✨ Huge thanks to all instructors & participants for making the ELLIS Winter School on AI for Earth System, Hazards & Climate Extremes so engaging and interactive!
👏 Special thanks to OroraTech, ESA Academy & ICEYE — your support enabled 10 participants to join, helping make the school more diverse.
Final day at the ELLIS Winter School on “AI for Earth System, Hazards & Climate Extremes.” 🎉
Group challenge presentations, keynote reflections and well-deserved awards marked the conclusion of an intense week of collaboration and learning.
Thanks to everyone who made it happen!
Day 4 of the ELLIS Winter School on “AI for Earth System, Hazards & Climate Extremes” kept the momentum going. 🔬
Challenge teams refined their solutions, supported by expert insights and keynote talks on AI for climate and Earth systems and stakeholder engagement.

We’re in Athens for the ELLIS Winter School 2026 🌍
This week, researchers and students are coming together to explore how AI can help understand and respond to climate extremes, from floods and wildfires to droughts.
Hands-on learning in action. ✋
Momentum continued on day four of the ELLIS Winter School 🚀
From Zero2Hero sessions to lively challenge sessions, participants sharpened their skills and exchanged ideas across disciplines.
Evening at the National Observatory of Athens — no stargazing due to clouds, but a great tour instead 🌥️🔭
This kind of collaboration is what truly makes the difference! Bringing together different projects and perspectives adds so much depth and diversity to the school — and creates a richer experience for everyone involved. 🌍
🇬🇷 Day 2 of the ELLIS Winter School took us to Lavrion Campus for keynotes on AI for Earth at scale, foundation models, and ocean extremes — plus a great career panel highlighting the diverse and often non-linear paths into climate & AI.
Science + sea air + career insights 🌊
Day 1 of the ELLIS Winter School in Athens 🇬🇷
Keynotes on early warning of climate risks and a planetary data layer for an observable Earth, plus a powerful talk from Zisoula Ntasiou (Hellenic Fire Service) on how science and AI can support firefighters making decisions in the field.
👋We are ready.
The venue is set, the slides are polished, and we can’t wait to welcome you to the ELLIS Winter School on “AI for Earth System, Hazards & Climate Extremes.”
Let’s build, learn, and collaborate!

🌍 Can we predict atmospheric CO₂ growth?
Using 6 Earth System prediction systems with an interactive carbon cycle, we show:
• CO₂ growth and air-land CO₂ fluxes predictable up to 2 yrs
• Air–sea CO₂ fluxes up to 5 yrs
A step toward carbon-cycle early warning.

💡 New Paper!
Deep learning can predict runoff — but uncertainty matters.
This study shows that engression + LSTM delivers:
✅ Better uncertainty estimates
✅ Realistic time-series simulations
✅ Stronger performance
for trustworthy environmental forecasts.
