A major ice shelf in Antarctica appears to have survived a period of hot temperatures more than 120,000 years ago, indicating that the West Antarctic ice sheet may not be as vulnerable as we ...

indicating that the West Antarctic ice sheet may not be as vulnerable as we thought to complete collapse caused by climate change – a worst-case situation that could raise sea levels by metres.

The West Antarctic Ice Sheet holds enough ice to raise sea levels by 13 to 16.4 feet, with areas like the Thwaites Glacier at risk due to warming waters. An international team, including Molly ...

“Our reassessment of West Antarctica's contribution to sea level rise if the ice sheet was to collapse is about 3.3 metres,” he said. “That is about half of the value that has been quoted up ...

Parts of the Antarctic ice sheet are thought to have collapsed in the past, most recently during the Last Interglacial period (between 130 000 and 115 000 years before present) and may well do so ...

They do worry, however, that the West Antarctic Ice Sheet might shrink enough to raise global sea levels appreciably in the coming centuries. The worst-case scenario is a complete collapse of the ...

Current estimates indicate a near-total collapse of the West Antarctic Ice Sheet by the year 2300, giving humanity approximately 275 years to mitigate its deterioration amid increasing volcanic ...

Genomic evidence for West Antarctic Ice Sheet collapse during the Last Interglacial by Lau, S.C., et al is published in Science December 2023.

A new study analyzes the possibility of such a collapse by creating models surrounding four of these pillars: the West Antarctic Ice Sheet, the Greenland Ice Sheet, and Amazon Rainforest ...
