Speeding Sea Ice (VIDEO)

Columbia Climate School

Caption

Arctic sea ice is now drifting faster and farther than it used to, potentially transporting more pollutants across national boundaries. This video shows ice traveling progressively farther afield between 1982 and 2012. (Ice formed in Russian waters is light blue; Iceland, yellow; Greenland, green; Canada, red; United States, dark blue.)
