Some of the fires are resurging from overwintering remnants of last year’s unprecedented holocaust in the boreal forests. This is assisted by continuing droughts, increasing temperatures, and minimal snowfallls. Ft McMurray, that was partially cremated in 2018 with $ billions in damage costs and the commercial and residential center of the tar sands (dirty!) oil producing district, is again being evacuated under threat from a repeat by another monster blaze. Other population centers are also under threat.
Clouds of smoke, toxic aerosols, and greenhouse gases are already spreading into the higher Arctic and over the northern United States.
It’s likely that the Russian taiga (boreal) forests and tundra are also beginning to burn as they did in 2019 – 2021 (see Portents for the Future – 2020 Wildfires on the Siberian Permafrost). This alone will keep temperatures rising unless we can reduce the constant input of solar energy enough so Earth can again radiate (mostly long wavelengths of IR) more energy than it receives. If we don’t do this soon, Earths ecosystems will be collapsing at a steeply accelerating rate over a few more decades until no accessible carbon is left in the geosphere – i.e., after most life save a few preadapted extremophiles – are left.
To stop the warming we will have to join in total global mobilization to geoengineer zero new emissions, draw down a substantial fraction of the presently existing GHGs to open the atmospheric windows for more IR emissions to escape Earth, and to increase Earth’s reflectivity enough to significantly reduce the absorption of solar energy. Led by America, the West was able to achieve this kind of mobilization to win WWII in little more than 4 years from the start of America’s joining the fray at the end of 1941. Such mobilizations need to be managed and led by governments, however, most current governments of the world (including Australia) are controlled by puppet-masters in the fossil fuel and related industries who are actively blocking any attempts to initiate effective action.
For our species to have any chance in any kind of sustaining biosphere, our mobilization must begin with replacing fossil fuel puppets in our ‘majority’ controlled governments with climate aware and progressive Greens and community independents who understand the issues and work for their constituents rather than their (often non-citizen) puppet masters.

If we don’t reverse the climate system’s growing energy imbalance it will soon drive us over the lethal fall into global mass extinction
ALL the global climate indicators are at or near all-time records so extreme that by September last year staid climate professionals have called the readings “gobsmackingly bananas.” — a phrase that is now in common usage in the climate science community. To some, the readings spell doom is nigh. But, here, i’m with the Guardian’s Fiona Katsaukas and her friend in the green shirt.
These gobsmacking records bear witness that Earth’s climate system has shifted into a new kind of rapidly evolving climate regime that is not encompassed or anticipated by existing climate forecasting models (at least not before 2050…). Every month since September has set new, still more extreme records.ALL the global climate indicators are at or near all-time records so extreme that by September last year staid climate professionals have called the readings “gobsmackingly bananas.” — a phrase that is now in common usage in the climate science community. These records bear witness that Earth’s climate system has shifted into a new kind of rapidly evolving climate regime that is not encompassed or anticipated by existing climate forecasting models (at least not before 2050…). Every month since September has set new, still more extreme records.
In 1985, the renowned planetary systems scientist and cosmologist (also one of the best communicators of hard science to the public the world has known), Karl Sagan addressed the U.S. Senate Environment and Public Works Subcommittee on Hazardous Wastes and Toxic Substances hearing on the greenhouse effect to explain the then scientific understanding of global warming. The 17 minute video on YouTube of his speech is extracted here by C-SPAN. C-SPAN also has the full 2 hour, 24 min video of the hearing. I mention this to triply underline the fact that the science of global warming and its consequences was already clearly understood four decades ago. The only fault in Sagan’s exposition is that the predicted dire consequences are happening sooner than he anticipated. This is still a common problem in climate science today where most climatologists trained in maths or physics still fail to appreciate the importance of fundamental non-linearity and chaos of complex dynamical systems like climate. The existential emergency Sagan predicted for the latter half of the 21st Century has already started now.
Because the [greenhouse] effects occupy more than a human generation there is a tendency to say that they are not our problem. Of course, then nobody’s problem, not on my tour of duty, not on my term of office… It’s something for the next century. Let the next century worry about it. But the problem is that the greenhouse effect is one of them which have long time constants. If you don’t worry about it now, it’s too late later on; and so in this issue, as in so many other issues, we are passing on extremely grave problems for our children when the time to solve the problems if they can be solved at all is now.
Carl Sagan, 1985, transcribed from C-SPAN video [2:30-3:15]
Today’s screams heard now from continually breaking climate records are the realities anticipated 39 years ago in this address;
In my “Feb. 2024 climate extremes” report (published March 12) I review the records as they were being broken in the February peak of the global climate cycle. I am currently trying to finish an update on the first anniversary of setting continuous daily record high global sea surface temperatures. detailing the piling up energy flows through the climate system (as described by Sagan) from the time solar energy is absorbed in the climate system and is eventually emitted back to space in the form of infrared emissions leaving the Earth. I have posted the current state of the first part, “Considering the first anniversary of a new climate regime — Accelerating down the road to extinction in Earth’s Hothouse Hell?” in the Google Docs format (that everyone should be able to read). Completing this is difficult because many indicators are literally breaking records faster than I can write about them. The most important of these regularly breaking records is the daily average sea surface temperature (SST), which is the first place excess solar energy piles up in the climate system. On 9 May SST is still more than 0.1 °C above 2023’s 9 May record – the 423 day of continuous daily records. The graph below focuses mainly on the part of the years where this year’s record is on top of last year’s. Note that Sagan also predicted rapidly rising sea levels. Today’s Washington Post describes how the southeastern US is currently being affected by this rise (probably because hot water is being backed up in the slowing Gulf Stream).
However, so people can see the evidence that is driving us here in @VoteClimateOne to do what we can to fight the emergency, I have also been posting to X-Twitter, and I include a couple of samples here:
If not this year, the next 1 or 2 years will see Kim Stanley Robinson's million-death heat wave: The Ministry for the Future (https://t.co/6ifnrqiIzP). If we ignore this emergency and fail to totally mobilize to reverse Earth's energy imbalance before society collapses, we'll… https://t.co/4eKQiB9Egypic.twitter.com/TBAblGHNtf
Copernicus offers no good news. Their news is amplified by a small sample from other sources. Global mass extinction (including us) is virtually certain unless we reverse the energy imbalance. However, given that humans created the climate crisis with 19th-century tech, we should… https://t.co/GxBU3LXd67pic.twitter.com/u9xdLI8iHI
As ever increasing numbers of climate scientists and aware commentators are crying out that it is time to sound the emergency alarms and urgently mobilize to fight the global emergency while there is still some chance that with our far greater knowledge and more powerful science than Sagan knew about (he suggested that by now it would be too late to stop the inevitable catastrophic end), it might still be possible for us reverse the solar energy imbalance that is rapidly driving our planet’s temperatures towards runaway feedbacks that will ensure global mass extinction is truly under way before the end of the 21st Century.
Another new fact in today’s in box hit me in the face. The record high rate of increase in CO₂ causing a majority the backup of the solar energy that is cooking us is still ACCELERATING UPWARDS at a record high RATE OF ACCELERATION. To me this suggests that runaway warming driven by positive feedbacks with temperature has well and truly started. ‘Natural’ emissions are already coming out of the ground, permafrost, wetlands, forests, and oceans faster than we are reducing fossil fuel emissions.
I’m like the girl in the green shirt in Katsaukas’s cartoon. I think it is well and truly time to sound all the emergency alarms and start total global mobilization to fight the crisis. My knowledge and experience tell me that if enough of us are willing to accept the reality of the danger and work together as a disciplined emergency force, we have sufficient knowledge and technological prowess to turn off the road to extinction and find some way to sustain at least some of the living world we know today.
Born in 1939, I’m old enough to remember living in a blacked out house in Los Angeles, and then the successful ending of WWII in 1945 little more than 4 years after America mobilized and joined the war at the end of 1941. At least in 1941-42 Americans managed the kind of mobilization we need today. I think we might still be able to defeat the runaway warming enemy if we start soon enough and fight hard enough to find a place in a still sustainable biosphere. On the other hand, I’m as close to certain that if continue to avoid looking at the grim and (for some) terrifying reality in hopes of continuing with business as usual, we will be burning up in the midst of the worst global mass extinction (i.e., even worse than the End Permian extinction ~ 250 million years ago).
As well as learning about global mass extinction when I learned to read from my father’s university textbooks in geology and paleontology, I grew up in navy towns started university as a pre-engineering student before changing my major to zoology and earning my PhD in evolutionary biology as well as teaching a variety of genetic, organismic, systems and population biology courses. I also worked professionally as a radiation ecologist and for the last 17 years before ‘retiring’ I designed a variety of documentation and knowledge management systems for Australia’s then largest defense engineering company. There, my systems helped ensure the on-time, on-budget completion of the ~7 billion $AU ANZAC Ship Project. (This is one of the very few large defense projects in world history that did not end up years overdue and billions of dollars of cost overruns, thanks in good part to systems I designed specifically to solve the kinds of management and engineering change issues that defeat most large defense projects). Finally in retirement I have spent some 15 years researching and writing on the coevolution of humans and our technologies prior to deciding that doing what I could to address the climate crisis was far more important than finishing a book for a society doing nothing to save itself from extinction.
In @VoteClimateOne.org we have thought a lot about what we can do to help the mobilization. It is clear that most governments in the world today are being run by fools, useful idiots, or puppets owned and led by already insanely rich fossil fuel and other special interests will do or say almost anything to gather more wealth. Political party discipline means that a majority government can be controlled by a handful of ‘strong’ party members and functionaries in leadership roles. For example, in Australia, the supposedly ‘climate friendly’ Labor majority government has just demonstrated its fealty to its puppet masters over effective climate action.
@VoteClimateOne.org has a two-pronged approach to try to change governments into supporters and even leaders of the climate emergency mobilization effort.
Given how urgent the need for action is, we hope to convince the puppets and other blockers that climate action is far more important and urgent than whatever benefits they gain from catering to the desires of their patrons and masters. However, this will take a massive effort – much more than just supplying truthful information that is easily ignored or actively denied. Minds might be changed if enough people piled on each and every recalcitrant parliamentarian – but this would take the concerted action of a large number of climate and environment action groups that has to this point not been forthcoming.
The other prong in the spear, is to actually replace enough of the recalcitrant parliamentarians with progressive community representatives or small party members who truly understand and accept the crisis and the need for action; and who are willing to put in the effort to get elected — to prevent either major party from forming a majority government. Not only will there be more sensible and effective parliamentarians, but any party forming government will have to listen to and compromise with genuine community representatives to do anything, even if this requires them to mobilize an effective climate action.
Our home page, ACT NOW, and TRAFFIC LIGHT VOTING explain how this all works, and provides examples of how we have addressed past elections. Hopefully all voters will have the chance to see and think about what these pages have to offer, and inform their voting decisions with the climate crisis in mind. As elections approach, CLIMATE SENTINEL NEWS will be providing frequent updates on the state of the climate and relevant political news.
Our grandchildren tell us all to “vote climate one” so they can have a happy future rather than the descent into Earth’s hothouse hell (like Sagan and most climate scientists until the last few months, the authors of the referenced paper have overestimated just how much time we have left for effective action).
WE MUST BEGIN ACTION NOW!

