Tuvalu

Bad news for residents of Tuvalu, a small South Pacific nation with 11,500 people spread across nine atolls. Large parts of the country will disappear underwater later this week:

Over the last decade, successive Tuvalu leaders have claimed their state will be the first victim of sea level rise associated with global warming. They have used the argument to claim special immigration access to New Zealand and recently were in discussion with another Pacific state, Niue, on moving their people there.

Tuvalu is a fascinating little country and the title of this gem of a movie.
