The response of the Greenland ice sheet (GIS) to changes in climate remains uncertain. During the Holocene climatic optimum — an unusually warm period from about 9,000 to 6,000 years ago — changes in Greenland appear inconsistent with the rest of the Northern Hemisphere. Here, the Greenland Holocene temperature history and the evolution of GIS surface elevation are extracted from four GIS locations; the results may resolve this disparity.
