State of the Greenland Ice Sheet

NASA scientists have been studying Greenland's ice for over a decade, using satellites and lasers to measure changes. They found that 100 billion tons of ice melt annually. The Peterman Glacier, a major ice chunk, has doubled its speed in five years, contributing significant freshwater to the ocean. This is part of a global trend, with 99% of Alaska's and 87% of Antarctica's glaciers retreating. The melting ice affects climate regulation, sea levels, and habitats, posing catastrophic risks if it continues.
