Climatology: Threatened loss of the Greenland ice-sheet
Jonathan M. Gregory1,2, Philippe Huybrechts3,4 & Sarah C. B. Raper4
Abstract
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 threshold.
