The Arctic is getting wetter. Higher temperatures→more evaporation from oceans→higher atmospheric humidity→total precipitation (snow+rain) is increasing. Snowfall would be increasing were it not for warming that crosses the 0°C threshold more often. Thus, the Arctic

🚨Paper Alert! A new paper, co-authored by VAW Matthias Huss, shows glaciers worldwide have lost over 9,000 Gt of ice since 1976, raising sea levels by ~25 mm. 🌍 The paper presents a global dataset of annual glacier mass change from 1976–2024. Explore: 📊 doi.org/10.5194/essd-1…
