Partitioning recent Greenland mass loss
Mass budget calculations, validated with satellite gravity observations [from the Gravity Recovery and Climate Experiment (GRACE) satellites], enable us to quantify the individual components of recent Greenland mass loss. The total 2000-2008 mass loss of -1500 gigatons, equivalent to 0.46 millimeter...
