The massive "doomsday glacier" known for its rapid destabilization is undergoing a "vigorous ice melt" that scientists say could reshape sea level rise projections. In a new study, glaciologists from the University of California, Irvine, found that warm, high-pressure ocean water is seeping beneath West Antarctica's Thwaites Glacier, making it more vulnerable to melting than previously thought. The glacier is roughly 80 miles across, the widest on Earth. It packs so much ice that if it were to completely collapse, it could singlehandedly cause global sea levels to rise by more than two feet, according to the International Thwaites Glacier...

Ocean water is pushing miles beneath Antarctica’s “Doomsday Glacier,” making it more vulnerable to melting than previously thought, according to new research which used radar data from space to perform an X-ray of the crucial glacier. As the salty, relatively warm ocean water meets the ice, it’s causing “vigorous melting” underneath the glacier and could mean global sea level rise projections are being underestimated, according to the study published Monday in the Proceedings of the National Academy of Sciences. The Thwaites Glacier in West Antarctica — nicknamed the “Doomsday Glacier” because its collapse could cause catastrophic sea level rise —...
