A brutal, record-intensity heat wave that has engulfed much of India and Pakistan since March eased somewhat this week, but is poised to roar back in the coming week with inferno-like temperatures of up to 50 degrees Celsius (122°F). The heat, when combined with high levels of humidity – especially near the coast and along the Indus River Valley – will produce dangerously high levels of heat stress that will approach or exceed the limit of survivability for people outdoors for an extended period.
The latest forecasts from the GFS and European models predict an unusually strong region of high pressure intensifying over southern Asia in the coming week, bringing increasing heat that will peak on May 11-12, with highs near 50 degrees Celsius (122°F) near the India/Pakistan border. May is typically the region’s hottest month, and significant relief from the heat wave may not occur until the cooling rains of the Southwest Monsoon arrive in June. But tropical cyclones are also common in May in the northern Indian Ocean, and a landfalling storm could potentially bring relief from the heat wave.
Smoke and Sandstorm, Seen From Space: A time-lapse image of smoke from wildfires in New Mexico and dust from a storm in Colorado illustrates the scope of Western catastrophe.
The video is mesmerizing: As three whitish-gray geysers gush eastward from the mountains of New Mexico, a sheet of brown spills down from the north like swash on a beach.
What it represents is far more destructive.
The image, a time-lapse captured by a National Oceanic and Atmospheric Administration satellite, shows two devastating events happening [at the same time] in the Western United States. The first is a wildfire outbreak in northern New Mexico that started last month and has intensified in the past two weeks, fueled by extreme drought and high winds. The second is a dust storm caused by violent winds in Colorado.
Both are examples of the sorts of natural disasters that are becoming more severe and frequent as a result of climate change.

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

A United Nations report release on Monday, April 25, 2022, says disasters are on the rise and are just going to get worse. A new UN report says the number of disasters, from climate change to COVID-19, are going to jump to about 560 a year by 2030. (AP Photo/Herald Herbert)
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.

Editors Comment: We have important choices to make in the upcoming election: Vote for our business as usual government who still largely act as if there was no emergency (e.g., keep shoveling as much coal as they can onto the fires of global warming), won’t prepare for disasters, and won’t hold a hose when a disaster happens; or you can try to elect candidates who have provided evidence that they will put action on the climate emergency at the top of their Parliamentary agendas. If you make the latter choice, Vote Climate One gives you Climate Sentinel News to inform your decision and our Traffic Light Voting Guides for every Australian electorate to show you how each candidate in your electorate ranks on climate action.

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.

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.

Our food system isn’t ready for the climate crisis: The world’s farms produce only a handful of varieties of bananas, avocados, coffee and other foods – leaving them more vulnerable to the climate breakdown
The climate breakdown is already threatening many of our favorite foods. In Asia, rice fields are being flooded with saltwater; cyclones have wiped out vanilla crops in Madagascar; in Central America higher temperatures ripen coffee too quickly; drought in sub–Saharan Africa is withering chickpea crops; and rising ocean acidity is killing oysters and scallops in American waters.
All our food systems – agriculture, forestry, fisheries and aquaculture – are buckling under the stress of rising temperatures, wildfires, droughts, and floods.
Even in the best-case scenario, global heating is expected to make the earth less suitable for the crops that provide most of our calories. If no action is taken to curtail the climate crisis, crop losses will be devastating.
The physical laws of thermodynamics rule that it takes a lot of energy to capture wide-spread rare gas molecules into a tight space
The article below extrapolates the costs of ‘proven’ technologies for direct air capture and sequestration of CO₂. To have any hope of cleansing our planet’s atmosphere, MILLIONS of these complex engineered contraptions would have to be manufactured, transported, and installed around the world. Of course, the fossil fuel industry would love to take on the task of doing this because of the trillions of dollars to be made from building the devices and producing the vast amounts of fuel required to make them work to reduce the entropy of the gas molecules emitted from driving the machines capturing the gas.
Plants already do this work using solar energy. They too are inefficient, but they use the small fraction of the solar energy captured that passes through their cells to grow more and ever more plants until space and/or their simple nutrients are used up. Nevertheless, they are self-reproducing and grow exponentially as long as they can, capturing CO₂ to make the sugars they use for fuel and building blocks for their structures. As long as the carbon remains captured in living or dead plant matter it is well concentrated and easily sequestered.
