Meteorologists report weather – they don’t make it!

William P. Hall on May 8, 2023

Meteorologists are being threatened and abused for forecasting and reporting record high temperatures and weather extremes.

Last week Spain recorded the highest April temperature on record (38.8 °C) following on from last year, 2022, its hottest year since records began.

Nearly 75 percent of Spain is susceptible to desertification due to climate change. Water reservoirs are at half their capacity and farmers unions say 60 percent of agricultural land is “suffocating” from lack of rain. Spain has asked Brussels to help by activating the EU’s agriculture crisis reserve funds (when many other areas of Europe are also suffering from drought).

Insults, Threats Target Spain Forecasters Over Climate ‘Conspiracy’

Spain’s government on Friday came to the defence of the AEMET weather agency, which has suffered threats and abuse from climate conspiracy theorists over its forecasts during a record drought.

“Murderers”, “Criminals”, “You’ll pay for this” and “We’re watching you” are just some of the anonymous messages sent to AEMET in recent weeks on social media, by email and even by phone.

The threats were responding to forecasts and reports published by AEMET, notably over last week’s early heatwave, when Spain registered its hottest-ever temperature for April, reaching 38.8 degrees Celsius (101.8 degrees Fahrenheit) in Cordoba.

Drought → crop failures → famine?

Where the European/Mediterranean region is concerned, Spain is not the only country facing water crises. Even before the end of winter, the Guardian’s article of 4 March, ‘Very precarious’: Europe faces growing water crisis as winter drought worsens, Austria, Germany, France, Italy and Switzerland were all suffering problems from shortages of rain and runoff from the small amount of accumulated winter snow.

Australia has already lost a lot of agricultural productivity because of three years of La Niña flooding. For several months we couldn’t even buy frozen french fries (shades of the Irish Potato Famine). This may well be followed by even more damaging droughts when the next major El Niño surpasses the last two to reach 1.5 °C above the pre-industrial baseline, as seems likely given past trends.

Climate scientists first laughed at a ‘bizarre’ campaign against the BoM – then came the harassment

Former Bureau of Meteorology staff say claims they deliberately manipulated data to make warming seem worse are being fed by a ‘fever swamp’ of climate denial.

For more than a decade, climate science deniers, rightwing politicians and sections of the Murdoch media have waged a campaign to undermine the legitimacy of the Bureau of Meteorology’s temperature records.

Those records say Australia has warmed by 1.4C since 1910, the year when the bureau’s main quality-controlled climate dataset starts.

Extremely hot days come along more often than they used to, and the warming trends are happening everywhere, at all times of the year.

As a target for those with an often visceral distrust of the established science of human-caused global heating, the bureau’s temperature record might be seen as ground zero.

“This has frankly been a concerted campaign,” says climate scientist Dr Ailie Gallant, of Monash University. “But this is not about genuine scepticism. It is harassment and blatant misinformation that has been perpetuated.”

Attacking messengers because you dislike or fear the messages only impedes circulating knowledge that might help to solve real-world problems and save your life or the lives of your family members. That global warming causes record temperatures and droughts is a fact that causes problems…. Denying the fact does not make the problems go away! It only keeps the problem from being solved until it is too late to do anything effective.

When there are too many crop failures over too wide an area for too long, famine is the consequence, and can lead to. Continuing famine leads to starvation and, eventually, mass deaths.

Bad news for whales and oceanic carbon capture

William P. Hall on May 6, 2023

Warming oceans are bad news for twilight zone organisms carrying captured carbon into the abyss when they die (and whales eat).

Climate change: life in ocean ‘twilight zone’ at risk from warming

Climate change could dramatically reduce life in the deepest parts of our oceans that are reached by sunlight, scientists warn.

Global warming could curtail life in the so-called twilight zone by as much as 40% by the end of the century, according to new research.

The twilight zone lies between 200m (656ft) and 1,000m (3,281ft).

It teems with life but was home to fewer organisms during warmer periods of Earth’s history, researchers found.

Ocean Twilight Zone – Woods Hole Oceanographic Institution, 04/05/2023

Why is it so important to understand life in the ocean twilight zone?

How much life is in the ocean twilight zone?

The twilight zone is home to more fish than the rest of the ocean combined. Most of these fish—and other organisms that live in the zone—are tiny, measuring just a few inches long or less. But some, like gelatinous siphonophores, can form chains that extend as much as 130 feet, making them among the biggest animals on Earth. Even the smallest twilight zone inhabitants can be powerful through sheer number, however. A tiny but fierce-looking fish called a bristlemouth is the most abundant vertebrate on the planet—for every one human, there are more than 100,000 bristlemouths. 

