Doomsday Glacier 2024. For the first time, visible evidence has been captured showing warm seawater pumping beneath antarctica’s thwaites glacier, known as the doomsday glacier. Scientists are warning of dramatic changes at one of the biggest glaciers in antarctica, potentially within the next five to 10 years.

Ocean tides are burrowing beneath a thick sheet of antarctic ice—dubbed the “doomsday glacier” for its threat to global sea levels—and melting it from below. At 80 miles across, thwaites is the world’s widest glacier.