“The Copernicus report said if December records a similar temperature anomaly to November, the average temperature for 2023 will be 1.48 degrees above the pre-industrial reference level.”
Chances are that if December is significantly hotter than November, Earth will break the 1.5 °C ‘barrier’ this year, that COP 28 is supposedly working towards stopping…… See the featured image here from the ABC article (“Global temperatures in 2023 are tracking well above every other year on record. / Supplied: ERA5/C3S/ECMWF)”
ABC gives the facts below. Climate Sentinel News has spent many months reporting how continued warming will result in near term human extinction (i.e., possibly within the currently expected lifetimes of humans living today). We suggest that you review these warnings and take them very seriously indeed, and work collectively to force our governments to immediately force the fossil fuel industry to stop carbon emissions of all kinds.
Yes, we will probably need to implement energy rationing while sustainable resources are ramped up. However, this is better than allowing Fossil Fuel control our governments and condemn Earth life to global mass extinction.
Globally averaged surface air temperature anomalies relative to 1991–2020 for each November from 1940 to 2023. (ERA5/C3S/ECMWF via ABC)
Scientists have confirmed 2023 will be the hottest year on record, with the official declaration from climate change service Copernicus, run by the EU, made with a month to spare.
The startling heat records come as large parts of Australia are set to endure heatwave conditions, with temperatures expected to reach over 40 degrees in some places.
The world can’t stop breaking heat records this year, with each month since June becoming the warmest on record.
The Copernicus data confirmed the trend, with the warmest November on record globally hitting 1.75 degrees above the 1850–1900 pre-industrial reference period….
Storm Daniel’s inundation of Greece’s agriculture (when complete records for gauges knocked off line by flooding were retrieved later, it was reported that Zagora actually received more than a meter of rain from the storm);
and then a couple of days later, the same storm Daniel caused an apocalyptic flash flood that completely erased the heart of the Libyan city of Derna, along with perhaps 13,000 of its ~130,000 inhabitants (the actual counts will never be known because of incessant warfare between the various heavily armed fundamentalist Islamic sects and warlords).
Even worse for me personally, has been the fact that people in general paid virtually no attention to or showed any understanding of the significance of these and many other comparably extreme climate events and situations requiring emergency action.
Also, more specifically, the Derna situation was so extreme that I could not understand how a single overnight flash flood could comprehensively erase the fundamental infrastructure and fabric of a modern city — even given the fact that two earth-fill embankment dams were also almost completely erased in the process. Most people have blamed the cataclysm on the failed dams, making it easy to gloss over the fact that the dams were casualties not causes. Thus, I have felt compelled to spend my time forensically studying the vast array of imagery of the Cyrenaican region of Libya where Derna is located before, during, and after the flood(at resolutions down to 25-50 cm), press photography, drones, and ‘witness’ reports on social media to determine what actually happened.
Briefly summarizing what I have determined so far:
Derna was built on a relatively flat fossil delta whose seaward edge is 7-8 m above sea level, such that all runoff falls over sea-cliffs to reach the Mediterranean sea. The imagery of damage to surviving buildings more than 200 m from the banks of the normally dry wadi running through the city convincingly shows major flood damage up to the 3rd or even 4th floors. On the evening of Sept. 10 when the rain started the wadi reached the ocean via a 6 m drop at the delta’s edge. On Sept. 11 as the flash flooding was receding, the now uniformly sloping wadi floor reached sea level ~ 450 meters inland from where its spout had been the night before.
Making sense of this data has not left me time to continue reporting disasters that have little historical context and no one seems interested in reading about unless they are personally affected by them.
However, Derna’s long history tracing back to its settlement by Greeks around the middle of the 7th Century BC, and some strong geological markers I now understand give some very solid evidence regarding the extreme nature of the recent event. Also, around 650 AD three of the Prophet Mohammad’s followers who were martyred along with ~ 67 fighters in the First Islamic Conquest of North Africa were buried on the bank of Wadi Derna. Their graves have been marked and venerated since then and memorialized with proper shrines and then eventually with Derna’s largest mosque. Overnight on Sept 11, the shrines, the graves, and “meters” of soil below where the graves had been were erased in the cataclysm. That’s evidence that Derna never had a comparable flood in a millennium and a half.
The geological evidence is orders of magnitude more extreme: Deltas form at sea level. The last time the sea level was 7-8 m higher to enable the formation of the present deltas was during MIS 5e in the Eemian era of the Last Interglacial Maximum around 123,000 (or less likely 118,000) years ago. The geological history of Cyrenaica shows that this area has been very stable over this period, suggesting that the three fossil deltas (including Derna’s) found along this part of the Cyrenaican coast could not have been formed any more recently than 118,000 years ago! Until Sept 11, the wadi’s that built the deltas reached the sea via spouts 5-7 m above sea level. As is the case for Wadi Derna, the other two wadis also eroded beds beds to reach sea level significantly inland from the elevated spouts that existed the day before. This is rock solid evidence that the last time weather was this extreme was more than 100,000 years ago, i.e., 100 millenniums ago when the deltas were built!
This work should be published before the year is done, when we’ll be gearing up for more elections.
In any event, if we don’t stop and reverse the still accelerating global warming, we can expect even worse to come as air and ocean temperatures continue to rise to extremes not seen for millions of years.
The farce of COP28 shows that the only way this reversal will happen is if concerned citizens can take back control of our governments from the fossil fuel special interests. To do this a majority of people must convince or replace their elected representatives to actually work for their survival rather than working to feed the greedy special interests.
Dr Andrew (“Twiggy”) Forrest tells international business and political forum the factual reality that “Business will kill your children!”
When I started this essay, Renew Economy, whose article is linked below, was one of the few mentions I found in the press or social media of the unique event where any self-made billionaire, let alone an Australian, stated simply and with honesty that his business kills our children and puts human survival at risk. He asks for help in making him, his industry, and business in general to stop carbon emissions. Simultaneously, and blissfully unaware of what Andrew Forrest was saying, a collaboration of climate and environmental action groups was organizing an emergency meeting, #SteppingUpTogether, for Melbourne Town Hall to crystallize a coalition of (hopefully ALL) such groups to provide precisely the kind of help Forrest was asking for.
Both Forrest and the people at Melbourne Town Hall accept that it may already be too late to avoid the existential climate catastrophe.
However, by working together, he and we may actually be able to defeat global warming, and work our way off the highway to Earth’s Hothouse Hell to find a probably rough and narrow road to stewardship of a habitable world with a sustainable future.
“Business will kill your children:” Was Andrew Forrest’s climate speech really that “loopy”?
It was the sort of speech you [would be lucky to] hear from climate scientists and climate protesters; a presentation stunning in its simplicity and series of one liners.
“It is business that will kill your children,” Forrest declared. “It is the beginning of the end.
At $US 21.7 Bn, Forbes Australia’s Richest in March placed Andrew Forrest second (after Gina Rinehart at $US 30.6 Bn) amongst the motley crew of billionaire miners, tech sector high flyers, and property developers, most of whom seem to be more concerned to build even more personal wealth than they already have. To many in the climate and environmental action movement, these billionaire business people are the class enemy. It is their industrial businesses that are largely responsible for driving Earth’s climate system into what now looks like runaway warming. Warming that will lead to climate catastrophe and probable extinction at the end of the downhill highway to Earth’s Hothouse Hell.
Yet, Forrest’s 24 minute speech, delivered Aug 30 in Perth at the Boao Forum Asia (29-31 Aug — sponsored by China) and linked above, is the complete antithesis of what you would expect to hear from one of the self-confessed perpetrators of the currently accelerating climate catastrophe threatening us.
Amongst other things, the speech: ● confesses and condemns what business has done to put human survival at real risk; ● gives a meticulously and gorily detailed description of one of many ways that the business triggered climate catastrophe will reap human lives along he road to extinction; ● expresses Forrest’s promise and “steely determination” that he and ALL of his industries are committed to reach absolute zero carbon emissions by 2030 [I’ll have more to say about this promise below] — both to stop emissions from his business, and to show the world that it can and must be done; ● asks that China, India, and the USA step up together to legislate and subsidize doing whatever it takes to achieve what he is showing can be done; and, finally, but by no means least, ● Forrest begs citizens and consumers around the world to make governments and businesses do these things:
This is what I’d like to put out to you as members of the Boao Forum.
This is not my idea, or any single person’s idea. If this is our idea in the Boao Forum, this is what I ask you to consider during the course of this day and decide:
Do we want a member’s resolution of our forum to ask that discussions proceed at the G20?
That intention to proceed with law happens at APEC and that the business people of the world gather BOAO Forum for Asia next year and work out how to do it.
Business people, if we are not fighting with our own governments, [we] can leave this [meeting] and make it happen….
and that’s what I’m asking [for], a simple agreement led by business.
Fast! …..Because it’s business.
I need you tonight….
It’s business which is causing global warming….
It’s business which will kill your children.
It’s business which is responsible for lethal humidity.
But it’s policies which guide business!
YOU MUST HOLD US TO ACCOUNT!
Don’t let us with our clever advertising blame
You — the consumer; or
You — the public or individual…..
That’s rubbish.
Business guided by government will either destroy or save this planet.
To understand greatness and gravitas of Forrest’s address and its implications for all humanity takes your patient and careful attention to his actual words and your awareness of several contexts surrounding the lead up to the conference. Of course, in the case of Australian media, his content and intent were so incongruous that it took two or three days into September before there were many reports at all.
Murdoch and the financial press (often the same) responded to Forrest’s attack on fossil fuel and gory details about how heat kills people by claiming that he must have lost the plot to ever increase his personal wealth due to a brain seizure or having gone troppo — bad news for his shareholders. Even usually progressive and climate action friendly press such as the Saturday Paper, Crikey, and the Guardian seem to have missed the point. However, in the last few days more articles, accepting that the speech was actually important, have given more thoughtful attention to its actual content (e.g., see ‘Twiggy’ Forrest: Climate messiah or billionaire opportunist?, from Sept. 13). But, even here, commentators seem to have real difficulties seeing past what they assume must be Forrest’s overwhelming drive to become even richer.
Personally, I think these commentaries trivialize and miss the major thrust. This man from the bush is staking his fortune, career, family — and everything else…. To crystallize a critical transition:
From: corporate business as usual — working for immediate profits that are far more important than even human survival in the face of the growing climate catastrophe.
To: business working to build a healthy society that can sustain itself into the foreseeable future.
What has Andrew Forest actually said?
In my diverse careers in science, teaching and corporate knowledge management, I learned that speech has a low bandwidth for communicating detailed facts and knowledge. You have to listen to strings of words before their meaning and import are clear. As Walter J Ong observed in his classic work, Orality and Literacy: The technologizing of the word, speech disappears in the instant of its impact on the ear-drum of the listeners. All that is left are fading impressions in the hearers’ brains that were influenced by all kinds of extraneous perceptual and cognitive issues, to say nothing of preexisting memories and biases. In other words, we often only hear what we expected to hear, not what was actually said, and certainly not everything that was said.
Because, on first listening to the speech, I thought that Forrest had said some very important things. His speech was important enough that I needed to read, and re-read it in a printed transcript. Not only is reading far faster than comprehending the spoken word, but it is much harder to misread than to mishear. And, if you missed something or are unsure what was said, you can re-read the work as many times as it takes. And if there is a video of the speech, you can go back as often as you want hear and see HOW it was said.
The only transcript I could find was YouTube’s totally unparsed and unpunctuated speech-to-text (click the three dots at the end of YouTube’s video menu bar, and select “Show transcript”). In any case, I had to do the parsing, punctuating and formatting of the text myself to be sure I understood it. I had to look at each word, and pick out each thought and sentence in the sequence and then parse out the thoughts on the screen/paper. Where there was any chance of misunderstanding (YouTube’s transcript has some fascinating garbles, e.g., 23 secs, in “Minderoo Tatterang” becomes “military”), I had to go back to the original speech and its various contexts to be sure that the transcript actually recorded the spoken word(s).
The deeper I got, the more impressed I was with the total precision and clarity of Forrest’s expression. Almost without exception, every single word was precisely chosen and placed to unambiguously convey a particular thought. He said exactly what he meant, and totally meant what he spoke.
Forrest must have put a great deal of thought and rehearsal into crafting the talk; and based on the hoarseness of his speaking, he had also been doing a lot of talking (arguing?) in the lead up. By no means was there anything sham or trivial about the talk.
As many of those commenting on the address dimly recognized, this is a pivotal turning point in Forrest’s personal and professional career. This giant of a man who arrived at the 20th Anniversary celebration of his mining company on one of his many 3 story tall dump trucks was once a jackaroo from the WA bush.

Forrest is betting his entire fortune, body, soul, and family on his understanding of Earth’s climate crisis and what he thinks he can do personally and via his business empire to help humanity find a sustainable pathway to an extended future.
I don’t think there is anything particularly messianic about this. Forrest is self-made, he knows his limitations and his very real capabilities. He has assessed that he has the capabilities to be an agent of changes that must happen if humanity is to survive the present climate crisis. “Again, someone has to do it. “And I just think, ‘If not me, then who?’ ” [quote from SMH 2/072022]. And if he hasn’t at least tried…. then emissions from his mining activities have been at least partly responsible for the end of humanity.
Definitely not a messiah, but perhaps a redeemer?….
Forest has placed his bet, turned the roulette wheel, and rolled the ball (the image is from his presentation).
He is helping us, …..so all those of us in the climate and environment action community need to hold him, business and government to account, so the ball falls in the correct slot for all of us to win the “one in fifty chance of 1.5 °C holding”.
Critical Contexts
Andrew Forrest more-or-less grew up in WA, on the Forrest family owned Minderoo Station (when he wasn’t away attending school), a 2,400 km² sheep and cattle station traversed by the Pilbara’s Ashburton River and 95 km E of Exmouth across the Exmouth Gulf.
He may spend more time on corporate jets than on horseback these days, but the fact that he hails from the wide open spaces is an important part of Andrew Forrest’s mystique. He likes to remind us that the red dust of the outback is deep in his pores – that even when he’s sporting a dapper navy suit, his mindset is that of a man in moleskins.
After meeting US President Joe Biden at COP26, the UN climate conference in Glasgow last November, Forrest accepted an invitation to visit the White House to continue the conversation about green energy. Describing how he felt as he entered the West Wing in April, he says: “Ex-jackaroo. Kid from the bush. So fortunate to be able to do this.”
…
Mounting debts had forced Forrest’s father, Don, to sell Minderoo Station in 1998. When the property came back onto the market 11 years later, Forrest sent two bidders to the auction – “just in case one had to go to the toilet or had a heart attack”. He bought it for $12 million and has spent millions more turning the station into a showpiece. He says he does his best thinking there. The place is full of memories, not all of them good.
When Forrest was a boy, just eight years old, he noticed smoke on a distant part of the property. Lighting a fire was the accepted method of sending a distress signal, so he and Don went to investigate. A man had been working on the engine of a bulldozer when it jumped forward and pinned him against a gum tree. He had managed to light a fire but it burned back towards the tree and engulfed him.
“When we got there, we found this charred but breathing body,” says Forrest, who travelled with the man in the back of the Land Rover on the long drive to hospital. “He could just speak and he said, ‘Sing me some nursery rhymes.’ ” Forrest held the man’s hand and sang to him until he died. He tells me during our lunch at Cottesloe that it was this experience, more than any other, that shaped him. From then on, he understood at a visceral level that life was short and not a day should be wasted: “I do tend to treat time as being incredibly precious.”
Time is valuable to Yindjibarndi leader Michael Woodley, too, and he has spent a lot of it slogging his way towards legal recognition of his people’s ownership of land on which Fortescue mines. “Everything is about Andrew Forrest. His image. His brand,” says Woodley, who contends that if Forrest has been able to live a large life, “it’s because of the wealth that he has generated from our country. That’s what money does, right? It turns you into a superstar.”
Immense wealth also gives some people immense power to do things mere mortals can only dream about…., like saving human existence. In 2001 Andrew Forrest and his wife, Nicola, established Minderoo Foundation (named after his boyhood home) with part of their Fortescue wealth to work towards making our shared planet a better and safer place for people to live. As at 20 June, 2023, the Forrests have donated a fifth of their Fortescue shares to the Foundation (about $5 Bn), bringing its total endowment of the Foundation up to about A$7.6 billion).
“As our world faces enormous challenges, we have elected to continue to use our material wealth to help humanity and the environment meet these existential risks,” Dr Andrew Forrest AO said.
“Accumulating wealth should only be a small part of a person. Their contribution to their family and society is way more important. Other skills such as carpentry, farming, the arts, working in construction or for government are equally as important. If you happen to be good at accumulating wealth, then I believe in using that skill for the greater good.
“This is why we will continue to donate our wealth to causes where we can make a sustainable difference.”
Of course, Forrest presumably still controls how those deeded shares are voted. He may have ceded the capital and income they represent, but most likely still controls the power they represent.
Another large tranche of his family wealth is devoted to a private investment group with a very strong social and environmental policy called Tattarang (see also Wikipedia).
The name Tattarang pays tribute to a fiery but caring stallion that was owned by Andrew Forrest’s mother and cherished by all at the Forrest family’s Minderoo Station during the 1950s.
In a joint statement, Andrew and Nicola Forrest said: “The name Tattarang has held a special meaning in our family over many years and was the inspiration to rename our commercial group. For us, Tattarang signifies the unique bond of trust that is formed between a rider and their horse, and the seriousness each party invests in caring for and protecting the other.”
The Forrests said they wanted business to play a greater role in changing the world for the better.
“The way you earn your money will have a greater impact than the way you choose to give it away. Business is critical to improving the world,” added Grace Forrest, Director of Minderoo Foundation and Co-founder of Walk Free.
The Tattarang group entities remain separate from Minderoo Foundation, the philanthropic entity founded by Andrew and Nicola Forrest. As part of the name change, Tattarang has launched a new corporate website: www.tattarang.com.
Dr Andrew Forrest AO is Chairman of Fortescue Metals Group, the publicly listed company he founded in 2003, in which Tattarang Pty Ltd holds a 36 per cent shareholding.
The scale and severity of bushfires in Australia over the summer of 2019-2020 was a clear example of how increased weather volatility due to climate change is already contributing to the intensity and scale of natural disasters.
The time to act is now. Collectively, we must act with all speed and determination to reduce emissions and create pathways to achieve a net-zero emissions global economy. Climate change is already exacerbating environmental degradation and as a society, we must also adapt to protect human health and threatened ecosystems through environmental conservation measures, including effective plastic waste management.
We must act immediately if we are to effectively adapt to the impacts of climate change and to achieve net-zero emissions well before 2050. If we do not act, we risk leaving enormous challenges, and terrestrial and marine ecosystem-wide destruction to our next generation. Tattarang accepts this call to action.
Tattarang has commenced an assessment to estimate the emissions from its investments, activities and operations. This will provide critical data upon which Tattarang can implement a range of actions including the development of science-based emissions reduction targets and emissions avoidance and mitigation projects.
And then, who is this titan of industry and business, who thinks that he can tell us that we are all doomed to oblivion if we don’t stop global warming NOW, while we still might? Forrest has made himself into a genuinely qualified marine scientist, with an earned PhD to prove it. It’s a real thesis, based on real research — done in the midst of building his fortune….
Personally, I grew up on and in the ocean — face to face with a diversity of life far beyond anything that can be experienced on the land. I am an academic scientist. Marine biology was one of my teaching specialties…. It’s a real thesis….
[Eight] years ago, Forrest was hiking in the Kimberley when a ridge gave way and he fell into a large pool. One of his legs shattered from the kneecap down as it wedged in a loop of submerged tree root, trapping him underwater. The pain was excruciating and in wrenching himself free, he mangled the leg further: by the time he struggled to the surface, his foot was facing the wrong way. The accident may not have killed him, as for a few heart-thumping seconds he thought it would, but it changed him.
During his convalescence, as he moved from a wheelchair to crutches and finally back onto his feet, he had time for reflection. He decided to embark on a PhD in marine science, a field that had always fascinated him. For four years, he immersed himself in the study of pelagic ecology and, more broadly, the state of the world’s oceans. “It was there that I really came across the reality of global warming,” he says. By 2019, he was Dr Forrest, eco-warrior.
So far, the continuity of this interest is represented in real estate by the Exmouth Research Lab, a new marine biology lab he had built about 80 km across Exmouth Gulf from Minderoo heartland.
I have parsed and reported what Andrew Forrest spoke to the world at the Boao Forum late in August, and analyzed the contexts from which the words came. What remains to be seen is whether the world will step up and unite to solve the existential crisis so forcefully laid out before us by this remarkable address.
If anyone has any residual doubts about Forrest’s sincerity, he has wagered control of his family and foundations’ fortune on being right (remember the imagery of the roulette wheel), and burned a lot of bridges along the way.
In his interview with 9News, following separation from his wife, Nicola, Andrew Forrest admits he’s hard to live with, and explains the high turnover of Fortescue executives: ‘My way or the highway [to Hothouse Hell]’. Several chosen the highway, and there may well be more. With his transfer of shares into Minderoo Foundation and voluntary settlement with Nicola, 9News reports that this moves Andrew from 2nd to 13th place in AFR’s Rich List (‘Nic and I are lockstep’: Andrew Forrest gives first interview since split from wife Nicola). This suggests he is left with a fortune of between $7.5 and $6.5 bn. Even if you assume that growing his wealth is Andrew’s main concern, he has risked ‘everything’ on his turn of the roulette wheel to decarbonize all of his businesses…..
If anyone can bulldoze his way through to convince our world leaders that they have to prioritize climate action above all else, Andrew Forrest has a better chance of doing it than any other person I can think of: Pope, UN Secretary General, David Attenborough, et al. But to make it stick, he needs coordinated support and cooperation from the bulk of society that I think the world’s climate and environmental action groups represents.
Some afterthoughts
VoteClimateOne.Org recently (9 September) participated in a recent emergency meeting of diverse climate and environmental action groups at Melbourne Town Hall called #SteppingUp Together focusing on how we might work together to advance action on the climate emergency. This was organized in part to begin establishing a structure able to help the (literally) millions of Australians belonging or subscribing to such groups coordinate their individual voices to make businesses and governments change their focus from promoting and subsidizing industries killing our children with carbon emissions to legislating and organizing the fight to stop and turn around global warming.
Although few of us at the #SteppingUpTogether meeting knew of Andrew Forrest’s Boao Address at the time, it stands as a clarion call to to mobilize the global war effort to defeat the existential enemy — global warming. It is no coincidence that the common goal to our diverse approaches is to give consumers and individuals tools to construct a common voice able to hold governments and business to account. We all see and understand the need to actually achieve what Forrest is calling for us to do!
Although the SteppingUp meeting was originally conceived to coordinate demonstrations and actions to convince the Government to stop fossil fuel export developments (especially in the Beetaloo Basin and Darwin areas), the crazy extreme deviations in global climate indicators (documented by Climate Sentinel News posts and in direct mailings to all Australian MPs) made the meeting a lot more urgent, with several important speakers being incorporated only shortly before we met. These last-minute additions included:
Assoc. Prof Mark Diesendorf, UNSW Sydney, was double booked so could not attend in person, but provided us with a couple of videos, focused on his research on how fossil fuel and other special interests have captured “captured” and control governments so they do their bidding rather than working for constituents’ interests. This gives the SteppingUp group a deep understanding of where and how we have to force change before our government will actually begin working in our interests. Diesendorfs’ ideas are fully laid out in his 2023 book (with coauthor Rod Taylor), “The Path to a Sustainable Civilisation: Technological, Socioeconomic and Political Change“. This helps us know our enemies….
Just back from the Northern Territory, Jane Morton, who helped bring Extinction Rebellion to Australia and co-convenor of Darebin Climate Action Now, who in 2016 instigated the first local council in the world to declare the climate emergency gave us a talk on some of her methodology.
Charlotte Gallace, an amazingly poised year 9 student and school council member at Prahran High School, and also a school striker, presented the younger generations’ hopes that we would get our act together and leave her generation with a sustainable future.
SteppingUpTogether organizers had hoped that we could have at least one of the recently elected ‘teal’ community independents join us, but this proved impossible given their workloads while Parliament was sitting (both major parties have been happy to deliberately hobble independents by limiting each to only a single paid staff member).
Given the plethora and importance of these last-minute speakers, and the enthusiasm of our planned speakers to share their tools and ideas for changing the minds of currently ‘captured’ MPs, we had no time left for our planned workshop. However, you can be sure that we are already working towards assembling a user-friendly communications apparatus to share our practical knowledge and for coordinating public and MP-focused campaigns.
Given the urgency aroused by the crazy extreme and still growing indications that we already tipping into a hotter and more rapidly changing climate regime, you can be sure that within a few more weeks SteppingUpTogether attendees (and many other organizations) will be putting together a network facilitating the coordinated and collective involvement in public and MP-targeted campaigns of the millions of members belonging to one or more climate and environmental action groups.
End state capture!
Hold our governments to account: Make them work for Us — The Public…. The Consumers…. The Individuals.
Make the governments change…. Make the governments hold business to account….
Hold governments to account…..
Victoria first, then Australia, and then the world.

