Every year, the world's glaciers lose 266 billion tonnes of ice. This Saturday marks #WorldGlaciersDay — a reminder of what's at stake. Understanding how glaciers and ice sheets move, thin, and lose mass is essential for projecting future sea level rise. @ESA's Climate Change Initiative Glaciers and Ice Sheets projects deliver the long-term satellite records to do just that. Both Greenland and Antarctica are losing ice: 🌍 Glaciers worldwide: − 266 Gt/yr 🟢 Greenland ice sheet: − 166 Gt/yr, driven by rising air temperatures and surface melting 🔵 Antarctica ice sheet: − 111 Gt/yr, driven by ocean warming and increased glacier flow Find out more about the projects and access the data via the links in the comments.

📡 Predicting droughts that cause severe food insecurity in the Eastern Horn of Africa is possible – with months-long lead times. The science is improving to become a bigger part of the climate strategy in the region to increase resilience. 👉 ow.ly/k7g150UOxG9

Scaling Conservation Agriculture can help shift food production back within Planetary Boundaries. It now spans ~200M ha globally and could reach 50% of cropland by 2050. Healthy soils are key to food security & Earth system stability. New article out now👇 cambridge.org/core/journals/…

Snow cover is one of Earth's most sensitive climate indicators, yet a consistent long-term daily record has been missing, until now.❄️ @ESA's Climate Change Initiative Snow project developed a 45-year global daily snow cover record, spanning from 1979 to 2023. Researchers from @unibern harmonised data from 16 satellite sensors into a single, gap-filled dataset. With high temporal and regional detail, it captures the complexity of snow cover changes in a way that was previously not possible. The dataset supports climate modelling, water resource management, and permafrost research – making it a valuable tool for better understanding Earth's climate system.

MaLeFix.. Spoiler alert: we won’t choose such a difficult title again.. But what does it mean?

What exists up to 11,000 meters below the surface? And why should we care? It’s the deep seabed - one of Earth’s last great frontiers - and full of mysterious life. 🦑🪸 Here are 5 things you need to know - and how to protect it 👇

Waldbrände im Klimawandel: Ist die Schweiz vorbereitet? 🔥🌲 Lange galt die Schweiz als Land mit geringem Waldbrandrisiko. Doch vermehrt und länger andauernde Trockenperioden, weniger Schnee sowie die veränderte Landnutzung erhöhen das Waldbrandrisiko. dora.lib4ri.ch/wsl/islandora/…

Trees are "biological machines." 🌳 Data shows: - 1 tree = cooling power of 10 AC units - Trees lower surface temps by up to 12°C - Urban forests help slash energy bills & urban heat island effect Time to move trees from the "Landscaping" budget to "Infrastructure"?

💧🔥🌲Ein Frühwarnsystem gegen Dürren. MaLeFiX hat ein Frühwarnsystem für Dürren in der Schweiz entwickelt, das verschiedene Umweltbereiche berücksichtigt. Dadurch sind Vorhersagen mit einer Vorlaufzeit von bis zu 32 Tagen möglich. drought.ch/de/impakt-vorh…
