Since the 1990s, glaciers around the world have been losing ice faster than they can recover, and the pace is only accelerating. In 2024, glaciers in Scandinavia, Svalbard, and North Asia recorded their largest annual mass loss ever observed. 🔗 https://bit.ly/4ivRNPc

🏔️ Glaciers lost 450 gigatons of water in 2024. This is enough to form a block of ice 7 km tall, 7 km wide, and 7 km deep or to fill 180 million Olympic swimming pools. Help us amplify #Glaciers2025: we need urgent climate action now. 🔗 https://bit.ly/4ivRNPc
