeasance of the highest order!

NO SINGLE POLITICAL PARTY SHOULD EVER AGAIN BE GIVEN THE MAJORITY POWER TO GOVERN FOR ITS OWN BENEFIT !

A couple of news items and some basic data on our only planet may make the claim of malfeasance more real.


Incredibly low sea-ice extent around Antarctica. Since early May (i.e., for more than 3½ months!) there has been an all-time record low for the month of the year since records began in 1979. Sigma (σ) is a measure of the probability of observing a deviation of that amount from the average of all measures for that day, assuming the deviations are randomly distributed. -5σ is about one chance in 3.5 million, -6σ is about one chance in 500 million! – and we have seen these extremes day after day after day!!

Vital research interrupted as Australian Antarctic Division faces budget woes

As many as 56 Antarctic research projects could be cancelled, delayed or restricted, said an email sent from the Australian Antarctic Division (AAD) to its staff.

The email stated that the division was facing budget constraints and would need to locate $25 million in savings in order to deliver the planned projects, which include studies into the diminishing sea ice, declining penguin populations, and the “cleaner Antarctica program”, an initiative designed to remedy damage caused by human activity such as oil spills.

Further information from anonymous insiders confirmed that two of Australia’s Antarctic research stations would not be fully staffed during the upcoming summer season, when scientific research at the south pole is usually at its peak.

The announcement comes at a crucial time for scientists, many of whom say this research is more important than ever.

Just last week, it was reported that Antarctic sea ice levels are at a record low, with ice that is normally recovered over the winter being absent – an event that would naturally occur only once every 7.5 million years. [this assumes that the variation is random, but clearly, this record is not random as the deviation has lasted for months, and many other climate indicators are also going crazy at the same time for similarly long periods]

“It couldn’t be any more catastrophic to hear at the moment, considering we’re seeing these incredible changes, particularly the sea ice right now. We’re seeing so little sea ice relative to what we normally see this time of year.”

If there’s a gap in data collection, it’s catastrophic for our understanding. If we have data up to a certain date, and then we have a gap for three years, five years, and then we start the data set again, it doesn’t make it useless. But it makes it really hard for us to get that understanding that we need.” [Especially when we need that information right now!]

Like most Australians, Prime Minister Anthony Albanese has been inspired by the Matildas’ World Cup performance Photograph: Mark Metcalfe/FIFA/Getty Images / From the article.

Albanese government to pledge $200m for women’s sport after Matildas inspire Australia

In the wake of the Matildas’ World Cup performance, the government will unveil new funding and changes to TV bidding rights for sporting fixtures.

The Albanese government will promise $200m to improve women’s sporting facilities and equipment after the Matildas’ historic Women’s World Cup run sparked an unprecedented outpouring of support for women’s football.

As the Matildas prepare for their third-place playoff against Sweden in Brisbane on Saturday, the government will declare the national team had “changed sport forever”, while unveiling a new funding package and flagging moves to make more major events available on free-to-air television.

The prime minister, Anthony Albanese, will announce a new grants program, called Play Our Way, with money available for all sports. The government expects soccer will need a significant amount, given clubs have seen a “mind-boggling increase in interest” in the wake of the World Cup.

The grant guidelines have not been completed, but the government said the money would go to “promote equal access, build more suitable facilities, and support grassroots initiatives to get women and girls to engage, stay, and participate in sport throughout their lives”.

[The total budget for the Antarctic Division is around $800 million…; The ANKUS Submarine Project will cost between $268bn to $368bn between now and the mid 2050s – assuming society doesn’t collapse from ‘global boiling’ and precipitate global mass extinction before then.]

Cumulative area burned in Canada by year estimated from satellite detected hotspots since measurements began in 2003. Natural Resources Canada. Black line is 2023. As at 23 Aug 2023 14,664,278 ha had burned (off the scale of the automatically generated chart) — 3 x larger area compared to the previous largest burn, 4,524,137, recorded for the whole of 2014. Note also that in previous years very little burning occurred after mid August. In other words 1.47 % of the total land area of Canada has burned so far this year, with no indication that the burning will be stopping any time soon.

Sea Ice Concentration: Where thin ice still exists, most of that is fairly broken up with 30% or more of the surface within the pixel apparently open water.

Sea Surface Temperature: Warmish sea water, 2-4+ °C comes up to the edge of the thin ice, and even seems to be detected within the edge of the mapped extent (>15% concentration)

Northern Hemisphere and Southern Hemisphere jet streams from ClimateReanalyzer’s Today’s Weather Maps. Normally each hemisphere has two circumferential jet streams: Polar and Sub Tropical. In the Northern Hemisphere the winds are mostly too slow to be considered as jet streams at all (> 60 kts) and essentially completely chaotic. This accounts for the frequent, long-lived, mostly motionless, and extreme heat domes promoting unprecedented flash droughts, wildfires, and floods. In the Southern Hemisphere, the winds are of jetstream strength, but again they seem somewhat confused and chaotic which may be associated with the extreme anomalies in sea ice.


What do these measures signify?

On its own, any one of the unprecedented deviations from ‘normal’ climate behavior over the last 40 years or more shown the the graphics above would be scary/remarkable. The fact that several different global measures are more or less simultaneously show similar degrees of (or even growing!) deviation over several months should be sounding emergency warning sirens around the world.

Reports posted to all Australian parliamentarians last month (available via VoteClimateOne.Org) provide more detail and explanation of these and other climate measures documenting the accelerating crisis: Cover Letter – 5 July 2023 and Australian MPs: Act Now! Later may be too late. These, in turn, link to still more recent data on Climate Sentinel News: Global Climate Change Now and an unedited collection of links to the latest news during August to date — Aug 2023 Climate extremes.

As explained, the nature, extent and duration of the deviations scream out that the complexly dynamical global climate system has been ‘forced’ by increasingly high global average temperatures out the semi-stable glacial-interglacial cycle where it is now beginning to fall (i.e., run away) towards climate apocalypse, collapse and global mass extinction in a much hotter ‘hothouse Earth’ state. The current rate of change in climate indicators is far faster than anything that can be reconstructed for even the worst of them all – the End Permian that also seemed to be driven by runaway warming as a consequence of greenhouse gas emissions. As explained in the documents cited in the previous paragraph, if we cannot mobilize effective action quickly enough to halt and reverse the global warming, our climate system seems to be crossing several tipping points that will drive us ever faster down the road to our extinction in Hothouse Hell. If we continue our present ‘business as usual’ attitudes of supporting the fossil fuel industry and gaslighting emergency actions to manage the climate crisis, and the climate trends seen in the last few months continue at the present pace, society may well collapse before 2050 with probable extinction of our species by 2100.