Leading up to this September’s extremes

From June to August 2023, a series of extreme weather events exacerbated by climate breakdown caused death and destruction across the globe.
As the world sweltered through the hottest three month spell in human history this summer, extreme weather disasters took more than 18,000 lives, drove at least 150,000 people from their homes, affected hundreds of millions of others and caused billions of dollars of damage.
That is a conservative tally from the most widely covered disasters between early June and early September, which have been compiled in the timeline below as a reminder of how tough this period has been and what might lie ahead.
How much are these extremes costing society. For an idea see the following graphic from Scientific American’s blog. Note: this graphic applies only to the US,
https://www.theguardian.com/environment/2023/aug/28/crazy-off-the-charts-records-has-humanity-finally-broken-the-climate Warning: Data is provided for this article by climate scientists who suffer from the reticence causing academic and institutional scientists to downplay any overly ‘dramatic’ warnings in order to avoid alarming departmental colleagues, administrators, or governments influencing hiring, promotion, financial support for research, etc. Google “scientific reticence” and you will find lots of evidence on how it works.
The current extremely low sea ice will have a range of impacts. Changed ocean stratification and circulation will alter basal melting beneath ice shelves48. Greater coastal exposure will increase coastal erosion and reduce ice-shelf stability49. Changes in dense shelf water production will alter bottom water formation and deep ocean ventilation50. Sea ice changes will also have contrasting influences on Adélie and emperor penguin colonies51,52, and substantially alter human activities along the Antarctic coastline.
Anthropogenic greenhouse gas emissions have been attributed as the primary cause of Southern Ocean warming, and here we suggest a potential link to a regime shift in Antarctic sea ice. While for many years, Antarctic sea ice increased despite increasing global temperatures6, it appears that we may now be seeing the inevitable decline, long projected by climate models53. The far-reaching implications of Antarctic sea ice loss highlight the urgent need to reduce greenhouse gas emissions.
Off the previous chart, again…. In 12 days another ~500,000 hectares have burned! Will the burning stop for winter? What does this portend for Australia’s upcoming El Nino summer?
The record for the 23rd blew the Canadian system’s off the chart! The following chart from Copernicus, the EU’s equivalent of NASA, that operates the satellites, suggests the data from the 23d is probably a real record of what the satellites actually recorded. In most years the wildfires would have been more-or-less through for the year. Yet 23 Sept shows BY FAR the largest number of hotspots recorded for the year so far, previous highs being 9269 for June 22 and 9692 for July 13.

Note 2: the following Guardian chart was PUBLISHED on 22 Sept.
Note: warmer winter temperatures allowed mountain pine beetle populations to grow explosively through this region due to additional reproduction of adult beetles that were normally killed off by hard freezing winters. I did several Facebook posts in 2016 and 2018 on the increasing fire hazard this would create until the dead biomass was removed. This year’s extreme temperatures facilitated this!
The Canadian 🔥 season is not yet done but I have a few URGENT questions we must address. 1. How many of these fires will burn underground overwinter and emerge as spring zombie fires? 2. How much extra permafrost will thaw because of this year’s severe burning? #ClimateCrisispic.twitter.com/Ih0ilRHQ6Q
[Note that 2020- Siberian wildfires plus this years’ wildfires in the Canadian Arctic Zone probably produced massive increases in permafrost GHG emissions beyond what was happening during the years included in this survey.]

Stationary anomaly, somewhat hotter on 23rd than 22nd
https://www.theguardian.com/environment/2023/sep/11/us-record-billion-dollar-climate-disastersNote, as the frequency, extent, and ferocity of climate disasters continue to increase with accelerating global warming, newer disasters will overlap and add to destruction from previous disasters where there has not been enough time to complete repair and remediation leading to the accelerating accumulated climate damage — until society no longer has the resources to continue repairing and replacing what has already been repaired and replaced. At this point social collapse is inevitable…… We must stop and reverse the process of global warming that is causing this or face near-term extinction.
11 September 2023 – Coming out of winter — not a good look for the rest of the year in Australia!
In February 2023, Antarctic sea ice set a record minimum; there have now been three record-breaking low sea ice summers in seven years. Following the summer minimum, circumpolar Antarctic sea ice coverage remained exceptionally low during the autumn and winter advance, leading to the largest negative areal extent anomalies observed over the satellite era. Here, we show the confluence of Southern Ocean subsurface warming and record minima and suggest that ocean warming has played a role in pushing Antarctic sea ice into a new low-extent state. In addition, this new state exhibits different seasonal persistence characteristics, suggesting that the underlying processes controlling Antarctic sea ice coverage may have altered. [my emphasis]

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

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

Key facts from CDR (Center for Disaster Recovery):
As of Sept. 15, the Libyan Red Crescent said the death toll had reached 11,300 people in Derna alone. Officials expect this figure to continue to rise, possibly as high as 20,000. About 170 people were also killed in other parts of eastern Libya, including in Susa, Marj, Bayda and Um Razaz. More than 7,000 people were injured and at least 10,100 people are still reported to be missing. Because of the lack of telecommunications, some may be displaced and unable to reach family, but due to the large-scale destruction, it is hard to confirm these figures.
According to Floodlist, Libya’s National Center of Meteorology reported, “in a 24 hour period to Sept. 10, a staggering 414.1 mm [16.2 inches] of rain was recorded in Bayda, while 240 mm [9.5 inches] of rain fell in Marawah in the District of Jabal al Akhdar, and 170 mm [6.7] fell in Al Abraq in the Derna District.”
I used publicly available satellite imagery to try assess the damage attributed largely due to the failure of two dams. My conclusion is that the dams were no more than momentary and relatively insignificant barriers to to the flow of an inconceivably large volume of water. The following satellite images from Google Earth, and Sentinel Hub’s EO Browser clearly demonstrate the power of our planet’s increasingly extreme weather events driven by global warming. As the oceans and atmosphere warm, the atmosphere is able to transport increasingly stupendous volumes of water (in the form of water vapor) over the land to be dropped when the air cools for any reason.
The following image is what appears to be the center of the city of Derna (pop ~100,000) immediately before Storm Daniel dropped part of its load of water in the watershed of Wadi Derna. The very dry stream bed of Wadi Derna crosses the center of the image. If you have access to Google Earth, you can zoom in to see shadows of the few individual people out in the mid-day sun.
Zooming in, note the large building on the NE side of the Wadi 3 blocks downstream from the bridge on the lower left corner of the picture. It is a high-rise, where the tallest part is 9 stories above the ground floor, and the rest five. I determined the number of floor by counting the sun shades visible on the downstream side of the building. This is one of the few structures left in this part of town that can be identified in the next image.
Immediately after it looked like this:
Note the conspicuous high-rise (10 stories) easily marked by its long shadow in this image. The image below images this building from the down-stream side. The image here is relatively low resolution, but the three lowest floors (facing AWAY from the flood) have clearly been gutted by the flood. The bridge referred to in the previous picture has vanished leaving only two supports (aligned with the stream flow) to show where it was. Rows of 4-6 story buildings (and even some 8 story buildings just off the left edge of this image) extending 3-4 and even more rows back from the Wadi have totally vanished or are only memorialized by a bit of concrete slab or trace of a foundation wall.
The next two pictures zoom in on the area between the vanished bridge in the above images and the next bridge upstream (just off the edge of the above).
The three buildings to the left of the Wadi at the bottom of the image were respectively 7, 4, and 7 stories high
The next two pictures show the site of the lower dam – 250 meters upstream from the inland edge of the city.
Note: the dam has no spillway. Overflow protection is provided by the flared drain pipe (circular structure) in the lower left of the picture. Using Google Earth’s measuring tool, the diameter of the drain as approximately 6m. On the upstream side the surface of the reed bed is ~24 m above sea level, and the level of the road over the top is 45 m, giving the dam height of 21 m. On the downstream side the base of the dam is at 26 m, with the outlet for the overflow drain at approx 22 m. The length of the dam across the top is ~115 m, across the bottom (at reed level) is 50 m; thickness at the bottom is ~74 m, 8.5 m at the roadway.
The next Google Earth image is of the upper dam (12.5 km upstream from the lower dam) from immediately before Storm David’s rain. There is no high resolution image available from after the flood.
The drain tube (right side upstream) seems to be 7m in diameter. The dam is ~10 m high and 270 m long. 143 m thick at the base and 6.5 m thick at the top.
The last composite graphic gives an impression of the amount of water held behind both dams in the days immediately prior to Storm David. All are sourced via Sentinel Hub’s EO Browser and all are at the same scale – close to the maximum resolution available. The left four images are of the upper dam and its lake, while those on the right are of the lower dam and its lake. The upper three images of each dam use the Normalized Difference Moisture Index NDMI – that basically highlights any moisture in the otherwise barren landscape. The bottom picture is the same view as the one immediately above, except that it displays “true colors”. On the left in the top picture, on 10/01/2023 there was some water backed up behind the dam, perhaps 2 m deep at the dam wall given that most of the upstream face is still dry. The second picture, on 02/09/2023 shortly before Storm Daniel shows essentially zero moisture behind the dam, except there is a tiny blue streak in the bottom of the bright yellow area that is too small to be resolved at the magnification shown here. The blue areas below the dam are well watered orchards and fields – not standing water. The dam is visible in both of the above pictures. The third picture, from 12/09/2023 immediately after Storm Daniel shows the Wadi Derna has been scraped clean of any sign of a dam or the well watered agricultural area below the dam save the blue area off to the side. Inspection of the area just downstream from the pictures here in the before and after show the complete obliteration of farms and vegetation together with the road to a height of 20+ meters above the bottom of the wadi. A little further upstream – a bit closer to the dam, the landscape has been scraped up to a height of 38 m! above the wadi bottom, where the width of the wadi is approximately 200 m across. The height of this point is ~215 m above sea level (at least 10 m higher than the top of the dam!).
A similar story can be constructed for the pictures of the lower dam in the right column. The dams were minor inconveniences to the flow of the total volume of the storm water.
The Wadi Derna drains a large and relatively barren plateau with some of the weirdest landforms I have seen, and could possibly be organized so it receives large volumes of water from a number of subsidiary drainages at the same time. Or, more likely, the insanely hot Mediterranean air was supersaturated with water, and the storm dynamics led to rapid cooling that squeezed all of the water out over a very short period of time….. And the barren plateau lacked soil and vegetation to slow the flow of the water once it hit the ground, and simply demonstrated what can happen when the Earth System has too much energy to dissipate all at once in the form of climate catastrophes.
Consequently….
Our planet is progressively becoming uninhabitable!

Leon Simons [Mission: To understand & protect the home planet. Innovator, climate researcher, social entrepreneur. Board member Club of Rome NL], who works outside the ‘reticence’ imposed by the usual academic and institutional employers considers the significance of recent reports on the Earth’s energy imbalance. Note: Simons is a coauthor on at least two peer reviewed scientific reports in this area.
Simons puts the previous graphs in a geological context based on Shackleton et al’s reconstruction of variations of Earth’s energy balance determined from measurements of Oxygen isotope ratios in sediment cores from the seabeds.
The thread from https://twitter.com/LeonSimons8/status/1698413266421096893 explains in some detail how the following graph was inferred and extrapolated from the above. At first I found it difficult to make sense of this graph until I grasped that the vertical line defining the right-hand side of the graph was data, comparing the imbalance observed directly over the last 50 years, with the variation recorded over the last 150,000[!] years, not the border….
Simons was one of the coauthors of the above paper.

Note that the following X-Tweet is limited to the United States – based on a Scientific American article. The rest of the world is suffering at least as much! Total costs are adjusted for inflation. It isn’t clear whether this also applies to the individual “billion dollar” events in the graph below.
Given the rapidly growing accumulation of excess heat in Earth’s oceans, if we cannot stop and reverse global warming within the next few years the inevitable result will be ecological and social collapses, within a few decades, and likely global extinction of most complex organisms — including humans within a century or so….
We must act before it is too late!

