The glaciers of greenland are over a hot pan

The glaciers of Greenland are continually losing volume and extension.
But now the cause is not only of the global warming!
In fact, according to a recent study published on nature geoscience carried by an international researchers group,the ice does not melt only above but also from below from the heat of the earth in this region.
About the data collected the glacier-cap decreases every years even 227 tonn/years,
This discovery will have an important role in the future,specially into the prediction of climate models.
