8/ This is the heart of why we go. To share the wonder, to inspire, and to show that science belongs to everyone. 🌍❄️

7/ 👉 Teachers, parents, curious minds: sign up now & be part of the journey. Link here: 8e999342.sibforms.com/serve/MUIFAH...

6/ None of this would be possible without our partners:
@unesco.org
, Fondation Etrillard, Fondation Alphonse Weicker. 🙏

5/ But this program is not just about receiving content. It’s about exchange.
💬 Schools will send us questions directly.
🎥 We’ll host live calls from Antarctica.
🐧 Paco the penguin will guide the youngest explorers!

4/ 📚 Every week (from Nov 12), a digital workbook will land in inboxes worldwide — stories, games & activities linking geography, history, climate & biodiversity to our mission.

3/ That’s why, with Temoins Polaires, we’re launching the ❄️ Under Antarctica Educational Program ❄️. For 3 months, children, teachers & families will follow us for free as we kite-ski across the ice.

2/ One of the main reasons
Matthieu Tordeur and I are undertaking this enormous expedition is not just for science, but to open its doors to young people everywhere. To spark curiosity & rebuild trust in science.

1/ ❄️ Antarctica is calling — and we want to bring the next generation with us.

Bonjour,

Avec 60 scientifiques de 54 institutions et 17 pays, nous avons réactualisé le suivi des indicateurs clés du changement climatique et de l'influence humaine jusqu'à fin 2024,

Graph showing monthly-mean Arctic mean near-surface air temperatures for 2025 using a red line. There is a strong seasonal cycle, with a peak during the boreal summer season. There is a long-term warming trend. The other years from 1940 to 2024 are shown with sequential coloring for blue to white. Data is from ECMWF ERA5 reanalysis. The graphic is updated through April 2025.

My collection of monthly #Arctic temperature graphics have just been updated through April 2025: zacklabe.com/arctic-tempe...

thanks so much Bethan!!

Quel devrait être le scénario de montée du niveau de la mer pour guider l'adaptation du littoral 🇫🇷 de manière cohérente avec la trajectoire de référence pour l'adaptation au changement climatique anticipant 3°C de réchauffement mondial soit 4°C en France d'ici 2100 ?

Please do join us if you are interested James!! Would be so nice to have you :))

Global map showing surface air temperature anomalies for the December 2024 to February 2025 period. Most all areas are warmer than average, except for La Nina. Anomalies are calculated in reference to a 1951-1980 climate baseline using GISTEMPv4.

Now looking at a spatial view of temperature anomalies during the December to February 2025 period again highlights the relative Arctic warmth and lack of cold departures to be found anywhere outside of the central Pacific.

We seek to highlight the people dedicated to the study, exploration and preservation of the cryosphere while inspiring the need for in its preservation.

The Cryosphere Pavilion aims to celebrate the International Year of Glaciers Preservation 2025 and the Decade of Action for Cryospheric Sciences.

We are thrilled to announce that the Cryosphere Pavilion side event application process for UN Ocean Conference in Nice is now open!

The Pavilion funded by the Fondation Albédo pour la Cryosphère is on a mission to bring the cryosphere’s message to the world.

Rain in the northernmost city on Earth. This month temperatures have been almost always above normal.

The Arctic is becoming totally unrecognisable.

And in the meantime #BP and #Equinor are doubling down on fossil fuels.

Profits over people. Profits over a liveable Earth.

Now, we’re bringing this adventure to you through a 13-minute film—a deep dive into the heart of the Greenland Ice Sheet, where exploration, science, and sustainability meet.

🎥 A film by imagerie-films.fr, produced by Airbus Solutions and 90 degrees south.

Satellite imagery from @AirbusSpace was our guide, helping us navigate shifting ice, crevasses, and supraglacial lakes. 🛰️🔍

With eyes in the sky, we adapted our route to Greenland’s dynamic and ever-changing landscape. 🚀

🎬 Greenland, 1500 km by kite-ski in the name of science: THE MOVIE! 🎥

Last summer, Matthieu Tordeur and I traversed 1500 km of the Greenland Ice Sheet, powered by the wind. Our mission? To test kiting for scientific research and document climate change in the Arctic. 🌍❄️

It was another stunning year for global climate and weather extremes.

As data is processed and released in the first two weeks of January, you are going to be hearing all about these new historical records. Apologies for my many graphs in advance! 😬
