Short summary
In light of recent large-scale melting of the Greenland ice sheet (GrIS), e.g., in the summer of 2012 several days with surface melt on the entire ice sheet (including elevations above 3000 m), we use computer simulations to estimate the amount of melt during a warmer-than-present period of the past. Our simulations show more extensive melt than today. This is important for the interpretation of ice cores which are used to reconstruct the evolution of the ice sheet and the climate.