G20 nations broke records in 2022 subsidizing fossil fuel: $1.4 TN in 2022 — more than twice what they have invested in sustainable energy.
Clearly, fossil fuel subsidies help the greedy special interests whose carbon emissions are smothering our planet drag us towards mass extinction from the ‘runaway greenhouse‘. Equally clearly, members of governments approving and providing these subsidies must be getting something in return.
Public money still flowing into industry despite agreement to phase out ‘inefficient’ subsidies, thinktank says
The G20 poured record levels of public money into fossil fuels last year despite having promised to reduce some of it, a report has found.
The amount of public money flowing into coal, oil and gas in 20 of the world’s biggest economies reached a record $1.4tn(£1.1tn) in 2022, according to the International Institute for Sustainable Development (IISD) thinktank, even though world leaders agreed to phase out “inefficient” fossil fuel subsidies at the Cop26 climate summit in Glasgow two years ago.
The report comes ahead of a meeting of G20 countries in Delhi next month that could set the tone for the next big climate conference, which takes place in the United Arab Emirates in November.
It is crucial that leaders put fossil fuel subsidies on the agenda, said Tara Laan, a senior associate with the IISD and lead author of the study. “These figures are a stark reminder of the massive amounts of public money G20 governments continue to pour into fossil fuels – despite the increasingly devastating impacts of climate change.”
Scaling back subsidies would reduce air pollution, generate revenue, and make a major contribution to slowing climate change.
Fossil-fuel subsidies surged to a record $7 trillion last year as governments supported consumers and businesses during the global spike in energy prices caused by Russia’s invasion of Ukraine and the economic recovery from the pandemic.
As the world struggles to restrict global warming to 1.5 degrees Celsius and parts of Asia, Europe and the United States swelter in extreme heat, subsidies for oil, coal and natural gas are costing the equivalent of 7.1 percent of global gross domestic product. That’s more than governments spend annually on education (4.3 percent of global income) and about two thirds of what they spend on healthcare (10.9 percent).
…
As the Chart of the Week shows, fossil-fuel subsidies rose by $2 trillion over the past two years as explicit subsidies (undercharging for supply costs) more than doubled to $1.3 trillion. That’s according to our new paper, which provides updated estimates across 170 countries of explicit and implicit subsidies (undercharging for environmental costs and forgone consumption taxes).

The longer this evil cycle continues the less likely our escape from the dead-end road ending in Earth’s hothouse hell becomes. Seemingly, the only way we can find a side-road to a sustainable future is by replacing our present puppet governments with people committed to representing the interests of those who voted for them.
The only for them to know they will be replaced if they don’t do this is if for everyone who thinks this to tell their government representatives by post, email, phone, or old-fashioned knocking on the electoral office door. Only if enough people do this to convince special interest supporters that they really will be out of a job, will they begin to take the climate emergency seriously.
It is in your hands to start this action. VoteClimateOne.Org has the addresses and information you need to do this, and many other climate or energy action groups can also help you to power your tangible demands for action.
If you want to understand the climate crisis, see what VoteClimateOne.Org is telling our federal and state governments, and Climate Sentinel News for the real evidence of what is going on with the climate:
If you reference any of our evidence in your petitions to government member, they will know that a lot more people than you will be working to remove them from office if they don’t respond with serious climate action. See ACT NOW! and Traffic Light Voting.

What’s this article about, and why is the date important?
As I write this, the average climate for our WHOLE PLANET is changing so freaking fast we can see visibly measurable changes in the averages from one day to the next!
The sudden speed up of changes in several climate indicators at the same time suggests that we may be crossing a critical tipping point in the complex interactions of important temperature related feedbacks controlling the behavior of Earth’s Climate System, as shown in the Featured Image. The speed-up is highlighted by the fact that the average air temperature 2 meters above the surface of our planet is at an all time record (and especially in the satellite era beginning in 1979). These changes will affect the whole 8,000,000,000+ humans and alive today along with all other life on the planet. The charts and maps presented here graphically illustrate measurements of important climate variables up to the last 1 to 4 days.
Fig. 1. ClimateReanalyzer’s Time Series plotting of Earth’s global average temperature at 2 meters above the surface from the NCEP Climate Forecast System (CFS) version 2 (April 2011 – present) and CFS Reanalysis (January 1979 – March 2011). CFS/CFSR is a numerical climate/weather modeling framework that ingests surface, radiosonde, and satellite observations to estimate the state of the atmosphere at hourly time resolution onward from 1 January 1979. The horizontal gridcell resolution is 0.5°x0.5° (~ 55km at 45°N). The time series chart displays area-weighted means for the selected domain. For example, if World is selected, then each daily temperature value on the chart represents the average of all gridcells 90°S–90°N, 0–360°E and accounts for the convergence of longitudes at the poles.
Again, every day since July 3 has been hotter than any maximum temperature recorded for any prior year back to 1979 when these records were compiled.
@EliotJacobson on Twitter shows this data a bit more legibly. The first record high was on 3 July, and daily average temperatures have remained in annual record high regions for a total of 12 ! continuous days through 14 July. The record is now 21 days!

The time gap between the instants of measurement depicted in the plots and charts and when they were printed are due to time delays between:
automatically recording millions of readings from hundreds of thousands of networked physical sensors and more millions of readings from remote sensors on a plethora of artificial satellites whizzing around our revolving planet several times a day (“Intensity of observation”, below, illustrates just how comprehensive the sensor network is);
accumulating and assembling the recorded data over the world-wide communications network;
proofing, processing and tabulating the received data on the world’s largest supercomputers; reanalyzing and plotting the observations in the form of charts and graphs comprehensible to humans;
publishing and publishing these outputs onto the public web, where they are accessible to anyone with a computer and the knowledge to find and understand the representations.
Based on the most recent measurements, the ongoing climate changes are accelerating in directions and speeds that will inevitably be lethal to the human and many other species within another century, more or less, if the changes are not stopped and reversed. These changes are a direct consequence of an unplanned experiment that humans began around 1½ centuries ago to burn geologically significant quantities of fossil carbon (e.g., coal, oil, ‘natural’ gas) into usable energy and greenhouse gases trapping an ever growing proportion of the total solar energy striking Planet Earth.
However, some of the combustion energy released by burning fossil carbon has also fueled an exponential growth of knowledge and technology able to produce the I am showing here. These plots provide the evidence our experiment is changing our global climate system to a state that will have existentially catastrophic consequences for Earth’s complex forms of life. This Hellish state is known as “Hothouse Earth“.
This fact that we now have the tools to actually see the evidence of our likely doom gives me some hope that our still exponentially improving technology may also provide us with the ability to stop further damage caused by our rogue experiment and repair enough of the damage already caused, to allow our species to continue evolving into the foreseeable future.
This raises the unavoidable and fraught question: Do we humans have the political will and capability to marshal and mobilize our technologies to engineer solutions that will allow us to avoid the abyss? This is the single most important issue facing the world today. If we don’t solve it, no other issue matters because — before long — no one will be left to worry about it.
Problematically, the world’s governments are dominated by puppets of the fossil fuel industry and related interests. They are doing as much as they can to PREVENT, DELAY, or MINIMIZE any actions that might hamper fossil fuel’s greed and short term interests for the world to burn yet more fuel. Hoping that we humans can solve this single, most important issue, VoteClimateOne is working to revolutionize our governments by replacing or changing parliamentary puppets to prioritize actions to solve the climate crisis first. Also, I am writing articles such as this to demonstrate and explain why this revolution is so urgent and necessary.
To demonstrate just how rapidly we are currently moving down the road to doom in what will be Earth’s Hothouse Hell, this article will be updated at least once a week until there is evidence of a downward trend to safer readings. We are certainly not seeing them yet!
Measuring progress towards existential catastrophe on Hothouse Earth
The world’s polar regions are critical. Ice and snow covering land and ocean reflects around 90% of the solar energy striking it. As temperature rises, more of the frozen water melts, allowing the exposed earth and water to absorb a much greater proportion of the solar energy during 24 hour-long polar polar daylight (open ocean absorbs ~94% of the energy striking it) , causing polar and global temperatures to rise in a potentially accelerating feedback cycle. In the animated graphic below, this process is clearly visible since the mid 1930s. This particular cycle won’t be broken until the ice is essentially all melted. By then there are several other feedbacks that will likely be in full swing.
Fig. 3. Zonal-mean (averaged over longitude) temperature anomalies for each year from 1900 to 2022. The x-axis is latitude (not scaled by distance), and the y-axis is the temperature anomaly. Data is from Berkeley Earth Surface Temperatures (BEST; http://berkeleyearth.org/data/) using a reference period of 1951-1980. (Zachary Labe 2023. Climate Indicators.
Ocean measurements are critical
Because most humans live on continental land masses, immersed in the atmosphere, most climatologists are primarily concerned with what goes on in the atmosphere. However, because water covers some 70% of our planet’s surface and because of water’s physical properties, around 90% of the excess solar energy striking Earth is absorbed in the World Ocean. Heat is then transported around the planet in currents and is available to be released to drive climate. See belowfor explanations of how the major heat engines driving Earth’s Climate System interact and work.
Fig. 4. Growing heat content held by our warming Ocean Current to Feb. 2023 (NOAA data)
Because these climate ‘engines’ are complex dynamical systems with many interacting components, where the interactions are often non-linear and sometimes even chaotic (in a mathematical sense their behavior is inherently unpredictable to any statistically define degree. Positive feedbacks in such systems can be potentially destructive because they lead to exponentially growing changes that lead to system breakdown (because infinity is impossible in the real world). Mathematical modeling of the interactions of small sets of variables can provide an appreciation of how such breakdowns may occur. Systems engineering as practiced in large defence engineering projects is based around a MilStd known as Failure Modes Effects and Criticality Analysis (FMECA) to identify such kinds of failure modes in order to engineer system solutions mitigate or totally avoid circumstances where they might arise.
The charts and maps below show how some measures of the behavior of Global Climate System have been behaving over the last few months and days. I consider these to be critical because they are likely to be evolved in the kinds of positive feedbacks that can grow exponentially to cause systems failure or collapse.
A definition
Many of the charts represent values of particular variables averaged over the surface of the whole Earth (or some specified region) at a specified point or interval of time. Most maps use colors to indicate the value of a specified variable at a specified point or averaged over an interval of time. In most such cases these measures are presented in the form of “anomalies”. An anomaly is the difference between the particular measurement and the long-term ‘baseline’ average for that measure on that day or interval of the year. For example, the graph immediately below uses a 30 year average (from 1971-2000) for its baseline average. Anomaly plots are particularly useful to highlight changes taking place over time.
Critical Variables
Global Sea-Surface Temperature
The global sea surface temperature anomaly broke into all-time record for the day of the year around 15 March, and by the end of March it was an all time record high since 1981, 0.1 °C above the previous record set on 6 March 2015. This value is so extreme, that along with other variables noted below it suggests that the average rate of global warming observed over the last few decades may be shifting into a new regime where the rate of ocean-surface warming is skyrocketing. As at 29 June it is still 0.2 °C above the previous record for that date – with an uptick after 4 days of downward trend).
Fig. 5a. Time series visualizations of daily mean Sea Surface Temperature (SST) up to 23 July. Data from NOAA Optimum Interpolation SST (OISST) version 2.1. OISST is a 0.25°x0.25° gridded dataset that provides estimates of temperature based on a blend of satellite, ship, and buoy observations. The datset spans 1 January 1982 to present with a 1 to 2-day lag from the current day. Data are preliminary for about two weeks until a finalized product is posted by NOAA. This status is identified on the maps by “[preliminary]” appearing in the title, and applies to the time series as well. SST anomalies, which are included in the OISST dataset, are based on 1971–2000 climatology. The time series chart displays area-weighted means for the selected domain. For example, if World 60S-60N is selected, then each daily SST value on the chart represents the average of all ocean gridcells between 60°S and 60°N across all longitudes, and accounts for the convergence of longitudes at the poles. Hide or display individual time series by clicking the year below the chart; Hide All and Show All buttons are at the chart lower right. The map can be switched between SST and SST anomaly by clicking the toggle button at the map top-left. A sea ice mask is applied to the SST and anomaly maps for gridcells where ice concentration is >= 50%

The North Atlantic’s fever is still has a fever is still growing on 13 July. Warmer than usual water flooding up around southern Greenland right up to the edge of the melting sea-ice, with what looks like cold fresh meltwater flowing out of Baffin Bay along the west side.
Note that the ocean surface temperature is 5 °C right up to the edge of the sea ice, with warmer water than that intruding nearly as far as the ice front in Baffin Bay. The cooler (purple shaded) water flowing down close to the Canadian shoreline has been pushed back into Baffin Bay (between Greenland and Canada. There is no sign in either of the SST maps of ‘cool spots’ which are thought to be the sources of the ‘salty cold water’ forming the deep water branches of the thermohaline circulation in the North Atlantic. In fact, the ocean in these areas seems to be 10-15 °C. Northern Hemisphere ice extents are low for the date but not yet near record lows, unlike the South!

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

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

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

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

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

It is one of several oceanographic data plotting visualizations for the Arctic (see System information). Presumably in the light lavender areas the remaining ice could disappear in a few days of warm temperatures. See also Danish Arctic Research Institution’s Polar Portal for current info on the northern polar region.
Arctic sea ice beginning to thin and break up as far as the North Pole. Shades of blue within the ice cap show regions where less than 100 percent of the quadrangle are covered by ice. (Either due to exposed ocean water or puddles of rain/melt-water on top of the ice). In either case this is bad news for reflectivity of the ice cap.

