Abstract
Increased ablation under a greenhouse-effect climate is calculated by an energy-balance model for two sites at the margin of the Greenland ice sheet: Nordbogletscher, south Greenland, and Qamanarssup sermia, West Greenland. The summer temperature, with gradients of 0.43 and 0.57 m water a-1 deg-1 for Nordbogletscher and Qamanarssup sermia, respectively. However, the increase in ablation rate must be less in the higher parts of the ice sheet. A future climatic warming will therefore cause a rapid retreat of the ice-sheet margin and a steeper ice-sheet profile. -Authors
