Estimates derived from satellite measurements[5] show that between 1992 and 2017, the Greenland and Antarctic Ice Sheets lost a total of 6.4 trillion tonnes of ice, contributing 18 mm to global mean sea level rise. Ice losses from the Antarctic Ice Sheet have accelerated during recent decades, rising from 49 ± 67 Gt/yr between 1992 and 1997 to 219 ± 43 Gt/yr between 2012 and 2017. Ice losses from the Greenland Ice Sheet have also accelerated, rising from 46 ± 37 Gt/yr in the 1990s to 244 ± 28 Gt/yr between 2012 and 2017. This means a current global loss from both ice sheets of around 460 Gt per year, which roughly translates to 10 times the volume of Lake Garda, in Italy.
