Melting Rate Of Icecaps In Greenland And Western Antarctica Lower Than Expected

This artist's concept shows GRACE's twin satellites, which orbit Earth in a back-to-back manner and change positions in response to variations in Earth's gravity field. The GRACE satellites house microwave ranging systems that measure the change in the distance between the satellites over time, enabling them to essentially "weigh" the changes in glaciers.

From Science Daily:

ScienceDaily (Sep. 7, 2010) — The Greenland and West Antarctic ice caps are melting at half the speed previously predicted, according to analysis of recent satellite data.

The finding is the result of research by a joint US/Dutch team from the Jet Propulsion Laboratory, Delft University of Technology (TU Delft, The Netherlands) and SRON Netherlands Institute for Space Research. The scientists have published their work in the September issue of Nature Geoscience.
