The Greenland Ice Sheet holds a substantial part of Earth's fresh water, and melting of the sheet contributes to sea level rise. Dahl-Jensen discusses the reports by Krabill et al. and Thomas et al., which shed light on short- and long-term surface elevation changes of the ice sheet. Low-altitude areas are melting, but high-altitude areas show no net reduction over both the short and the long term.
格陵兰冰原储存了地球大部分的淡水，而冰原的融化导致海平面上升。Dahl-Jensen 讨论了 Krabill 等人和 Thomas 等人的报告，这些报告揭示了冰原短期和长期的表面高程变化。低海拔地区正在融化，但在短期和长期内，高海拔地区并没有出现净减少。
