The ESA, European Space Agency, just released the
results of an 11 year study on the thickness of the ice sheets in Greenland.
While the edges of the sheets have been thinning was well known, the great interior was a mystery until now.

The result is a mixed picture, with a net increase of 6.4 centimetres per year in the interior area above 1500 metres elevation. Below that altitude, the elevation-change rate is minus 2.0 cm per year, broadly matching reported thinning in the ice-sheet margins. The trend below 1500 metres however does not include the steeply-sloping marginal areas where current altimeter data are unusable.

I'm surprised.
