After Greenland spent a good portion of July on fire, last week’s heatwave similarly scorched the country’s ice sheet.br According to Gizmodo Earther, the heat triggered a meltdown affecting roughly 60 percent of its surface.br On Thursday alone, new data shows the ice shelf lost 12.5 billion tons to surface melting.br That's the largest single-day loss in recorded history.br In 2012, Greenland's ice sheet sent more than 10 billion tons of runoff into the ocean.
