The GRACE satellites continue to measure the change in gravity around the Greenland ice sheet. Here is the latest data showing the record amount of ice loss Greenland experienced in the 2010 summer. H/T to Tenney Naumer from Climate Change: The Next Generation and Dr John Wahr at the University of Colorado who analysed the GRACE data and granted permission to reproduce it here. Figure 1: Greenland ice mass anomaly – deviation from the...
Greenland rising faster as ice loss acceleratesWe have several independent lines of evidence that Greenland is losing ice at an accelerating rate. Satellite altimetry find glaciers are sliding faster downhill and dumping more ice into the ocean. Altimetry data also find the ice sheet is thinning. An overall picture is obtained by satellites measuring the gravity around the ice sheet. Another line of evidence has now been added to this picture with GPS measurements...