Note: In the cited documents above I suggested one of the tipping points being crossed was stoppage of Earth’s ‘thermohaline circulation‘ in the North Atlantic. At least I have found solid evidence showing that it is still working — even though hot water is covering the ocean surface — the depressed sea level and actual whirlpools E of Newfoundland and S of Greenland show deeper cool salty water is still being sucked down the usual plug-hole to the bottom of the ocean: last 30 days GIF of Sea Surface Height.


Is doom now inevitable or are there good reasons to think we can still climb out of the hole to a sustainable future? YES! Stainability is possible, but only if we act fast enough and hard enough!

Even if we have the threshold to runaway greenhouse, I remain optimistic enough to think if we act fast and hard enough we can still manage to find a survivable future. My reason is based on historical experience. I’m old enough to remember the atom bombing of Hiroshima and Nagasaki. Consider the history that led up to this:  It took something on the order of 150 years of work using steampunk technology starting with mining coal with picks and shovels to reach our current crisis point. However in the same 150 years our scientific understanding, technological prowess, and overall knowledge has grown exponentially over that same time with a doubling time of 2-5 years (see Homo habilis to Homo destructor ― How the rise of tool-making apes can destroy the world). 

America’s mobilization for WWII shows what humans can do in an emergency situation if they work together. Until Dec 7 1941 when Japan bombed Pearl Harbor, Americans were isolationist deniers of the reality of Axis aggression (not unlike Trumpist ‘MAGA’). By 8 May 1945 Germany had been expunged and on 6 Aug. 1945 the atomic bombing of Hiroshima (and then Nagasaki a few days later) overwhelmed Japan. In 1941 nuclear fission was a wacky idea proposed by some academics. In 4 years nuclear science was developed, the Manhattan Project was conceived, several different kinds of production infrastructure (Hanford, Oak Ridge Facility, Savanna River (a bit after the War), Los Alamos, etc…) were designed and built, atom bombs were designed, built, tested, and used. In the area of engineering and logistics, an average of 5 highly capable destroyers were built each month for 32 months and an average of 3 Liberty Ships every 2 days between 1941 and 1945. were able to be assembled and launched each week. The United Nations was formed, etc.. Equally prodigious challenges were met in many other areas that completely changed world history. Yes, conscription, coercion, rationing, etc. was required – but the global challenge was met and the common danger vanquished….

Today, we have massively more knowledge and prowess than we did in the early 1940’s. Humans can do remarkable things if people and governments unite and work together to fight the common danger. There is no greater danger than the near term extinction of our entire species and most of the rest of Earth’s biosphere!

In other words, there is no time left for the slow process of electing climate activists to replace sitting puppets in our parliaments.

We need a government fit and able enough to declare the emergency and lead an emergency mobilization to research and manage the climate crisis. If we are to gain effective government coordination and support we have no choice but to change the minds of the parliamentarians we have now.


Measuring Labor’s prioritization of the climate emergency relative to supporting the fossil fuel industry and crazy defence projects

A good measure of our government’s national priorities is the amount of our tax money being allocated to supporting various kinds of activities, and how these amounts change over time.

Australians are paying increasingly high costs due to more frequent, extensive, and severe weather and fire events associated with the accelerating rate of global warming driving climate change. One would think our government would give high priority to understanding what causes the extremes in hopes that we can better prepare for and/or mitigate the ever worsening catastrophes caused by the climate extremes. There are good reasons for thinking that positive feedbacks from ‘polar amplification‘ play a major role in driving the crescendo of climate catastrophes. This winter’s shockingly low rate of sea ice formation around Antarctica that might happen once in 500,000,000 (FIVE HUNDRED MILLION) years through random variation given the observed variations over the last 40 years. (Earth’s land animals emerged from the water less than 500 million years ago.) Clearly the missing winter sea ice is associated with the other similarly improbable climate extremes noted above for this year. Clearly we need to understand scientifically what has caused this year’s anomaly and how it relates to the other extreme variations…….. Yet, because the Government is cutting their funding, the Australian Antarctic “division [is] facing budget constraints and [needs] to locate $25 million in savings in order to deliver the planned projects, which include studies into the diminishing sea ice, …”, etc. Clearly, our government has little interest in supporting Antarctic research critical for understanding climate change.


Some indication of who our Australian state and federal governments are supporting big-time (along with many other countries) is their apparent patrons in the fossil fuel industry (mostly comprised of overseas multinational companies).

By comparison, it is interesting to see how concerned Federal Labor is to support action to protect citizens from the increasing catastrophic and existential threats from climate climate change driven by global warming.

According to the numbers the Climate Council has provided, their steps towards climate action amount to $3,621,600,000 for some very fuzzily defined categories — $3.62 bn compared to $29 – $57 bn (depending on who you follow) in pretty definite subsidies and supports for the mostly overseas fossil fuel industry.

What do they get in return for this money? In FY2022 [1], fossil fuel companies donated $2 million to the ALP, Liberal and National parties. Not a lot, but it helps them with ‘winning the election’ costs. Total revenue from the industry is around $20 bn (still less than the subsidies!)


And then there is government management of the potentially existential cost of the climate emergency versus abject kowtowing to ‘his master’s voice’ via AUKUS

Rex Patrick, ex submariner in Oberon and Collins Class subs, sonar and electronic technologies expert, defence contractor, author for the Australian Strategic Policy Institute, and Federal Senator from South Australia, is what I would consider to be a qualified expert on naval technology. In one X-tweet Mr Patrick demonstrates just how mindlessly stupid allocating $368 bn to AUKUS would be — even for the purpose of acquiring military kit to defend ourselves from other nations:

Instead of 8 nuclear subs that may (or may not) be delivered for the currently estimated cost sometime by the Americans and UK able to project Australian power (for whose benefit?) to the other side of the planet, the same budget would supply 20 air-independent (= very quiet!) subs to protect Australian interests around our shores and in adjacent waters (e.g., Indonesian Archipelago) and a huge kit of additional defence hardware that could mostly be manufactured within the Australian economy — leaving $200 BILLION FOR MEASURES TO KEEP AUSTRALIANS SAFE FROM CLIMATE CATASTROPHE.

