Greenland ice sheet melting at faster rate than previously thought

The combination of rising temperatures in both the air and oceans is leading to an effect similar to stirring ice in a drink, melting it faster than normal.

Greenland, the world's second-largest ice sheet, is even more in danger from global warming than previously believed.

The combination of rising temperatures in both the air and oceans is leading to an effect similar to stirring ice in a drink, melting it faster than normal, researchers from the University of Edinburgh and California San Diego found.
