ICESat-2 laser-scanning satellite tracks how billions of tons of polar ice are lost
This color-coded map shows the amount of ice gained or lost by Antarctica between 2003 and 2019. Dark reds and purples show large average rates of ice loss near the Antarctic coast, while blues show smaller rates of ice gain in the interior.