Atmosphere and land
Jet streams
Fig. 13a. Jet streams in the Southern Hemisphere.
Fig. 13b. Jet streams in the Northern Hemisphere
Fig. 13c. Global distribution of jet streams.
Jet streams are the atmospheric equivalents to major ocean currents that influence all of the other weather systems on the planet to keep them moving latitudinally around the planet. They are driven by temperature differences between the tropical and polar regions of the Earth and Coreolus effects as winds blow towards or away from the poles. Where the temperature differs strongly between poles and equator the jet streams are well organized with high winds. As temperature differences decrease so do the wind speeds, and the streams begin to slowly meander until they may become quite chaotic. Winds less than 60 kt are not considered to be jet streams. At present there has been very little change in the pattern that existed a week and a half ago (as shown in Fig 8b) there are virtually NO jet streams at all in the Northern Hemisphere, and the winds that do exist are completely chaotic — a highly unusual situation. This leaves major heat domes basically motionless, facilitating the buildup and maintenance of record high temperatures.
Fig. 14. The taiga biome is found throughout the high northern latitudes, between the tundra and the temperate forest, from about 50°N to 70°N, but with considerable regional variation. (Wikipedia).
Some of the greatest impacts of the disrupted jet stream system are seen over the boreal/taiga forest zones of North America and Eurasia. Arctic tundra and much of the taiga is underlain by carbon rich peat and peaty permafrost soils that are thought to contain at least 2x more carbon than the current amount of carbon in our atmosphere. Depending on circumstances, significant amounts of that carbon can be released in the form of methane, that has more than 80x the greenhouse potential of CO2 over the first 20 years of emission (20x over 100 years). Aside from greenhouse gases emitted by the burning forests and soils, significant amounts of the black carbon ‘ash’ will settle on Arctic snow and ice – speeding their melting when exposed to sunlight. Collectively, at least over the first few years following wildfire, the burning will provide yet another powerful positive feedback to speed snow and ice melting. Over a longer term, re-vegetation will sequester some atmospheric CO2, but only if the forest is not burned again.
Fig. 15.By the end of June Canadian wildfires mainly in boreal forests have burned more area before the fire season is half over than in the previous record for a full year in 1989. Phys Org (30 June 2023). As at 24 July 11,582,531 ha have burned. The graph here, sourced from Natural Resources Canada gives the status as at 15 July. This is literally ‘off the chart’, and represents about 1.1% of Canada’s total land area.
If the burning releases more greenhouse emissions than can readily be recaptured by re-vegetating forests. These emissions may more than replace any emissions humans cut — providing positive feedback to drive global temperatures still higher. This is one of several crucial tipping points associated with stopping the thermohaline circulation.
Intensity of observation
A hint to how little you can trust claims of reality denying trolls, puppets, and the like, is provided by the number monitoring points that physically monitor the atmosphere at those locations around the surface of the planet we live on used PER DAY.
Atmospheric monitoring
The European Centre for Medium-Range Weather Forecasts (ECMWF) for the charts plotted on 6 July 2023 as shown below are based on measurements from 92,702 locations. Note 1: this map does not NOT include ocean monitoring points. Note 2: The DATA COLLECTED EVERY DAY by this web of sensors is available to, used, and interpreted by several different national and institutional climate monitoring centers. In other words, the conclusions are cross checked between different centers many times over. The charts above depict scientific facts, not hunches and personal opinions. For more detail on how the accuracy of the observations is controlled see ECMWF’s Monitoring of the observing system.
Fig. 19. The type and location of 92,702 separate observations used on 6 July 2023 between 3:00 and 9:00 PM for 6 hourly data coverage used by the ECMWF data assimilation system (4DVAR). Each plot shows the available data for a family of observations. The current day’s chart can be downloaded here. SYNOP refers to encoded information collected and transmitted every 6 hours by more than 7600 manned and unmanned meteorological stations and more than 2500 mobile stations around the world and is used for weather forecasting and climatic statistics. SHIP METAR is a format for reporting weather information. A METAR weather report is predominantly used by aircraft pilots, and by meteorologists, who use aggregated METAR information to assist in weather forecasting.
Oceanographic monitoring
Argo
Argo floats profiles physical properties of the surrounding water, minimally ocean temperature, salinity, pressure (i.e., depth). Each float operates on a 10 day cycle, spending most of the cycle ‘resting’ at an intermediate depth. On the 10th day it sinks to a specified depth and begins recording inputs from its sensors as it floats up to the surface. The standard float sinks to a depth of 2 km (2,000 m) and records all the way up to the surface, where it then determines its GPS position to within a few meters and messages a passing relay satellite with its location and profile data before sinking to its resting depth waiting for the next profile position. As shown on the world map here, for June 2023, shows the locations of 3849 profiles received over the month. Of these ~1,400 recorded the profile from 2 km deep in the ocean to the surface. Some floats are designed to sink to the bottom and thus record a profile for the full depth of the ocean. A few include several additional sensors to levels for things like acidity, oxygen, nitrate, light level, and some more I don’t recognize. The Argo system is really quite amazing.
Some even have ice sensors allowing them to operate even in ice-covered waters by warning if they might be fatally damaged by striking ice overhead. For these, if they sense ice, they’ll record the profile in memory, and drop back and rest until the next cycle (which may again prevent surfacing). These interrupted cycles will keep repeating until the float can safely surface — in which case all of the aborted profiles will be messaged to the satellite relay along with the current one (better late than never!)
Fig. 20. Argo floats operational in June 2023. For the latest data see Ocean Ops dashboard
And then there is a plethora of other ocean sensor systems. The full gamut of them shown next. The various different types are named in the legend. Collectively, on 26 June 2023, the ocean sensing system measuring in-situ variables includes 7973 ‘platforms’ (including the different kinds of Argo Floats) and results from 104 ‘cruises’ of ships ranging from specialized oceanographic vessels to fishing boats. Some of these non-Argo systems also record partial or complete (i.e., to the bottom) profiles.
Almost all of the data collected from the range of sensors is freely accessible via the public World Wide Web.
Fig. 21. Location of ocean sensor platforms.
Satellite remote sensing systems
As if the plethora of physical systems for directly measuring weather and climate is not enough. There is now a cloud of satellite-based remote sensing systems buzzing around our planet, making literally millions of observations every day of critical weather and climate variables. NASA EarthData’s What is remote sensing? gives a high level overview of some of the capabilities of these systems. You can be assured that the measurements made by the earth-based and space-based sensing systems are carefully cross calibrated to ensure the various systems are all working together towards a common view of the actual physical reality.
Major heat engine domains of the Earth System
Dynamic changes in the Universe through time are driven by spontaneous flows and transformations of energy from ‘sources’ at high potential to entropy and ‘sinks’ at lower potentials (e.g., water flowing down a hill). This flux can be used to drive other processes through a system of coupled interactions forming a thermodynamic system or heat engine. As governed by the universal physical Laws of Thermodynamics (especially the Second Law), as long as there is a potential difference between source and sink, the flux of energy between them will continue to spontaneously flow through the system/heat engine as long as long as the system’s net entropy production remains positive.
The ‘Earth System’ includes all the shell-like layered components of the planet from the edge of outer space to its center. The three main ones concerning us here from inside out are the geosphere, hydrosphere, and atmosphere. The biosphere formed in the interface between atmosphere and geosphere (on the planetary scale) is a microscopically thin turbulent layer of carbonaceous macromolecules and water combined with other elements and molecules exhibiting the properties of life. We humans form part of that biosphere.
The heat engines described here circulate masses of matter that transport heat energy from place to place within the Earth System.
Geosphere
The geosphere comprises Planet Earth’s, solid (‘rocky’) components. The geosphere’s heat engine is based on the geologically slow process of plate tectonics that drives continental drift.
Fig. 22. Geological heat engine at work. Mantle convection may be the main driver behind plate tectonics. Image via University of Sydney.
The plate tectonics engine is driven by the slow radioactive decay of unstable isotopes of elements such as potassium, uranium and thorium remaining from the formation of Earth some 4.5 billion years ago.
Enough heat has and is being generated by this decay to melt the planet’s core and heat and expand the overlying mantle rocks enough to make them less dense and plastic enough for them to form convection cells like you see in a pan of nearly boiling water. Hotter and less dense rocks float up towards Earth’s harder crust and spread out (carrying surface crust and even lighter continental rocks, i.e., ‘plates’) to become cool enough for gravitational force to pull the solidified plates back towards the molten core in subduction zones that also form oceanic trenches.
Heat transported from radioactive decay is released into the hydrosphere and atmosphere from conduction through the crust + hot springs and geysers; by molten basalt lava coming to the surface in oceanic and terrestrial spreading (‘rift zones’); and volcanoes associated with localized ‘hot spots of rising magma or with the rift zones. Lavas associated with the latter type of volcanoes are formed of lighter, lower melting point rocks forming a scum on top of the denser crustal rocks of the drifting plates.
Hydrosphere
Earth’s hydrosphere is the thin film of water between the geosphere and atmosphere forming the salty Ocean covering around 70% of the planetary surface along with lakes and streams of generally nearly salt-free water serving as feeding tendrils draining water condensed from the land. The hydrosphere also includes a solid component of ice and a gaseous component of vapor. These components have very different properties compared to water and each other.
The liquid component of the hydrospheric heat engine absorbs solar energy in the form of heat warming volumes of water, in the form of latent heat of fusion (i.e., melting of ice) absorbing about 80 cal/gm of ice melted, and latent of vaporization (i.e., turning liquid water into an atmospheric gas) absorbing about 540 cal/gm of water vaporized (6.75 times as much energy as required to melt the gm of ice). The heat absorbed becomes ‘latent’ in that the energy transforms the state from liquid to solid or from liquid to gas without changing the measurable or feel-able (i.e., ‘sensible’) temperature of the mass. When the water vapor condenses or the water freezes, of course the latent energies are released in the form of sensible heat.
Basically, the hydrospheric heat engine is driven by the absorption of excess amounts solar radiation (the source) in equatorial, tropical, and subtropical regions of the planet that is mainly carried by ocean currents towards the polar and sub-polar regions where the an excess of heat energy released from water and freezing ice is carried away from the planet in the form of long-wave infrared radiation to the cold sink of outer space. Many different local, regional, and global ocean currents are involved in moving energy around the planetary sphere. Proportionately, a small amount of geothermal heat energy is absorbed from the geospheric heat engine by water, and larger amounts of heat are exchanged with the atmospheric heat engine(s) in a variety of ways.
Water has some very peculiar properties that play very important roles in the climate system and biospheric systems, especially around the freezing point. Most materials contract and become denser as they cool. This is also true for pure water, down to a temperature of 4 °C when it begins to expand and become less dense until it begins to freeze. Ice at 0°C is even lighter such that it easily floats. This is because water molecules are shaped like boomerangs with the oxygen atom at the apex and the two hydrogen atoms sticking out at angles. When they are warmer they jitter around in a relatively random way, such that warming makes the molecules jitter faster and further, while as they cool the jitter slows and they come closer such that a given number of molecules take up less space. As the jitter slows further at and below 4 °C, molecules tend to spread out some to form a quasi crystalline structure approaching that of ice where they are more or less locked into that structure, where the solid water is significantly lighter than the liquid. The presence of dissolved salts and minerals depresses the freezing temperature. As as ice freezes, crystallization of the water also tends to concentrate and expel dissolved minerals and gases in extra-cold plumes of particularly dense and very cold salty water (i.e., brine) — cold enough that tubes of ice may form from the less salty water around the brine.
Water is also a god solvent, able to carry substantial amounts of gases, (e.g., oxygen, CO2, methane – CH4), salts, carbonates, nitrates, sulfates, metal ions, etc). The ocean carries a lot of salt – enough to play an important role in the ocean circulation system. Oxygen and CO2 play essential roles in living systems, CO2 and carbonates play important roles in interactions between water, the Geosphere and the atmosphere. CO2 and methane in the atmosphere, along with water vapor, are the most important greenhouse gases, etc…..
Fig. 23. A summary of the path of the thermohaline circulation. Blue paths represent deep-water currents, while red paths represent surface currents. This map shows the pattern of thermohaline circulation also known as “meridional overturning circulation”. This collection of currents is responsible for the large-scale exchange of water masses in the ocean, including providing oxygen to the deep ocean. The entire circulation pattern takes ~2000 year. Wikipedia
The principal current system driving ocean heat transport is known as the ‘thermohaline circulation‘. Basically, seawater is warmed in the equatorial, tropical and subtropical regions of the world. It also increases in density due to the evaporation of water vapor into the atmosphere. However, parcels of water are kept hot enough that thermal expansion more than compensates for the densification from becoming saltier. However, as currents carry the hot, salty surface water further towards the poles, the water begins to cool until the warm salty water carrying a full load of oxygen becomes dense enough around 4 °C to sink through layers of still warmish but less salty water, carrying a full load of oxygen down to the bottom of the ocean. The salt in this descending water is diluted by mixing with relatively fresh ice water from terrestrial runoffs, melting glacial and sea ice, etc sourced from zones even closer to the poles than where the dense salty water normally sinks.
The main source of power that drives the thermohaline circulation heat engine is the conversion gravitational potential energy in the sinking masses of water as they sink to the ocean floor this sinking helps to pull surface waters into the ‘sinkhole’. Further assists to the circulation are provided by prevailing atmospheric winds pushing surface waters away from continental shores, pulling up cold, deoxygenated, CO2 and mineral rich deep waters to the surface where they fertilize the blooms of micro-algae that add more oxygen and feed the whole food chains of larger organisms in the oceans.
Atmosphere
Fig. 24. (top)Plan and (bottom) cross-section schematic view representations of the general circulation of the atmosphere. Three main circulations exist between the equator and poles due to solar heating and Earth’s rotation: 1) Hadley cell – Low-latitude air moves toward the equator. Due to solar heating, air near the equator rises vertically and moves poleward in the upper atmosphere. 2) Ferrel cell – A midlatitude mean atmospheric circulation cell. In this cell, the air flows poleward and eastward near the surface and equatorward and westward at higher levels. 3) Polar cell – Air rises, diverges, and travels toward the poles. Once over the poles, the air sinks, forming the polar highs. At the surface, air diverges outward from the polar highs. Surface winds in the polar cell are easterly (polar easterlies). A high pressure band is located at about 30° N/S latitude, leading to dry/hot weather due to descending air motion (subtropical dry zones are indicated in orange in the schematic views). Expanding tropics (indicted by orange arrows) are associated with a poleward shift of the subtropical dry zones. A low pressure band is found at 50°–60° N/S, with rainy and stormy weather in relation to the polar jet stream bands of strong westerly wind in the upper levels of the atmosphere. From Wikipedia Hadley Cell.
The atmosphere includes the gaseous components of Earth’s global heat engine. The transport and transfer of heat energy and the Coriolis effect are the major drivers. The major sources of heat are direct conduction of sensible heat across the atmosphere : ocean/land interface, the conversion of latent heat into sensible heat through the evaporation and condensation of water vapor (mainly from the oceans), and direct solar heating (note: because the atmosphere is largely transparent to most radiation, most solar energy is not captured by the atmosphere itself.)
The diagram here shows how the transport of heat from the Earth’s surface to the top of the atmosphere where it radiates away as infrared to the heat sink of outer space organizes the wind systems into three major cycles. Note that the moisture laden warm air cools as it rises and releases a lot more energy as the water vapor condenses into rain or hail to keep the rising air warmer for longer.
Biosphere
The Biosphere (“Life”) – the totality of the living components of the planetary sphere, generally residing in the interface between the Atmophere and the Geosphere/Hydrosphere, where living things are characterized by their capacity to self-organize, self-regulate, and self-reproduce their properties of life through time.
Fig. 25. The biosphere of living things (NASA’s Goddard Space Flight Center, via Wikipedia). False colors are used to show seasonal changes in the concentration of chlorophyll over the annual cycle. On land, vegetation appears on a scale from brown (low to zero vegetation) to dark green (lots of vegetation); at the ocean surface, phytoplankton are indicated on a scale from purple (low) to yellow (high) and red (highest). This visualization was created with data from satellites including SeaWiFS, and instruments including the NASA/NOAA Visible Infrared Imaging Radiometer Suite and the Moderate Resolution Imaging Spectroradiometer.
The biosphere’s “Engine of Life” is predominantly driven by the complexly catalyzed formation of high energy chemical bonds from the capture of solar radiant or activation energy from redox reactions to combine oxygen and carbon to produce high energy carbohydrates (i.e., captured by chlorophyll in photosynthesis) used or ‘burned’ to fuel all kinds of metabolic activities and processes in living things. Living components of the Earth System have and depend for their continued survival and reproduction on their capacity to catalyze all kinds of energy transformations within and between the other Earth Systems. Over time the Engine of Life has profoundly affected the other planetary spheres. A tiny fraction of energy is captured in abyssal depths and deep in the earth through the process of chemosynthesis
Over evolutionary time the emergence and evolution Life has affected major global transformations involving many aspects of Earth’s other subsystems. Evolutionary processes are complexly dynamic and many of them include many potentially powerful positive feedbacks able to drive changes at exponential rates. All life can evolve genetically to live under a wide variety of environmental conditions over multi generational time scales due to natural selection at the genetic level.
A few species and humans in particular, can evolve culturally at intra-generational timescales to drive changes at exponentially explosive rates to the extent that WE are literally threatening all complex life on the planet with global mass extinction – quite possibly within two or three of our own generations!
Interpersonal competition to gain ever more personal power from the burning of globally significant quantities of fossil carbon in less than a century that was accumulated in the geosphere over millions of years by life processes has destabilized Earth’s Climate System. TODAY, we seem to be in the midst of flipping the global climate system from the Glacial-Interglacial Cycle most life has adapted genetically to live under, to the Hothouse Earth regime that very few organisms will be able to survive in without hundreds or thousands of generations or more of genetic adaptation.

What’s this article about, and why is the date in the title important?
As I write this, the average climate for our WHOLE PLANET is changing so freaking fast we can see visibly measurable changes in the averages from one day to the next!
The sudden speed up of changes in several climate indicators at the same time suggests that we may be crossing a critical tipping point in the complex interactions of important temperature related feedbacks controlling the behavior of Earth’s Climate System, as shown in the Featured Image. The speed-up is highlighted by the fact that the average air temperature 2 meters above the surface of our planet is at an all time record (and especially in the satellite era beginning in 1979). These changes will affect the whole 8,000,000,000+ humans and alive today along with all other life on the planet. The charts and maps presented here graphically illustrate measurements of important climate variables up to the last 1 to 4 days.
Fig. 1. ClimateReanalyzer’s Time Series plotting of Earth’s global average temperature at 2 meters above the surface from the NCEP Climate Forecast System (CFS) version 2 (April 2011 – present) and CFS Reanalysis (January 1979 – March 2011). CFS/CFSR is a numerical climate/weather modeling framework that ingests surface, radiosonde, and satellite observations to estimate the state of the atmosphere at hourly time resolution onward from 1 January 1979. The horizontal gridcell resolution is 0.5°x0.5° (~ 55km at 45°N). The time series chart displays area-weighted means for the selected domain. For example, if World is selected, then each daily temperature value on the chart represents the average of all gridcells 90°S–90°N, 0–360°E and accounts for the convergence of longitudes at the poles.

