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!
High resolution images from satellite and from eddy-resolving ocean circulation models point to an ongoing decline of the Atlantic overturning circulation, a key ocean current for our climate. Read more about it in my new blog article. 🌊 realclimate.org/index.php/arch…
IEA: Renewables have cut fossil-fuel imports for more than 100 countries | @Josh_Gabbatiss @IEA Read here: buff.ly/moV7Tge

The numbers of electric vehicles sold in Europe in 2024 are in: ⚡ 1.45 million new battery-only EVs registered 📈 +32% growth in the total electric fleet 🔋 13.6% of all new car registrations are electric Europe is going full throttle to a clean future.…

If the likelihood of a catastrophic event is > 10% then the Risks are unacceptable high. This is the point we have reached on scientific evidence for AMOC shutdown. This is the "Don't look up moment" for risks of liveability on Earth theguardian.com/environment/20…
Rainfall intensity is increasing because the atmosphere holds more moisture as the planet heats. These kind of scenes will occur in completely unexpected places.

🌍 For the FIRST TIME on record, renewables generated more electricity than coal in H1-2025. Renewables rose 363 TWh (+8%) to supply 34.2% of global power, while coal’s share fell to 33.1%. ember-energy.org/latest-insight…

Great interview of climate scientist Mike Mann and virologist Peter Hotez on the war on science by special interest groups. My colleague Mann endured vicious attacks after his pioneering (and solidly confirmed) ‘hockey stick’ curve of #globalwarming. pbs.org/newshour/show/…
Top right is how far “off the charts” September 2025 sea surface temps are in this area of the North Pacific. >1.6C or ~3F above normal on average over this huge area. I’d say even more alarming than the actual anomaly is the trend since 2010. In 15 years the anomaly jumped more…

The North Pacific heatwave these past few months has been astonishing. Take a look at the bottom of this image. It’s “accumulated heat stress” from NOAA’s Coral Reef Watch program. Basically the whole north basin registers Alert Level 5, dark purple. The dark purple also happens…

Dr. Jane Goodall filmed an interview in March 2025 with the understanding it would only be released after her death. This is her final message from it.
Oh my. Notice how these catastrophic flood videos are now happening daily? Surely it’s never “just” climate change and these floods have occurred before. But a warmer climate does make them more frequent and fierce.
The resort town of Elenite, Bulgaria over the last 48 hours. A heating atmosphere holds more moisture which means rainfall intensity is increasing across the planet. Watch David Attenborough’s breaking boundaries on Netflix. We are in a planetary emergency.
“Bivalve records are like the tree rings of the sea. They offer a continuous, annually resolved record of ocean conditions.” New study finds #AMOC destabilization since 1950 "suggesting that the region is moving toward a tipping point."🌊 insideclimatenews.org/news/03102025/…
Excellent, well-informed new podcast! Like a ship entering a storm, we’re now entering the overshoot - a world above 1.5 degrees C #globalwarming. This requires a whole new mindset, explored by Laurie Laybourn.
Episode 1: Uncharted Territory If the world didn’t win, has it lost? We meet the underdog diplomats who helped the world set the 1.5°C goal, and the champion sailors who can help us set a course for navigating what comes next. Listen to episode one now: open.spotify.com/episode/1bJl5i…
Win-win: mehr Lebensfreude vor Ort, weniger Klimagase in der Welt! Ein Traum, den Berlin Vorbildern wie Paris, Amsterdam, Kopenhagen & Barcelona nachmachen sollte.
So sollten Städte in der Realität aussehen! 😍🌳🚲 @jan_kamensky präsentiert seine Arbeit beim #ADFCSymposium. Mehr auf: visualutopias.com
Was die einen als “grüne Experimente” diffamieren können die Menschen in vielen anderen Städten längst als Lebensqualität genießen: Kopenhagen, Amsterdam, Wien, Barcelona, Paris, Utrecht, … Weniger Emissionen & weniger Stau für alle, die dann noch Auto fahren.
Kopenhagen: lebendige, lebenswerte Stadt, weil alle Verkehrsteilnehmer ausgewogen Platz erhalten - nicht nur Autofahrer. Davon profitieren alle. Manche Politiker in 🇩🇪 gruseln sich anscheinend vor solchen Verhältnissen...
