At the IMAX theatre at OMSI in Portland, Oregon I saw To the Arctic.
The movie contains lots of cute footage of polar bears and dramatic scenes (e.g., mass caribou migration) in the Arctic.
But, the strong and disturbing message of the film is the terrible consequences of global warming for the Arctic, especially for wildlife. The decreasing area of ice means reduced habitat, less availability of food, and longer migration times.
It is quite possible that by 2050 there will be no polar ice cap.
