By using a fiber-optic cable to detect tiny vibrations a mile below the surface, scientists discovered a surprising way that ice sheets move.

The loss of ice on Greenland has been behind a sea level rise of around 14mm since 1992, scientists have said. If the entire Greenland Ice Sheet was to melt, sea levels could rise

Greenland’s Ice Sheet is cracking open at the seams, literally falling apart at speeds indicative of the brutal and accelerating impact of global climate change. In just five years, 930 million cubic meters of crevasses opened up in the Greenland ice sheet.
