NASA: West Antarctica Ice melting fast. 1.2 to 3 Meter rise of water expected

A key area of ice in west Antarctica may already be unstable enough to cause global sea levels to rise by 3m, scientists said on Monday.

The study follows research published last year, led by Nasa glaciologist Eric Rignot, warning that ice in the Antarctic had gone into a state of irreversible retreat, that the melting was considered “unstoppable” and could raise sea level by 1.2m.

This time, researchers at Germany’s Potsdam Institute for Climate Impact Research pointed to the long-term impacts of the crucial Amundsen Sea sector of west Antarctica, which they said “has most likely been destabilised.”
