West Antarctic ice collapse may be prevented by snowing ocean water onto it

eurekalert.org – The ice sheet covering West Antarctica is at risk of sliding off into the ocean. While further ice-sheet destabilisation in other parts of the continent may be limited by a reduction of greenhouse gas emissions, the slow, yet inexorable loss of West Antarctic ice is likely to continue even after climate warming is stabilised. A collapse might take hundreds of years but will raise sea levels worldwide by more than three meters.
