Shock News : Greenland Has Been Cooling For 70 Years
Late season warmth extends 2013 Greenland melt season…briefly
August 28, 2013
Greenland’s surface ice melt season reached a peak in late July, coinciding with a period of very warm weather. Greenland’s melt season this year will be closer to average than was 2012, with far less melting in the northern ice sheet and at high elevations. Nevertheless, an all-time record high temperature for Greenland may have been set in 2013.

Greenland Ice Is Melting -- Even from Below: Heat Flow from the Mantle Contributes to the Ice Melt

sciencedaily.com

Aug. 11, 2013 — The Greenland ice sheet is melting from below, caused by a high heat flow from the mantle into the lithosphere. This influence is very variable spatially and has its origin in an exceptionally thin lithosphere. Consequently, there is an increased heat flow from the mantle and a complex interplay between this geothermal heating and the Greenland ice sheet. The international research initiative IceGeoHeat led by the GFZ German Research Centre for Geosciences establishes in the current online issue of Nature Geoscience that this effect cannot be neglected when modeling the ice sheet as part of a climate study.
