How much ice will Greenland lose as the climate continues to warm? Processes in both the atmosphere and ocean are causing increased melt on the ice sheet surface, as well acceleration, thinning and retreat of fast-moving outlet glaciers that terminate in the sea. We particularly need a better understanding of the apparently diverse responses of such outlet glaciers to environmental change, the answer to which probably lies in poorly-known processes occurring at their beds and near their submarine termini.