What is it about Australian governments in majority power that makes them so eager to work for the interests of (mostly overseas) special interest patrons rather than for the safety and well-being of Australian citizens who have voted to put them in power? To reiterate:

We need a government fit and able enough to declare the emergency and lead an emergency mobilization to research and manage the climate crisis. If we are to gain effective government coordination and support we have no choice but to change the minds of the parliamentarians we have now.

The only way this will happen is if they can be convinced that voters will remove them from Parliament at the earliest possible opportunity if the don’t. They only way they will be convinced they will be voted out is if enough voters flood their mail boxes, in trays, and phone lines with demands for climate action — or else! And, I’m pretty sure there are enough members of climate and environment action groups that if we all sent our emails, posts, phone calls, and even personal visits to electoral offices to deliver this message, that action will be taken.

Hawaii Officials Release List of 388 People Missing From Maui Fires. New York Times 25 Aug 2023

Authorities in Hawaii released a list late on Thursday naming 388 people who are still unaccounted for in the aftermath of the deadliest wildfires in America in more than a century, which killed at least 115 people.

The fires devastated the coastal town of Lahaina on the island of Maui, as well as other areas of the island, more than two weeks ago. Search-and-rescue teams are still sifting through the last patches of ash and rubble looking for human remains.

In publicizing the names, the authorities hope to narrow the tally of the missing. In a statement, Maui’s police chief, John Pelletier, asked anyone who survived the fire to come forward and remove their name from the list. Officials had said earlier on Tuesday that 1,000 to 1,100 people remained unaccounted for.

The list released on Thursday, Mr. Pelletier said, includes anyone for whom officials have a first and last name and contact information for the person who reported them missing.

Officials have been bracing the public for the likelihood that the number of confirmed dead from the fires — which stands at 115 — will rise substantially.

Australia’s Antarctic budget cuts a ‘terrible blow for science’ Scientists around the globe have expressed concern at reports that the Australian Antarctic Division will have its budget slashed by the government. Nature 16/08/2023

Scientists worldwide fear that research tracking how climate change is affecting Antarctica will be disrupted, after it was reported that the Australian Antarctic Division (AAD) will cancel, postpone or strip back several of its research projects this summer because of a looming Aus$25-million (US$16.2-million) budget cut. The cut comes hot on the heels of the news that Antarctica’s sea ice has hit a drastic and surprising new low.

Among the projects on the chopping block are studies investigating how sea ice is changing in the warming climate. “It’s just a terrible blow for the science,” says Nerilie Abram, a palaeoclimate scientist at the Australian National University in Canberra who chairs the Australian Academy of Science’s National Committee for Antarctic Research.

In July, AAD management told staff by e-mail that it needed to reduce its annual operating budget for the next year by 16%. AAD staff have confirmed to Nature that several projects scheduled to be conducted from Davis and Mawson will not be supported this season, including surveys on sea-ice thickness and landfast sea ice — large ice sheets that are ‘fastened’ to the shoreline or sea floor.

Nathan Bindoff, a physical oceanographer at the University of Tasmania in Hobart, Australia, says he was “astonished” when he learnt about the cuts. “That’s a lot of money — even in a very big programme — to absorb,” says Bindoff, who leads the Australian Antarctic Program Partnership, which collaborates with the AAD to understand the role Antarctica has in the global climate system and the implications of this relationship on marine ecosystems.

On 27 June, data from the US National Snow and Ice Data Center showed that the sea ice surrounding Antarctica had reached a record low winter extent of 11.7 million square kilometres, more than 2.5 million square kilometres below the average for the same time of year between 1981 and 2010. Although researchers expect sea ice to dwindle as climate change intensifies, its drastic fall this year came as a surprise, says Abram.

Now, more than ever, researchers need to be on the ground in Antarctica to gain a better understanding of what’s driving the sudden decline in sea ice, she says. “We really need to get there to make those physical measurements.” Abram adds that gaps in long-term monitoring data will make it difficult for researchers to understand how Antarctic systems are changing as temperatures rise, particularly on the relatively understudied eastern side of the continent, where the Australian division is based.

Atmospheric Methane: Comparison Between Methane’s Record in 2006–2022 and During Glacial Terminations – https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2023GB007875

Atmospheric methane’s rapid growth from late 2006 is unprecedented in the observational record. Assessment of atmospheric methane data attributes a large fraction of this atmospheric growth to increased natural emissions over the tropics, which appear to be responding to changes in anthropogenic climate forcing. Isotopically lighter measurements of

urn:x-wiley:08866236:media:gbc21450:gbc21450-math-0001

are consistent with the recent atmospheric methane growth being mainly driven by an increase in emissions from microbial sources, particularly wetlands. The global methane budget is currently in disequilibrium and new inputs are as yet poorly quantified. Although microbial emissions from agriculture and waste sources have increased between 2006 and 2022 by perhaps 35 Tg/yr, with wide uncertainty, approximately another 35–45 Tg/yr of the recent net growth in methane emissions may have been driven by natural biogenic processes, especially wetland feedbacks to climate change. A model comparison shows that recent changes may be comparable or greater in scale and speed than methane’s growth and isotopic shift during past glacial/interglacial termination events. It remains possible that methane’s current growth is within the range of Holocene variability, but it is also possible that methane’s recent growth and isotopic shift may indicate a large-scale reorganization of the natural climate and biosphere is under way.

I think humans have reached the point where we have to unite to mobilize a global war against global warming or accept near-term human extinction. Just from today’s evidence there are strong reasons to think we have gone over the threshold of a cascade of tipping points into temperature raising positive feedbacks that seem to have no off switches — and we are still doing our best to continue increasing the concentrations of greenhouse gases.

SSS = Sea Surface Salinity. Here you can clearly see relatively fresh cold water flowing out into the North Atlantic east of Labrador making saltier water less dense (that is already too hot and light to sink into the depths to drive the deep water return flow of the AMOC / Atlantic Conveyor / Atlantic branch of the global thermohaline circulation work. In other words there is currently a total stoppage of the AMOC. Southern branches also seem to be mostly plugged judging by the water around Antarctica being too hot for anything like normal amounts of Antarctic sea ice to form in the southern winter.
Mixed layer depth. Note that vertically insolated regions (northern hemisphere summer) have very shallow mixed layer. Antarctic subpolar regions with little or no solar heating have deep mixed layers (i.e., with little thermal stratification) presumably facilitating the formation of sinks for cold mixed water into the global thermohaline circulation.

