Hey Cryoverse! 👋
If you need any motivation to call for action on the #AmbitionForMeltingIce at #COP30, check out the Glacier Casualty List. It's a global summary of 'critically endangered' & 'disappeared' glaciers and their stories.
It's really happening. 🧊💧

The Semper Crevasses project is keeping us busy on the ice sheet this week! Here's the view into one of Greenland's newest crevasses, which has opened in recent months at 2000 m elevation above sea-level about 100 km inland from Ilulissat Glacier front.

This particular figure places recent ice-sheet projections in the context of paleo sea-level changes.