The time gap between the instants of measurement depicted in the plots and charts and when they were printed are due to time delays between:
automatically recording millions of readings from hundreds of thousands of networked physical sensors and more millions of readings from remote sensors on a plethora of artificial satellites whizzing around our revolving planet several times a day (“Intensity of observation”, below, illustrates just how comprehensive the sensor network is);
accumulating and assembling the recorded data over the world-wide communications network;
proofing, processing and tabulating the received data on the world’s largest supercomputers; reanalyzing and plotting the observations in the form of charts and graphs comprehensible to humans;
publishing and publishing these outputs onto the public web, where they are accessible to anyone with a computer and the knowledge to find and understand the representations.
Based on the most recent measurements, the ongoing climate changes are accelerating in directions and speeds that will inevitably be lethal to the human and many other species within another century, more or less, if the changes are not stopped and reversed. These changes are a direct consequence of an unplanned experiment that humans began around 1½ centuries ago to burn geologically significant quantities of fossil carbon (e.g., coal, oil, ‘natural’ gas) into usable energy and greenhouse gases trapping an ever growing proportion of the total solar energy striking Planet Earth.
However, some of the combustion energy released by burning fossil carbon has also fueled an exponential growth of knowledge and technology able to produce the I am showing here. These plots provide the evidence our experiment is changing our global climate system to a state that will have existentially catastrophic consequences for Earth’s complex forms of life. This Hellish state is known as “Hothouse Earth“.
This fact that we now have the tools to actually see the evidence of our likely doom gives me some hope that our still exponentially improving technology may also provide us with the ability to stop further damage caused by our rogue experiment and repair enough of the damage already caused, to allow our species to continue evolving into the foreseeable future.
This raises the unavoidable and fraught question: Do we humans have the political will and capability to marshal and mobilize our technologies to engineer solutions that will allow us to avoid the abyss? This is the single most important issue facing the world today. If we don’t solve it, no other issue matters because — before long — no one will be left to worry about it.
Problematically, the world’s governments are dominated by puppets of the fossil fuel industry and related interests. They are doing as much as they can to PREVENT, DELAY, or MINIMIZE any actions that might hamper fossil fuel’s greed and short term interests for the world to burn yet more fuel. Hoping that we humans can solve this single, most important issue, VoteClimateOne is working to revolutionize our governments by replacing or changing parliamentary puppets to prioritize actions to solve the climate crisis first. Also, I am writing articles such as this to demonstrate and explain why this revolution is so urgent and necessary.
To demonstrate just how rapidly we are currently moving down the road to doom in what will be Earth’s Hothouse Hell, this article will be updated at least once a week until there is evidence of a downward trend to safer readings.
Measuring progress towards existential catastrophe on Hothouse Earth
Ocean measurements are critical
Because most humans live on continental land masses, immersed in the atmosphere, most climatologists are primarily concerned with what goes on in the atmosphere. However, because water covers some 70% of our planet’s surface and because of water’s physical properties, around 90% of the excess solar energy striking Earth is absorbed in the World Ocean. Heat is then transported around the planet in currents and is available to be released to drive climate. See belowfor explanations of how the major heat engines driving Earth’s Climate System interact and work.
Fig. 2. Growing heat content held by our warming Ocean Current to Feb. 2023 (NOAA data)
Because these climate ‘engines’ are complex dynamical systems with many interacting components, where the interactions are often non-linear and sometimes even chaotic (in a mathematical sense their behavior is inherently unpredictable to any statistically define degree. Positive feedbacks in such systems can be potentially destructive because they lead to exponentially growing changes that lead to system breakdown (because infinity is impossible in the real world). Mathematical modeling of the interactions of small sets of variables can provide an appreciation of how such breakdowns may occur. Systems engineering as practiced in large defence engineering projects is based around a MilStd known as Failure Modes Effects and Criticality Analysis (FMECA) to identify such kinds of failure modes in order to engineer system solutions mitigate or totally avoid circumstances where they might arise.
The charts and maps below show how some measures of the behavior of Global Climate System have been behaving over the last few months and days. I consider these to be critical because they are likely to be evolved in the kinds of positive feedbacks that can grow exponentially to cause systems failure or collapse.
A definition
Many of the charts represent values of particular variables averaged over the surface of the whole Earth (or some specified region) at a specified point or interval of time. Most maps use colors to indicate the value of a specified variable at a specified point or averaged over an interval of time. In most such cases these measures are presented in the form of “anomalies”. An anomaly is the difference between the particular measurement and the long-term ‘baseline’ average for that measure on that day or interval of the year. For example, the graph immediately below uses a 30 year average (from 1971-2000) for its baseline average. Anomaly plots are particularly useful to highlight changes taking place over time.
Critical variables
Global sea-surface temperature
The global sea surface temperature anomaly broke into all-time record for the day of the year around 15 March, and by the end of March it was an all time record high since 1981, 0.1 °C above the previous record set on 6 March 2015. This value is so extreme, that along with other variables noted below it suggests that the average rate of global warming observed over the last few decades may be shifting into a new regime where the rate of ocean-surface warming is skyrocketing. As at 29 June it is still 0.2 °C above the previous record for that date – with an uptick after 4 days of downward trend).
Fig. 3a. This chart provides time series visualizations of daily mean Sea Surface Temperature (SST) up to 4 July from NOAA Optimum Interpolation SST (OISST) version 2.1. OISST is a 0.25°x0.25° gridded dataset that provides estimates of temperature based on a blend of satellite, ship, and buoy observations. The datset spans 1 January 1982 to present with a 1 to 2-day lag from the current day. Data are preliminary for about two weeks until a finalized product is posted by NOAA. This status is identified on the maps by “[preliminary]” appearing in the title, and applies to the time series as well. SST anomalies, which are included in the OISST dataset, are based on 1971–2000 climatology. The time series chart displays area-weighted means for the selected domain. For example, if World 60S-60N is selected, then each daily SST value on the chart represents the average of all ocean gridcells between 60°S and 60°N across all longitudes, and accounts for the convergence of longitudes at the poles. Hide or display individual time series by clicking the year below the chart; Hide All and Show All buttons are at the chart lower right. The map can be switched between SST and SST anomaly by clicking the toggle button at the map top-left. A sea ice mask is applied to the SST and anomaly maps for gridcells where ice concentration is >= 50%

The North Atlantic still has a fever on 4 July. Warmer than usual water flooding up around southern Greenland right up to the edge of the melting sea-ice, with what looks like cold fresh meltwater flowing out of Baffin Bay along the west side.
Note that the ocean surface temperature is 5 °C right up to the edge of the sea ice, with warmer water than that intruding nearly as far as the ice front in Baffin Bay. Cooler water may be flowing out close to the Canadian shoreline. There is no sign in either of the SST maps of ‘cool spots’ which are thought to be the sources of the ‘salty cold water’ forming the deep water branches of the thermohaline circulation in the North Atlantic. In fact, the ocean in these areas seems to be 10-15 °C. Northern Hemisphere ice extents are low for the date but not yet near record lows, unlike the South!

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

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

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

Jet streams
Fig. 10a. Jet streams in the Southern Hemisphere.
Fig. 10b. Jet streams in the Northern Hemisphere
Fig. 10c. Global distribution of jet streams.
Jet streams are the atmospheric equivalents to major ocean currents that influence all of the other weather systems on the planet to keep them moving latitudinally around the planet. They are driven by temperature differences between the tropical and polar regions of the Earth and Coreolus effects as winds blow towards or away from the poles. Where the temperature differs strongly between poles and equator the jet streams are well organized with high winds. As temperature differences decrease so do the wind speeds, and the streams begin to slowly meander until they may become quite chaotic. Winds less than 60 kt are not considered to be jet streams. At present (as shown in Fig 8b, there are virtually NO jet streams at all in the Northern Hemisphere, and the winds that do exist are completely chaotic — a highly unusual situation. This leaves major heat domes and cold patches basically motionless, facilitating the buildup of record temperatures.
Fig. 11. The taiga is found throughout the high northern latitudes, between the tundra and the temperate forest, from about 50°N to 70°N, but with considerable regional variation. (Wikipedia).
Some of the greatest impacts of the disrupted jet stream system are seen over the boreal/taiga forest zones of North America and Eurasia. Arctic tundra and much of the taiga is underlain by carbon rich peat and peaty permafrost soils that are thought to contain at least 2x more carbon than the current amount of carbon in our atmosphere. Depending on circumstances, significant amounts of that carbon can be released in the form of methane, that has more than 80x the greenhouse potential of CO2 over the first 20 years of emission (20x over 100 years).
Fig. 12.By the end of June Canadian wildfires mainly in boreal forests have burned more area before the fire season is half over than in the previous record for a full year in 1989. Phys Org (30 June 2023). As at 6 July 8.782,952 have burned (Canadian Interagency Forest Fire Centre).
If the burning releases more greenhouse emissions than can readily be recaptured by re-vegetating forests. These emissions may more than replace any emissions humans cut — providing positive feedback to drive global temperatures still higher. This is one of several crucial tipping points associated with stopping the thermohaline circulation.
Intensity of observation
A hint to how little you can trust claims of reality denying trolls, puppets, and the like, is provided by the number monitoring points that physically monitor the atmosphere at those locations around the surface of the planet we live on used PER DAY.
Atmospheric monitoring
The European Centre for Medium-Range Weather Forecasts (ECMWF) for the charts plotted on 6 July 2023 as shown below are based on measurements from 92,702 locations. Note 1: this map does not NOT include ocean monitoring points. Note 2: The DATA COLLECTED EVERY DAY by this web of sensors is available to, used, and interpreted by several different national and institutional climate monitoring centers. In other words, the conclusions are cross checked between different centers many times over. The charts above depict scientific facts, not hunches and personal opinions. For more detail on how the accuracy of the observations is controlled see ECMWF’s Monitoring of the observing system.
Fig. 13. This chart maps the type and location of 92,702 separate observations used on 6 July 2023 between 3:00 and 9:00 PM for 6 hourly data coverage used by the ECMWF data assimilation system (4DVAR). Each plot shows the available data for a family of observations. The current day’s chart can be downloaded here. SYNOP refers to encoded information collected and transmitted every 6 hours by more than 7600 manned and unmanned meteorological stations and more than 2500 mobile stations around the world and is used for weather forecasting and climatic statistics. SHIP METAR is a format for reporting weather information. A METAR weather report is predominantly used by aircraft pilots, and by meteorologists, who use aggregated METAR information to assist in weather forecasting.
Oceanographic monitoring
Argo
Argo floats profiles physical properties of the surrounding water, minimally ocean temperature, salinity, pressure (i.e., depth). Each float operates on a 10 day cycle, spending most of the cycle ‘resting’ at an intermediate depth. On the 10th day it sinks to a specified depth and begins recording inputs from its sensors as it floats up to the surface. The standard float sinks to a depth of 2 km (2,000 m) and records all the way up to the surface, where it then determines its GPS position to within a few meters and messages a passing relay satellite with its location and profile data before sinking to its resting depth waiting for the next profile position. As shown on the world map here, for June 2023, shows the locations of 3849 profiles received over the month. Of these ~1,400 recorded the profile from 2 km deep in the ocean to the surface. Some floats are designed to sink to the bottom and thus record a profile for the full depth of the ocean. A few include several additional sensors to levels for things like acidity, oxygen, nitrate, light level, and some more I don’t recognize. The Argo system is really quite amazing.
Some even have ice sensors allowing them to operate even in ice-covered waters by warning if they might be fatally damaged by striking ice overhead. For these, if they sense ice, they’ll record the profile in memory, and drop back and rest until the next cycle (which may again prevent surfacing). These interrupted cycles will keep repeating until the float can safely surface — in which case all of the aborted profiles will be messaged to the satellite relay along with the current one (better late than never!)
And then there is a plethora of other ocean sensor systems. The full gamut of them shown next. The various different types are named in the legend. Collectively, on 26 June 2023, the ocean sensing system measuring in-situ variables includes 7973 ‘platforms’ (including the different kinds of Argo Floats) and results from 104 ‘cruises’ of ships ranging from specialized oceanographic vessels to fishing boats. Some of these non-Argo systems also record partial or complete (i.e., to the bottom) profiles.
Almost all of the data collected from the range of sensors is freely accessible via the public World Wide Web.
Fig. 15.
Satellite remote sensing systems
As if the plethora of physical systems for directly measuring weather and climate is not enough. There is now a cloud of satellite-based remote sensing systems buzzing around our planet, making literally millions of observations every day of critical weather and climate variables. NASA EarthData’s What is remote sensing? gives a high level overview of some of the capabilities of these systems. You can be assured that the measurements made by the earth-based and space-based sensing systems are carefully cross calibrated to ensure the various systems are all working together towards a common view of the actual physical reality.
Major heat engine domains of the Earth System
Dynamic changes in the Universe through time are driven by spontaneous flows and transformations of energy from ‘sources’ at high potential to entropy and ‘sinks’ at lower potentials (e.g., water flowing down a hill). This flux can be used to drive other processes through a system of coupled interactions forming a thermodynamic system or heat engine. As governed by the universal physical Laws of Thermodynamics (especially the Second Law), as long as there is a potential difference between source and sink, the flux of energy between them will continue to spontaneously flow through the system/heat engine as long as long as the system’s net entropy production remains positive.
The ‘Earth System’ includes all the shell-like layered components of the planet from the edge of outer space to its center. The three main ones concerning us here from inside out are the geosphere, hydrosphere, and atmosphere. The biosphere formed in the interface between atmosphere and geosphere (on the planetary scale) is a microscopically thin turbulent layer of carbonaceous macromolecules and water combined with other elements and molecules exhibiting the properties of life. We humans form part of that biosphere.
The heat engines described here circulate masses of matter that transport heat energy from place to place within the Earth System.
Geosphere
The geosphere comprises Planet Earth’s, solid (‘rocky’) components. The geosphere’s heat engine is based on the geologically slow process of plate tectonics that drives continental drift.
Fig. 16. Geological heat engine at work. Mantle convection may be the main driver behind plate tectonics. Image via University of Sydney.
The plate tectonics engine is driven by the slow radioactive decay of unstable isotopes of elements such as potassium, uranium and thorium remaining from the formation of Earth some 4.5 billion years ago.
Enough heat has and is being generated by this decay to melt the planet’s core and heat and expand the overlying mantle rocks enough to make them less dense and plastic enough for them to form convection cells like you see in a pan of nearly boiling water. Hotter and less dense rocks float up towards Earth’s harder crust and spread out (carrying surface crust and even lighter continental rocks, i.e., ‘plates’) to become cool enough for gravitational force to pull the solidified plates back towards the molten core in subduction zones that also form oceanic trenches.
Heat transported from radioactive decay is released into the hydrosphere and atmosphere from conduction through the crust + hot springs and geysers; by molten basalt lava coming to the surface in oceanic and terrestrial spreading (‘rift zones’); and volcanoes associated with localized ‘hot spots of rising magma or with the rift zones. Lavas associated with the latter type of volcanoes are formed of lighter, lower melting point rocks forming a scum on top of the denser crustal rocks of the drifting plates.
Hydrosphere
Earth’s hydrosphere is the thin film of water between the geosphere and atmosphere forming the salty Ocean covering around 70% of the planetary surface along with lakes and streams of generally nearly salt-free water serving as feeding tendrils draining water condensed from the land. The hydrosphere also includes a solid component of ice and a gaseous component of vapor. These components have very different properties compared to water and each other.
The liquid component of the hydrospheric heat engine absorbs solar energy in the form of heat warming volumes of water, in the form of latent heat of fusion (i.e., melting of ice) absorbing about 80 cal/gm of ice melted, and latent of vaporization (i.e., turning liquid water into an atmospheric gas) absorbing about 540 cal/gm of water vaporized (6.75 times as much energy as required to melt the gm of ice). The heat absorbed becomes ‘latent’ in that the energy transforms the state from liquid to solid or from liquid to gas without changing the measurable or feel-able (i.e., ‘sensible’) temperature of the mass. When the water vapor condenses or the water freezes, of course the latent energies are released in the form of sensible heat.
Basically, the hydrospheric heat engine is driven by the absorption of excess amounts solar radiation (the source) in equatorial, tropical, and subtropical regions of the planet that is mainly carried by ocean currents towards the polar and sub-polar regions where the an excess of heat energy released from water and freezing ice is carried away from the planet in the form of long-wave infrared radiation to the cold sink of outer space. Many different local, regional, and global ocean currents are involved in moving energy around the planetary sphere. Proportionately, a small amount of geothermal heat energy is absorbed from the geospheric heat engine by water, and larger amounts of heat are exchanged with the atmospheric heat engine(s) in a variety of ways.
Water has some very peculiar properties that play very important roles in the climate system and biospheric systems, especially around the freezing point. Most materials contract and become denser as they cool. This is also true for pure water, down to a temperature of 4 °C when it begins to expand and become less dense until it begins to freeze. Ice at 0°C is even lighter such that it easily floats. This is because water molecules are shaped like boomerangs with the oxygen atom at the apex and the two hydrogen atoms sticking out at angles. When they are warmer they jitter around in a relatively random way, such that warming makes the molecules jitter faster and further, while as they cool the jitter slows and they come closer such that a given number of molecules take up less space. As the jitter slows further at and below 4 °C, molecules tend to spread out some to form a quasi crystalline structure approaching that of ice where they are more or less locked into that structure, where the solid water is significantly lighter than the liquid. The presence of dissolved salts and minerals depresses the freezing temperature. As as ice freezes, crystallization of the water also tends to concentrate and expel dissolved minerals and gases in extra-cold plumes of particularly dense and very cold salty water (i.e., brine) — cold enough that tubes of ice may form from the less salty water around the brine.
Water is also a god solvent, able to carry substantial amounts of gases, (e.g., oxygen, CO2, methane – CH4), salts, carbonates, nitrates, sulfates, metal ions, etc). The ocean carries a lot of salt – enough to play an important role in the ocean circulation system. Oxygen and CO2 play essential roles in living systems, CO2 and carbonates play important roles in interactions between water, the Geosphere and the atmosphere. CO2 and methane in the atmosphere, along with water vapor, are the most important greenhouse gases, etc…..
Fig. 17. A summary of the path of the thermohaline circulation. Blue paths represent deep-water currents, while red paths represent surface currents. This map shows the pattern of thermohaline circulation also known as “meridional overturning circulation”. This collection of currents is responsible for the large-scale exchange of water masses in the ocean, including providing oxygen to the deep ocean. The entire circulation pattern takes ~2000 year. Wikipedia
The principal current system driving ocean heat transport is known as the ‘thermohaline circulation‘. Basically, seawater is warmed in the equatorial, tropical and subtropical regions of the world. It also increases in density due to the evaporation of water vapor into the atmosphere. However, parcels of water are kept hot enough that thermal expansion more than compensates for the densification from becoming saltier. However, as currents carry the hot, salty surface water further towards the poles, the water begins to cool until the warm salty water carrying a full load of oxygen becomes dense enough around 4 °C to sink through layers of still warmish but less salty water, carrying a full load of oxygen down to the bottom of the ocean. The salt in this descending water is diluted by mixing with relatively fresh ice water from terrestrial runoffs, melting glacial and sea ice, etc sourced from zones even closer to the poles than where the dense salty water normally sinks.
The main source of power that drives the thermohaline circulation heat engine is the conversion gravitational potential energy in the sinking masses of water as they sink to the ocean floor this sinking helps to pull surface waters into the ‘sinkhole’. Further assists to the circulation are provided by prevailing atmospheric winds pushing surface waters away from continental shores, pulling up cold, deoxygenated, CO2 and mineral rich deep waters to the surface where they fertilize the blooms of micro-algae that add more oxygen and feed the whole food chains of larger organisms in the oceans.
Atmosphere
Fig. 18. (top)Plan and (bottom) cross-section schematic view representations of the general circulation of the atmosphere. Three main circulations exist between the equator and poles due to solar heating and Earth’s rotation: 1) Hadley cell – Low-latitude air moves toward the equator. Due to solar heating, air near the equator rises vertically and moves poleward in the upper atmosphere. 2) Ferrel cell – A midlatitude mean atmospheric circulation cell. In this cell, the air flows poleward and eastward near the surface and equatorward and westward at higher levels. 3) Polar cell – Air rises, diverges, and travels toward the poles. Once over the poles, the air sinks, forming the polar highs. At the surface, air diverges outward from the polar highs. Surface winds in the polar cell are easterly (polar easterlies). A high pressure band is located at about 30° N/S latitude, leading to dry/hot weather due to descending air motion (subtropical dry zones are indicated in orange in the schematic views). Expanding tropics (indicted by orange arrows) are associated with a poleward shift of the subtropical dry zones. A low pressure band is found at 50°–60° N/S, with rainy and stormy weather in relation to the polar jet stream bands of strong westerly wind in the upper levels of the atmosphere. From Wikipedia Hadley Cell.
The atmosphere includes the gaseous components of Earth’s global heat engine. The transport and transfer of heat energy and the Coriolis effect are the major drivers. The major sources of heat are direct conduction of sensible heat across the atmosphere : ocean/land interface, the conversion of latent heat into sensible heat through the evaporation and condensation of water vapor (mainly from the oceans), and direct solar heating (note: because the atmosphere is largely transparent to most radiation, most solar energy is not captured by the atmosphere itself.)
The diagram here shows how the transport of heat from the Earth’s surface to the top of the atmosphere where it radiates away as infrared to the heat sink of outer space organizes the wind systems into three major cycles. Note that the moisture laden warm air cools as it rises and releases a lot more energy as the water vapor condenses into rain or hail to keep the rising air warmer for longer.
Biosphere
The Biosphere (“Life”) – the totality of the living components of the planetary sphere, generally residing in the interface between the Atmophere and the Geosphere/Hydrosphere, where living things are characterized by their capacity to self-organize, self-regulate, and self-reproduce their properties of life through time.
The “Engine of Life” is predominantly driven by the complexly catalyzed formation of high energy chemical bonds from the capture of solar radiant or activation energy from redox reactions to combine oxygen and carbon to produce high energy carbohydrates used or ‘burned’ to fuel all kinds of metabolic activities and processes in living things. Living components of the Earth System have and depend for their continued survival and reproduction on their capacity to catalyze all kinds of energy transformations within and between the other Earth Systems. Over time the Engine of Life has profoundly affected the other planetary spheres.
Over evolutionary time the emergence and evolution Life has affected major global transformations involving many aspects of Earth’s other subsystems. Evolutionary processes are complexly dynamic and many of them include many potentially powerful positive feedbacks able to drive changes at exponential rates. All life can evolve genetically to live under a wide variety of environmental conditions over multi generational time scales due to natural selection at the genetic level.
A few species and humans in particular, can evolve culturally at intra-generational timescales to drive changes at exponentially explosive rates to the extent that WE are literally threatening all complex life on the planet with global mass extinction – quite possibly within two or three of our own generations!
Interpersonal competition to gain ever more personal power from the burning of globally significant quantities of fossil carbon in less than a century that was accumulated in the geosphere over millions of years by life processes has destabilized Earth’s Climate System. TODAY, we seem to be in the midst of flipping the global climate system from the Glacial-Interglacial Cycle most life has adapted genetically to live under, to the Hothouse Earth regime that very few organisms will be able to survive in without hundreds or thousands of generations or more of genetic adaptation.

