The children of one small town in northern Canada are on the front lines of climate change. In Arviat (map), a hamlet of 2,300 people in the Canadian territory of Nunavut, that means no outdoor trick-or-treating this year for the first time.

Over the last several years, shore ice has diminished along the western edge of Hudson Bay, forcing the annual polar bear migration closer and closer to town. That means bear-human run-ins have become increasingly common. Arviat is now a town under siege by polar bears.

Not your usual excuse for bringing kids indoors for Halloween, I am forced to acknowledge.
