(Delft University of Technology) The Greenland and West Antarctic ice caps are melting at half the speed previously predicted. This finding has emerged from research by a joint US/Dutch team from the Jet Propulsion Laboratory, Delft University of Technology and SRON Netherlands Institute for Space Research. The scientists have published their findings in the September issue of Nature Geoscience.

New research results are revealing surprising patterns of melting during the last interglacial period that suggest that Greenland's ice may be more stable -- and Antarctica's less stable -- than many thought.

A key glacier in Greenland is melting faster than previously expected, according to new findings. Researchers found that Greenland's longest-observed glacier, Mittivakkat Glacier, made two consecutive record losses in mass observations for 2010 and 2011.

The Greenland and Antarctic ice sheets are losing mass at an accelerating pace, according to a new satellite study. The findings of the study -- the longest to date of changes in polar ice sheet mass -- suggest these ice sheets are overtaking ice loss from Earth's mountain glaciers and ice caps to become the dominant contributor to global sea level rise, much sooner than model forecasts have predicted.

Satellite observations and a state-of-the art regional atmospheric model have independently confirmed that the Greenland ice sheet is losing mass at an accelerating rate, reports a new study in Science. This mass loss is equally distributed between increased iceberg production, driven by acceleration of Greenland's fast-flowing outlet glaciers, and increased meltwater production at the ice sheet surface.

The Greenland ice sheet can experience extreme melting even when temperatures don't hit record highs, according to a new analysis by Dr. Marco Tedesco, assistant professor in the Department of Earth and Atmospheric Sciences at the City College of New York. His findings suggest that glaciers could undergo a self-amplifying cycle of melting and warming that would be difficult to halt.