The oceans are record warm while heat waves have invaded multiple continents and ice levels are at historic lows.
Spring has only just begun to transition to summer in the Northern Hemisphere, but some of the season’s most odious and dangerous extreme weather is already running rampant.
Prolonged and punishing heat waves in Asia have sent temperatures soaring to 100 degrees as far north as Siberia and above 110 degrees in Thailand and Vietnam, breaking records.
Wildfires are raging in Canada, which has never seen so much land burn so early in the year. They come after a record-warm May.
Extreme conditions extend to the Southern Hemisphere too, where record warmth and historically low sea ice levels linger even as that part of the globe enters winter.
The extremes are all connected to ocean waters that have hovered at record-warm levels for months, boosted by human-caused climate change. The weather chaos could escalate in the coming months as summer temperatures peak and a developing El Niño elevates air and water temperatures worldwide further.
And then the 2020 wildfires on the Siberian permafrost and taiga as summarised by Hall 2020:
Apparently the situation this year in early June, which is still very early in the normal temperate and subpolar climate zones of the Northern Hemishere, is already significantly worse than either the whole years of 2016 and 2020.
Where climate change is concerned, in 2023 before the year is halfway finished, indicators of the progress of global warming are already of the map into previously uncharted territories.
This post here only adds to alarms being set off by Climate Sentinel News‘s posts of the last few days (click thumbnails to read the posts):
What can we do to turn off the road to extinction in Hothouse Earth before it is too late?
In a few days VoteClimateOne.org and affiliated organizations will be launching our “Tools for Changing Government Minds”. The need for change is too urgent to depend on replacing people in office. Instead we have to change the minds of the existing people in office. Our launch document(s) will provide access to the tools, explain how to use them, and provide an armory full of nuggets of knowledge to be used as ammunition.
The first nugget to be fired at your local representative from as many different sources as possible is: (again click the thumbnail to open the file):
We need climate emergency action now! to get it started email the link to or post a copy of the document above to your federal and state MPs and senators with your own comments: If they don’t immediately start acting on the climate emergency that they will be history come the next election. Actions must include declaring (or passing legislation) that they recognize that we have to fight an existential emergency and all parliamentarians must get off their arses to shut down all sources of carbon emissions and begin mobilization to develop genuinely globally scalable technologies for capturing carbon from past emissions and safely sequestering the captured carbon in soils or in the deep oceans.
You can start doing this today if you want. You are welcome to link to or download and print any of the Climate Sentinel News posts that will help drive home the points you want to make in your cover note.
The basic idea of the campaign is very simple.
What politician is going to continue working as a puppet for special interests against first a few letters on the climate action theme, then tens, then hundreds, thousands, tens of thousands and possibly even hundreds of thousands specifically addressed to him/her with the message act or else…… The mailing lists exist, we are crafting proforma covering documents, etc..

Human activities are triggering self-reinforcing existential climate risks that are growing more lethal with time — our extinction is likely
Over the last 200 years prodigious amounts of carbon-based fossil fuels (coal, oil, methane) have been burned to produce waste gases (mostly CO₂) and useful energy to drive the Industrial Revolution, our affluence, our toys, our technologies, our wars, and everything that has followed. The fossil carbon humans have extracted from the Earth and burned in an instant of geological time took our planet millions of years to accumulate and store in the geosphere (i.e., rocks & soil). In the same geological instant, the waste gases released from the burning are fundamentally changing Earth’s atmosphere (the air we breathe, etc…). Because of the physical properties of CO₂ molecules and other atmospheric emissions, this has trapped enough additional solar heat in the atmosphere to significantly raise average temperatures around the world. In turn, the added heat is already causing unprecedented climatic disasters. These existential climate risks will only become more frequent and catastrophic as temperatures continue to rise. (See CO2: Past, Present, & Future – one of many dozens of articles covering the same facts, and Climate apocalypse).
However, natural regulatory processes in the climate system have kept the environment stable enough for more than 800,000 years up until the 20th Century – enough time for humans to evolve and develop the social systems, agriculture, technology, and cultural riches we benefit from today.
Atmospheric CO2 levels (blue line) and temperature (red line) from year 1,000 to 1978. Data for CO2 from Vostok ice core, Law Dome ice core, and Mauna Loa air samples. Data for temperature from Vostok ice core. CO2 measured here is in parts per million (ppm = by weight), which is similar to ppmv (by volume).
As shown in the graphs above, the shock to the composition of the atmosphere caused by these human generated changes is increasingly disrupting natural climate regulation. If we do not quickly stop and repair the damage we have done to the atmosphere, then over the next few decades increasingly extreme, frequent and extensive climate changes and catastrophes will be causing more death and destruction to our societies than we have the capacity to repair. In turn, this climate collapse will lead to agricultural, economic and social collapse followed by mass die-offs and probable human extinction within a century or two.
Business as usual cannot cope with a global systems breakdown. Nor can uncoordinated individual actions. However, at least for a few more years before systems breakdown has progressed too far, we should still be able to assemble the technology and knowledge to avoid this doom. Beginning with primitive Victorian era steam-punk technologies backed by a very limited scientific understanding of climate and geophysics, humans took over 150 years to burn enough fossil fuel to accidentally cause the present crisis. Today we have now developed a deep and detailed scientific understanding of how the world works and vastly more powerful technologies. With will, leadership, and cooperation at international, national, state, and local areas we should be able to locate, diagnose and repair aspects of the climate system we have broken to re-stabilize it in a state we can live with.
However, to do this we will have to revolutionise many of our governments. We need to change them from their usual businesses of representing and working for the special interests of their donors, patrons and puppet masters (many of them associated with fossil fuel industries), to a new business of truly representing the needs of the citizens they supposedly represent – – especially in the face of the growing climate crisis.
If you are an MP, you need to join this revolution!
The factual scientific evidence of the consequence we face if we fail to stop and reverse global warming is overwhelming. However, I recognize that a life in politics where almost everything can be ‘negotiated’ does not prepare most politicians to understand the difference between responding to non-negotiable facts of physical reality and the business-as-usual of getting elected/re-elected and trading influence.
In the remainder of this work I present some of the overwhelming evidence of the dangers we face from an increasingly destabilised climate system driven by unrestrained global warming, and why our governments must change and act if we are to have any hope of surviving the existential global crisis this is causing. Because this evidence is based on scientific laws developed over some 400 years of testing and practical use, it is totally independent of whatever people might want to ‘believe’ now about how the world works.
Laws of physics, geology, chemistry and biology
The scientific laws of physics and chemistry describe how the universe we live in works, irrespective of anything we humans might want to believe. Because atoms and molecules work the way they do, burning carbon releases ‘greenhouse’ (i.e., heat trapping) gases into the atmosphere. Because the increased concentration of these gases in the atmosphere traps reduces the amount of solar energy leaving our planet, the world is growing warmer.
It should be no surprise that dumping millions of years worth of carbon accumulation into the atmosphere as greenhouse gases at an accelerating rate over 200 years or so has significantly affected global temperatures.
Berkeley Earth’s Global Temperature Report for 2022 – Posted on by Robert Rohde. The global mean temperature in 2022 is estimated to have been 1.24 °C (2.24 °F) above the average temperature from 1850-1900, a period often used as a pre-industrial baseline for global temperature targets. This is ~0.03 °C (~0.05 °F) warmer than in 2021. As a result, 2021 is nominally the fifth warmest year to have been directly observed, though the years 2015, 2017, 2018, 2021, and 2022 all cluster closely together relative to their uncertainty estimates. In particular 2022 and 2015 are essentially tied, and 2022 could just as easily be regarded as the 6th warmest year. This global mean temperature in 2022 is equivalent to 0.91 °C (1.64 °F) above the 1951-1980 average, which is often used as a reference period for comparing global climate analyses. The last eight years stand out as the eight warmest years to have been directly observed. (Note: Berkeley Earth’s methodologies and their differences from other groups providing similar global temperature records are described here.)

