The Thwaites Glacier in West Antarctica — nicknamed the “Doomsday Glacier” because its collapse could cause catastrophic sea level rise — is the world’s widest glacier and roughly the size of Florida.
Thwaites, which already contributes 4% to global sea level rise, holds enough ice to raise sea levels by more than 2 feet.
“This process of widespread, enormous seawater intrusion will increase the projections of sea level rise from Antarctica,” he added.
Sea ice around Rothera Point, on Adelaide Island to the west of the Antarctic Peninsula.
The researchers also used climate models to predict the potential speed of recovery from such extreme sea ice loss and found that even after two decades, not all the ice will return.