With appropriate changes farming and forestry techniques a lot of carbon can be captured and sequestered; but potentially much more can be done by fertilizing AND FARMING the nearly sterile areas of ocean over abyssal depths These comprise approximately 1/5 of the Earth’s total unfrozen surface. The US National Academies of Science, Engineering, Medicine (2021) A Research Strategy for Ocean-based Carbon Dioxide Removal and Sequestration — especially Chapter 3, Nutrient Fertilization provides an excellent review.
The Featured Image above, based on satellite tracking of the amount of chlorophyll-a in the oceans shows ocean deserts (i.e., areas where there is virtually no chlorophyll – and thus no photosynthesis) as dark blue or purple. Even some of the lighter blue areas might also be made more productive with fertilization.
The National Academies report considers mainly the first part of the process – fertilization mainly by providing iron in micronutrient quantities. This is often all that is required to enable large blooms of microalgae, but the blooms also can cause problems, and the individual algal cells aren’t large enough to sink the carbon they capture out of the zone where decomposition soon releases the carbon back to the atmosphere.
What is missing in the National Academies report is the need for active seeding and farming of appropriate ecosystems of consumers to eat and package the microalgal carbon content into fecal pellets and dead bodies dense enough to sink into the abyssal depths where the carbon will be incorporated into the bottom sediment. However, unlike mechanical contrivances that have to be manufactured, once the appropriate mix of ‘seeds’ is worked out, the suite of consumer organisms will also with some appropriate tweaking by the farmers, self-reproduce and grow exponentially to meet the demand,
Yes, it is quite likely there will be eggs broken and catastrophic major failures (easily stopped by stopping the algal fertilization with iron), but if we don’t have other proven means of sequestration, the price of not trying this reasonably quick and thermodynamically plausible solution could well be the completion of global mass extinction and the end of the human species.
Direct Air Capture installation / from the article
Removing CO2 directly from the air requires almost as many joules as those produced by burning the fossil fuel in the first place, writes Leigh Collins
Capturing CO2 emissions using direct-air-capture (DAC) technology requires almost as much energy as that contained in the fossil fuels that produced the carbon dioxide in the first place, according to new analysis.
In 2020, the world used 462 exajoules (EJ) of energy from fossil fuels, which resulted in 32 billion tonnes of CO2 emissions. Capturing that carbon dioxide through DAC — which sucks the greenhouse gas out of the air — would require 448EJ, according to calculations by Australian maths-as-a-service company Keynumbers.
Scotty from marketing and his fellow puppets work assiduously to protect fossil fuel multibillionaires (not all of them are even Australian – e.g., Adani) and make them even richer. And then there was Clive Palmer last week
However, I think Australia has at least one multi-billionaire who is already doing a lot to develop ‘green’ industries to minimize carbon emissions. Dr Andrew Forrest (i.e., ‘Twiggy’), Australia’s second richest person last time I looked, may have stepped on more than a few toes building his industrial empire, but I am unaware of any other person who parked his industries and iron mines in a charitable foundation and spent several years EARNING a doctorate in marine sciences and establishing a substantial marine sciences lab, aside from pledging upwards of a billion dollars to establish zero emissions mining and manufacturing systems.
Hopefully we can elect the kind of people to our Parliament who have the foresight, understanding and integrity to persuade and work with people like Forrest who seems inclined to invest significant fractions of their private resources in the fight against likely runaway global warming. Unfortunately, several narcissistic and hedonistic multibillionaire fossil fuel special interests are doing a very effective job persuading their current Parliamentary puppets to spend public resources shoveling more carbon fuel onto the fires of global warming.
In his own words, Scotty makes it blindingly obvious that he is vastly more interested in stoking his patrons’ fossil fuel fires than in stopping their emissions to mitigate global warming and the possible mass extinctions of humans and the millions of other species of life we share our planet with.
