The Greenland ice-sheet would melt faster in a warmer climate and is likely to be eliminated — except for residual glaciers in the mountains — if the annual average temperature in Greenland increases by more than about 3 °C. This could raise the global average sea-level by 7 metres over a period of 1,000 years or more. We show here that concentrations of greenhouse gases will probably have reached levels before the year 2100 that are sufficient to raise the temperature past this warming…

The Greenland Ice Sheet is thinning at an accelerating pace and the ice sheet’s contribution to sea-level rise has doubled in less than a decade. New data show rapid and widespread changes in the

Is the Greenland Ice Sheet in a state of collapse?

The Greenland Ice Sheet is thinning at an accelerating pace and the ice sheet's contribution to sea‐level rise has doubled in less than a decade. New data show rapid and widespread changes in the

The physics of ice sheets

The great ice sheets in Antarctica and Greenland are vast deposits of frozen freshwater that contain enough to raise sea level by approximately 70 m if they were to completely melt. Because of the

Glacier fluctuations and dynamics around the margin of the Greenland Ice Sheet

Greenland’s ice cover has undergone remarkable changes in the last two decades as a response to forcing from the atmosphere and ocean. This period coincides with the evolution of remote-sensing

Ice-Sheet and Sea-Level Changes

TLDR
Observational and modeling advances have reduced many uncertainties related to ice-sheets behavior, but recently detected, rapid ice-marginal changes contributing to sea-level rise may indicate greater ice-sheet sensitivity to warming than previously considered.

Climate code red: the case for a sustainability emergency

The extensive melting of Arctic sea-ice in the northern summer of 2007 starkly demonstrated that serious climate-change impacts are already happening, both more rapidly and at lower global

Large and irreversible future decline of the Greenland ice sheet

Abstract. We have studied the evolution of the Greenland ice sheet under a range of constant climates typical of those projected for the end of the present century using a dynamical ice sheet model

Recent Ice-Sheet Growth in the Interior of Greenland

TLDR
A continuous data set of Greenland Ice Sheet altimeter height from European Remote Sensing satellites (ERS-1 and ERS-2), 1992 to 2003, has been analyzed and winter elevation changes are shown to be linked to the North Atlantic Oscillation.

New calculations were performed to investigate the combined response of the Greenland and Antarctic ice sheets to a range of climatic warming scenarios over the next millennium. Use was made of fully

Climatic Impact of a Greenland Deglaciation and Its Possible Irreversibility

Warmer climate conditions persisting for a period of many centuries could lead to the disappearance of the Greenland ice sheet, with a related 7-m rise in sea level. The question is addressed of

Numerical computations are performed with the three-dimensional polythermal ice-sheet model SICOPOLIS in order to investigate the possible impact of a greenhouse-gas-induced climate change on the

Ice core work on Greenland has produced dramatic evidence for an instability of the climate system in the North Atlantic sector. In this paper, we provide climate modeling results indicating another
