Beach holidays in the climate crisis, France. As an old viral quote said: “Climate change will manifest as a series of disasters viewed through phones with footage that gets closer and closer to where you live until you’re the one filming it.”

Yesterday afternoon 14:09 in Lacanau Océan in France. A pale red sun through the smoke tinged everything in Mars style orange. Welcome in the climate emergency! Despite all denial of the fossil fuel lobby, it’s scientific fact: CO2 emissions heat up Earth & make fires worse. 🔥🔥🔥
Holiday in the climate emergency. No that’s not AI or edited, just a snapshot I just took with my phone on Lacanau beach in France. What future will this boy grow up in? It is in our hands, but time is running out.

Important new study out at Nature Climate Action showing that individual climate actions do not stop people from participating in collective climate action. Instead, they were associated with greater collective engagement and somewhat stronger policy support. www.nature.com/articles/s44...

Fires in France have now burned over 91,000 acres, by far the most of any year since the satellite record started in 2006. Current area burned is about 34x larger than this date in a typical (median) year:

“The climate scientists we surveyed were unambiguous: current economic models can’t capture what matters most – the cascading failures and compounding shocks that define climate risk in a warmer world – and could undermine the very foundations of economic growth.” Should be the top story everyday.

Turning on the ‘For You’ algorithm on X may shift users’ political opinions towards more conservative views, reports a paper in Nature. These effects are shown to persist even after users return to a chronological feed. 🧪
The political effects of X’s feed algorithm - Nature
Among users initially on a chronological feed, 7 weeks of exposure to X’s algorithmic feed in 2023 shifted political attitudes and account-following behaviour in a more conservative direction compared with those remaining on a chronological feed, whereas switching the feed setting in the opposite direction, from algorithmic to chronological, had no effect.
