Arctic ice has reformed rapidly this winter after a record summer low, but it still covers less of the Arctic Ocean than it did in previous decades, NASA scientists announced today in an update of the states of Arctic and Antarctic sea ice. March is the month where Arctic sea ice traditionally hits its highest extent after the Northern Hemisphere winter and Antarctic sea ice reaches its lowest extent. NASA satellites have monitored sea ice coverage over both poles for nearly 40 years. Arctic sea ice reached a record low this past summer, with 23 percent less sea ice cover than the previous record low and 39 percent less than the average amount that has previously spanned the Arctic Ocean in the summer months. This extraordinarily high melt opened the fabled Northwest Passage and spurred scientists' worries about whether the Arctic ice had reached a tipping point, where melting begins to spiral out of control. NASA's satellite observations sho
