The expansion of knowledge has unfolded alongside the expansion of harm. The damage is neither unforeseen nor poorly understood; it is documented in real time. What impedes response is not ignorance, but the gravitational pull of convenience, entrenched power, and habitual patterns of consumption.

Vol. 1, no.4 of the CO2 Newsletter, first published in April 1980 (that's not a typo) is now downloadable. Founded by American geologist William Barbat, each was 8 pages of excerpts from recent reports, editorials and deeply researched articles.

"What impedes response is not ignorance, but the gravitational pull of convenience, entrenched power, and habitual patterns of consumption and governance. We continue, knowingly, to accelerate processes whose consequences we can quantify with unsettling accuracy."

Thanks for the kind feedback.

i appreciate the work Kevin has done here

well worth a read

it’s grim but bracing

"The Arithmetic Of Climate Failure". my response to a series of questions posed by Alma Asfalto & published last week.

3️⃣ Professor @kevinclimate.bsky.social at the National Emergency Briefing:

UK must cut emissions far faster than planned even to limit warming to 2°C.

And that's before accounting for mounting evidence that heating has accelerated.

Point of no return: a hellish ‘hothouse Earth’ getting closer, scientists say Continued global heating could set irreversible course by triggering climate tipping points, but most people unaware

Crossing climate tipping points "would lock the world into a new and hellish 'hothouse Earth' climate far worse than the 2-3C temperature rise the world is on track to reach."

Probably fine.

+2C by 2030s?! YouTube video by Climate Chat

We could reach +2°C of global warming next decade!

Graphic shows three line graph time series of monthly carbon dioxide abundance in ppm (blue line), monthly methane abundance in ppb (red line), and monthly nitrous oxide in ppb (purple line). Graphs are all shown from January 1984 through January 2026/October 2025. Current levels of CO2 are 429 ppm. Current levels of methane are 1946 ppb. Current levels of nitrous oxide are 339 ppb. All graphs show long-term increasing trends along with some interannual variability and seasonality.

Greenhouse gas concentrations keep rising. The planet keeps warming in response. And that added heat shows up in the extremes and impacts. This is really basic stuff.

The presentation builds on and expands my short contribution to last November’s National Emergency Briefing. climateuncensored.com/national-eme...

Duration: 50-minute talk followed by a 30-minute Q&A.

A wonderful talk. IMO, the best of the maybe 10 I saw over the years, better than the NEbriefing one too, wrt slides and performance/act. Seeing WG2 highlighted had me💃!!
Lots to talk about with others.
But let me tell you wrt equity & CO2budget: non-dev'ed countries do not need the same pc CO2.

@kevinclimate.bsky.social leading the way really now with communicating just what dite straits we're in

“no non-radical pathways now remain. We face a stark choice: rapid and far-reaching social and technical change, or a delayed transition marked by increasingly chaotic, and potentially violent, social disruption as climate impacts accelerate.“

I consider this to be a must-watch for everyone, everywhere. @kevinclimate.bsky.social doesn't sugar-coat the situation we're in, he tells it straight.
We need to understand the deep trouble we're in.

Wonderful talk. The best of the maybe 10 I saw over the years. Some slides are made for beginners. Emotion and ethics r pointed out. Attention pulled to experts in lying, eg 🇨🇦Carney and the now-IPCC chair Skea.
And calls for self-empowerment: push for progress within your radius so it can spread🕸️💪

Many thanks for the very kind comment and the thread; really appreciated.

"Fostering moral disengagement facilitates & encourages unrestrained, excessive consumption. …demand for air travel has been driven by the ideological manufacture of desire through targeted airline promotions that seek to ‘create’ consumers and accelerate air travel consumption."

Regulation needed.

Journal of Sustainable tourism. 2026, Vol. 34, no. 2, 296–312 On all fronts: how to end aviation exceptionalism James Maclaurin, Elisabeth Ellis and James Higham ABSTRACT We argue thataviation xceptionalism is both a demand side and a supply side problem.Despite exponentialincreases in demand for international air travel, plane makers have achieved only modest linear movement toward low carbon aviation technologies. Meanwhile, the global aviation regime has become adept at shaping user practices and culture to enable and encourage unconstrained air travel consumption.This has influenced the public’s perception of possible regulatory regimes and, along with persistent overestimation of technical debt, has prevented the use of regulations similar to those that are successfully moving the automotive sector to new low-carbon technologies. On the supply side, there is no realistic prospect of attaining sustainable aviation technology without a government-led, private-sector supported, moonshot-style collective effort. On the demand side, the psychological barriers to behavior change will not be resolved without confronting the drivers that ‘create’ air travel consumption and artificially accelerate demand. Introduction We have long known about the potentially catastrophic consequences of climate change (IPCC 2022). We have also known, in broad terms, what we need to do to avert disaster (Stern & Stiglitz, 2023). All successful solutions involve some mix of social/behavioral change, regulation, scientific discovery & commercialization of technological innovations (Geels & Kemp, 2007). Results have been mixed. 30 years after COP1 in Berlin there are still domains in which none of these strategies has had a significant effect on carbon emissions and radiative forcing more generally. This paper takes international aviation as an example of such an intractable domain… Reasons given for exceptions… no longer justify the exceptional status of international aviation…

The "global aviation regime [is] adept at shaping user practices & culture to enable & encourage unconstrained air travel… This has influenced the public’s perception of possible regulatory regimes…"

"confront…artificial[] acceleration [of] demand."

This link climateuncensored.com/national-eme... takes you to the video recording of my 15-min' presentation at the National Emergency Briefing @nebriefing.bsky.social & a 10-min' interview I gave to wedonthavetime.org immediately after the event (Nov. 2025). Selected slides attached for reference.

Thanks for the feedback - & certainly an insightful quote.

Thanks for the kind comment.

Thanks for the kind support.

The carbon opportunity cost of animal-sourced food production on land - Nature Sustainability Shifting global food production to plant-based diets by 2050 can sequester 99–163% of the CO2 emissions budget towards limiting climate warming to 1.5 °C.

Ach ja. I tend to snort hopium, sorry. You're right of course.
And these 700Gt CO2 bound in rewilded areas currently in use for animal agri are also not safely stored in the new/old biomes. If climate keeps changing bc we keep emitting, they can go up in flames-eq too.

Hi Stephen. That’s certainly fine by me. I look forward to catching up.

You already can look it here. And it's really worth it.

Not sure - I'll enquire.
