Political dramas are playing out over the Northwest Passage, igniting fresh strife regarding who owns northern waters and the numerous islands that are revealed as ice melts.
If you’d like a look at what’s happening by way of the now-familiar backward chronology of a blog, check out BBC News’ Diary: Taking the Northwest Passage. It chronicles an actual passage by David Shukman on board ship with the Canadian Coast Guard. He includes information about the disputes that have risen in the past and may again in the near future. Shukman also answers questions from readers, with the help of Professor Jean-Eric Tremblay, the chief scientist of the expedition, in Northwest Passage: Your questions answered.

He’s produced a set of images showing what he predicts some large coastal cities in the US will look like in 2030, with projected rising water levels due to global warming.
