The BBC recently produced several videos that should alert Canadians and Americans to the possibility that they may be frozen out of Arctic exploitation. Russians have claimed both the Lomonosov Ridge, and the North Pole.
Russia is building floating nuclear power stations for use in the Arctic Ocean. The video shows one of the stations being built at St. Petersburg.
From the linked video and article here, other BBC News stories and videos about Russian use of the Northwest Passage for shipping, the melting of polar ice, etc., may be found.
