🇪🇺 Last Saturday, ECMWF joined #Europatag in Bonn. It was a great opportunity to connect with visitors and share more about ECMWF’s work, including contributions to EU initiatives such as Copernicus and Destination Earth. Thank you to everyone who stopped by the ECMWF stand throughout the day.

This week, ECMWF staff attended #EGU2026 in Vienna, which brought together geoscientists from all over the world. Our staff contributed to over 25 sessions on topics ranging from AI for weather forecasting to flood prediction and hydrological modelling. More information ➡️ lnkd.in/d6AYyytr

"The truth is: the natural world is changing. And we are totally dependent on that world... It is the most precious thing we have, and we need to defend it." Happy 100th birthday to Sir David Attenborough, whose stories transformed how we view and understand our Earth.

@rebeccalize.bsky.social, Senior Scientist @ecmwf.int, Lead Editor of #ESOTC2025, shares her perspective on the report. She reflects on the finding that surprised her most, the result that deserves closer attention & how the report can help everyone make sense of Europe’s changing climate. More ⬇️

❄️In 2025, much of Europe saw fewer snow days than average, while end‑of‑season snow cover extent was 31% below average and snow mass 45% below, both the 3rd lowest in 42 years. 🔗 More info climate.copernicus.eu/esotc/2025/s... @ecmwf.int & @wmo-global.bsky.social #CopernicusClimate
