At the tip of a barrier island 80 miles above the Arctic Circle is a town on the island of Kivalina, home to 400 native Alaskan Inupiat residents. They, along with their school, post office, health clinic, grocery store, laundry, two churches and a bingo hall are sinking into the Chukchi Sea. Their town is melting. Over the past 50 years, their average temperature has risen more than three degrees Fahrenheit and in the autumn of 2007, the whole island was evacuated for a few weeks following a devastating storm.
