‘Doomsday Glacier’ is teetering even closer to disaster than scientists thought, new seafloor map shows

Underwater robots that peered underneath Antarctica’s Thwaites Glacier, nicknamed the “Doomsday Glacier,” noticed that its doom could come prior to anticipated with an excessive spike in ice loss. An in depth map of the seafloor surrounding the icy behemoth has revealed that the glacier underwent durations of fast retreat inside the previous couple of centuries, which could possibly be triggered once more by means of soften pushed by climate change. 

Thwaites Glacier is a large chunk of ice — across the identical dimension because the state of Florida within the U.S. or the whole thing of the UK — that’s slowly melting into the ocean off West Antarctica (opens in new tab). The glacier will get its ominous nickname due to the “spine-chilling” implications of its total liquidation, which might elevate world sea ranges between 3 and 10 ft (0.9 and three meters), researchers said in a statement (opens in new tab). Attributable to local weather change, the large frozen mass is retreating twice as quick because it was 30 years in the past and is dropping round 50 billion tons (45 billion metric tons) of ice yearly, in accordance with the International Thwaites Glacier Collaboration (opens in new tab).
