Abstract:
Dust and soot might not be behind the observed darkening of the Greenland ice sheet.Tiny particles of dirt absorb sunlight that would be reflected into space by ice — contributing to local warming. Satellite measurements suggest that the amount of sunlight reflected by Greenland's icy surface has been decreasing since 2001.
