By analysing high resolution satellite images, Carrivick and colleagues estimated that 11,000 sq miles (28,707 sq km) of Greenland's ice sheet and glaciers have melted over the last three decades.
Roughly, the whole country of Greenland is about 836,000 sq miles and the ice sheet covered 679,000 sq miles - about 81 per cent - in the 1980s. Now, a loss of 11,000 sq miles brings the total ice cover down to 79 per cent, which is not much difference percentage-wise, but in terms of size 'it is enormous', Dr. Carrivick said.
