Modeling the Future of the Greenland Ice Sheet

The video discusses the potential future of the Greenland ice sheet, which may disappear within a millennium due to climate change. Andy Ashwant, a glaciologist, explains how NASA data is used to model possible futures of the ice sheet. The model considers different emission scenarios, with the current trajectory being the highest emission path. This could lead to significant sea level rise. The video emphasizes the importance of understanding these dynamics to inform future decisions.
