If you want to know more about how we established that there is a statistically significant increase in the speed of global warming since 2015, @CarbonBrief explains it nicely.

Unsere neue Studie: die Erderwärmung hat sich ab 2015 erheblich beschleunigt. Die rote Kurve zeigt 10-Jahres-Trends, um je 1 Jahr versetzt; der letzte ist 2015-2024. Die blaue Kurve zeigt den Trend vor und nach dem objektiv bestimmten change point. 👉 https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2025GL118804

R to @rahmstorf: The paper: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2025GL118804

R to @rahmstorf: Re the quoted comment by a colleague that one might be fooled by natural variations such as hot years due to El Niño events: that is exactly why in 2011 we developed our method to remove such natural variations due to El Niño, volcanism 🌋 & solar ☀️activity, which we used here.

The Guardian on our new study, which shows that global heating is significantly gathering speed. Our efforts to overcome our fossil fuel addiction should do the same. https://www.theguardian.com/environment/2026/mar/06/humanity-heating-planet-faster-than-ever-before-study-finds

"If pandemic threat assessment and preparedness was as fragmented, we would be scandalised." It was great talking to Ellen for this excellent piece in Prospect Magazine about climate risk and the threat of AMOC collapse specifically Essential reading! https://www.prospectmagazine.co.uk/world/environment-news/climate/72586/is-a-deep-freeze-coming

“You have a lot of people here for whom the risk of extreme flooding is much higher than people thought’' - Anders Levermann comments on a new study showing that baseline calculations for coastal water levels have been underestimated. https://apnews.com/article/sea-level-rise-climate-change-flooding-warming-59bb59d2fe839224a10bd28d604b5d95

"Wir dürfen unser Naturkapital nicht verschleudern", so PIK-Direktor #Edenhofer im @rbb24. Er spricht über Veränderungen in der globalen Klimapolitik, das Verhältnis von Wissenschaft und Politik & aktuelle Herausforderungen im europäischen Emissionshandel. https://www.inforadio.de/rubriken/vis-a-vis/2026/03/ottmar-edenhofer-co-direktor-potsdam-institu-fuer-klimafolgenforschung.html

Kolumne: Die Welt verändert sich in atemberaubendem Tempo. Sie wird heißer, schneller, fossile Geschäftsmodelle sterben zwangsläufig, neue entstehen. Die Bundesregierung setzt stattdessen auf Retro-Technik. Das ist schlecht für das Land - und schlecht für die Menschheit.

Was im Heizungskeller drin ist, ist Privatsache. Was oben aus dem Schornstein kommt selbstverständlich nicht. Es verursacht zunehmend Schäden und gefährdet Gesundheit und Leben, und ist deshalb verbindlich im Pariser Abkommen, in der EU und im 🇩🇪 Klimaschutzgesetz geregelt.

Zur Erinnerung: Klimaschutz schützt die Freiheit! CO2-Emissionen gefährden zunehmend Leben und Gesundheit. Bundesverfassungsgericht, Urteil vom 24. März 2021.

Around 6,000 ocean scientists are meeting in Glasgow at the AGU Ocean Sciences Meeting, discussing how fossil-fuel-caused climate change is affecting sea levels, ocean currents and life in our oceans. #OSM26

Erstaunlich, dies seit Jahrzehnten immer wieder erklären zu müssen. Weniger erstaunlich, dass Klimatäuscher für ihre Zwecke dann sogar ein 5 Jahre altes Video hervorholen - ehrliche Argumente haben sie schon lange nicht mehr.

Quite an eye-opening video about the tech bros by the inimitable ClimateAdam. Watch it. https://youtu.be/py0XpKxAnNU

On #PolarVortex instability science and the increase of Arctic cold air outbreaks, I posted a thread a while ago which was from Twitter as it was from 2021. I just remembered there is actually this version of it outside X, so here it is: https://threadreaderapp.com/thread/1362058117593366535.html

What do tipping points mean for climate policy? Climate change won't be smooth. Delay reaching emission targets by a few years, and you might not just get slightly worse climate impacts. You may unwittingly cross a line for unstoppable, massive changes. https://global-tipping-points.org/

Great Channel 4 News report on the latest #AMOC monitoring. "Trouble is: there is now growing scientific consensus that the AMOC is weakening." https://youtu.be/JpOpsMOBsL4?si=ICb5J5vEyvSnFRH5

Stürme, Überschwemmungen und Hitze werden mit zunehmender Erderhitzung häufiger und heftiger. Während die globale Durchschnittstemperatur seit Beginn der Industrialisierung um etwa 1,4 Grad gestiegen ist, ist Europa ungefähr 2,4 Grad heißer geworden. https://www.taz.de/!6154994

