This photo shows the Canadian Arctic community of Tuktoyaktuk in the Northwest Territories, Canada. Seas rising from global warming and land sinking as permafrost thaws are threatening the Canadian Arctic community. A beach barrier of small boulders has slowed the erosion of the peninsula (upper left). Geologists believe the protective Tuktoyaktuk Island (upper right) will erode away in 30-40 years, exposing the hamlet more to Arctic Ocean waves.
