Do you think climate science needs to be better communicated? We do too! That's why we are looking for a climate science communication specialist to join the Technical Support Unit of the IPCC Working Group I. All details can be found here: www.ipcc.ch/2025/09/17/c... Please share!

🚨 📢 #LesActusIPSL "Accélération des bouleversements en Antarctique : une convergence de signaux alarmants" tinyurl.com/ye7eynjv Jean-Baptiste Sallée #LOCEAN_IPSL @cnrs.fr I @sorbonne-universite.fr I @ird-fr.bsky.social I @mnhn.fr

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...

If you want to get your simple climate model picked up by IPCC AR7, see below 👇 We have 11 on our radar from the previous round of RCMIP (egusphere.copernicus.org/preprints/20...), plus a few others we found since. Anybody we don't know about please ping me or Alex

New starter pack with @ipcc.bsky.social #AR7 scientists (bureau, authors, REs)! Full list: apps.ipcc.ch/report/autho... For SR cities scientists see separate starter pack! @dianaurge.bsky.social @sherilee.bsky.social @siir-kilkis.bsky.social @janfuglestvedt.bsky.social go.bsky.app/2FuXb3Y

Have you been selected as an Author for the IPCC AR7 and are you planning to attend the Ocean Sciences Meeting 2026? Please get in touch! I am convening an IPCC-focused Town Hall and will invite a panel of Authors to address the scientific challenges for AR7 and answer questions from the community

The list of selected authors for the IPCC AR7 is now public 🌍 apps.ipcc.ch/report/autho... It is an honour to have recently joined the Technical Support Unit of the IPCC Working Group I as Science Coordinator. Looking forward to authors coming onboard and the report to come to life!

The Nazis burned books, attacked universities, and crippled German science. The MAGAs delete websites, attack universities, and cripple American science. The website www.globalchange.gov of the mandated Global Change Research Program & all the National Climate Assessment reports has been deleted.

There’s so much happening right now, I thought I’d put together a running thread on the dismantling of #climate and research and knowledge infrastructure in the United States 🧵

La période de maccarthysme s'ouvre donc officiellement par un article d'un journal national historique, qui dresse une liste d'intellectuels "woke". L'état de déliquescence morale et politique de ce pays est effrayant... www.lefigaro.fr/actualite-fr...

#EGU25 🌊 Come have a chat now and before 4pm at X4.37, I have cookies! 🗣Additionally I now have a last-minute talk at 17:43 today in room 1.34 in the same session

In the train to Vienna for #EGU25, first international conference since maternity leave! I will present: 1. AERA-MIP results on emission pathways and budgets compatible with 1.5 and 2C global warming —> Tuesday at 14:05 in CL4.13 (TCRE/ZEC session) meetingorganizer.copernicus.org/EGU25/EGU25-...

Atmospheric CO2 has passed 430 parts per million. The last time atmospheric CO2 was at 430 ppm was during the ancient Pliocene Era, three to five million years ago, and humans didn’t exist.

🚨 Climate experts wanted! The new U.S. Academic Alliance for the #IPCC (@ipcc.bsky.social), hosted by #AGU, is accepting nominations for the Seventh Assessment Report. 📅 Deadline: April 4 🌍 Apply now: www.agu.org/ipcc-nominat... Join a global effort to advance #climatescience & action!

Bonjour, Connaissez-vous le réseau de profileurs Argo? C'est une clé de voûte de l'observation de l'océan. www.argo-france.fr/Argo-France/... 1/...

📢 Postdoc Opportunity: Ocean Tipping Points & Impacts! We're hiring a postdoc in my group at the University of Bern, Switzerland, to study ocean tipping points and their impacts. The position is part of HEurope project TipESM (@tipesm.bsky.social). Feel free to reach out with any questions. 🌊

‪In solidarity with scientists and academics working in the United States, Argentina, and all countries where academic freedom is under threat. Today, French scientists and citizens rally in more that 30 cities #StandUpForScience @standupforscience.bsky.social @cdelawalla.bsky.social

🌍🌡️Les politiques #Climat visant la #NeutralitéCarbone sont des politiques de #SantéPublique. ⚕️💰Leurs bénéfices peuvent même contrebalancer les coûts de leur mise en œuvre. 📜🧪 c’est ce que nous montrons dans une étude publiée aujourd’hui dans Lancet Planetary Health doi.org/10.1016/S254... 🧵 1/

🌍🌡️ #Climate policies aiming at #NetZeroEMission are genuily #PublicHealth policies ⚕️💰 Their benefits may even outweigh their implementation costs. 📜🧪 That’s what we found in a study published today in The Lancet Planetary Health : doi.org/10.1016/S254... 🧵 1/

I run a yearlong program called Life Skills for Young Scientists where we study essential skills for a happy and meaningful life. Each month I record a talk about a relevant topic. These might be useful resources: open.spotify.com/show/7GQcLJG... This month: "Staying Motivated in Difficult Times"

🎙️ I'm happy to present at the next GO2NE webinar on 21 January! I'll be sharing our recently published research showing that the effects of wind and buoyancy forcing on global #ocean #deoxygenation have partially offset each other since the 1960s. 🌎🌊

🚨Paper alert: The adaptive emission reduction approach was used to simulate 1.5°C & 2°C temperature stabilization in 13 Earth system models. Key findings: remaining carbon budgets 60% larger than in IPCC AR6, budgets evolve over time, pos. emissions under stabilized warming doi.org/10.5194/esd-...

Has the Atlantic Meridional Overturning Circulation (AMOC) weakened over the last decades? In our new study, we combine state-of-the-art CMIP6 models and observation-based estimates of the air-sea heat flux in the North Atlantic to show that the AMOC has not declined since the 1960s! 🌊
