A little early to call the start of the #Greenland #meltSeason yet, but yesterday we calculate 10% of the ice sheet had melt at the surface - an impressive steep increase from 3% the day before!
The melt was accompanied by rain + snow though which adds to the #ice budget so the #IceSheet actually gained about 4 Gigatonnes..
