Melting Arctic ice risks Canada-US territorial dispute - Yahoo! News
MONTREAL (AFP) - Global warming is melting the Arctic ice so fast that a new sea route is opening up between the Atlantic and the Pacific -- and with it the risk of a territorial dispute between Canada and the United States.
Temperatures around the North Pole are rising twice as fast as in the rest of the planet, according to UN and Canadian government experts.
By 2050, they warn, ships will be able to sail around northern Canada for most of the summer.
