Antarctica’s ice is melting more than six times faster than it did in the 1980s, according to a new study published this month in the Proceedings of the National Academy of Sciences.

In the study, glaciologists from the University of California, Irvine, NASA's Jet Propulsion Laboratory and the Netherlands' Utrecht University used aerial photographs, satellite measurements and computer models to determine how fast the ice on southernmost continent and the site of the South Pole has been melting since 1979 in 176 of Antarctica's geologic structural basins, where ice drains into the Southern Ocean.
