The NorthWest Passage is a proposed shipping route from the Atlantic to the Pacific through the
    Arctic Archipelago of Canada.
From the 15th Century Europeans have searched for such a commercial shipping route.
In the summer of 2000 several ships took advantage of the thinning Arctic ice to make this passage.
   Global warming is assumed to be the cause and it is likely commercial shipping will take advantage
   of the new NorthWest Passage.
