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!
When a government speaks responsibly about climate risks. Iceland's climate minister: "We believe that confronting climate tipping points and the risks they pose openly is not a sign of 'pessimism' or 'alarmism' but a sign of realism and responsibility." youtu.be/B-0eQnEEsYA?si…

After COP30 Fire and Floods: AMOC Shutdown
This has to be said. No credible scientist thinks the planet is heading into an ice age. Here’s the real story. Global warming and melting Greenland Ice threatens collapsing the vital Atlantic circulation called the AMOC (timetable uncertain, but there’s some chance it starts…
Hey Murdoch fake-news media! The study you report on here 1. Predicts nothing but is about the past. 2. Is not about Gulf Stream but #AMOC. 3. An AMOC collapse wouldn’t cause an Ice Age. Incompetence or intent? The study by Ren shows AMOC has weakened: nature.com/articles/s4324…
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.

Der Tagessspiegel über meine gestrige Rede in Berlin: tagesspiegel.de/berlin/klimafo… 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: pik-potsdam.de/~stefan/FFFDem…
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. theguardian.com/environment/20…
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…
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! table.media/berlin/news/me…
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. table.media/berlin/news/me…