Prime Minister Scott Morrison says he is supportive of Australia’s fossil fuel industry – and particularly coal, which he… says will be around for “decades to come”. “When it comes to the coal industry, it’s worth $35 billion to us every year in exports, and that’s money Australia needs to grow our economy,” Mr Morrison said. “What you need in today’s energy economy is you need to continue to run your coal-fired power stations for as long as you possibly can and that is our policy … we want them to run as long as they possibly can.” Coal-fired power stations will continue to run to back up renewable power sources, although Mr Morrison said gas would play a larger role in the energy mix in years to come. Mr Morrison added that building a new coal-fired power station would be difficult because of the state government planning powers, which would “probably never allow them to do it”. For the video see: The Australian, 14/03/2022, Commentary/coal-will-be-around-for-decades-to-come-scott-morrison/video. See also ‘We will keep mining’, says Australian prime minister Scott Morrison about the future of coal.
If that wasn’t enough, here’s a choice of some more of Scotty’s thinking about stopping the Apocalypse of global warming
We need to turn away from the the Apocalypse on the road to hothouse hell, and we won’t do this by continuing with business as usual!
It seems to have taken the clear thinking of Greta Thunberg, a 16 year-old girl who concluded school was pointless as long as humans continued their blind ‘business as usual’ rush towards extinction.
Listen to Greta’s speech live at the World Economic forum in Davos 2019. Except for her reliance on the IPCC’s overoptimistic emissions budget, everything she says is spot on that even she, as a child, can understand the alternatives and what has to happen.
In other words, wake up! smell the smoke! see the grimly frightful reality, and fight the fire that is burning up our only planet so we can give our offspring a hopeful future. This is the only issue that matters. Even the IPCC’s hyperconservative Sixth Assessment Report that looks at climate change’s global and regional impacts on ecosystems, biodiversity, and human communities makes it clear we are headed for an existential climate catastrophe if we don’t stop the warming process.
Scott Morrison and his troop of wooden-headed puppets are doing essentially nothing to organize effective action against the warming. In fact all they doing is rearranging the furniture in the burning house to be incinerated along with anything and everyone we may care about.
In Greta’s words, “even a small child can understand [this]”. People hope for their children’s futures. She doesn’t want your hopium. She wants you to rationally panic enough to wake up, pay attention to reality, and fight the fire…. so our offspring can have some hope for their future. Vote Climate One’s Traffic Light Voting System will help you use your preferential votes wisely on behalf of our offsprings’ future.
Let’s hope that we can stop global warming soon enough to leave them with a future where they can survive and flourish.

Results: Extreme single-day fire spread events >1,100 ha (the top 16%, >1 SD) accounted for 70% of the cumulative area burned over the period of analysis. The variation in annual area burned was closely tied to the number and mean size of spread events and distributional skewness towards more large events. For example, we identified 441 extreme events in 2020 that together burned 2.2 million ha across our study area, in contrast to an average of 168 per year that burned 0.5 million ha annually between 2002 and 2019. Fire season climate variables were correlated with the annual number of extreme events and area burned. Our models predicted that the annual number of extreme fire spread events more than double under a 2°C warming scenario, with an attendant doubling in the area burned.
Conclusions: Exceptional fire seasons like 2020 will become more likely, and wildfire activity under future extremes is predicted to exceed anything yet witnessed. Safeguarding human communities and supporting resilient ecosystems will require new lines of scientific inquiry, new land management approaches and accelerated climate mitigation efforts.

Part III of the IPCC’s 6th Assessment published late on 4 April says net zero alone won’t stop global warming. Carbon capture is also needed.
According to the Third Part of the IPCC’s 6th Assessment Report published this week, our last chances to stop and reverse the still accelerating global warming are running out of time. If we don’t act effectively within the next three years or so, humanity will be condemned to extreme hardship and dieoffs as increasingly large areas of our only planet become effectively uninhabitable because of high temperatures and extreme weather, and our agricultural systems also begin to fail for the same reasons. I have already commented extensively on Parts I and II of the report and consequently have reached and written about many of the topics covered in Part III, and my conclusions from the evidence are even more grim than the IPCC’s. So, other than providing a bit of background on the IPCC and possible limitations of their authoring process, in this post I simply present links to 12 independent commentaries.
