Greenland’s fast-melting ice sheet will cause a huge sea level rise with potentially ominous implications over this century as temperatures continue to rise, according to a study published on Monday.
Melting “zombie” ice from the enormous Greenland ice sheet will eventually raise the global sea level by at least 27 centimetres (10 inches) just on its own. “Zombie”, or doomed ice is still attached to thicker areas of the sheet but is no longer getting fed by larger glaciers.
The study in the journal Nature Climate Change said sea rise could reach as much as 78cm (30 inches) – enough to swamp vast swathes of low-lying coastlines and supercharge floods and storm surges.
This should serve “as an ominous prognosis for Greenland’s trajectory through a 21st century of warming”, the authors said.
By contrast, last year’s Intergovernmental Panel on Climate Change (IPCC) report projected a range of 6-13cm (2-5 inches) for likely sea level rise from Greenland ice melt by …
