Greenland melting due equally to global warming, natural variations

A canyon in the Greenland ice sheet filled with melt water in summer 2010.

Up to half of the recent warming in Greenland and surrounding areas may be due to climate variations that originate in the tropical Pacific and are not connected with the overall warming of the planet. Still, at least half the warming remains attributable to global warming caused by rising carbon dioxide emissions.
