An uncertain future for the Greenland ice sheet
Xavier Fettweis, a researcher at the Laboratory of Climatology and Topoclimatology of the University of Liege, has been studying the Greenland ice sheet for more than 10 years in an attempt to predict fluctuations in its surface mass balance (see also Greenland: the surface of the ice sheet is melting quicker than predicted). His recent work (1) shows that melt of the ice sheet is accelerating. The year 2012 can henceforth be considered as a record year for melting. A great deal of uncertainty surrounds the future of this floating island and the consequences of the flow of meltwater into the oceans.
