Warm Atlantic water is melting Greenland’s largest floating ice tongue

A team from the Alfred Wegener Institute found that warm Atlantic water is melting Greenland's 79° North Glacier, causing it to grow thinner. The study used a high-resolution ocean model to simulate the circulation below the ice tongue, revealing that higher ocean temperatures in the Atlantic are chiefly determining the melting rates.