Credit: NOAA/NCEI World Ocean Database. A more detailed graph including additional measurements from instrumented mooring arrays, and ice-tethered profilers (ITPs) covers the period 1992 – 2022. Credit NASA ECCO. Covering more than 70% of Earth’s surface, our global ocean has a very high heat capacity. It has absorbed 90% of the warming that has occurred in recent decades due to increasing greenhouse gases, and the top few meters of the ocean store as much heat as Earth’s entire atmosphere. Note: If you want to grasp how many and what kinds of precision measurements – cross-checked across a variety of measurement platforms go into constructing these graphs, I suggest taking the time to go through one of ECCO’s presentations: ECCO: Integrating Ocean and Water.
Water (= H₂O) is a major component in the climate system and the main carrier of energy driving weather and climate change.
Each of water’s three physical states: water vapour (=gas), liquid water, and frozen water (=ice), together with transitions between the three states, all play important roles in the absorption, storage, transport, and release of heat around the planet. In its own right water vapour is also the most important and variable greenhouse gas.
Of all the natural materials forming the outer layers of the Earth, water has the second highest heat capacity of any known chemical compound. A lot of energy needs to be absorbed or released to warm or cool a quantity of water by even one degree — the amount of heat needed to raise the temperature of 1 gm water by 1 °C at standard pressure and temperature has its own name, the calorie. (An old unit of measure, but the easiest to follow here.) This same amount of heat is released when the 1 gm cools by 1°. To raise the temperature of 1.3 sextillion litres just by 1° of the world’s oceans takes the absorption of a humongous amount of heat!
Water (Hydrosphere) and Air (Atmosphere)
Water in the world Ocean
At temperatures above 4 °C, water expands as it warms. In other words, a parcel of water composed of a given number of molecules occupying space expands in volume as it warms from 4 °C to boiling. Thus, as the ocean warms, sea levels rise. Water running off the land from melting glaciers and ice sheets causes sea levels to rise further and faster.
Warmer waters lying over cooler waters of the same salt content tend not to mix. However, as warm salt water evaporates, salt is left behind, making the remaining surface water denser, until it becomes heavier than cooler water below, allowing the warm water to sink and mix with the cooler water. This helps to suck in ocean currents to replace parcels of the cooling saltier water as they become denser and sink into the depths.
Thus, ocean currents are important engines for transporting heat around the globe.
Water in the atmosphere
Boiling or evaporating 1 gm of liquid water to gas (i.e., invisible steam) at one atmosphere of pressure takes approximately 540 calories of energy (= ‘heat of vaporisation/evaporation‘)! Similarly, when H₂O gas condenses to form visible steam (i.e., a mist of liquid water) the same energy of vaporisation is released as heat.
When liquid water freezes to form solid ice it releases ~80 calories/gm, while 80 calories of energy needs to be extracted from the surrounding environment to freeze 1 gm of liquid water to ice.
The gas laws discovered in the 1800s through practical experience with the thermodynamics of steam and internal combustion engines govern the relationships between temperature, volume, and pressure of gases. As heat energy warms a parcel of gas at a standard pressure, the absorbed energy causes the gas molecules comprising the parcel to move faster – resulting in increased volume (lowering the density of the parcel compared to surrounding parcels that have not changed in temperature). Or, vice versa increasing pressure will cause the gas parcel to heat up. Similarly, cooling gas will shrink in volume (i.e., become more dense) as its temperature decreases, or warming gas will increase its volume becoming less dense as it is heated. This is why parcels of warm air tend to rise in generally cooler air and vice versa.
Finally, another set of laws describes the solubility of water vapour in Earth’s atmosphere, and the solubility of the various gases forming the atmosphere in water. A parcel carrying the maximum concentration of a dissolved material is said to be ‘saturated’. Normally any excess over the point of saturation is precipitated out of the solution. Where precipitation of water vapour in the atmosphere is concerned, the precipitated water is called dew (if it collects on a surface), mist (if the droplets are small enough to remain floating in the atmosphere), rain (if droplets are large enough to fall to the ground) or snow (if it is cold enough for the precipitation of solid water). Hail is precipitated as liquid droplets that coalesce and freeze on the way to the ground. Basically, the capacity for the atmosphere to carry water as dissolved water vapour and the rate at which the vapour evaporates from the liquid increases substantially with temperature.
Note that the process of evaporation absorbs a lot of energy (i.e., the vapour stores the energy that drove the evaporation as latent heat) which is released as sensible heat when the dissolved vapour condenses and precipitates. Warm air can hold a lot of water vapour while cold air can only hold a little vapour. Thus a warm air mass is often able to suck moisture out of vegetation and soils, but as that mass rises in elevation and cools a temperature may be reached where the air is saturated (this is called the ‘dew point‘) and possibly massive amounts of water are precipitated as rain or snow together with the release of huge amounts of latent heat as sensible heat causing the air mass to rise still higher (e.g., into towering anvil topped cumulonimbus clouds). The rising air is liable to suck in high speed winds and possibly even form small and large hail, cyclones, and tornadoes. The higher the temperature of the air mass is when the dew point is reached, the more precipitation, heat and wind is generated.
As global warming increases baseline and average temperatures around the world, the amount of energy contained in parcels of water vapour increases, and thus increases the total amount of energy available to drive extreme weather events.
Water on the land and in the biosphere
Liquid water is a powerful solvent for all kinds of minerals and flows downhill wherever it can. Flowing water is relatively dense, and therefore an important agent for the transport of solid materials ranging from particles of sand to potentially huge boulders and even buildings. Consequently, standing and flowing waters are the major agents of dissolution, erosion and storm damage: especially when combined with storm-force winds.
All living things on Earth are partially comprised of water, with humans being about 60% water and even trees 50% water. The water in and around living things acts a) as a solvent and as a medium of transport for the dissolved gases required for photosynthesis (where this exists) and respiration; b) as a medium of transport for the ions, molecular nutrients and waste products of cellular metabolism and growth; c) as a structural element in the three-dimensional folding of proteins and other macromolecules; and d) as a structural element in the maintenance of hydraulic rigidity of the shapes of cells and vesicles, and even whole organisms.
Every type of living thing requires the availability of a minimum amount of water of a minimum quality to survive. Conversely, too much water and/or water of the wrong quality (i.e., it may be transporting harmful substances as particles or in solution) or wrong temperature (i.e., the shapes and activities of proteins involved in metabolism unavoidably change with changing temperature) may also kill.
Air in the water
Atmospheric gases (e.g., nitrogen, oxygen, carbon dioxide) are more soluble in cold water than warm water. In other words, cold water can carry a lot more dissolved O₂ and CO₂ than warm water can.
CO₂ is relatively soluble in water because it readily forms carbonic acid. This is important for global warming because the oceans currently absorb about 30% of all global CO₂ emissions, thus slowing the rise of global temperatures due to the greenhouse effect. However, this is bad news for life on Planet Earth for three reasons: First, as the gas is increasingly absorbed into the water some of it turns into carbonic acid. This makes the water more acidic, dissolving calcium from shells and bones – contributing to the die off of plankton, corals, shellfish and bony fish. Secondly, given that CO₂ is the waste product of respiration it slows the respiration of all marine and aquatic organisms. Three, as water temperature rises CO₂ becomes substantially less soluble. This can be catastrophic for global warming because it acts like a time bomb. Rising temperatures drive significant amounts of CO₂ out of solution in the ocean, back into the atmosphere, where it acts as a positive feedback driving global temperatures still higher in a potentially vicious cycle.
O₂’s solubility in water is limited, but dissolved O₂ is critical to life for all complex organisms that respire water. This includes all aquatic or oceanic organisms: many bacteria, most protozoa, single-celled and multicellular algae (net O₂ producers by day, overnight they must extract O₂ at night for respiration) up to whole forests of giant kelp, giant squids, whale-sharks, and the largest whales. In the pre-industrial world O₂ levels in most waters were close to saturation. Any degree of warming beyond what species are adapted to live in reduces the amount of O₂ the water can carry. Species will begin dying when the O₂ levels fall below levels the different species have evolved to tolerate. For example, along the Southern California coast where I grew up, whole forests of giant kelp die off when the ocean temperature rises to around 23 °C. So do the myriad of other species living in those forests that may still be able to respire, because at some to many points in their lifecycles they required something the kelp provided. Other kelp forests around the world, and in Australia are also dying off, e.g., the once rich kelp forests of Tasmania – possibly even more comprehensively than they have in California (e.g., northern Tasmania).
And then there are the horrific die-off events in the rivers and lakes of Australia’s Murray-Darling region, where the combination of blistering heat combined with off-the-charts CO₂ levels is absolutely lethal to whole ecosystems. This year’s event even killed carp that can breathe air!
How will our Atmosphere, Hydro-/Cryo-sphere, Geosphere and Biosphere respond to global warming on the real Planet Earth?
Meteorology, climate science, earth systems science extend the basic laws of physics, chemistry and a little bit of biology into the real world. However, even a brief review of some of the basic laws of physics and chemistry above for water, oxygen, and CO₂ gives some hint of just how complex weather and climate change really are. Earth’s Climate System that generates weather and climate change in the world we live in is a complex dynamical system composed of probably hundreds of variables often interacting with one another in non-linear. Some of these interactions are poorly understood or even unrecognised even by the scientists studying them.
Even though the Earth System is absolutely and fundamentally governed by the physical laws of nature, trying to predict future weather and climate conditions is fraught with difficulties of two kinds. First, complex systems of many variables, where some of the variables have non-linear positive feedback relations with one another, often behave chaotically under some or even many conditions. (See also climate change feedback.) Second, is that some of the variables are probably still unknown to science or not well understood. Even the largest supercomputers in the world capable of performing more than 100 quadrillion calculations per second and working with millions of daily observations from around the world can only make usefully accurate weather predictions out to around 8 days before wandering off into random noise.
For these reasons, predicting the future trends of global warming with a high degree of accuracy and certainty is frankly impossible. However, what is almost certain is that if we do not stop and reverse the process of global warming there will be major disruptions to all of these systems which will make much of the Earth uninhabitable for complex life.
How trustworthy are the sciences and the warnings?
The UN’s Intergovernmental Panel on Climate Change (IPCC) deals with the uncertainties by running large numbers of similar earth/climate system models (ensembles) with slightly varying inputs on supercomputers to forecast possible future trends and their likelihoods. These outputs are analysed statistically to determine frequent trends and the range of uncertainties around these trends. Thus, many believe that the models give us a relatively good idea of how changes in specific environmental variables are likely to change the climate.
Unfortunately, with regard to managing climate risks, the reality is that this approach is too conservative because:
Most scientists agree that the RATE of climate change is increasing with time. However, the delays in knowledge flow between observation of reality and assessment and presentation of results mean that there is a lag built into the IPCC reports. That is, the delays inherent in analysing and writing up the results, delays in conducting peer review and publishing the original research, conceiving and constructing and running the mathematical models based on those results to forecast the future, analysing and writing up the results of the modelling, delays in publishing these results; and then comes the added time cost to incorporate the published results in an IPCC Report. This IPCC process alone takes a minimum of 2-3 additional years of three drafts, two peer reviews, and a final sign-off by the political appointees of the 170 countries comprising the UN’s World Meteorological Organization. Thus, the years-old input data providing a baseline for the models’ predictions necessarily do not include the array of record-breaking temperature, greenhouse gas, and weather readings associated with the increasingly extreme weather events of the last few years.
Finally most IPCC scientists are associated with academic and research institutions funded by governments, where academic progress and promotions depend on not being too novel or controversial (i.e., exhibiting ‘scientific reticence‘). This leads to scientific self-censorship — downplaying alarming findings, reinforced by the need that IPCC Reports require political approvals by government appointees to be published.
The following graphic is the IPCC’s own depiction of their authoring and review process.
The graphic and a comprehensive description of IPCC’s writing and review processes are given in their document, Preparing Reports. In turn, even more detail on how each kind of document is prepared, reviewed and signed off is provided in the IPCC [Documentation] Procedures, according to the thePrinciples Governing IPCC Work that lay down the role, organisation and procedures of the IPCC. These guiding Principles establish comprehensiveness, objectivity, openness and transparency for all IPCC Work .
Thus, when the formal IPCC reports publish their predictions for the future consequences: it follows that this is a gold-standard, scientifically correct but somewhat rose-tinted statement of the best possible outcomes we can hope for from the present state of the escalating climate emergency. The actual future is most likely to be worse, or even more worse.
Given all of these factors, it is virtually impossible that the IPCC reports are in any way overstating the magnitude and dangers of the climate crisis. Those who claim the IPCC reports are ‘alarmist’ are seriously misinformed or else aim to be deliberately misleading.
How do we know all of this?
There is a vast array of direct observational evidence from the real world (e.g., the graphs of increasing greenhouse gas concentrations and rising global temperatures presented above) showing that our global climate is already deteriorating at historically and even geologically unprecedented rates. A few recent observations sample this kind of evidence.
Identifying, analysing, and managing climate risks
Most climate scientists have backgrounds in mathematics, physics or geology where they are used to working with well behaved regular systems — not complex dynamical systems with potentially chaotic and unknown variables where the models are inherently fallible in their predictions of the future. Although the mathematical theory of chaos emerged from early attempts to model climate, few have any formal grounding in complex systems or chaos theory. Consequently, they tend to believe their models can predict the future with some degree of statistical accuracy, rather than accepting that models are good for explaining what can happen but not what will or won’t happen.
Scientists (including a few climate scientists) who continue to deny that current climate change is mainly due to human activity are often used to dealing with changes over long periods of time, where natural and well understood processes are more or less adequate to explain how climate has changed in the past. Many of today’s deniers formed their opinions years ago (e.g. 1980s) when even climate specialists actively debated the extent and causes of climate change. In people prone to denial, ‘confirmation bias’ then begins to reinforce conclusions, where data fitting their belief is eagerly accepted, but seemingly contradictory data is critically scrutinised and rejected.
Over time, with the overwhelming additional data supporting unnaturally accelerated climate temperatures on land, air and sea, almost all genuine climate scientists have come to conclude that human activities are in fact changing the climate. The holdouts are usually in those other disciplines that have a default assumption that natural processes always explain changes in climate.
And then, there are those who have totally unscientific reasons for denying that humans cause climate change.Following on my career as an evolutionary biologist (PhD Harvard 1973) with strong backgrounds in geology, physics, systems sciences (systems ecology, genetic systems, cybernetics), I was employed for 17 years as a knowledge management systems analyst and designer with what became Tenix and then Tenix Defence through the life-cycle of “Australia’s most successful naval surface combatant project – by far” – the ANZAC ship project. I worked very closely with the company’s engineering systems analysts and risk managers (often the same people did both). The ANZAC Project was so successful because the prime contract was performance-based rather than specifications based. We were contracted to deliver for a fixed price certain capabilities and reliabilities in service rather than meticulously detailed products.
Large defence systems – especially like warships and aircraft with their multitudes of subsystems, assemblies and piece parts, are complex dynamical systems that are inherently but unpredictably fallible due to unanticipated dynamics, human errors, or unpredictable failures of critical parts. It was the job of contract analysts, systems engineers, design engineers and knowledge managers (me), to work out a ship design and construction process that could be trusted to meet the customers’ requirements within the negotiated fixed price.
Failure Modes Effects and Criticality Analysis (FMECA)
The critical analytical tool in Tenix’s success, apparently unknown to climate science, is application of the Military Standard, Failure Modes Effects and Criticality Analysis (FMECA) within a risk analytical and management framework. Briefly, this involves (1) tabulating all conceivable failures and the potential consequence of the particular failure mode (i.e., its criticality) for every component of the system that might have a detrimental effect on the system’s safety or functionality, (2) preparing at least a matrix for every failure mode showing the approximate likelihood of failure, and (optionally) the likely consequences/costs to the system should the failure occur, and the costs to repair or mitigate the mode.
Applying FMECA to global warming
Should we ignore a risk because its consequences are so severe we fear accepting that it is real?
The following graphic plots an analytical matrix for the risk of human extinction from a failure to stop global warming at a safe global temperature for human survival. A serious analysis of this risk (that is unthinkable to many) demands examining the physical realities associated with each dimension of the matrix and looking for solutions to reduce consequences and likelihood of the risk happening, and to provide the maximum time possible to manage it; or alternatively, to entirely avoid the activities causing the risk. Unfortunately, given that the risk from global warming is associated with the project to power industrial, technological, and population growth by burning fossil fuels that began 150 years ago. Thus we have no choices but to live or die with the consequences arising from this project.
Our planning to manage the risk must consider the third dimension — TIME. How much time do we have to manage the risk if we are to avoid its consequences? The possible consequences of the risk are existential – i.e., extinction of human society as we know it or even the entire species. The probability is likely to be certain if we do not stop and reverse global warming. The timescale is imminent, i.e., within the expected lifespan of today’s children.
Should we heed the science and the warnings?
The Intergovernmental Panel on Climate Change was established by the United Nations to research and provide the “best” scientific advice available to governments of the world regarding the science, trends, and likely progress of climate change. The Panel’s staff is selected and overseen by all the member states of the World Meteorological Organization. The peer review is exhaustive and intensive – probably more so than for any other scientific endeavour ever.
For reasons I have detailed it would be virtually impossible for any formal publication of the IPCC to overstate the dangers represented by climate change. Where the IPCC says that even the current trends will be catastrophic if realised, I would say that they are ‘existential’: A word the IPCC rarely uses and never defines.
Existential risks are defined as “risks that threaten the destruction of humanity’s long-term potential.” The instantiation of an existential risk (an existential catastrophe) would either cause outright human extinction or irreversibly lock in a drastically inferior state of affairs. Existential risks are a subclass of global catastrophic risks, where the damage is not only global but also terminal and permanent, preventing recovery and thereby affecting both current and all future generations.Note: This discussion of definitions may seem to be highly pedantic. It isn’t. It is deadly serious. Humanity faces a serious risk of triggering a global mass extinction event akin to the End Permian event that was “Earth’s most severe known extinction event,[11][12] with the extinction of 57% of biological families, 83% of genera, 81% of marine species[13][14][15] and 70% of terrestrial vertebrate species.[16] It is the largest known mass extinction of insects.[17]” If you are declaring a state of emergency, it does not help to describe the emergency in soothing terms.
