Governments with borders along the Arctic Circle and major global maritime shippers are scrambling to take advantage of the relatively recent opportunity to move cargo across the top of the world.
Check out this map. It used to be that the Arctic Ocean ice extended as far as the area covered in both blue and pink. In other words, the extent of the ice was so great that it was not possible for freighters to sail along the northern coast of Russia or the northern coasts of Alaska and Canada.
