Scientists say sea ice in the Arctic shrank to an all-time low of 1.32 million square miles on Sunday, Sept. 16, 2012, smashing old records for the critical climate indicator. That's 18 percent smaller than the previous record set in 2007. Records go back to 1979 based on satellite tracking." (AP Photo/U.S. National Snow and Ice Data Center)