Global Climate Change Now

25/07/2023 (for the last version see 8/07/2023)

What’s this article about, and why is the date important?

As I write this, the average climate for our WHOLE PLANET is changing so freaking fast we can see visibly measurable changes in the averages from one day to the next!

The sudden speed up of changes in several climate indicators at the same time suggests that we may be crossing a critical tipping point in the complex interactions of important temperature related feedbacks controlling the behavior of Earth’s Climate System, as shown in the Featured Image. The speed-up is highlighted by the fact that the average air temperature 2 meters above the surface of our planet is at an all time record (and especially in the satellite era beginning in 1979). These changes will affect the whole 8,000,000,000+ humans and alive today along with all other life on the planet. The charts and maps presented here graphically illustrate measurements of important climate variables up to the last 1 to 4 days.

Fig. 1. ClimateReanalyzer’s Time Series plotting of Earth’s global average temperature at 2 meters above the surface from the NCEP Climate Forecast System (CFS) version 2 (April 2011 – present) and CFS Reanalysis (January 1979 – March 2011). CFS/CFSR is a numerical climate/weather modeling framework that ingests surface, radiosonde, and satellite observations to estimate the state of the atmosphere at hourly time resolution onward from 1 January 1979. The horizontal gridcell resolution is 0.5°x0.5° (~ 55km at 45°N). The time series chart displays area-weighted means for the selected domain. For example, if World is selected, then each daily temperature value on the chart represents the average of all gridcells 90°S–90°N, 0–360°E and accounts for the convergence of longitudes at the poles.

Again, every day since July 3 has been hotter than any maximum temperature recorded for any prior year back to 1979 when these records were compiled.

@EliotJacobson on Twitter shows this data a bit more legibly. The first record high was on 3 July, and daily average temperatures have remained in annual record high regions for a total of 12 ! continuous days through 14 July. The record is now 21 days!

The time gap between the instants of measurement depicted in the plots and charts and when they were printed are due to time delays between:

  • automatically recording millions of readings from hundreds of thousands of networked physical sensors and more millions of readings from remote sensors on a plethora of artificial satellites whizzing around our revolving planet several times a day (“Intensity of observation”, below, illustrates just how comprehensive the sensor network is);
  • accumulating and assembling the recorded data over the world-wide communications network;
  • proofing, processing and tabulating the received data on the world’s largest supercomputers; reanalyzing and plotting the observations in the form of charts and graphs comprehensible to humans;
  • publishing and publishing these outputs onto the public web, where they are accessible to anyone with a computer and the knowledge to find and understand the representations.

Based on the most recent measurements, the ongoing climate changes are accelerating in directions and speeds that will inevitably be lethal to the human and many other species within another century, more or less, if the changes are not stopped and reversed. These changes are a direct consequence of an unplanned experiment that humans began around 1½ centuries ago to burn geologically significant quantities of fossil carbon (e.g., coal, oil, ‘natural’ gas) into usable energy and greenhouse gases trapping an ever growing proportion of the total solar energy striking Planet Earth.

However, some of the combustion energy released by burning fossil carbon has also fueled an exponential growth of knowledge and technology able to produce the I am showing here. These plots provide the evidence our experiment is changing our global climate system to a state that will have existentially catastrophic consequences for Earth’s complex forms of life. This Hellish state is known as “Hothouse Earth“.

This fact that we now have the tools to actually see the evidence of our likely doom gives me some hope that our still exponentially improving technology may also provide us with the ability to stop further damage caused by our rogue experiment and repair enough of the damage already caused, to allow our species to continue evolving into the foreseeable future.

This raises the unavoidable and fraught question: Do we humans have the political will and capability to marshal and mobilize our technologies to engineer solutions that will allow us to avoid the abyss? This is the single most important issue facing the world today. If we don’t solve it, no other issue matters because — before long — no one will be left to worry about it.

Problematically, the world’s governments are dominated by puppets of the fossil fuel industry and related interests. They are doing as much as they can to PREVENT, DELAY, or MINIMIZE any actions that might hamper fossil fuel’s greed and short term interests for the world to burn yet more fuel. Hoping that we humans can solve this single, most important issue, VoteClimateOne is working to revolutionize our governments by replacing or changing parliamentary puppets to prioritize actions to solve the climate crisis first. Also, I am writing articles such as this to demonstrate and explain why this revolution is so urgent and necessary.

To demonstrate just how rapidly we are currently moving down the road to doom in what will be Earth’s Hothouse Hell, this article will be updated at least once a week until there is evidence of a downward trend to safer readings. We are certainly not seeing them yet!

Measuring progress towards existential catastrophe on Hothouse Earth

The world’s polar regions are critical. Ice and snow covering land and ocean reflects around 90% of the solar energy striking it. As temperature rises, more of the frozen water melts, allowing the exposed earth and water to absorb a much greater proportion of the solar energy during 24 hour-long polar polar daylight (open ocean absorbs ~94% of the energy striking it) , causing polar and global temperatures to rise in a potentially accelerating feedback cycle. In the animated graphic below, this process is clearly visible since the mid 1930s. This particular cycle won’t be broken until the ice is essentially all melted. By then there are several other feedbacks that will likely be in full swing.

Fig. 3. Zonal-mean (averaged over longitude) temperature anomalies for each year from 1900 to 2022. The x-axis is latitude (not scaled by distance), and the y-axis is the temperature anomaly. Data is from Berkeley Earth Surface Temperatures (BEST; http://berkeleyearth.org/data/) using a reference period of 1951-1980. (Zachary Labe 2023. Climate Indicators.

Ocean measurements are critical

Because most humans live on continental land masses, immersed in the atmosphere, most climatologists are primarily concerned with what goes on in the atmosphere. However, because water covers some 70% of our planet’s surface and because of water’s physical properties, around 90% of the excess solar energy striking Earth is absorbed in the World Ocean. Heat is then transported around the planet in currents and is available to be released to drive climate. See below for explanations of how the major heat engines driving Earth’s Climate System interact and work.

