🚨 Important paper in Nature: "Systematic attribution of heatwaves to the emissions of carbon majors". www.nature.com/articles/s41...

Hot off the press: We can provide for the first time a systematic attribution of recent #heatwaves to the emissions of #carbon_majors. Essential new #Nature article coordinated by @yannquilcaille.bsky.social at @ethz.ch, with numerous contributors @usyseth.bsky.social: www.nature.com/articles/s41...

𝗕𝗶𝗴 𝗻𝗲𝘄𝘀: 𝗺𝘆 𝗳𝗶𝗿𝘀𝘁 𝗣𝗵𝗗 𝗽𝗮𝗽𝗲𝗿 𝗶𝘀 𝗼𝘂𝘁! We looked at how climate change is already affecting run-of-river hydropower in Switzerland—and what that means for electricity system planning. 📄 Published in Environmental Research Letters. 🔗 Link to the paper: 10.1088/1748-9326/ade4df

I’m at EGU in Vienna this week, and will be presenting my current project tomorrow morning around 9, pass by if you’re interested or want to connect! Link to the abstract here: meetingorganizer.copernicus.org/EGU25/EGU25-...

Everyday I read about a new enraging Trump decision, but I don’t see much retaliation yet from those affected and those that oppose his fascist policies. Is there really no large-scale mobilization in the USA against Trump?

Let’s call it what it is: a witch-hunt, and the victims are scientists and all those working for a better future.

Avec l'actualité c'est un peu passé inaperçu, mais plus de 10 ans après la mort de Rémi Fraisse, la Cour Européenne des Droits de l'Homme vient de condamner la France pour violation du droit à la vie.

Excellente liste d’actions pour aller de l’avant et faire la différence, minime soit elle, dans un monde qui sombre de plus en plus dans l’autoritarisme et la violence politique!

There is no automatic reversion to "normal" in politics. Nor will the timid business-as-usual which got us into this mess get us out of it. We'll achieve a better society after Trump and similar tyrants only through massive and focused movement-building. It has to start right now.

I think the crazy developments in the US ought to remind us to hold our representatives accountable, to inform ourselves through credible sources and to engage with those that don’t share our opinions. It’s fundamental to counter populist takes based on misinformation, to not end up like the US🙃

Incoming comment from Trump asking where is the global warming everybody talks about🫠

The best climate solutions -- by far -- are the ones that are ready to scale *now*. Waiting for pie-in-the-sky tech solutions, which never seem to show up as promised, is *exactly* the wrong thing to do.

Pour une fois, je suis d’accord avec Yaël Braun-Pivet. Cette invisibilisation de la catastrophe à Mayotte montre de nouveau le peu d’intérêt qu’accorde les politiques pour les catastrophes climatiques (encore plus quand elles surviennent en outre mer)

I was just watching the recording of the Deep Learning for Climate and Weather session @agu.org, and I could not believe the level of condescendence of some of the speakers (see screenshot). AI/ML research needs more humility and respect, we should be working hand in hand, not one against the other.

I get that COPs are the best we have but they are infuriating - it is so hard to simply keep past commitments let alone accelerate action at the speed and scale required to have any hope of achieving the goals of the Paris Agreement. Shame on the countries that show up to obstruct rather than act.

Brilliant thread summarizing each country’s interventions during the #COP29 Plenary. Not surprised to read that most countries express disappointment in this year’s COP. Very weak developments, anchored in a logic of delay.

Softening the definition of Net Zero won’t stop global warming. As authors of the 2009 “Net Zero Papers” we call on countries and companies to recognise the need for Geological Net Zero, balancing flows of carbon into and out of the Earth’s crust. www.theguardian.com/environment/...

We wrote a student-led open letter to Mukhtar Babayev COP29 President urging COP29 to commit to drastic emission cuts, and reached more than 700 signatories now! Please sign this letter and spread it further cop29letter.org #COP29 #ClimateAction

I really understand why Bluesky is viewed as the version of Twitter that people enjoyed, hope it stays like that🙏🏼

A gentle reminder that if we miss the 1.5°C target (and we certainly will), the next target is 1.51°C and not 2°C. We need to keep fighting. Every tonne of CO₂ emitted makes the job of future CO₂ removal harder, and every 0.01°C of temperature increase makes the world more chaotic and dangerous.
