Guardian: “A climate of unparalleled malevolence”: are we on our way to the sixth major mass extinction?

Essay by Eric Worrall

Apparently our pitiful atmospheric contribution is comparable to the 2 million year eruption which drove the Permian–Triassic Extinction, which wiped out most life on Earth.

‘A climate of unparalleled malevolence’: are we on our way to the sixth major mass extinction?

Churning quantities of carbon dioxide into the atmosphere at the rate we are going could lead the planet to another Great Dying

Put enough CO2 into the system all at once, and push the life-sustaining carbon cycle far enough out of equilibrium, and it might escape into a sort of planetary failure mode, where processes intrinsic to the Earth itself take over, acting as positive feedback to release dramatically more carbon into the system. This subsequent release of carbon would send the planet off on a devastating 100-millennia excursion before regaining its composure. And it wouldn’t matter if CO2 were higher or lower than it is today, or whether the Earth was warmer or cooler as a result. It’s the rate of change in CO2 that gets you to Armageddon.

Here’s a plausible sequence of events at the end of the Permian. First, and most simply: the excess CO2 trapped more energy from the sun on the surface of our planet – a simple physical process that was worked out by physicists more than 150 years ago. And so the world helplessly warmed – models and proxies both point to about 10C of warming over thousands of years – pushing animal and plant physiology alike to their limits. It’s also a simple physical fact about our world that for every degree it warms, the atmosphere can hold about 7% more water, so, as the temperature climbed and the water cycle accelerated, storms began to take on a menacing, drowning intensity. As the ocean warms as well, it holds less oxygen.

Now let’s pull back from the brink. However similar to this era our modern experiment on the planet might first appear, it’s worth acknowledging, even stressing, that the end-Permian climate catastrophe was truly, surpassingly bad. And on a scale unlikely ever to be matched by humans. Upper estimates for how much carbon dioxide the fossil-fuel-burning Siberian Traps erupted, ranging up to 120,000 gigatons, defy belief. Even lower estimates, of say 30,000 gigatons, constitute volumes of CO2 so completely ridiculous that matching it would require humans to not only burn all the fossil fuel reserves in the world, but then keep putting ever more carbon into the atmosphere for thousands of years. Perhaps by burning limestone for fun on an industrial scale for generations, even as the biosphere disintegrates. As it is, industrial civilisation could theoretically generate about 18,000 gigatons of CO2 if the entire world pulled together on a nihilistic, multicentennial, international effort to burn all the accessible fossil fuels on Earth.

Back in the real world, the Earth is still locked in a brutal Late Cenozoic Ice Age, which started 34 million years ago, yet still threatens to crush our civilisation under mile high walls of ice – so we have plenty of buffer between us and any kind of geologically significant global warming event.

Life has thrived under far higher CO2 levels than today. The graphic at the top of this page came from User-friendly carbon-cycle modelling and aspects of Phanerozoic climate change. During the late Carboniferous for example, CO2 levels were likely far higher than today, but despite elevated CO2 the Earth still experienced icehouse conditions, similar to today’s ice age cycle. So clearly CO2 isn’t the only factor driving climatic conditions.

The ice age of the last 34 million years is a lot of ice age. Clearly something more powerful than CO2 is keeping our planet locked in the ice box. It is likely industrial CO2 emissions will fail to overcome today’s geological ice box forcings, just as much higher CO2 levels failed to overcome the powerful geological ice box forcings which created the Late Paleozoic icehouse during the Carboniferous.

Even if I’m wrong, and substantial warming does occur, we have strong evidence humans would thrive in such conditions. Our monkey ancestors made their debut in the fossil record during much warmer conditions than today. The Palaeocene-Eocene Thermal Maximum, 5-8C hotter than today, was the age of monkeys. Our monkey ancestors thrived on the abundance of the hothouse PETM, and colonised much of the world, only retreating when the cold returned. If a bunch of monkey ancestors with brains the size of matchboxes could thrive in a much warmer world, then we humans certainly could – which gives us at least a 5-8C buffer of safety against any imaginable global warming event.

Fish also did well during the PETM – so it’s not just humans who would thrive in such warm conditions.

Given the remarkable stability of the Earth’s climate on geological timescales, the fact the Earth is still locked in an ice age, the benign conditions which prevailed in previous much warmer ages, and the existence of previous ice age epochs with far higher CO2 levels than today, those who focus on the carbon cycle alone are overlooking some pretty important evidence. Given all this, I believe we can reasonably conclude claims that industrial emissions are creating a man made Permian Extinction are an absurd fantasy.

I was wondering when we would be hearing another asinine doomsday prediction from The Guardian. Could it be that after a few drinks some of the equally asinine astronomers that they would employ to fabricate end-of-the- world scenarios mistook traffic signal reflections for an oncoming asteroid that will wipe out the remaining reptiles end civilization as we know it into the bargain?

