摘要:
The nature of the response of the Greenland ice sheet (GIS) to climate change is a fundamental question in climate science, but the details remain unclear. During the Holocene climate optimum 6,000 to 9,000 years ago, for example, many locations in the Northern Hemisphere showed unusual warmth yet changes in Greenland appeared inconsistent. Vinther et al. now standardize the previously disparate-seeming ice core records of climate history on the GIS during the Holocene and find consistent evidence for a stronger climate optimum than was previously recognized, together with elevation reduction and marginal ice sheet thinning.