…

How does life in the twilight zone affect global climate?

By migrating to and from the surface, eating, being eaten, dying—and even by pooping—organisms in the twilight zone transport huge amounts of carbon from surface waters into the deep ocean. That process, called the biological pump, plays an important role in regulating Earth’s climate.

The science behind the observations

Katherin A. Chriton, et al. – 27/04/2023, Nature Communications

What the geological past can tell us about the future of the ocean’s twilight zone

Abstract: Paleontological reconstructions of plankton community structure during warm periods of the Cenozoic (last 66 million years) reveal that deep-dwelling ‘twilight zone’ (200–1000 m) plankton were less abundant and diverse, and lived much closer to the surface, than in colder, more recent climates. We suggest that this is a consequence of temperature’s role in controlling the rate that sinking organic matter is broken down and metabolized by bacteria, a process that occurs faster at warmer temperatures. In a warmer ocean, a smaller fraction of organic matter reaches the ocean interior, affecting food supply and dissolved oxygen availability at depth. Using an Earth system model that has been evaluated against paleo observations, we illustrate how anthropogenic warming may impact future carbon cycling and twilight zone ecology. Our findings suggest that significant changes are already underway, and without strong emissions mitigation, widespread ecological disruption in the twilight zone is likely by 2100, with effects spanning millennia thereafter. [my emphasis]

Why is all this important to know?

Ocean fertilization to stimulate algal growth over the surface of the abyssal ocean offers a means to capture CO₂. A food chain of pelagic consumers ranging from the twilight creatures harvesting the algae and their larger predators up to whales can then capture and package the carbon capturing algae into a range of parcels from fecal pellets to dead whales that will drop to the ocean floor.

The nature of biological systems is that they are self-reproducing and can grow exponentially under suitable conditions. ‘farming’ these consumers to optimize the carbon capture and transport it to the bottom is something that might realistically have the capacity to actually reduce atmospheric CO₂ on a fast enough timescale to slow, stop and reverse global warming.

However, the articles above show that a warming ocean substantially reduces the viability of the twilight organisms that provide the packaging service. Thus, if we don’t implement this biological sink before significantly more warming occurs, this opportunity to reverse the warming process may be lost.

Along with bristlemouth fish, krill are major components in the food chain of the twilight zone’s biological carbon pump potentially sequestering carbon in the abyssal depths of the world’s oceans. The world oceans’ surfaces, away from the shallows, are comparatively sterile because the water lacks micro nutrients (e.g., iron, manganese) required to support phytoplankton. Thus, vast areas of the oceans lack effective biological pumps to sequester carbon. Fertilizing these sterile areas of the oceans with trace nutrients and farming the twilight zone (i.e., seeding with appropriate species to provide the biological pumping mechanism) may establish a sufficiently extensive mechanism to sequester globally significant amounts of carbon in the abyssal depths.

Ominous climate crisis trends for 2023 onward

Climate News Links on May 4, 2023

Berkeley Earth shows March 2023 was abruptly warmer than February and tied for the 2nd warmest March globally since records began in 1850.

Berkeley Earth’s global temperature readings are ominous news where the climate crisis is concerned.

Berkeley Earth is an independent climatology research organization established in 2010 to systematically address five major concerns that global warming skeptics had identified, and did so in a systematic and objective manner. The first four were potential biases from data selection, data adjustment, poor station quality, and the urban heat island effect. Their analysis showed that these issues did not unduly bias the record. The fifth concern related to the over-reliance on large and complex global climate models by the Intergovernmental Panel on Climate Change (IPCC) in the attribution of the recent temperature increase to anthropogenic forces. They obtained a long and accurate record, spanning 250 years and showed that it could be well-fit with a simple model that included a volcanic term and, as an anthropogenic proxy, CO2 concentration.

Berkely Earth has several major objectives for their continuing work:

  • Further scientific investigations on the nature of climate change.
  • Continued identification, investigation, and illustration of opportunities for applications of our global temperature dataset and air pollution data, and work with global industries and governments to inform and support immediate and long-term decision-making on global warming. 
  • Continue as the world leader in the collection, analysis, and presentation of world air quality information. 
  • Establish and strengthen partnerships with national and international media, NGOs, industry leaders, government decision-makers to explore and promote ways to communicate and utilize our data.  
  • Increase the collection, analysis, and presentation of ocean data.

