Hear the latest science as I presented it last month at the ATLAS25 event in Helsinki.
Let me know if anything is unclear, or if you see good reasons why your government shouldn't immediately act on this. 🌊

Using a 1880-1920 pre-industrial reference baseline (as preferred by @drjamesehansen.bsky.social et al.), 2025 will be close to +1.5°C.
That's with the tropical Pacific causing some relative cooling (La Niña)!

It's not exponential (like the @clubofrome.org 1972 'Limit's to growth' projection), but there is little indication of the growth rate stabilizing (let alone decreasing) any time soon either.

Code UFB!!!
The three-year running mean for the global surface temperature anomaly now exceeds 1.50°C over the pre-industrial baseline, as of November 8, 2025.
Are you there, COP 30? It's me, the Paris Agreement.

"If a warm snap melts enough Arctic ice fast enough, the stage will be set for the collapse of the North Atlantic Current ... As things now stand, this situation is inevitable. It is going to happen, and nobody knows when."

It's looking like 2025 may end up with the second lowest global sea-ice maximum since records began in 1988, behind only 2024. And 2016 is just barely higher.
Stay tuned!

Emissions are still going through the roof, there is backtracking on green measures, and a just transition is as far away as ever

Global Sea Surface Temperatures are likely even higher than the Eemian warm period, 125,000 years ago, when global sea levels were 5-10 meters higher than today.
October 2025 Sea Surface Temperatures still being above pre-2023 records is another indication of higher climate sensitivity👇

Will we see a new record low soon? The Climate 8-ball has been pocketed.

Global 2-meter temperatures once again broke the Paris limit on Sept. 14 and Sept. 15, reaching 1.52°C above the 1850-1900 IPCC baseline both days, marking the 2nd hottest temperatures for the date on record, and possibly in the last 120,000 years.

We didn't quite follow the exponential increase in atmospheric CO₂, but got close!
We've already completely altered the global climate.

By itself, 'Taxing Billionaires' is just siphoning the money from the hyper-rich to the government. Bad idea. (1/3)

2024 PITR: +1.6C (El Nino)
=
+2C in 2035. Just 10 years, folks
+2.5C by 2040? This rate IS accelerating.
If I told you you had LESS than 10 years to save the world, would you do what it takes?

The planet's albedo (reflectivity) hit yet another new record low as of the latest data from CERES from April, 2025, now at 28.714%.

It's the 31st heatwave since 1901.
15 of which occurred since 2000.
Implying an increase of ~300%!
And there were only 8 heatwaves during the first 75 years of the 20th century.