Fig. 4. Growing heat content held by our warming Ocean Current to Feb. 2023 (NOAA data)

Because these climate ‘engines’ are complex dynamical systems with many interacting components, where the interactions are often non-linear and sometimes even chaotic (in a mathematical sense their behavior is inherently unpredictable to any statistically define degree. Positive feedbacks in such systems can be potentially destructive because they lead to exponentially growing changes that lead to system breakdown (because infinity is impossible in the real world). Mathematical modeling of the interactions of small sets of variables can provide an appreciation of how such breakdowns may occur. Systems engineering as practiced in large defence engineering projects is based around a MilStd known as Failure Modes Effects and Criticality Analysis (FMECA) to identify such kinds of failure modes in order to engineer system solutions mitigate or totally avoid circumstances where they might arise.

The charts and maps below show how some measures of the behavior of Global Climate System have been behaving over the last few months and days. I consider these to be critical because they are likely to be evolved in the kinds of positive feedbacks that can grow exponentially to cause systems failure or collapse.

A definition

Many of the charts represent values of particular variables averaged over the surface of the whole Earth (or some specified region) at a specified point or interval of time. Most maps use colors to indicate the value of a specified variable at a specified point or averaged over an interval of time. In most such cases these measures are presented in the form of “anomalies”. An anomaly is the difference between the particular measurement and the long-term ‘baseline’ average for that measure on that day or interval of the year. For example, the graph immediately below uses a 30 year average (from 1971-2000) for its baseline average. Anomaly plots are particularly useful to highlight changes taking place over time.

Critical Variables

Global Sea-Surface Temperature

The global sea surface temperature anomaly broke into all-time record for the day of the year around 15 March, and by the end of March it was an all time record high since 1981, 0.1 °C above the previous record set on 6 March 2015. This value is so extreme, that along with other variables noted below it suggests that the average rate of global warming observed over the last few decades may be shifting into a new regime where the rate of ocean-surface warming is skyrocketing. As at 29 June it is still 0.2 °C above the previous record for that date – with an uptick after 4 days of downward trend).

Fig. 5a. Time series visualizations of daily mean Sea Surface Temperature (SST) up to 23 July. Data from NOAA Optimum Interpolation SST (OISST) version 2.1. OISST is a 0.25°x0.25° gridded dataset that provides estimates of temperature based on a blend of satellite, ship, and buoy observations. The datset spans 1 January 1982 to present with a 1 to 2-day lag from the current day. Data are preliminary for about two weeks until a finalized product is posted by NOAA. This status is identified on the maps by “[preliminary]” appearing in the title, and applies to the time series as well. SST anomalies, which are included in the OISST dataset, are based on 1971–2000 climatology. The time series chart displays area-weighted means for the selected domain. For example, if World 60S-60N is selected, then each daily SST value on the chart represents the average of all ocean gridcells between 60°S and 60°N across all longitudes, and accounts for the convergence of longitudes at the poles.

The North Atlantic’s fever is still has a fever is still growing on 13 July. Warmer than usual water flooding up around southern Greenland right up to the edge of the melting sea-ice, with what looks like cold fresh meltwater flowing out of Baffin Bay along the west side.

Note that the ocean surface temperature is 5 °C right up to the edge of the sea ice, with warmer water than that intruding nearly as far as the ice front in Baffin Bay. The cooler (purple shaded) water flowing down close to the Canadian shoreline has been pushed back into Baffin Bay (between Greenland and Canada. There is no sign in either of the SST maps of ‘cool spots’ which are thought to be the sources of the ‘salty cold water’ forming the deep water branches of the thermohaline circulation in the North Atlantic. In fact, the ocean in these areas seems to be 10-15 °C. Northern Hemisphere ice extents are low for the date but not yet near record lows, unlike the South!

Global Sea Ice

Antarctic Sea ice

Around the same time the global average sea-surface temperature began to skyrocket, the rate of sea-ice formation around Antarctica slowed — as would be expected if the surrounding ocean was becoming progressively warmer than has ever before been the case for this time of the year.

Sea ice extent anomaly is strongest in the Weddell and Bellingshausen Sea region. With the Indian Ocean region also showing what looks like the beginning of a strong deviation. The illustration is from the article from the Australian Antarctic Program Partnership that discusses the significance of the anomaly.

Note deep red is -70%, and lack of sea ice in Bellingshausen Sea (west of Antarctic Peninsula). Even though Antarctica is in mid-freeze season, Bellingshausen Sea is almost at summer sea-ice levels. (Source: interactive chart accessed at nilas.org). see also Polar View.

Sea ice extent anomaly is strongest in the Weddell Sea (area above the Antarctic Peninsula) and Bellingshausen Sea region (indicated by the arrow above). With the Indian Ocean region also showing what looks like the beginning of a strong deviation. See especially the article from the Australian Antarctic Program Partnership that discusses the significance of the anomaly.

This graphic from NASA Earth Science’s Current State of Sea Ice Cover shows the slow rate of ice formation around Antarctica. The almost complete absence of ice in the Bellingshausen Sea is remarkable. It is only now in the last few days that it is beginning to ice over. There is also significant open water within the extent of the sea ice.

Arctic Sea Ice

So far, melting of the Arctic sea ice has not been particularly exceptional. With regard to sea-ice at both poles, it is also important to consider thickness and volume. Ice that is only a meter or two thick is accumulated over winter when there is no solar heating (sun largely or completely below the horizon) is normally only a year old. Solid ice reflects most of the solar energy heating it. However, the thinner the ice is, the faster it can melt as it begins to heat under the summer sun and possibly even rain(!), to say nothing of warm currents from the tropics. Around the North Pole, all of the bluish and purple ice shown in the map here can disappear fairly quickly as summer continues to leave open ocean to absorb most of the solar energy striking it that will delay freezing in the following winter.

Fig. 11. Thickness of Arctic Sea Ice for the month of July 2023. This is an animated reanalysis and forecast system developed by the US Naval Research Labs, based on the global database. It is one of several oceanographic data plotting visualizations for the Arctic (see System information). Presumably in the light lavender areas the remaining ice could disappear in a few days of warm temperatures.
See also Danish Arctic Research Institution’s Polar Portal for current info on the northern polar region.

