Sea level rise by 2100 'below 2m' :

Sea levels globally are very unlikely to rise by more than 2m (7ft) this century, scientists conclude.
Major increases would have to be fuelled by a faster flow of glaciers on the Greenland or Antarctic ice sheets.
But writing in the journal Science, a US team concludes that a rise of 2m would need glaciers to reach speeds that are "physically untenable".
However, even increases substantially less than 2m would cause major issues for many societies, they say.
"Even a sea level rise of 20cm (8in) in a century will have quite dramatic implications," said Shad O'Neel from the US Geological Service (USGS).
