Greenland melt 'increases flood risk'
Greenland is now losing ice seven times faster than it was in the 1990s. The assessment comes from the Imbie group - an international team of polar scientists who've reviewed all the satellite observations of the past twenty-five years. They say Greenland's contribution to sea-level rise is now tracking the more pessimistic projections for future change. Team co-leader Prof Andy Shepherd spoke to our science correspondent Jonathan Amos.
