Study Finds Heat Flow From Earth's Mantle Contributes to Greenland Ice Melt

Monday August 12, 3pm

From: ENN, The Guardian, Inhabitat, Green Car Congress

The Greenland ice sheet is melting from below, caused by a high heat flow from the mantle into the lithosphere. ¹

As humans put more and more heat-trapping gases into the atmosphere, the Earth's climate changes ; we all know that. ²

Over the past few decades, satellite information has been gathered which shows huge declines in ice extent (the area covered by ice). ²

Every year, Greenland loses 227 gigatons of ice, contributing 0.7 millimeters to the overall annual sea rise of 3 milimeters. ³

Until now, climate modeling data has mostly focused on the impact of global warming without considering the effect of heat traveling into the lithosphere. ³

The continental ice sheets play a central role in climate ; interactions and feedback processes between ice and temperature rise are complex and still a current research topic. ⁴