Background
The Intergovernmental Panel on Climate Change (!PCC) was established by the United Nations in 1988 to study and make recommendations relating to climate changes triggered by the greenhouse gas released into the atmosphere beginning in the Industrial Revolution by the burning of coal and other fossil carbons for energy production. It presents the most solidly based and peer reviewed scientific understanding of the rapidly expanding climate crisis there is. However, because of its political and academic foundations it has and will consistently under-represent novel and extreme consequences of the on-going global warming. (The reasons for this scientific reticence or ‘conservatism‘ are discussed and explained in detail in my presentation: Some fundamental issues relating to the science underlying climate policy: The IPCC and COP26 couldn’t help but get it wrong.)
However, even in the face of these constraints, the AR6 part 3 Report: Climate Change 2022 – Mitigation of Climate Change, accepts and is based on the extensive research reported in parts 1 and 2 of the full report that failure to stop and reverse global warming before temperatures reach 2.0 °C (or preferably 1.5 °C) will be catastrophic for humans and the biosphere.
Where are we now with the physical state of our atmosphere that drives climate change
NOAA Trends in atmospheric greenhouse gases as at 8 April 2022 / Data source NOAA Global Monitoring Laboratory, Carbon Cycle Greenhouse Gases. / William Hall
The rising concentrations of the three most important greenhouse gases shown above record the physical physical measurements in parts per million or parts per billion (compared to the total number of gas molecules of any kind in the atmosphere) as reported from the Mouna Loa (Hawaii) climate observatory. Details on how the samples were collected, processed and measured are available on the observatory web site. One thing worth noting, is that the longest base-line record from the observatory itself at 3400 meters elevation in the oceanic sub-tropics (shown here) that peaked in February is not identical to the worldwide average CO₂ from multiple sites shown for the Global Monthly Mean CO2 that is still rising in March. NH₄ and N₂O graphs show global means.
It is also worth nothing that the atmospheric concentrations for all of the gases reflect both human generated emissions AND the Earth’s ‘natural’ emissions for each year. We can control human emissions, but the natural emissions increase significantly with each rise in global average temperature.
The chart below shows RELATIVE changes in the global average temperature for each year relative to the global temperature averaged over the 30 years years 1951 through 1980. Earth’s temperature is based on a balance between the absorption of energy from solar radiation at ‘visible’ wave lengths by the planet and everything on it, and the emission of infrared energy by the planet and everything on it. Greenhouse gases heat the planet by blocking some outgoing infrared wave lengths causing the planet to warm until enough energy can be emitted at shorter (more energetic) wavelengths to balance the incoming visible radiation. Again this is a purely physical process that can be measured to relatively high precision.
Global average temperature datasets from NASA, NOAA, Berkeley Earth, and meteorological offices of the U.K. and Japan, show substantial agreement concerning the progress and extent of global warming: all pairwise correlations exceed 98%. / CC BY-SA 4.0 File:20200324 Global average temperature – NASA-GISS HadCrut NOAA Japan BerkeleyE.svg (Version 12) – for more details on sources and construction of the graph see: Wikimedia Commons.
The early trends illustrated by these facts are what drove the formation of the IPCC and its series of increasingly desperate calls to action in its series of “Assessment Reports” involving thousands of well qualified research scientists working as authors over the years of it existence. The 6th Assessment Report discussed here consists of 3 parts: I – The Physical Science Basis: 3949 pages, published 7 Aug 2021; II – Impacts, Adaptation and Vulnerability: 3675 pages, published 27 Feb 2022, and III – Mitigation of Climate Change: 2913 pages, published 4 April 2022. Together the full 3 part report includes 10,537 pages of meticulously peer-reviewed content. My December 202 presentation, Some fundamental issues relating to the science underlying climate policy: The IPCC and COP26 couldn’t help but get it wrong details the IPCC’s rigorous processes for producing the reports. My major criticism is that these processes add years of delay between scientific observations and publication, that the political and academic/institutional environments lead to reticence and understatement of risks, and that an over-reliance on mathematization gives the impression that complexly and chaotically dynamical systems such as the generation of weather and climate are more accurate than they can actually be.