Arctic sea ice beginning to thin and break up as far as the North Pole. Shades of blue within the ice cap show regions where less than 100 percent of the quadrangle are covered by ice. (Either due to exposed ocean water or puddles of rain/melt-water on top of the ice). In either case this is bad news for reflectivity of the ice cap.

Atmosphere and land

Jet streams

Fig. 13a. Jet streams in the Southern Hemisphere.
Fig. 13b. Jet streams in the Northern Hemisphere
Fig. 13c. Global distribution of jet streams.

Jet streams are the atmospheric equivalents to major ocean currents that influence all of the other weather systems on the planet to keep them moving latitudinally around the planet. They are driven by temperature differences between the tropical and polar regions of the Earth and Coreolus effects as winds blow towards or away from the poles. Where the temperature differs strongly between poles and equator the jet streams are well organized with high winds. As temperature differences decrease so do the wind speeds, and the streams begin to slowly meander until they may become quite chaotic. Winds less than 60 kt are not considered to be jet streams. At present there has been very little change in the pattern that existed a week and a half ago (as shown in Fig 8b) there are virtually NO jet streams at all in the Northern Hemisphere, and the winds that do exist are completely chaotic — a highly unusual situation. This leaves major heat domes basically motionless, facilitating the buildup and maintenance of record high temperatures.

See: Nature Climate Change, Lenton (2011) Early warning of climate tipping points.

Continental effects

Fig. 14. The taiga biome is found throughout the high northern latitudes, between the tundra and the temperate forest, from about 50°N to 70°N, but with considerable regional variation. (Wikipedia).

Some of the greatest impacts of the disrupted jet stream system are seen over the boreal/taiga forest zones of North America and Eurasia. Arctic tundra and much of the taiga is underlain by carbon rich peat and peaty permafrost soils that are thought to contain at least 2x more carbon than the current amount of carbon in our atmosphere. Depending on circumstances, significant amounts of that carbon can be released in the form of methane, that has more than 80x the greenhouse potential of CO2 over the first 20 years of emission (20x over 100 years). Aside from greenhouse gases emitted by the burning forests and soils, significant amounts of the black carbon ‘ash’ will settle on Arctic snow and ice – speeding their melting when exposed to sunlight. Collectively, at least over the first few years following wildfire, the burning will provide yet another powerful positive feedback to speed snow and ice melting. Over a longer term, re-vegetation will sequester some atmospheric CO2, but only if the forest is not burned again.

Fig. 15. By the end of June Canadian wildfires mainly in boreal forests have burned more area before the fire season is half over than in the previous record for a full year in 1989. Phys Org (30 June 2023). As at 24 July 11,582,531 ha have burned. The graph here, sourced from Natural Resources Canada gives the status as at 15 July. This is literally ‘off the chart’, and represents about 1.1% of Canada’s total land area.

Wildfires not only release the carbon contained in burned forests and tundra, but they can also burn the carbon rich peat soils. furthermore, burning off insulating vegetation and surface litter exposes permafrost to melting and release of CO2 and methane from frozen hydrates.

If the burning releases more greenhouse emissions than can readily be recaptured by re-vegetating forests. These emissions may more than replace any emissions humans cut — providing positive feedback to drive global temperatures still higher. This is one of several crucial tipping points associated with stopping the thermohaline circulation.


Intensity of observation

A hint to how little you can trust claims of reality denying trolls, puppets, and the like, is provided by the number monitoring points that physically monitor the atmosphere at those locations around the surface of the planet we live on used PER DAY.

Atmospheric monitoring

The European Centre for Medium-Range Weather Forecasts (ECMWF) for the charts plotted on 6 July 2023 as shown below are based on measurements from 92,702 locations. Note 1: this map does not NOT include ocean monitoring points. Note 2: The DATA COLLECTED EVERY DAY by this web of sensors is available to, used, and interpreted by several different national and institutional climate monitoring centers. In other words, the conclusions are cross checked between different centers many times over. The charts above depict scientific facts, not hunches and personal opinions. For more detail on how the accuracy of the observations is controlled see ECMWF’s Monitoring of the observing system.

Fig. 19. The type and location of 92,702 separate observations used on 6 July 2023 between 3:00 and 9:00 PM for 6 hourly data coverage used by the ECMWF data assimilation system (4DVAR). Each plot shows the available data for a family of observations. The current day’s chart can be downloaded here. SYNOP refers to encoded information collected and transmitted every 6 hours by more than 7600 manned and unmanned meteorological stations and more than 2500 mobile stations around the world and is used for weather forecasting and climatic statistics. SHIP METAR is a format for reporting weather information. A METAR weather report is predominantly used by aircraft pilots, and by meteorologists, who use aggregated METAR information to assist in weather forecasting.

Oceanographic monitoring

Argo

Argo floats profiles physical properties of the surrounding water, minimally ocean temperature, salinity, pressure (i.e., depth). Each float operates on a 10 day cycle, spending most of the cycle ‘resting’ at an intermediate depth. On the 10th day it sinks to a specified depth and begins recording inputs from its sensors as it floats up to the surface. The standard float sinks to a depth of 2 km (2,000 m) and records all the way up to the surface, where it then determines its GPS position to within a few meters and messages a passing relay satellite with its location and profile data before sinking to its resting depth waiting for the next profile position. As shown on the world map here, for June 2023, shows the locations of 3849 profiles received over the month. Of these ~1,400 recorded the profile from 2 km deep in the ocean to the surface. Some floats are designed to sink to the bottom and thus record a profile for the full depth of the ocean. A few include several additional sensors to levels for things like acidity, oxygen, nitrate, light level, and some more I don’t recognize. The Argo system is really quite amazing.

Some even have ice sensors allowing them to operate even in ice-covered waters by warning if they might be fatally damaged by striking ice overhead. For these, if they sense ice, they’ll record the profile in memory, and drop back and rest until the next cycle (which may again prevent surfacing). These interrupted cycles will keep repeating until the float can safely surface — in which case all of the aborted profiles will be messaged to the satellite relay along with the current one (better late than never!)

