Scientists have measured a significant decrease in the mass of the Greenland ice cap, using data from satellites that measures movement in Earth's mass. A team led by Dr. Isabella Velicogna of the University of Colorado, Boulder, found that Greenland's ice sheet decreased by 162 (plus or minus 22) cubic kilometers a year between 2002 and 2005. This is higher than all previously published estimates, and it represents a change of about 0.4 millimeters (.016 inches) per year to global sea level rise.
The first direct, comprehensive mass survey of the entire Greenland ice sheet updates findings published in the journal Geophysical Research Letters. Data was collected from the NASA/German Aerospace Center Gravity Recovery and Climate Experiment (GRACE) satellite.
