Climate change is a stark reality in America's northernmost state. Nearly 90 percent of native Alaskan villages are on the coast, where dramatic erosion and floods have become a part of daily life.
Perched on the Ninglick River on the west coast of the state, the tiny town of Newtok may be the state's most vulnerable village. About 350 people live there, nearly all of them Yupik Eskimos. But the Ninglick is rapidly rising due to ice melt, and the U.S. Army Corps of Engineers says the highest point in the town — a school — could be underwater by 2017.
