Open Northwest Passage. Satellite image of the Canadian Arctic Archipelago taken on the 3rd August 2012. Sea ice has receded enough to open up the route,which connects the Atlantic and Pacific Oceans. The Northwest Passage opened for the first time in 2007. Since then a species of plankton that was exclusively found in the Pacific has been found in the North Atlantic. There is also evidence that Pacific and Atlantic populations of bowhead whales have begun to overlap. The declining sea ice is due to global warming,the Arctic temperature having risen by 1.7-2.2 degrees Celsius in the past century.
