"Mellting over the Greenland ice sheet shattered the seasonal record on August 8 – a full four weeks before the close of the melting season, reports Marco Tedesco, assistant professor of Earth and atmospheric sciences at The City College of New York." '''

"The Greenland Ice Sheet is the second largest body of ice in the world. It spans over 1,710,000 square kilometers (660,235 square miles) which is around 80% of the surface of Greenland. The ice sheet is generally more than 2 km (1.24 mi) thick and over 3 km (1.86 mi) at its thickest point." During the summer (June to September), about 50% of the ice sheet's surface naturally melts. At high elevations, most of that melt water quickly refreezes in place. The melt water coming from the ice sheet that is near the coastal areas are retained by the sheet and the rest falls into the ocean." ...
...'This year, Greenland experienced extreme melting in nearly every region – the west, northwest and northeast of the continent – but especially at high elevations. In most years, the ice and snow at high elevations in southern Greenland melt for a few days at most. This year it has already gone on for two months.'
"We have to be careful because we are only talking about a couple of years and the history of Greenland happened over millennia," cautioned Professor Tedesco. "But as far as we know now, the warming that we see in the Artic is responsible for triggering processes that enhance melting and for the feedback mechanisms that keep it going. Looking over the past few years, the exception has become part of the norm."
