Increasing Greenland Melt

Marco Tedesco at the University of Maryland suggests a new technique for remote sensing of snowmelt atop the Greenland ice sheet. When he uses it, he reports:

Long-term results show that snowmelt extent has been increasing at a rate of ?40,000 Km2 per year for the past 14 years.
