Projections of the future Photo: New Scientist , 2007 ‘ The near coincidence of the ice acceleration with the duration of surface melting, followed by deceleration after the melting ceases, indicates that glacial sliding is enhanced by rapid migration of surface meltwater to the ice-bedrock interface.’ Zwally et al., 2002. Surface Melt–Induced Acceleration of Greenland Ice-Sheet Flow. Science , 297 : 218-222.
