Why does the seafloor in the Gulf of Guinea vibrate at exactly 16 and 26 seconds? 🌊 A 60-year mystery now solved. The cause: ocean swells from Southern Ocean storms triggering resonance in fluid-filled cracks beneath the ocean floor. 📄 Poli et al. (2026) in Nature: www.nature.com/articles/s41...

European State of the Climate 2025 by @wmo-global.bsky.social & @copernicusecmwf.bsky.social is out: Record wildfires, highest-ever sea surface temperatures, glacier loss across Europe. ESA CCI data reveals 81% of European lakes were warmer than average in 2025. climate.copernicus.eu/esotc/2025?u...

Antarctica is gaining ice mass, but not because ice loss is slowing. 🧊 Iceberg calving is up ~100 gigatonnes per year, yet a snowfall surge is outpacing it – for now. ESA-funded research explains why. 👉 climate.esa.int/en/news-even...

Satellites provide the big picture of sea ice. Planes, moorings, ships, buoys and submarines validate these measurements. By comparing 30 years of data, researchers found strong agreement once spatial and temporal representativeness were considered. 👉 Full study: doi.org/10.5194/essd...

🔎 Track land cover changes over decades! The new Climate Change Initiative Toolbox Notebooks provide regional access to high-resolution land cover data from 1990 to 2019. They are perfect for studying deforestation and ecosystem transitions. Explore the Notebooks here: github.com/esa-cci/esa-...

🧊 A glacier in Tibet collapsed and nobody noticed for two years. Satellite data from the ESA Climate Change Initiative revealed what happened: the glacier tongue had vanished. Scientists reconstructed the entire event from space 🛰️ Worth a read: climate.esa.int/en/news-even...

Last chance to register! Our webinar on permafrost thaw is in 2 days. Annett Bartsch will show how satellites track permafrost thaw across Arctic lowlands & mountain regions, and what nearly 30 years of data reveal: where it’s accelerating and how unevenly. Secure your spot: tinyurl.com/k6mhk53z
