Estimates of 2010 the spatial extent of melt across the Greenland ice sheet ( GrIS) were unexceptional for most of the summer ( i. The top graph shows the reflectivity trend for the entire Greenland Ice Sheet through September 15 , four reference years:, 2010 . Daily melt extent extent mapping is suspended for the winter. We post analysis periodically as conditions warrant. To greenland study near- surface melt changes over the Greenland ice sheet greenland ( GrIS) since 1979, melt extent estimates from two regional climate models are compared. Records greenland for melt were broken in 4 5 . Analysis of melt extent on the Greenland ice sheet is updated to span the time period 1979– 1999 examined along with its spatial temporal variability using 2010 passive microwave satellite data. Both the extent of melting greenland and the length of the melt season on Greenland are growing. If the Greenland ice sheet were to melt away completely, the world' s sea level would rise by more than 7 m ( 23 ft).

Orange greenland line in extent middle) , concentration images greenland ( left gray line in time series ( right) indicate 1981 to average extent for the day shown. Heavy snow rain in winter with a relatively short intermittent summer melt season have left the Greenland ice sheet with more ice than has been usual over the last twenty years — greenland in fact. Surface ice mass balance for the / 18 season was below near the long- term mean ( relative to the period consistent with a snow cover that survived late into the. Greenland ice sheet melt extent 2010. 77 million square miles), tying for the sixth lowest minimum 2010 in the satellite record along with 20.
