Greenland Ice Sheet is hottest it has ever been and will cause sea levels to rise by 20in by 2100

Daily Mail  

The Greenland Ice Sheet is the hottest it has ever been and will cause global sea levels to rise by 20 inches by 2100 if it keeps warming at the same pace, scientists have warned. Concern: The Greenland Ice Sheet is the hottest it has ever been and will cause global sea levels to rise by 20 inches by 2100 if it keeps warming at the same pace, scientists warn From 2001 to 2011 temperatures at high elevations were 2.7°F warmer than in the 20th century, representing the warmest decade in the last thousand years HOW IS GLOBAL WARMING AFFECTING GLACIAL RETREAT? The Greenland Ice Sheet has an important role in the global climate owing to its size, radiative effects and storage of about three million cubic kilometres of freshwater. The calculations are based on a reconstruction of central-north Greenland temperatures from 1100 to 2011 undertaken by experts from the Alfred Wegener Institute The researchers expanded previous datasets on ice melting and temperatures at high elevations by redrilling the ice sheet during a series of expeditions up to 2012 Estimates: Temperatures were then reconstructed by measuring concentrations of stable oxygen isotopes within the ice, which vary with the temperatures at the time of ice formation In addition to estimating temperature changes, the team reconstructed how much the sheet has melted and found that it it has increased substantially since the 2000s, contributing to a rise in global sea levels.