The climate science community accepts Berkeley Earth’s independently constructed reports among the standards used for cross-checking the accuracy of other reports (i.e., as independent observations of what should be the same reality).

The global mean temperature in March 2023 was 1.52 ± 0.10 °C (2.74 ± 0.18 °F) above the 1850 to 1900 average, which is frequently used as a benchmark for the preindustrial period. The global mean temperature anomaly in March 2023 exhibited a sharp increase in temperature relative to February 2023, rising more than 0.2 °C (0.36 °F). This was driven by sharp warming on land, 0.4 °C (0.72 °F), and moderate warming in the oceans, 0.1 °C (0.18 °F). Such large month-to-month shifts are uncommon, but not unheard of, occurring approximately 5% of the time.

March 2023 Temperature Update

Robert Rohde – 12/04/2023, Berkeley Earth

The following is a summary of global temperature conditions in Berkeley Earth’s analysis of March 2023.

  • Globally, March 2023 was abruptly warmer than February and tied for the 2nd warmest March since records began in 1850.
  • March global average temperatures exceeded 1.5 °C (2.7 °F) above the 1850 to 1900 baseline, becoming the 10th time this has occurred for a monthly average.
  • On land, March 2023 was the 2nd warmest March since 1850.
  • Warm conditions occurred in much of Asia, parts of Europe and North Africa, the Arctic, southern South America, and several oceanic regions.
  • Unusually cool conditions were present in parts of the Western United States and Canada, as well as much of the Southern Pacific.
  • The Pacific exhibits neutral conditions with a transition to El Niño considered likely later this year.
  • 2023 is on pace to be the 2nd, 3rd, or 4th warmest year, but considerable uncertainty remains, including a substantial 38% likelihood that 2023 could become a new record warm year.

The global heat rise in March and April is more than reflected in the average sea-surface temperature (SST) anomaly over most of the Earth outside the polar regions not included in the following measurements depicted by the University of Maine’s ClimateReanalyzer.org, whose supercomputers reconstruct and record a wide range of climate observations from many thousands to millions of data points for the planet every day. Even as the SST is falling significantly at the end of April after reaching an all-time record, it is still way higher than any previous record for this time of the year.

Some idea of the quality and magnitude of the input data can be found by following the links below the graphics in this document.

Current sea surface temperatures also indicate the likelihood that the next El Niño is brewing that will drive global average (and many local) temperatures to new record highs.

Sea Surface Temperaure Anomalies for 2 April 2023. Climate Reanalyzer / Climate Change Institute / University of Maine. Note the anomalous patch of very hot water west of the equatorial coast of South America and the warm patch extending west of this along the Equator. This is a strong indicator for a developing El Niño condition.

We can conclude from these observations, that there is no evidence that the process of global warming has stopped or even slowed. If we don’t stop it soon, humans – and for that matter – all life on Earth will suffer from the failure. Political as well as personal action is required if we are to give our offspring a viable future.

Human survival depends on total mobilization to fight global warming

William P. Hall on December 11, 2022

Australian security leaders including the ex Defence Force Chief, Chris Barrie, and Air Force Deputy Chief, John Blackburn warn that global mobilization is required to deal with the existential threat (i.e., human extinction) from global warming: “Global inaction has resulted in climate change becoming an immediate existential threat to humanity and, together with nuclear war, is the greatest threat to the security of Australia and its people: “Global inaction has resulted in climate change becoming an immediate existential threat to humanity and, together with nuclear war, is the greatest threat to the security of Australia and its people.”

I have said this myself many times, e.g., On the down-hill road to extinction and in other posts on Climate Sentinel News — but here it is being said by people who should matter to our Parliaments.

Australia needs ‘wartime mobilisation’ response to climate crisis, security leaders say

Australian Security Leaders Climate Group says measures needed to contain climate change will be disruptive, but better than ‘existential threat’ of the alternative

Australia must adopt a “wartime mobilisation” response to the climate emergency, former security leaders have told a review of the country’s defence policy.

The Australian Security Leaders Climate Group is calling for “a fundamental reframing of Australia’s defence and security strategy” away from geopolitical rivalry.

The group – whose members include the former Australian defence force chief Chris Barrie and former air force deputy chief John Blackburn – argues the country must push for unprecedented global cooperation on the climate crisis.

Despite the US and Australia vowing on Wednesday to “drive stronger global action to address the climate crisis”, the security leaders insist the issue is still being treated as an afterthought rather than a top-order threat.

