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.

Residential heat pump produces water up to 75 C: Scientists in Spain have developed a new heat pump that can produce 6.49 kWh of heat for each kilowatt-hour of power it consumes. The device could generate hot water at a temperature of up to 75 C.
Researchers from the Polytechnic University of Valencia in Spain and heating specialist Saunier Duval, a unit of Germany-based Vaillant Group, have developed a new residential heat pump based on natural refrigerants.
The device uses propane as a refrigerant, which allows for high energy efficiency, while keeping carbon dioxide emissions to almost zero.
“Our heat pump can heat homes completely environmentally friendly, without emitting carbon dioxide into the atmosphere. In addition, its high-efficiency energy allows it to be classified as renewable energy, by pumping energy from the environment”, said researcher José Gonzalvez.

Saudi Arabia, India, China, (Australia) and a few other countries have sought to make changes that would weaken the final warnings.

Saudi Arabia, India, China and a few other countries have sought to make changes that would weaken the final warnings, the Observer understands. Some governments are anxious to avoid policy advice such as cutting subsidies to fossil fuels, even though these are widely espoused by leading authorities.This process of refinement – which has also been a complaint in the previous chapters of the IPCC assessment – is defended by some, as producing a document that all governments must “own”, as they have all had input. But many scientists are growing increasingly f
rustrated, as it produces a conservative and sometimes watered down document that many feel does not reflect the urgency and shocking nature of the threat.

Following up on my comprehensive post, The Guardian succinctly explains why the 3 parts of the complete AR6 need to be considered by everyone.

The Intergovernmental Panel on Climate Change (IPCC), made up of the world’s leading climate scientists, has now published all three sections of its landmark comprehensive review of climate science.
…
Yet the picture could already be even worse than the IPCC has presented. The IPCC data took in research papers published from 2014 up to last year, but since then the world has experienced even more extreme weather. The IPCC reports are regarded as cautious and conservative by many scientists, and the summary for policymakers that sets out the key messages of each working group are subject to inputs from governments that some regard as watering down.
The IPCC has warned that if we don’t stop and reverse global warming now it will soon be too late to avoid climate catastrophe and suffering.

Latest IPCC report offers key lessons for Australia but is anyone listening? The climate authority has warned it is now or never to cut emissions but will MPs on the campaign trail heed its warning?
Perhaps the message was too familiar. With the unofficial election campaign under way, and the prime minister mired in escalating allegations of bullying and duplicity, a major report by the Intergovernmental Panel on Climate Change – the world’s most respected climate science body – quickly disappeared from the Australian news cycle this week.
…
Headlines told part of the story: it was “now or never” if the world was to limit global heating to 1.5C above pre-industrial levels. The report suggests that threshold is already practically out of reach without using technology to suck carbon dioxide from the sky. Keeping heating below 2C, which would trigger damage several magnitudes worse than 1.5C, will require an “abrupt acceleration” of effort after 2030.

Population can decline by up to 90% after peaking; according to Frank, such a civilization “might well just descend into chaos.” Sustainability: Both the world population and average surface temperature rise and then level off. This scenario shows that civilizations can be stable in the long term. Collapse without resource change: A civilization makes no attempt to switch to less GHG-intensive energy and collapses due to runaway climate change, possibly going extinct. Collapse with resource change: A civilization transitions to less GHG-neutral energy, but collapses anyway due to triggering a tipping point in the climate system. / 3-01-2021 by LaundryPizza03 – Own work; adapted from a figure in Billings, 2018. / via Wikimedia Commons.

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.

On Wednesday, I was arrested for locking myself onto an entrance to the JP Morgan Chase building in downtown LA. I can’t stand by – and nor should you.
“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”. 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 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.

