By using eleven years of data collected by satellites from the European Space Agency (ESA), European researchers have found that the ice sheet covering the interior of Greenland has gotten thicker at a rate of more than 6 centimeters per year. Another analysis published three months ago shows similar results for Antarctica. While the edges of the glaciers are melting, the interiors are getting thicker. And even if it looks strange for non-specialists, it is completely coherent with the theories about global warming. Increases in temperatures mean more moisture -- or snow -- at high elevations. But these effects should be reversed in a few hundred years and sea levels will increase by at least seven meters for Greenland's melt only. Read more...
