Faster than estimated retreat of glaciers on the East Antarctic Ice Sheet

Feature article in Nature, Vol. 544, Issue 7649, 13 April 2017, pp. 152-154, “The threat beneath Antarctica”

 

Summary of article: Although the retreat of glaciers on the West Antarctic Ice Sheet is commonly thought to be faster than those on the larger East Antarctic Ice Sheet, new observations have showed that Totten glacier on East Antarctic Ice Sheet is melting and retreating faster than expected from the grounding line where the glacier meets the increasingly warming Southern Ocean. This observation raises new questions concerning the long held notion that the East Antarctic Ice Sheet is more stable than its counterpart in the west of the continent. Possible complete melting of the East Antarctic Ice Sheet could raise sea levels by as much as 50 metres.