Wir werden immer abhängiger von amerikanischem Gas. Die politische Entwicklung in den USA spricht nicht für diese Abhängigkeit. Wir sollten das tun, was China erfolgreich macht: massiver Ausbau der Erneuerbaren um unabhängig zu werden. https://x.com/janrosenow/status/2022658346403451206?s=46&t=KTVNieBywr9tCk5vjs2B-w

Nicht nur wir Bürger, auch die Politiker müssen die geltenden Gesetze einhalten. Zu den Errungenschaften des demokratischen Rechtsstaats gehört es, dass dies notfalls auch vor Gericht eingeklagt werden kann. Leider beim Klimaschutz immer wieder nötig. https://perspective-daily.de/article/4152-dieses-urteil-ist-ein-sieg-fuer-den-deutschen-klimaschutz/e0pXBvBf?pk_campaign=link-user

The transition to cleaner forms of energy are not happening fast enough to avoid dangerous climate change Read the full story: https://go.nature.com/4axLAjU

Wir befinden uns in einem dramatischen Wettlauf gegen die Zeit, die schlimmsten Klimafolgen (Verlust von vielen Küstenstädten, Hungersnöte, Konflikte, Kipppunkte etc.) noch abzuwenden, und die Politik macht… Bislang hat die Wissenschaft die Klimaerwärmung korrekt vorhergesagt.

Atmospheric scientist here. Let me tell you what was actually "slashed" today. Slashed: The Endangerment Finding — a 200-page scientific review upheld by the Supreme Court, the D.C. Circuit Court of Appeals, and reaffirmed by the National Academies of Sciences in 2025. Slashed: The legal authority to regulate carbon from cars, power plants, and factories. All of it. Gone in one afternoon. Now here's what you're "saving": Yesterday Trump ordered the Pentagon — the largest energy consumer on Earth — to buy coal electricity. Coal costs $69–$169/MWh. Wind costs $27–$53/MWh. Solar costs $38–$78/MWh. 99% of U.S. coal plants cost more to run than replacing them with brand-new solar or wind. That's your tax dollars buying the most expensive electricity on the market. By executive order. While the Peabody Energy CEO stood in the room. And the human cost of what you're "saving"? 460,000 American deaths linked to coal pollution in 20 years. Coal PM2.5 is 2.1x deadlier than other air pollution. (Henneman et al., Science, 2023) All to protect an industry that employs 44,000 people total. Clean energy employs 3.5 million.

The American Geophysical Union unequivocally condemns this reckless and senseless decision. AGU is a global community supporting more than half a million advocates and professionals in the Earth and space sciences. https://fromtheprow.agu.org/agu-denounces-trump-administrations-repeal-of-the-epa-endangerment-finding/

🤯🤯🤯 Full-on denial of reality. State capture by the fossil fuel lobby. The US descends into a banana republic. It would almost be funny if the consequences wouldn’t be so dire for billions of humans, if the courts don’t stop this folly soon.

Uncertainty is not your friend: In a new paper published in One Earth, scientists argue that uncertainties in climate projections mean Earth system components could be at a higher risk than we think of reaching crucial tipping points. 🌊 https://eos.org/articles/earths-climate-may-go-from-greenhouse-to-hothouse

"In October, the government classified the AMOC collapse as a national security risk. It amounts to a reckoning with national survival." And a major #AMOC change would seriously impact the world at large, even the tropics - not just Iceland. 🌊 https://www.adn.com/nation-world/2026/02/10/how-a-warming-planet-could-turn-iceland-into-a-glacier/

After thousands of stories, this is the last piece I'll ever write in the @washingtonpost. It's about Iceland, looking at the planet's future, seeing an existential threat. https://wapo.st/4rFJRQs

Average winter temperatures have increased: weather station data prove it. And the incidence of cold air outbreaks from the polar vortex has increased: objective cluster analyses of weather patterns shows it. Both results are peer-reviewed & falsifiable. https://x.com/rahmstorf/status/1362058117593366535?s=46&t=DyZDJL9gznjLS_bux96mTw

Devastating floods have hit Portugal & Spain in past days, causing loss of life & billions of Euros in damages. How does climate change impact the flood risks from rain, rivers & rising seas? Watch my lecture Flooded Futures: What are We Planning For? 🌊 https://www.youtube.com/watch?v=wtd8ZFWIFMA

“Here we have a serious problem: America is addicted to oil.” — President George W. Bush, State of the Union, January 31, 2006

Kernenergie - egal ob Fusion oder Spaltung - hat zudem das Problem der Abwärme, genau wie fossile Energie. Noch ist es klein verglichen mit CO2, aber bei weiter wachsendem Energiebedarf der Menschheit wird das bald ein relevantes Erwärmungsproblem. https://x.com/rahmstorf/status/1603448183333568516

Nuclear (fusion or fission) is not a main solution to our long-term energy supply because of the inescapable waste heat problem, not because of any fuel shortage.
