The Israeli Government has made an ad about the Global Sumud Flotilla headed for Gaza, and it's surprsingly honest and informative.

L'été 2025 a été marqué par les évènements climatiques extrêmes. Mais riches et pauvres sont-ils exposés de la même manière ? Réponse en 5 minutes avec @mikmeh.bsky.social qui a soutenu une thèse sur ce sujet au @cired.bsky.social. www.radiofrance.fr/francecultur...

Amorcer la déchéance de nationalité d'un citoyen américain uniquement car... c'est un opposant de gauche qui a des chances d'être élu maire de New-York. Voici l'intention explicite de l'administration Trump. Sans exagération aucune : Chaque jour qui passe, la démocratie s'estompe aux Etats-Unis.

Our paper has just been published in Nature Cities ! ✨👇

Imagine, just imagine, the response from the West if the Iranian government, in international waters, had rammed and then boarded a European ship, filled with European citizens, and taken them captive. But it's Israel, so it's all good. Our citizens don't matter.

Colonial extraction and unequal exchange have shaped two centuries of North-South inequality. A thread on the new study written with @gatonievas.bsky.social [A thread 1/8🧵]

En France, la pollution aux particules fines augmente l'absentéisme des salariés, baisse leur productivité, affecte les consommateurs et nuit in fine aux entreprises. J'explique les résultats de notre étude menée avec Hélène Ollivier au micro de @vgarin.bsky.social pour RTL: shorturl.at/nbubg

Who's responsible for the climate crisis? Two new studies try to answer this question: but whichever way we slice it, the answer doesn't change much. The wealthiest are disproportionately responsible for the greatest emissions, and that's why climate change is so unfair. An explanatory thread 🧵

🔴New paper! Next month, the #FfD4 UN conference will try to find resources to finance sustainable development, in the context of plummeting foreign aid. Meanwhile, I show that extreme poverty cannot be eradicated by 2030 (SDG1) without international transfers. www.tandfonline.com/doi/abs/10.1...

"Bonobos [one of our closest relatives] refuse to participate when faced with unequal rewards." The vast majority of people similarly want fairness between us, but almost always end up with leaders who don't. That mismatch is the single biggest barrier to a better world. phys.org/news/2025-04...

This piece from @jvl.bsky.social is one of the most important insightful I have read since January 20th 2025.

In 25 years of covering national security, I’ve never seen a story like this: Senior Trump officials discussed planning for the U.S. attack on Yemen in a Signal group--and inadvertently added the editor-in-chief of The Atlantic. www.theatlantic.com/politics/arc...

From a source: “Just had a co-presenter for a buildings research conference bow out. She’s a dual citizen and the FBI came knocking to ask her about her involvement in coauthoring chunks of the Paris Agreement. Climate science is being literally (and I mean literally) criminalized.”

‘Elle est passée où ta Greta Thunberg ?’ 
Elle est toujours là, active, à se battre pour le climat. C’est juste qu’elle est aussi contre la colonisation et les gouvernements d’extrême-droite donc quand elle a communiqué sur le genocide en Palestine de nombreux médias ont cessé de parler d’elle.

Notre première étude Agoratlas ! Où on a trouvé des milliers de bots/trolls insultants Zelensky, et félicitant Trump. La première partie de l'étude étant dans le lien cité, je vais profiter de mon thread perso pour vous parler de ma journée et du process derrière 😅

"Dans n’importe quel autre pays, un milliardaire comme Musk installant des loyalistes pour s’emparer des agences fédérales, accéder aux données privées des citoyens et aux informations sur ses concurrents (...), serait qualifié de coup d’État." www.democracynow.org/2025/2/3/elo...

I'm thrilled to announce that my latest research, "High-Resolution Downscaling of Disposable Income in Europe Using Open-Source Data," has been published in Earth's Future. 🌍📊 @agu.org

To my Canadian and Mexican friends hit by the absurd Trump tariffs, I say: do this! You can fight back by hitting the US oligarchy 👇👇👇 www.theguardian.com/commentisfre...

Trump put a freeze on hiring air traffic controllers and, on Musk’s instruction, fired the FAA chief early without replacing him. This should be the only thing Dems are saying today. They should all be out on media saying this.

Very sad news. Linda Mearns was a remarkable person, an enthusiastic and wise climate scientist, with a deep sense of service to society. She has an exceptional legacy in advancing rigorous methods to distillate actionable regional information - and shaping @ipcc.bsky.social reports.

Should we ban new gas boilers to mitigate climate change? Célia Escribe and Lucas Vivier, my former colleagues at CIRED, have just published a great paper in which they model the energy system and the residential sector to address this question. @cired.bsky.social www.nature.com/articles/s41...

Looking for books to get for #climate curious friends & family this Christmas🎄? Here are 6 of my favourites reads this year. First up @doctorvive.bsky.social's indispensable guide to talking climate action & fighting fossil fuel propaganda 🧵

Tout comme les lobbys du tabac & industries fossiles, ceux des pesticides sont des criminels au regard du nombre de morts et de souffrance qu'ils entretiennent. Hier nous savions, ajd nous en savons encore davantage... Les politiques ne peuvent pas dire qu'ils ne savent pas. Ils sont complices. 1/2

Une transition climatique réussie nécessite des politiques qui n'entrent pas en conflit avec valeurs&sentiments des populations impliquées. L'incapacité à comprendre les résistances se traduit par réactions négatives et au final nourrit l'inaction 👇article 10insightsclimate.science/year-2024/br...
