The headline from 27 August 2024 at SciTechDaily reads Earth’s Temperature Could Increase by 25 Degrees: Startling New Research Reveals That CO2 Has More Impact Than Previously Thought.
I’m not surprised by this catastrophic new paper; I have been expecting to see ‘step changes’ in the climate system and the multiplicative consequences of the six dozen feedback loops that Professor Guy McPherson has identified. As Professor Peter Wadhams pointed out to Guy, the feedback loops are multiplicative, not ‘only’ additive!

In 2017 I wrote an article based on an analysis by David Wasdell that concluded that 10C was “baked in”, the article is titled “Full Earth System Sensitivity to CO2 has been Grossly Underestimated.”
In May 2019, I woke up to find that Professor Peter Wadhams, possibly the most experienced scientist in the world when it comes to Arctic Sea Ice, had posted the following response to the blog post:
“The analysis of climate sensitivity by David Wasdell is very important. I have been through it with him several times and am convinced of its validity. I mentioned it in “A Farewell to Ice”. The point is that here is a big difference between the short term sensitivity, which is used to calculate warming over a few years, and the long term sensitivity which represents how much warming the earth is going to be subjected to if you don’t add more CO2 but let the effects of the present levels work their way fully through the climate system. Short term sensitivity is 2-4.5 C, but long term is more like 10C. The crime of IPCC and other modelling outfits is that they are aware of this difference between short and long term, but still use the short term value even when they are doing hand-waving studies of what is going to happen over the next century or two. In fact it’s not just the case that the magic 1.5C or 2C warming is already “baked in” to the global system – in fact the baked in figure is more like 4-5 C. Hence the vital need for carbon drawdown. Best wishes Peter Wadhams”
Now with new analysis, we find that 14C is baked in!
The analysis above comes from a post from my dear friend and colleague Professor Guy McPhersons’ Substack account titled: “Science Snippets: Earth’s Temperature Could Increase by 14 C”

I’ll finish with a quote from the late great Albert Bartlett: “The Greatest Shortcoming of the Human Race is our inability to truly understand the exponential Function.”
He too has been proven correct.
How quickly will this unravel?
The great unravelling is clearly underway. My personal view is that we are now a day-to-day proposition.
We’ve hurtled off the cliff after decades of ‘Kicking the can down the road”, now that we’ve driven the ecosystem off the cliff, this entire shitshow could unravel between when you go to sleep and when you wake up!
I was in Berlin one week before the “Berlin Wall” came tumbling down. There had been demonstrations in Leipzig that week but there was no hint that the GDR would completely collapse, but it did. Soon after the USSR collapsed.
Our weakest link is “Complexity”, I’ve previously considered that aspect of collapse in my blog post: The Myth of Human Progress and the Collapse of Complex Societies. Chris Hedges & Joseph Tainter.
Another pathway to collapse is financial contagion in the banking system.
There’s a great lecture from David Korowicz published on June 17, 2012 embedded following: Financial system supply-chain cross contagion – a study in global systemic collapse
Good luck everyone, we sure are going to need it, soon we’ll all be walking around looking as stunned as the people in Valencia Spain after the latest deluges in Europe!
Thanks, Kevin.
Good to hear from you.
Breathing deeply and treasuring every day.

Thanks, Kevin, for all you do, especially posting these articles.
Especially enjoyed the video of Albert Bartlett as he dished out plenty of valid and little-known statistics, interspersed with clips of fake news by Forbes’ CEO, and others.
As a side note, it is said that in recent times, often tourists will visit the Miami area just to observe the flooding in streets and store-front businesses, when it isn’t even storm related. Apparently it’s just a fact of life for some Floridians now.
Thanks again.

“Such short-term variables are smoothed out in the black linear trend that shows a steady rise of about 0.5°C over the three years from end 2022 to end 2025”
Half a degree C rise in three years!
Nothing screams runaway more than that.
Feedback loops are clearly at play, there is no denying it!
MECHANISMS BEHIND A STEEP RISE IN TEMPERATURE
“The first image shows the temperature rise from end 2022 through February 22, 2025, with trends added. The shading in the above image reflects the presence of El Niño conditions (pink shading) that push up temperatures, La Niña conditions (blue shading) that suppress temperatures, or neutral conditions (gray shading). Such short-term variables are smoothed out in the black linear trend that shows a steady rise of about 0.5°C over the three years from end 2022 to end 2025.”