Read the complete article….

Voters need to ensure that our elected representatives take the climate emergency as seriously as our Defence chiefs do, and enact the necessary laws and provide the necessary leadership to ensure this effort is mobilized at state, national and international levels.

Featured Image from The Strategist (The Australian Strategic Policy Unit) article, Australia needs to build total defence in the face of national crises The following quote is also from that source:

In Australia, the prevailing view of mobilisation is that it is an activity associated with going to war. In the event of an armed conflict, the nation mobilises to support the Australian Defence Force. Against recent events, including the 2019–20 bushfires and Covid-19 pandemic, the ADF has mobilised to support the nation. As the range of potential hazards now encompasses high-end warfighting, grey-zone conflict, terrorism and organised crime, as well as domestic and offshore natural disasters, no single institution can sufficiently respond on its own.

Mobilisation should be redefined as occurring in response to all such events, drawing on all required and available elements from across the breadth of Australian society. But it must not be seen as just the response to a crisis; it should also include preparing for and, where possible, preventing such events, as well as supporting subsequent recovery efforts.

Urgent action needed now to stop warming!

William P. Hall on August 23, 2022

Aside from some flooding Australia has had it fairly easy compared to increasing frequency, extent, and severity of climate catastrophes in other parts of the world.

Don’t let our cooler La Nina and Indian Ocean dipole conditions fool you. The rest of the world really suffering!

Bill McKibben, is an American environmentalist, author, and journalist who has written extensively on the impact of global warming and and leads the climate campaign group 350.org. Here he summarizes evidence from increasingly frequent, extensive, and ferocious climate catastrophes in the Northern Hemisphere that shows global warming is continuing to accelerate.

As many articles posted on Climate Sentinel News in the run-up to Australia’s May 21 federal election also show, nothing we have done to date has measurably slowed the acceleration of global warming that may well lead to runaway warming and global mass extinction of humans and most other complex life on Earth. To stop this process while we can, our nations need to actively mobilize now to stop all carbon emissions and begin rapidly ramping up research and pilot projects to recapture and safely sequester some of the excess carbon already in our atmosphere.

Removing our COALition Government and electing several more ‘teal’ community independents to Parliament in the election just passed has finally given us a Labor Government that might be able to prioritize real climate action. However, because Labor continues to have its share of special interest puppet masters in the fossil fuel industry, pressure still needs to be applied by voters and their teal representatives in Parliament to speed climate action.

As the featured article here shows, we are already seeing the kinds of climate catastrophes able to cause mass human die-off events directly from the climate extremes themselves or famines resulting from associated crop failures.

Water, Water Nowhere – Except the spots that are flooding

China is enduring a truly remarkable heatwave—by some accounts “the worst heatwave known in world climatic history.” (Its main competitor for the title may be last year’s insane ‘heat dome’ that ran Canadian temperatures up to 121 Fahrenheit). The heat just never lets up over some of the most densely populated land on planet earth: It hit 113 degrees Fahrenheit in Chongqing Thursday, the highest temperature ever recorded in the country outside of desert Xinjiang. It hit 110 in Sichuan, which is a province of…80 million people, or two Californias. When it gets that hot, water just evaporates—Sichuan is 80 percent dependent on hydropower, but the reservoirs behind the great dams like Three Gorges are falling nearly as fast as Lake Mead and Lake Powell. The province has cut power day after day, including to Tesla and Toyota factories, and to many of the firms that supply the planet’s auto parts; the EV revolution is being held up by the effects of the problem it is trying to solve.

July 2022 Climate – still on road to extinction

William P. Hall on July 31, 2022

Australia has a new government. Every month we fail to stop global warming is a month closer to global mass extinction. Still no visible progress towards solution.

https://nsidc.org/arcticseaicenews/charctic-interactive-sea-ice-graph/

The graphic above downloaded today shows the current state of sea-ice surrounding the Antarctic continent. Despite what seems to be a cold winter in Victoria, its coverage indicated by the teal blue line in the chart is 530 km2 smaller than it has ever been before for this time of the year. There are many more indicators that the climate is still deteriorating towards making Earth uninhabitable for its present life forms (including humans!) at an accelerating rate.

The following news items underline the dangers this represents for humans.

