A vast store of water equivalent in area to Ireland lies beneath Greenland's ice sheet, and may provide answers to one of the biggest riddles about climate change, scientists said on Sunday.

In 2011, US scientists crossed the southern Greenland ice sheet on an expedition to drill ice cores, a benchmark of annual snowfall.

They were stunned when they drilled into a layer of compressed snow called firn, for instead of piercing an icy sponge at a depth of 10 meters as expected, they encountered water and ice granules instead.
