If the entire glacier in the northeast of Greenland melted, then global sea levels would rise by an astonishing 46 centimeters (18 inches). Unfortunately, it seems the rate at which this glacier, known as Zachariæ Isstrøm, is sliding into the ocean and breaking apart has dramatically increased since 2012. At its current rate, it is losing a worrying 4.5 billion tonnes (5 billion tons) of ice per year.
