Antarctica’s ‘Doomsday Glacier’ could meet its doom within 3 years

Time is melting away for one of Antarctica‘s biggest glaciers, and its rapid deterioration could end with the ice shelf’s complete collapse in just a few years, researchers warned at a virtual press briefing on Monday (Dec. 13) at the annual meeting of the American Geophysical Union (AGU). 

Thwaites glacier in western Antarctica is the widest glacier on Earth, spanning about 80 miles (120 kilometers) and extending to a depth of about 2,600 to 3,900 feet (800 to 1,200 meters) at its grounding line — where the glacier transitions from a land-attached ice mass to a floating ice shelf in the Amundsen Sea. Thwaites is sometimes referred to as the “Doomsday Glacier,” as its collapse could trigger a cascade of glacial collapse in Antarctica, and the latest research from the frozen continent suggests that doomsday may be coming for the dwindling glacier even sooner than expected.
