The study, published Monday in the Natural science to find The Thwaites Glacier is known as the “doomsday glacier” because it holds enough water to lift global sea level by several feet, is particularly vulnerable to ocean warming caused by climate change because it lies on the sea floor and can therefore be melted from below. After extensive mapping of the ocean floor, the researchers found that at some point in the last 200 years, the base of the glacier moved off the sea floor and retreated at twice the rate of recent retreat.

If Thwaites makes another such rapid retreat, the results could be “existential,” said University of South Florida marine geologist Alastair Graham, a co-author of the study. Washington Post.
The specter of the rapid disintegration of the Thwaites Glacier arises as Greenland — which lost enough ice in one weekend this summer to put West Virginia under water — recorded the largest September ice melt on record. “This [September] The event demonstrates how global warming is increasing not only the intensity but also the duration of the melting season,” said Maurice van Tiggelen, a polar scientist at Utrecht University in the Netherlands.