Fig. 20. Argo floats operational in June 2023. For the latest data see Ocean Ops dashboard

And then there is a plethora of other ocean sensor systems. The full gamut of them shown next. The various different types are named in the legend. Collectively, on 26 June 2023, the ocean sensing system measuring in-situ variables includes 7973 ‘platforms’ (including the different kinds of Argo Floats) and results from 104 ‘cruises’ of ships ranging from specialized oceanographic vessels to fishing boats. Some of these non-Argo systems also record partial or complete (i.e., to the bottom) profiles.

Almost all of the data collected from the range of sensors is freely accessible via the public World Wide Web.

Fig. 21. Location of ocean sensor platforms.

Satellite remote sensing systems

As if the plethora of physical systems for directly measuring weather and climate is not enough. There is now a cloud of satellite-based remote sensing systems buzzing around our planet, making literally millions of observations every day of critical weather and climate variables. NASA EarthData’s What is remote sensing? gives a high level overview of some of the capabilities of these systems. You can be assured that the measurements made by the earth-based and space-based sensing systems are carefully cross calibrated to ensure the various systems are all working together towards a common view of the actual physical reality.


Major heat engine domains of the Earth System

Dynamic changes in the Universe through time are driven by spontaneous flows and transformations of energy from ‘sources’ at high potential to entropy and ‘sinks’ at lower potentials (e.g., water flowing down a hill). This flux can be used to drive other processes through a system of coupled interactions forming a thermodynamic system or heat engine. As governed by the universal physical Laws of Thermodynamics (especially the Second Law), as long as there is a potential difference between source and sink, the flux of energy between them will continue to spontaneously flow through the system/heat engine as long as long as the system’s net entropy production remains positive.

The ‘Earth System’ includes all the shell-like layered components of the planet from the edge of outer space to its center. The three main ones concerning us here from inside out are the geosphere, hydrosphere, and atmosphere. The biosphere formed in the interface between atmosphere and geosphere (on the planetary scale) is a microscopically thin turbulent layer of carbonaceous macromolecules and water combined with other elements and molecules exhibiting the properties of life. We humans form part of that biosphere.

The heat engines described here circulate masses of matter that transport heat energy from place to place within the Earth System.

Geosphere

The geosphere comprises Planet Earth’s, solid (‘rocky’) components. The geosphere’s heat engine is based on the geologically slow process of plate tectonics that drives continental drift.

Fig. 22. Geological heat engine at work. Mantle convection may be the main driver behind plate tectonics. Image via University of Sydney.

The plate tectonics engine is driven by the slow radioactive decay of unstable isotopes of elements such as potassium, uranium and thorium remaining from the formation of Earth some 4.5 billion years ago.

Enough heat has and is being generated by this decay to melt the planet’s core and heat and expand the overlying mantle rocks enough to make them less dense and plastic enough for them to form convection cells like you see in a pan of nearly boiling water. Hotter and less dense rocks float up towards Earth’s harder crust and spread out (carrying surface crust and even lighter continental rocks, i.e., ‘plates’) to become cool enough for gravitational force to pull the solidified plates back towards the molten core in subduction zones that also form oceanic trenches.

Heat transported from radioactive decay is released into the hydrosphere and atmosphere from conduction through the crust + hot springs and geysers; by molten basalt lava coming to the surface in oceanic and terrestrial spreading (‘rift zones’); and volcanoes associated with localized ‘hot spots of rising magma or with the rift zones. Lavas associated with the latter type of volcanoes are formed of lighter, lower melting point rocks forming a scum on top of the denser crustal rocks of the drifting plates.

Hydrosphere

This image has an empty alt attribute; its file name is Thermohaline_circulation.svg

Earth’s hydrosphere is the thin film of water between the geosphere and atmosphere forming the salty Ocean covering around 70% of the planetary surface along with lakes and streams of generally nearly salt-free water serving as feeding tendrils draining water condensed from the land. The hydrosphere also includes a solid component of ice and a gaseous component of vapor. These components have very different properties compared to water and each other.

The liquid component of the hydrospheric heat engine absorbs solar energy in the form of heat warming volumes of water, in the form of latent heat of fusion (i.e., melting of ice) absorbing about 80 cal/gm of ice melted, and latent of vaporization (i.e., turning liquid water into an atmospheric gas) absorbing about 540 cal/gm of water vaporized (6.75 times as much energy as required to melt the gm of ice). The heat absorbed becomes ‘latent’ in that the energy transforms the state from liquid to solid or from liquid to gas without changing the measurable or feel-able (i.e., ‘sensible’) temperature of the mass. When the water vapor condenses or the water freezes, of course the latent energies are released in the form of sensible heat.

Basically, the hydrospheric heat engine is driven by the absorption of excess amounts solar radiation (the source) in equatorial, tropical, and subtropical regions of the planet that is mainly carried by ocean currents towards the polar and sub-polar regions where the an excess of heat energy released from water and freezing ice is carried away from the planet in the form of long-wave infrared radiation to the cold sink of outer space. Many different local, regional, and global ocean currents are involved in moving energy around the planetary sphere. Proportionately, a small amount of geothermal heat energy is absorbed from the geospheric heat engine by water, and larger amounts of heat are exchanged with the atmospheric heat engine(s) in a variety of ways.

Water has some very peculiar properties that play very important roles in the climate system and biospheric systems, especially around the freezing point. Most materials contract and become denser as they cool. This is also true for pure water, down to a temperature of 4 °C when it begins to expand and become less dense until it begins to freeze. Ice at 0°C is even lighter such that it easily floats. This is because water molecules are shaped like boomerangs with the oxygen atom at the apex and the two hydrogen atoms sticking out at angles. When they are warmer they jitter around in a relatively random way, such that warming makes the molecules jitter faster and further, while as they cool the jitter slows and they come closer such that a given number of molecules take up less space. As the jitter slows further at and below 4 °C, molecules tend to spread out some to form a quasi crystalline structure approaching that of ice where they are more or less locked into that structure, where the solid water is significantly lighter than the liquid. The presence of dissolved salts and minerals depresses the freezing temperature. As as ice freezes, crystallization of the water also tends to concentrate and expel dissolved minerals and gases in extra-cold plumes of particularly dense and very cold salty water (i.e., brine) — cold enough that tubes of ice may form from the less salty water around the brine.

Water is also a god solvent, able to carry substantial amounts of gases, (e.g., oxygen, CO2, methane – CH4), salts, carbonates, nitrates, sulfates, metal ions, etc). The ocean carries a lot of salt – enough to play an important role in the ocean circulation system. Oxygen and CO2 play essential roles in living systems, CO2 and carbonates play important roles in interactions between water, the Geosphere and the atmosphere. CO2 and methane in the atmosphere, along with water vapor, are the most important greenhouse gases, etc…..

