Earth-orbiting satellites are watching Antarctica thaw.
Eighty scientists from over 40 earth sciences agencies, including NASA and the European Space Agency, used satellite data from between 1992 to 2017 to find that Antarctica has lost three trillion tons of ice to the oceans over this 25-year period.
Their research, published Wednesday in the journal Nature, confirms a troubling trend, as much of the world's fresh water is frozen away in Antarctica. It's accelerating melt will likely play a primary role in swelling Earth's oceans two or three feet higher this century, or perhaps as much as six feet.