Whatever humbug our governments tell us, we won’t know if we can get off the road to Earth’s Hothouse Hell state until all of the above curves are actually trending downward. As long as they point upwards, it is a clear indication that we are headed towards runaway warming and the unsurvivable hothouse.
Simply stated, where the IPCC observes that the future of humanity is dire, the reality is that it will probably be even worse than that.
What do others make of the IPCC’s Part III report?
Following are 12 independent takes on the IPCC’s recommendations for what we can do that might mitigate the global warming that is already dialed into Earth’s Climate System. Urgently stopping human carbon emissions on its own is no longer enough to stop warming soon enough to avoid major catastrophic damage. We will also have to remove excess carbon from the atmosphere with still unproven technolgies:

Radical emissions cuts combined with some atmospheric carbon removal are the only hope to limit global warming to 1.5 °C, scientists warn.
Humanity probably isn’t going to prevent Earth from at least temporarily warming 1.5 °C above pre-industrial levels — but aggressive action to curb greenhouse-gas emissions and extract carbon from the atmosphere could limit the increase and bring temperatures back down, according to the latest report from the United Nations Intergovernmental Panel on Climate Change (IPCC). The report makes it clear, however, that the window is rapidly closing, and with it the opportunity to prevent the worst impacts of global warming. Above the 1.5 °C limit — set by the Paris climate agreement in 2015 — the chances of extreme weather and collapsing ecosystems grow.
If the world acts now, we can avoid the worst outcomes of climate change without any significant effect on standards of living. That’s a key message from the new report from the Intergovernmental Panel on Climate Change (IPCC).
The key phrase here is “acts now”. Jim Skea, co-chair of the IPCC working group behind the report, said it’s “now or never” to keep global warming to 1.5℃. Action means cutting emissions from fossil fuel use rapidly and hard. Global emissions must peak within three years to have any chance of keeping warming below 1.5℃.
Unfortunately, Australia is not behaving as if the largest issue facing us is urgent – in fact, we’re doubling down on fossil fuels.
In recent years, Australia overtook Qatar to become the world’s largest exporter of liquefied natural gas (LNG). We’re still the second-largest exporter of thermal coal, and the largest for metallurgical coal.
A new report from the UN’s Intergovernmental Panel on Climate Change (IPCC) outlines what progress has been made in tackling global warming so far – and what will be needed for the world to curb emissions and achieve its climate targets.
It is the third part of the IPCC’s sixth assessment report (AR6), a process that comes around every six or seven years and aims to provide a comprehensive view of the state of knowledge on climate change. (See Carbon Brief’s in-depth Q&A.)
…
This report, by the IPCC’s Working Group III (WG3) “provides an updated global assessment of climate change mitigation progress and pledges, and examines the sources of global emissions”
Greenhouse gas emissions must peak by 2025, say climate scientists in what is in effect their final warning.
The world can still hope to stave off the worst ravages of climate breakdown but only through a “now or never” dash to a low-carbon economy and society, scientists have said in what is in effect a final warning for governments on the climate.
Greenhouse gas emissions must peak by 2025, and can be nearly halved this decade, according to the Intergovernmental Panel on Climate Change (IPCC), to give the world a chance of limiting future heating to 1.5C above pre-industrial levels.
The final cost of doing so will be minimal, amounting to just a few percent of global GDP by mid-century, though it will require a massive effort by governments, businesses and individuals.
But the chances were narrow and the world was failing to make the changes needed, the body of the world’s leading climate scientists warned. Temperatures will soar to more than 3C, with catastrophic consequences, unless policies and actions are urgently strengthened.
The latest major climate assessment outlines the urgency and feasibility of rapid decarbonization to preserve the economy, health, and a stable climate.
In the just-released third installment of its Sixth Assessment Report (the first two volumes covered climate change causes and impacts), the Intergovernmental Panel on Climate Change (IPCC) summarizes the latest scientific research on efforts to mitigate climate change. Written by 278 authors from 65 countries, the new report can be summarized in one word: “urgency.”