Fig. 23. A summary of the path of the thermohaline circulation. Blue paths represent deep-water currents, while red paths represent surface currents. This map shows the pattern of thermohaline circulation also known as “meridional overturning circulation”. This collection of currents is responsible for the large-scale exchange of water masses in the ocean, including providing oxygen to the deep ocean. The entire circulation pattern takes ~2000 year. Wikipedia

The principal current system driving ocean heat transport is known as the ‘thermohaline circulation‘. Basically, seawater is warmed in the equatorial, tropical and subtropical regions of the world. It also increases in density due to the evaporation of water vapor into the atmosphere. However, parcels of water are kept hot enough that thermal expansion more than compensates for the densification from becoming saltier. However, as currents carry the hot, salty surface water further towards the poles, the water begins to cool until the warm salty water carrying a full load of oxygen becomes dense enough around 4 °C to sink through layers of still warmish but less salty water, carrying a full load of oxygen down to the bottom of the ocean. The salt in this descending water is diluted by mixing with relatively fresh ice water from terrestrial runoffs, melting glacial and sea ice, etc sourced from zones even closer to the poles than where the dense salty water normally sinks.

The main source of power that drives the thermohaline circulation heat engine is the conversion gravitational potential energy in the sinking masses of water as they sink to the ocean floor this sinking helps to pull surface waters into the ‘sinkhole’. Further assists to the circulation are provided by prevailing atmospheric winds pushing surface waters away from continental shores, pulling up cold, deoxygenated, CO2 and mineral rich deep waters to the surface where they fertilize the blooms of micro-algae that add more oxygen and feed the whole food chains of larger organisms in the oceans.

Atmosphere

Fig. 24. (top) Plan and (bottom) cross-section schematic view representations of the general circulation of the atmosphere. Three main circulations exist between the equator and poles due to solar heating and Earth’s rotation: 1) Hadley cell – Low-latitude air moves toward the equator. Due to solar heating, air near the equator rises vertically and moves poleward in the upper atmosphere. 2) Ferrel cell – A midlatitude mean atmospheric circulation cell. In this cell, the air flows poleward and eastward near the surface and equatorward and westward at higher levels. 3) Polar cell – Air rises, diverges, and travels toward the poles. Once over the poles, the air sinks, forming the polar highs. At the surface, air diverges outward from the polar highs. Surface winds in the polar cell are easterly (polar easterlies). A high pressure band is located at about 30° N/S latitude, leading to dry/hot weather due to descending air motion (subtropical dry zones are indicated in orange in the schematic views). Expanding tropics (indicted by orange arrows) are associated with a poleward shift of the subtropical dry zones. A low pressure band is found at 50°–60° N/S, with rainy and stormy weather in relation to the polar jet stream bands of strong westerly wind in the upper levels of the atmosphere. From Wikipedia Hadley Cell.

The atmosphere includes the gaseous components of Earth’s global heat engine. The transport and transfer of heat energy and the Coriolis effect are the major drivers. The major sources of heat are direct conduction of sensible heat across the atmosphere : ocean/land interface, the conversion of latent heat into sensible heat through the evaporation and condensation of water vapor (mainly from the oceans), and direct solar heating (note: because the atmosphere is largely transparent to most radiation, most solar energy is not captured by the atmosphere itself.)

The diagram here shows how the transport of heat from the Earth’s surface to the top of the atmosphere where it radiates away as infrared to the heat sink of outer space organizes the wind systems into three major cycles. Note that the moisture laden warm air cools as it rises and releases a lot more energy as the water vapor condenses into rain or hail to keep the rising air warmer for longer.

The  Biosphere (“Life”) – the totality of the living components of the planetary sphere, generally residing in the interface between the Atmophere and the Geosphere/Hydrosphere, where living things are characterized by their capacity to self-organize, self-regulate, and self-reproduce their properties of life through time.

Fig. 25. The biosphere of living things (NASA’s Goddard Space Flight Center, via Wikipedia). False colors are used to show seasonal changes in the concentration of chlorophyll over the annual cycle. On land, vegetation appears on a scale from brown (low to zero vegetation) to dark green (lots of vegetation); at the ocean surface, phytoplankton are indicated on a scale from purple (low) to yellow (high) and red (highest). This visualization was created with data from satellites including SeaWiFS, and instruments including the NASA/NOAA Visible Infrared Imaging Radiometer Suite and the Moderate Resolution Imaging Spectroradiometer.

The biosphere’s “Engine of Life” is predominantly driven by the complexly catalyzed formation of high energy chemical bonds from the capture of solar radiant or activation energy from redox reactions to combine oxygen and carbon to produce high energy carbohydrates (i.e., captured by chlorophyll in photosynthesis) used or ‘burned’ to fuel all kinds of metabolic activities and processes in living things. Living components of the Earth System have and depend for their continued survival and reproduction on their capacity to catalyze all kinds of energy transformations within and between the other Earth Systems. Over time the Engine of Life has profoundly affected the other planetary spheres. A tiny fraction of energy is captured in abyssal depths and deep in the earth through the process of chemosynthesis

Over evolutionary time the emergence and evolution Life has affected major global transformations involving many aspects of Earth’s other subsystems. Evolutionary processes are complexly dynamic and many of them include many potentially powerful positive feedbacks able to drive changes at exponential rates. All life can evolve genetically to live under a wide variety of environmental conditions over multi generational time scales due to natural selection at the genetic level. 

A few species and humans in particular, can evolve culturally at intra-generational timescales to drive changes at exponentially explosive rates to the extent that WE are literally threatening all complex life on the planet with global mass extinction – quite possibly within two or three of our own generations! 

Interpersonal competition to gain ever more personal power from the burning of globally significant quantities of  fossil carbon in less than a century that was accumulated in the geosphere over millions of years by life processes has destabilized Earth’s Climate System. TODAY, we seem to be in the midst of flipping the global climate system from the Glacial-Interglacial Cycle most life has adapted genetically to live under, to the Hothouse Earth regime that very few organisms will be able to survive in without hundreds or thousands of generations or more of genetic adaptation.
