Melting ice sheet in Antarctica may impact sea level: Study

​London: Loss of ice in Antarctica caused by a warming ocean may result in rising global sea levels by three metres, warns a recent research. Scientists from the University of Edinburgh in Scotland were able to gauge how levels of ice that existed continuously for at least 1.4 million years covering the land have changed, the study said.

During the previous warm periods, a substantial amount of ice has been lost from the West Antarctic ice sheet by ocean melting, but it may have not melted entirely, the study indicated, suggesting that ice would have been lost from areas below sea level, but not on upland areas. The researchers studied the peaks protruding through ice in the Ellsworth Mountains, on the Atlantic flank of Antarctica.