Retail electricity prices have increased faster than the rate of inflation since 2022, and we expect them to continue increasing through 2026, based on forecasts in our Short-Term Energy Outlook. Parts of the country with relatively high electricity prices may experience greater price increases than those with relatively low electricity prices.”

I don’t see anything in your linked article that even intimates that Trump is responsible for the increasing electricity rates. It seems that almost everything he does is impeded by federal judges who impose stays on the implementation. Perhaps you should be complaining about the federal judges who put ideology before the welfare of the citizenry.

The one thing that the article blames is computing centers for AI. Those who are expecting to ultimately make money on AI should be the ones paying for the increased demand.

Much of the UK mainstream media seem unable to get over the fact that Trump won the election.

One example. The BBC late evening news banged on and on about Trump’s links to Epstein for well over a week showing the same film night after night. It was then announced that the Clinton’s links to him were being investigated which they did broadcast once but only once. Then they dropped any mention of Epstein altogether.

I wonder how many of these authors–and commenters–have mapped Permo-Triassic rocks so actually know what they show about conditions at that time. I have; in our part of the world they’re the Cache Creek Group and Takla Volcanics.

Hiking mountains and swamps with mosquito saturation is difficult work though; sitting in offices modelling at a computer is a lot easier way to form conclusions and make predictions.

Reportedly, there were signs of stress in some species about 1m years before the Permian-Triassic extinction event*. I think we should wait until there are signs of stress (eg. when NASA report a decline in leaf area), and then we would have a few hundred thousand years in which to work out a solution.

*Some think it all happened at 3pm on a Wednesday afternoon, but the evidence shows it was a bit slower than that, ie, about a million years (Tuesday to Tuesday).

Recent evidence suggests that the End Permian Extinction was less related to CO2 or increasing temperatures than it was to the release of toxic gases. Apparently, magmatic sills were emplaced under organic-rich sediments (either actual coal beds or proto-coal beds), driving off volatiles colloquially known as coal tars (as in benzene), carbon monoxide, and sulfur dioxide from included pyrite/marcasite. The sulfur dioxide, when dissolved in water, creates a strong acid — sulfuric acid — probably actually capable of significantly lowering the pH of all waters.

Populations cycle naturally, each in it’s own characteristic fashion, and extinction is “in the numbers” and inevitable. No special changes in the environment are required … The numbers get a little more complex when inter-species relationships are considered and impossibly complex when Gaia as a whole is involved..ie- the great extinction events are the “perfect storm” of additive cycles, and as pointed out above, take place over 10s & 100s of thousands of years– plenty of time for species to adapt, so it ain’t the changing environment. It’s just in the numbers. Cf- any textbook on Mathematical Biology

From my notes: Satellite imagery recently revealed a 300-mile wide impact crater in the Wilkes Land region of East Antarctica.  This asteroid impact was more than twice as large as the Chicxulub crater that caused extinction of the dinosaurs 185 million years later.  
The Wilkes Land asteroid is estimated to have been 30 miles in diameter.  Translational waves from the Antarctic impact propagated around the globe and focused at the anti-impact site, inducing an outbreak of volcanism over what is now called Siberia.  This impact event 250 million ybp is known as the “Great Dying,” the Permian-Triassic extinction event.  90% of all life on earth was obliterated.

August 19, 2025 10:25 pm

processes intrinsic to the Earth itself take over, acting as positive feedback to release dramatically more carbon into the system.

Pure, unadulterated speculation, with no basis in evidence, logic or reality. It’s the only leg they’ve got left to stand on, and it’s a very shakey one at best.

And it wouldn’t matter if CO2 were higher or lower than it is today, or whether the Earth was warmer or cooler as a result. It’s the rate of change in CO2 that gets you to Armageddon.

Ah, the old, “rate of change” hand-woven from full on dyed-in-the-wool BS. We don’t have anything like the resolution in proxies to determine what rates of change occurred in the past. It’s a ludicrous pretension.

Strangely, intelligent, educated people seem to swallow all this bunk without giving it any proper examination or rational thought. It’s quite sad.

The PT transition is just more than elevated levels of CO2 and water vapour, it is the enormous volumes of tephra being thrown up into the air by intense and prolonged exhalative volcanic activity. These eruptive sequences are primarily rhyolitic bringing with it enormous releases of a toxic plume that include CO2 but also abundant SO2 and just about everything else.
And the source is correct; this went on for at least 2 million years.
With tuffaceous sequences (grey) interbedded with the coals (black) being reported in the Bulli Seams in the Sydney Basin it is likely that volcanic activity was a fact of life well into the Triassic from the Mid Permian as seen in the type outcrop.
There is no comparison with today’s paltry efforts. Rest easy
