Increasing rates of ice mass loss from the Greenland and Antarctic ice sheets revealed by GRACE

  title={Increasing rates of ice mass loss from the Greenland and Antarctic ice sheets revealed by GRACE},
  author={Isabella Velicogna},
[1] We use monthly measurements of time-variable gravity from the GRACE (Gravity Recovery and Climate Experiment) satellite gravity mission to determine the ice mass-loss for the Greenland and Antarctic Ice Sheets during the period between April 2002 and February 2009. We find that during this time period the mass loss of the ice sheets is not a constant, but accelerating with time, i.e., that the GRACE observations are better represented by a quadratic trend than by a linear one, implying that… CONTINUE READING
