The collapse of a major polar ice sheet will not raise global sea levels as much as previous projections suggest, a team of scientists has calculated.
Writing in Science, the researchers said that the demise of the West Antarctic Ice Sheet (WAIS) would result in a sea level rise of 3.3m (10 ft).
Previous estimates had forecast a rise in the region of five to six metres.
However, they added, the rise would still pose a serious threat to major coastal cities, such as New York.