Model-analyzed temperatures at 12Z Tuesday, July 19, 2022 (noon GMT) were transcending average values for the time of day and season by 12 to 24 degrees Celsius—or 22 to 33 degrees Fahrenheit—over large parts of northwestern Europe. (Image credit: tropicaltidbits.com) [from the article]

Horrific heat descends upon Western Europe: 104°F in London

Dozens of all-time record highs melted on Monday and Tuesday under a searing, deadly European heat wave that has caused at least 1,169 heat-related deaths in Spain and Portugal. The heat wave has also brought the hottest day on record for many locations in France and the hottest temperatures — by far — ever observed in the United Kingdom.

The record-smashing heat in Europe’s normally mild, maritime northwest corner was eerily comparable to the astounding heat wave in the U.S. Pacific Northwest and far southwest Canada in June 2021. The latter was found to have been “virtually impossible” without human-produced climate change.

By 9 a.m. GMT on Tuesday, July 19, London’s Heathrow Airport had already surged past 90°F, and at 12:50 p.m., the airport’s official observing site for London recorded what, if confirmed, would be the hottest temperature in London history: 40.2 degrees Celsius, or 104.4 degrees Fahrenheit.

‘Soon it will be unrecognisable’: total climate meltdown cannot be stopped, says expert

Blistering heatwaves are just the start. We must accept how bad things are before we can head off global catastrophe, according to a leading UK scientistRobin McKie.

The publication of Bill McGuire’s latest book, Hothouse Earth, could not be more timely. Appearing in the shops this week, it will be perused by sweltering customers who have just endured record high temperatures across the UK and now face the prospect of weeks of drought to add to their discomfort.

And this is just the beginning, insists McGuire, who is emeritus professor of geophysical and climate hazards at University College London. As he makes clear in his uncompromising depiction of the coming climatic catastrophe, we have – for far too long – ignored explicit warnings that rising carbon emissions are dangerously heating the Earth. Now we are going to pay the price for our complacence in the form of storms, floods, droughts and heatwaves that will easily surpass current extremes.

In the run-up to the May 21st Federal Election, I posted many more articles documenting the increasing risk of mass extinction that humans face if we do not stop and reverse the runaway acceleration that is flipping our global climate to the Hothouse Earth state.

In the Election Australians replaced the Liberal/National COALition with a more climate friendly Labor government supported by an extensive cross-bench of climate-friendly independents (‘teals‘) and Greens.

The Government has very little time (if any – see the article above) to act to stop carbon emissions and to do what we can to remove some of the past excesses from the atmosphere.

TIME IS OF THE ESSENCE!

The carbon dioxide data on Mauna Loa shown in the top row constitute the longest record of direct measurements of CO2 in the atmosphere. They were started by C. David Keeling of the Scripps Institution of Oceanography in March of 1958 at a facility of the National Oceanic and Atmospheric Administration [Keeling, 1976]. The first graph shows atmospheric CO2 concentrations over the last five complete years of the Mauna Loa CO2 record plus the current year. The second graph shows annual mean CO2 growth rates for Mauna Loa. In the graph, decadal averages of the growth rate are also plotted, as horizontal lines for 1960 through 1969, 1970 through 1979, and so on.

The middle row charts the growth of atmospheric methane: the first graph shows the full NOAA time-series starting in 1983, The red circles are globally averaged monthly mean values centered on the middle of each month. The black line and squares show the long-term trend (in principle, similar to a 12-month running mean) where the average seasonal cycle has been removed.The second graph summarizes annual increases in atmospheric CH4 based on globally averaged marine surface data.

The bottom row charts the growth of atmospheric N2O (Nitrous oxide) beginning in 2001, when NOAA began to have confidence in the data. Values for the last year are preliminary pending recalibrations of standard gases and other quality control steps. The second graph plots the annual increase in atmospheric N2O in a given year, i.e., the increase in its abundance (mole fraction) from January 1 in that year to January 1 of the next year, after the seasonal cycle has been removed (as shown by the black lines in the first figure). It represents the sum of all N2O added to, and removed from, the atmosphere during the year by human activities and natural processes.

As yet, there is NO evidence that any of these values are beginning to stop increasing, let alone decrease, as the result of any human actions.

S Hemisphere already seeing 2080 storms now

Climate News Links on May 30, 2022

New studies show winter storms in the Southern Hemisphere are already reaching intensities predicted for 2080. Climate emergency is real!

