People who live in the town of Utqiaġvik have seen dramatic effects of climate change during their lifetimes.
Utqiaġvik, formerly known as Barrow, sits right on the edge of the Arctic Ocean at the very top of Alaska. It's the northernmost town in the United States, and home to about 4,400. The coastline here used to be edged with sea ice for nearly the whole year. But that period is getting shorter and shorter, and as a result Utqiaġvik locals are dealing with coastal erosion and are changing how they hunt in the fall.
