title: CLIMATE CHANGE: Enhanced: The Greenland Ice Sheet Reacts.
abstract: 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.
