When and why the “Doomsday Glacier” started melting. As of: February 28, 2024, 11:51 a.m By: Nico Reiter CommentsPressSplit The Thwaites Glacier has been in retreat for decades.

A new study is now said to have found the start time and trigger of the significant melting. The researchers describe that the changes were triggered by an El Niño warm phase. The decline was therefore triggered by changes in sea and air circulation and not by internal or local events.