Existing fossil energy grids were not planned to manage and distribute renewable energy and require either $$$ re-engineering or new thinking
The approved “Summary for Policy Makers” that begins the third part of the IPCC’s (Intergovernmental Panel on Climate Change) 6th Assessment Report, was issued late yesterday after receiving political sign offs after considerable discussion with sponsoring governments. Despite attempts by several governments including Australia’s, to deny or downplay aspects of the report, even this rendition of the scientific findings forecasts an extremely dire future from continued global warming if it is not stopped and reversed below the 1.5 °C level. Fossil fuel burning must stop! (see video).
“It’s now or never, if we want to limit global warming to 1.5C,” said Prof Jim Skea, a co-chair of the report. “Without immediate and deep emissions reductions across all sectors, it will be impossible.”
The implication for the biggest culprit, fossil fuels, is clear: it’s over. The IPCC states that existing and currently planned fossil fuel projects are already more than the climate can handle. More projects will lock in even greater emissions and our journey to climate hell.
With the major project still stalled, and aware of difficulties incorporating big renewable energy generators into the fossil energy grid, the Macedon Ranges community group recently won state government funding for a feasibility study and community engagement program to implement energy storage and batteries at the community level. This project is detailed in the webinar video: “What is a neighbourhood battery and why should I care?“. Even without the local energy farm, the ability to localize and manage energy storage at the community level should considerably reduce the problems anticipated from incorporating renewable energy sources into the fossil electricity grid. This offers a way to facilitate the generation and use of renewable energy at the neighborhood level while reducing peak demands on the fossil network.
Our featured article from the ABC explores this ‘neighbourhood battery option’ in some detail:
Virtual Power Plants versus community batteries
The most effective scale, size, and location
Community battery program initiatives by local community groups and councils.
Lack of trust in retailers, long identified as a problem in Australia’s energy market, is highlighted as a barrier to the adoption of commercially run community battery programs.

What does this all tell us about our governments’ concerns and abilities to solve the climate crisis?
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.

Temperatures across the Arctic are increasing two to four times faster than the global average. The dramatic consequences that are already apparent include reduction of sea-ice cover, accelerating loss of land ice from glaciers and the Greenland Ice Sheet, proliferating wildfires, and—the topic of this panel—ongoing heating and thawing of the permafrost that underlies most of the land area of the Arctic and sub-Arctic regions across the globe. Permafrost thaw is a direct threat to buildings, roads, and pipelines, and it can greatly accelerate erosion along rivers and coastlines with severe consequences for communities located there. But an impact with much wider consequences is the release of carbon dioxide and methane by the decomposition of previously frozen organic matter, affecting the rate of growth of global warming and all of its impacts everywhere. (There is estimated to be something like 2.5 times as much carbon in the as in the entire global atmosphere; the key question is how fast it will come out.) The panelists, leading Arctic experts all, explain the complex science of thawing permafrost and elucidate the implications both regionally and globally.
Editors note: I have often mentioned the potential risk of rapid permafrost thawing serving as a source of powerful positive feedback on global warming from the abrupt emissions of greenhouse gases. The emissions include methane, which has a global warming potential more than 80 x that of CO. The video runs for almost 1½ hours. However, if you want to understand how science works in what are relatively conservative approaches and whether the risks that concern us in the Vote Climate One group are real, the whole video should be well worth watching.
In this pay particular attention to what is left out of the predictive models for future growth of emissions. The actual reality is likely to be even worse.
Finally, a lot of the discussion is based on the idea still common in 2020, that there is some kind of ’emissions budget’ that allows time to stop anthropogenic emissions. With more data, e.g., from the still conservative IPCC Sixth Assessment Report there is much less mention that there is no ‘safe’ emissions budget. Action to slow and reverse global warming is urgent! To be effective this will need global mobilization with cooperation at government levels as well as involving people. Here, our government in Australia has been quite hostile to any kind of action on global warming because of their apparently rusted-on allegiance to the fossil fuel industry and super-wealthy special interests associated with it.
In Scotty’s own words in one of his pet mediums – something to think about:
Prime Minister Scott Morrison says he supports 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.
What can/must we do about this dreadful government and even worse situation?
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 take the clear thinking of Greta Thunberg, a 16 year-old autistic 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 they have expended considerable effort to deny the science, punish the institutions doing the science, misrepresent the facts, and try to divert interest to anything else but action on climate change. Beyond this they are continuing to support and subsidize continued expansion of the fossil fuel industry. Basically, all they doing is throwing coal on the fire and 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.
Our young ones are walking into an unknown future. Give them hope and not the Ukraine.
