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!

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:

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

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
yonasilvy.bsky.social
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.

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 🧵

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.

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/...
Argo est un programme international qui coordonne la collecte des informations à l'intérieur de l'océan à l'aide d'une flotte d'instruments robotisés. Ces instruments, les flotteurs profileurs, dérivent avec les courants océaniques et se déplacent à la verticale entre la surface et 2000m, 4000m ou le fond des océans. Les données recueillies par Argo décrivent la température et la salinité de l'eau et certains flotteurs mesurent d'autres propriétés qui décrivent la biologie/chimie de l'océan. 

Le réseau de flotteurs travaille en partenariat avec les satellites d'observation de la Terre, Jason, qui mesurent la forme de la surface de l'océan.

Chaque profileur Argo est mis à l'eau depuis un navire.  Une fois dans l’eau, le flotteur descend pour se stabiliser vers 1km de profondeur. Dix jours plus tard, le flotteur descend jusqu'à 2, 4 ou 6km de profondeur, puis remonte à la surface. Lors de son ascension vers la surface, les capteurs embarqués s’activent et mesurent les propriétés de l'océan. Arrivé en surface, le flotteur transmet, via des satellites, les données et sa position à des stations de réception à terre. Le flotteur coule ensuite à nouveau pour répéter le cycle de 10 jours jusqu'à ce que ses batteries soient épuisées.
