Global Warming in the Arctic

Arctic Ocean sea ice diminishes to record low

Arctic sea ice has now surpassed all previous records for the lowest absolute minimum summer extent. The "stunning record low" of 4.13 million square kilometers was recorded by satellite images on September 16, according to the National Snow and Ice Data Center. The previous record, 5.32 million square kilometers, was measured on September 20-21, 2005.

The minimum for 2007 is smaller by 1.19 million square kilometers (460,000 square miles) than the previous low, roughly the size of Texas and California combined, or nearly five United Kingdoms. This year also saw the extended opening of the Northwest Passage through islands north of Canada for the first time.
