NASA released a video this week (above is a still) that shows how ocean currents are affecting the Antarctic ice shelves. The study used data from the Ice, Cloud and Elevation Satellite (ICESat), which orbited from 2003 to 2009 as part of the Earth Observing System. The full animation shows how warm ocean currents are causing substantial ice loss from underneath Antarctica, far more than warm air melting from the top down. Read more about the study and watch the video here.