To meet the Paris targets, the IPCC says that global emissions must peak immediately; that governments have not yet implemented sufficient policies to make that happen; and that continued expansion of fossil fuel infrastructure would create additional stranded assets potentially amounting to trillions of dollars in lost investments.

“Climate activists are sometimes depicted as dangerous radicals, but the truly dangerous radicals are the countries that are increasing the production of fossil fuels.” – United Nations Secretary General Antonio Guterres
I’m a climate scientist and a desperate father. How can I plead any harder? What will it take? What can my colleagues and I do to stop this catastrophe unfolding now all around us with such excruciating clarity?
Analysis: The third part of the panel’s report makes clear a century of rising emissions must end before 2025.
Thirty months: that is the very short time the world now has for global greenhouse gas emissions to finally start to fall. If not, we will miss the chance to avoid the worst impacts of the climate crisis.
The conclusion of the world’s scientists, collated by the Intergovernmental Panel on Climate Change and approved by all the world’s governments, says this reversal requires “immediate and deep” cuts in emissions everywhere.
The language of the third part of the IPCC’s report is less dramatic than the first two, which placed “unequivocal” blame on us for putting a “livable future” in grave peril. Rather than plainly stating the scale of the climate emergency, the new assessment spells out what needs to be done. Its text was therefore haggled over furiously by those states with much to lose.
The world has its best chance yet to reduce greenhouse gas emissions quickly, but hard and fast cuts are needed across all sectors and nations to hold warming to safe levels, the global authority on climate change says.
The Intergovernmental Panel on Climate Change (IPCC) report, released today, says opportunities to affordably cut global emissions have risen sharply since the last assessment of this kind in 2014. But the need to act has also become far more urgent.
The report is the definitive assessment of how well the world is doing in finding solutions to rising temperatures. We each contributed expertise to the report.
Here, we explain key aspects of the findings and what it means for the world, including Australia.
The goal of holding global warming to 1.5 degrees is no longer likely to be achieved, the latest report of the United Nations chief climate body says, though scientists still believe warming may be stabilised and returned under the Paris Agreement’s more ambitious warming target after a period of “overshoot”.
The report by the Intergovernmental Panel on Climate Change (IPCC), published early on Tuesday morning Australian time, was evidence of a damning “litany of broken promises” and a “file of shame”, the UN Secretary General Antonio Guterres said in a speech after the release of the report.
Mr Guterres, whose language on climate has become increasingly strong since the lead-up to the COP26 climate talks last year, catalogued the empty pledges that put humanity “firmly on track towards an unlivable world”.
He said governments and companies had lied to people about their commitments to reducing emissions, and that though the world needed to see a 45 per cent reduction in emissions by the end of the decade the world was on track for a 14 per cent increase.
Large-scale deployment of carbon dioxide removal (CDR) methods is now “unavoidable” if the world is to reach net-zero greenhouse gas emissions, according to this week’s report by the Intergovernmental Panel on Climate Change (IPCC).
The report, released on Monday, finds that in addition to rapid and deep reductions in greenhouse emissions, CO₂ removal is “an essential element of scenarios that limit warming to 1.5℃ or likely below 2℃ by 2100”.
CDR refers to a suite of activities that lower the concentration of CO₂ in the atmosphere. This is done by removing CO₂ molecules and storing the carbon in plants, trees, soil, geological reservoirs, ocean reservoirs or products derived from CO₂.
As the IPCC notes, each mechanism is complex, and has advantages and pitfalls. Much work is needed to ensure CDR projects are rolled out responsibly.
Limiting global warming to 1.5C or 2C would mean “rapid and deep” emissions reductions in “all sectors” of the global economy, says the latest report from the United Nations’ Intergovernmental Panel on Climate Change (IPCC).
Instead, emissions have continued to rise – albeit at a slowing rate – and it will be “impossible” to stay below 1.5C with “no or limited overshoot” without stronger climate action this decade, says the new document, which forms part of the IPCC’s sixth assessment report (AR6).
It outlines how these emissions cuts could be achieved, including “substantial” reductions in fossil fuel use, energy efficiency, electrification, the rapid uptake of low-emission energy sources – particularly renewables – and the use of alternative energy carriers, such as hydrogen.
