Greenland’s ice sheet currently spans over 1.7 million square kilometers and is the largest freshwater reservoir in the northern hemisphere. The ice sheet has already lost over a trillion tonnes of its total mass since the 1980s, with melting rates six times higher in the last decade. Indeed, a recent study found that an average of 30 million tonnes of ice is now being lost every hour.
