One of the most ominous risks for Europe is that of a major change in Atlantic ocean currents. Recent science suggests it has been greatly underestimated in the past -including by me, having worked on it for over 30 years. Here my half-hour presentation in Vilnius a week ago!

Iceland now considers this a national security threat. https://t.co/fckxDy5eqy And the Foreign Intelligence Service of Germany together with other German institutions published a National Climate Risk Assessment this year. Here is what it says about #AMOC tipping risk.

Is the Atlantic Ocean circulation close to tipping? 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. https://t.co/jyJ2xf2qjC

In 2024, renewable energy accounted for over 90% of global power capacity expansion. That is because it makes economic sense. IRENA_DAT_RE_Capacity_Highlights_2025-1.pdf

All nations committed under the Paris Agreement to limit global warming to 1.5 degC for good reason. Instead many governments are beholden to the fossil fuel lobby and even subsidize fossil fuel use with your money. We’re now at 1.4 degC & emissions are rising not falling.

“If we wait to cross tipping points before we act, it will be too late. The only credible risk management strategy is to act in advance.” https://t.co/7bCaGLPPqS

#COP30 Don't miss this important event tonight with PIK Director @jrockstrom, Carlos Nobre, Mary Robinson and more: "Justice and Wellbeing within Planetary Boundaries: Pathways for COP30". 18:30 Side Event Room 2 (Blue Zone). Find out more: https://t.co/n1TAgv2g45

Have you checked how flood-proof your house is? You can’t rely on past experience in a changing climate.

Der Tagessspiegel über meine gestrige Rede in Berlin: https://t.co/oFW2f4jXEx Die 45 Grad beziehen sich natürlich auf extreme Hitze: heute bis 39 Grad, künftig durchaus bis 45 Grad. Mein Redetext (pdf) mit Links zu den fachlichen Quellen der Aussagen:

Even limiting global warming to 1.6–1.8C would require far stronger policies to reduce fossil fuel emissions than those currently adopted by governments, which would allow the world to heat by at least 2.7°C, says PIK Director @jrockstrom at #COP30.

@jdamijan @rahmstorf The statements are broadly supported by paleoclimate proxies and observations: Holocene temperatures were relatively stable compared to glacial cycles, but current warming rates exceed those over the past 2,000 years. Many weather extremes, like record heatwaves, surpass

30 years COP - do your job! Climate protest in Berlin

Ist jeder Mensch in der Bundesregierung sich dieser immensen Verantwortung bewusst? Frage für meine Kinder.

In Sonntagsreden angeblich hinter dem Pariser Klimaabkommen stehen, aber dann die Abrissbirne am Klimaschutz ansetzen? Heute könnt ihr zeigen, was ihr davon haltet, in Berlin und vielen weiteren Orten. Die Mehrheit der Menschen will mehr Klimaschutz! https://t.co/DELBSVa8sX

Scientific sources to check yourself: Holocene: https://t.co/tL1StIpfzj Extremes: https://t.co/B4Ac8DBpyX Sea level: https://t.co/hLmDUjiH7y Tipping points:

Never forget: At breakneck speed we are leaving the stable Holocene climate in which human society developed and thrived. Weather extremes are outside historical experience. Sea-level rise is accelerating. Dangerous tipping points are ahead. Graph: https://t.co/UNaqGEKMQc

Das wird immer wieder weltweit bestätigt, hier aktuell bei uns in 🇩🇪: die Mehrheit der Menschen wünscht sich mehr Klimaschutz! Denn wir haben die Lösungen, aber wir verlieren gerade den Wettlauf gegen die Zeit für eine lebenswerte Zukunft. https://t.co/DELBSVa8sX

“Wir in Deutschland importieren fossile Brennstoffe für mehr als 80 Milliarden Euro pro Jahr. Das ist buchstäblich verbranntes Geld. … Sogar in Deutschland verkaufen sich Wärmepumpen, aller Desinformation zum Trotz, längst besser als Gasheizungen.” https://t.co/06ujz5VoaA

Sometimes I want to cry when I see all the denial and then look at this. But I do understand it. It’s hard to face because it really is deeply, deeply frightening. #climateCrisis

Taifune sind - genau wie Hurrikane - tropische Wirbelstürme (sie heißen nur im Pazifik anders). Sie bekommen durch die globale Erwärmung immer mehr Zerstörungskraft.
