Antarctica's 'Doomsday Glacier' Could Double Sea Level Rise Predictions

A new computer model suggests that Antarctica's Thwaites Glacier, often referred to as the 'Doomsday Glacier,' could contribute twice as much to global sea level rise as previously estimated, even without additional global warming. Researchers found that warm ocean water is penetrating miles beneath the ice, weakening its foundations and accelerating its retreat, potentially adding up to 30 millimeters to global sea levels by 2100.
