Sea level will be driven up no matter how much carbon emissions are cut, putting coastal cities in danger
Melting icebergs on Horseshoe island in west Antartica. The ice sheet of west Antarctica would push up the oceans by 5 metres if lost completely.Melting icebergs on Horseshoe island in west Antartica. The ice sheet of west Antarctica would push up the oceans by 5 metres if lost completely.is inevitable for the rest of the century no matter how much carbon emissions are cut, research indicates.
Losing the floating ice shelves means the glacial ice sheets on land are freed to slide more rapidly into the ocean. Many millions of people live in coastal cities that are vulnerable to sea level rise, from New York to Mumbai to Shanghai, and more thanThe climate crisis is driving sea level rise by the melting of ice sheets and glaciers and the thermal expansion of sea water.
Dr Taimoor Sohail, at the University of New South Wales, in Australia, and not part of the study, said: “The collapse of the west Antarctic ice sheet is a worrying climate tipping point. This assessment suggests that accelerated melting of ice shelves is locked in. The implications for sea-level rise are dire.”