The new UN report shows the world is not on track to hold the global temperature rise to 1.5 degrees, the more ambitious Paris Agreement target, and that the window to achieving the goal is closing fast.
One of its lead authors, Australian National University Professor Frank Jotzo, says it may no longer be plausible that the world can make the necessary immediate global reduction in emissions.
But the report also presents a range of solutions that, if applied immediately, could limit global warming, some of which have not been part of previous versions.
What do we know about the LNP’s concerns and abilities to mitigate the climate crisis?
As noted in my previous post, many communities are already well prepared to switch from fossil to renewable energy sources as soon as the supply and distribution issues can be resolved. Given that governments supposedly exist to protect and keep their citizens safe from external threats (i.e., global warming) in this case) we should be able to expect that that they would be promoting and facilitating the growth and spread of renewable energy technologies. But, at least in the case of Australian federal and some state governments, they are dong precisely the opposite: denying the science, and blocking and humbugging efforts to research, develop, promote, and roll out renewable technologies across all of our communities.
We have to replace the COALition Government in Parliament with people we can trust to put action on climate change as their first priority before we can have any hope that the government will do its job to facilitate and support effective action to stop global warming and mitigate its effects. Not only do we need to replace Capt Humbug and his troop of fossil fuel puppets, but the clean-out should also include micro-party members such as mining multi-billionaire Clive Palmer’s one-man fake news bureau Craig Kelly, and Pauline Hanson’s anti-science nut Malcolm Roberts.
If you doubt my interpretation, let the fossil fuel industry puppets and humbuggers tell you in their own words how hard they are working to keep growing their patrons’ greenhouse gas emitting industries in the face of the oncoming climate catastrophe.
Prime Minister Scott Morrison says he is supportive of Australia’s fossil fuel industry – and particularly coal, which he… says will be around for “decades to come”. “When it comes to the coal industry, it’s worth $35 billion to us every year in exports, and that’s money Australia needs to grow our economy,” Mr Morrison said. “What you need in today’s energy economy is you need to continue to run your coal-fired power stations for as long as you possibly can and that is our policy … we want them to run as long as they possibly can.” Coal-fired power stations will continue to run to back up renewable power sources, although Mr Morrison said gas would play a larger role in the energy mix in years to come. Mr Morrison added that building a new coal-fired power station would be difficult because of the state government planning powers, which would “probably never allow them to do it”.

See also ‘We will keep mining’, says Australian prime minister Scott Morrison about the future of coal.
If that wasn’t enough, here’s a choice of some of Scotty’s thinking about stopping our slide down the slope to runaway global warming and possible near-term extinction:
We need to turn away from the the road to hothouse hell, and we won’t do this by continuing with the kind of business as usual Scotty from Maketing and his fossil fuel puppets are spruiking!
It seems to taken the clear thinking of Greta Thunberg, a 16 year-old girl who concluded school was pointless as long as humans continued their blind ‘business as usual’ rush towards extinction.
Listen to Greta’s speech live at the World Economic forum in Davos 2019. Except for her reliance on the IPCC’s overoptimistic emissions budget, everything she says is spot on that even she, as a child, can understand the alternatives and what has to happen.
In other words, wake up! smell the smoke! see the grimly frightful reality, and fight the fire that is burning up our only planet so we can give our offspring a hopeful future. This is the only issue that matters. Even the IPCC’s hyperconservative Sixth Assessment WG2 Report that looks at climate change’s global and regional impacts on ecosystems, biodiversity, and human communities makes it clear we are headed for climate catastrophe if we don’t stop the warming process.
Scott Morrison and his troop of wooden-headed puppets are doing essentially nothing to organize effective action against the warming. In fact all they doing is rearranging the furniture in the burning house to be incinerated along with anything and everyone we may care about.
In Greta’s words, “even a small child can understand [this]”. People hope for their children’s futures. She doesn’t want your hopium. She wants you to rationally panic enough to wake up, pay attention to reality, and fight the fire…. so our offspring can have some hope for their future.

Give the children a future worth running towards rather than misery and probable death in the collapsing shambles of global mass extinction along the road to Hothouse Hell
