Antarctica as a whole went from losing about 40 gigatons of ice per year in the 1980s to 252 gigatons per year over the last decade. (One gigaton is a billion tons.) All that ice dumped into the ocean has raised global sea levels by 14 millimeters since 1979, according to the study. West Antarctica, home to some of the fastest-flowing and fastest-melting glaciers, accounts for the bulk of the loss calculated in the new work.