By Weizmann Institute of Science, 26 May 2022 in Phys Org

New data reveals climate change might be more rapid than predicted

A new study, published today in Nature Climate Change, will certainly make the IPCC—and other environmental bodies—take notice. A team of scientists led by Dr. Rei Chemke of Weizmann’s Earth and Planetary Sciences Department revealed a considerable intensification of winter storms in the Southern Hemisphere. The study, conducted in collaboration with Dr. Yi Ming of Princeton University and Dr. Janni Yuval of MIT, is sure to make waves in the climate conversation. Until now, climate models have projected a human-caused intensification of winter storms only toward the end of this century. In the new study, Chemke and his team compared climate model simulations with current storm observations. Their discovery was bleak: It became clear that storm intensification over recent decades has already reached levels projected to occur in the year 2080.

…

Chemke, Ming and Yuval’s study has two immediate, considerable implications. First, it shows that not only climate projections for the coming decades are graver than previous assessments, but it also suggests that human activity might have a greater impact on the Southern Hemisphere than previously estimated. This means that rapid and decisive intervention is required in order to halt the climate damage in this region. Second, a correction of the bias in climate models is in order, so that these can provide a more accurate climate projection in the future.

UN global assessment report on disaster risk reduction

New UN report forecasts an increasing frequency of colliding and concatenating climate catastrophes and disasters from global warming

A car is flipped over after a tornado tore through the area in Arabi, La., Tuesday, March 22, 2022 in a part of the city that had been heavily damaged by Hurricane Katrina 17 years earlier. A United Nations report release on Monday, April 25, 2022, says disasters are on the rise and are just going to get worse.

Weary of many disasters? UN says worse to come

A disaster-weary globe will be hit harder in the coming years by even more catastrophes colliding in an interconnected world, a United Nations report issued Monday says.

If current trends continue the world will go from around 400 disasters per year in 2015 to an onslaught of about 560 catastrophes a year by 2030, the scientific report by the United Nations Office for Disaster Risk Reduction said. By comparison from 1970 to 2000, the world suffered just 90 to 100 medium to large scale disasters a year, the report said.

The number of extreme heat waves in 2030 will be three times what it was in 2001 and there will be 30% more droughts, the report predicted. It’s not just natural disasters amplified by climate change, it’s COVID-19, economic meltdowns and food shortages. Climate change has a huge footprint in the number of disasters, report authors said.

Climate change: Key UN finding widely misinterpreted: A key finding in the latest IPCC climate report has been widely misinterpreted, according to scientists involved in the study:

A major challenge in communicating complex messages about climate change is that the more simplified media reports of these events often have more influence than the science itself.

This worries observers who argue that giving countries the impression that emissions can continue to grow until 2025 would be a disaster for the world.

“We definitely don’t have the luxury of letting emissions grow for yet another three years,” said Kaisa Kosonen from Greenpeace.

“We have eight years to nearly halve global emissions. That’s an enormous task, but still doable, as the IPCC has just reminded us – but if people now start chasing emissions peak by 2025 as some kind of benchmark, we don’t have a chance.”

Editor’s note: Based on my rigorous evaluation of the IPCC’s scientific methodology and writing processes, even the corrected understanding of the IPCC report STILL UNDERSTATES the likelihood of the risk from, and the magnitude of consequences of failures or even delays in stopping the progress of global warming. In reality, the report says it is already too late to avoid global average temperatures rising more than 1.5 °C. By reaching net zero in 2030 AND extracting and sequestering most of the excess CO₂ already in the atmosphere we might be able to bring temperatures back down to 1.5 °C or less. Continuing with business as usual keeps us on the road to runaway warming to Earth’s Hothouse Hell and social collapse leading towards global mass extinction of humans and most other large and complex organisms on the planet.

Global warming report for March 2022 shows rise

Climate News Links on April 17, 2022

James Hansen’s March 2022 global average temperature still trending up (close to all-time record for the month) when temps normally drop

March Temperature Update & Butterfly Report

March was notably warm (Fig. 1), more than 1.3°C warmer than the average March in 1880-1920, despite continued La Nina cooling of the Pacific. Because of the present planetary energy imbalance – discussed in prior posts – we expect 2022 to be substantially warmer than 2021. [my emphasis] The imbalance is due to surging growth rates of GHGs (greenhouse gases), solar irradiance rising from its recent minimum, and perhaps the aerosol forcing becoming less negative, although the latter remains speculative given the absence of measurements of the global aerosol forcing.

The imbalance – excess energy coming in – is not enough to push the 2022 annual temperature above the 2020 record, but it will soon do that. Meanwhile, models forecasting the tropics favor continuation of the La Nina this summer, which favors strong tropical storms.
