Sea ice in the Arctic Circle is melting at a rate of 37,000 square kilometers per year (Two photos courtesy SHEBA Project Office, University of Washington) For the first time, scientists placed space based observations of Arctic sea ice retreats into a much longer term context, and have examined the likelihood that the sea ice decreases are in part because of human caused climate change.
