Authoritarianism is undermining #climate action – and time is running out as warming accelerates and tipping points draw near. But as globalisation fades, national governments must assert their role in leading a climate emergency response: johnmenadue.com/post/2026/02… @johnmenadue.

Trigger warning/warming: “A major El Niño is under way, forecast to peak near +4.0 °C in Nov 2026” and “This year is on track for 1.63°C ±0.05°C above preindustrial.” dashboard.theclimatebrink.co… #Climate

I resigned from Anthropic today. I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives. More thoughts below.

Ominous news. Permafrost melting has accelerated since the turn of the century, a big study of 156 sites worldwide has shown. 90% of high mountain regions are affected. Rising temperatures are blamed and runaway climate change could ensue. phys.org/news/2026-08-permaf…

When Labor Cabinet signs off on new coal and gas, they should be shown this.
When someone denies climate change, show them this. #Nepal #Rasuwa

The El Nino is off the charts. Can people see the real issue and accept the implications? We may be getting closer. See the Bigger Problem – mailchi.mp/caa/super-duper-e… Also available on Substack: jimehansen.substack.com/p/su…

July 2026 was nominally the 2nd warmest July on record, with a global average of 1.56 ± 0.09 °C (2.80 ± 0.15 °F) above the 1850–1900 average — the first month of 2026 to exceed 1.5 °C — behind only July 2023 and effectively tied with July 2024. berkeleyearth.org/july-2026-…

With all August model runs now in (except for SINTEX-F), we now expect this year's El Niño event to peak sometime between October and December at a stunning 4C in the Niño3.4 region. To see all the latest numbers, check out the Climate Dashboard (link below)

Breaking: El Niño strength forecasts have just taken another step higher. The new ECMWF outlook shows the event peaking near +4.0˚C in December — obliterating the previous record. This will have sweeping implications on global climate patterns from late this year into 2027.

Marvelous examination of how to spot 2026-era AI writing, via the Economist - AI likes long sentences with less punctuation; “and” is its most overused word - relatedly, lists of three things, which drives up use of "and" as well - polysyllabic adjectives: “significant”, “increasingly” - scientific jargon ("rate-limiting," “parameter”) - nominalizations (making nouns from verbs: eg, “expansion” from “expand”) - ofc, everyone's favorite: "it's not X, it's Y"

Climate change made the huge Spanish wildfires at least 20 times more likely, scientists conclude. Just the latest study to have linked heatwaves and wildfires to global heating. Causes of ignition vary, but the underlying conditions are crucial. theguardian.com/world/2026/j…

CO₂ emissions are only part of the story. The critical question is how much warming they trigger. @djspratt explains climate sensitivity—and why understanding it is essential to understanding our future. #climatechange #climateaction #climatesensitivity #warming #MEER
