shishmaref was a village in the furthest reaches of alaska. about 15 years ago, the people of the small, oceanfront hunting village noticed something odd. the ice that surrounded and protected the village began melting. as the ice continued to melt away at an alarming pace during the 1990s, the village began to lose the protection and could be easily damaged by storm waves. in 1997, the town completely lost a 125­foot­wide strip of land at its northern edge. in 2001, a storm with 12­foot­high waves destroyed dozens of homes. and finally, in the summer of 2002, with the situation getting worse, the residents were forced to move their entire town miles inland.
