Scientists using satellite data to analyze thickness changes in the Greenland Ice Sheet have discovered that the amount of snow falling on the ice sheet interior actually increased by as much as 6 cm per year for the years 1992-2003, even as the edges of the ice sheet thinned. Changes in a regional atmospheric circulation pattern, the North Atlantic Oscillation (NAO), seem to be responsible for the snowfall increase. It's not clear what these findings might mean for long-term climate trends, but a temporary increase in regional snowfall is not inconsistent with global warming scenarios.

Warmer climate leads to... more snow in Greenland?
