President Barack Obama headed to remote fly-in native villages of Alaska on Wednesday on a trek the White House hopes will bring attention to how climate change is affecting Americans.

Obama will become the first sitting U.S. president to visit a community north of the Arctic Circle when he flies into Kotzebue, an Arctic town of about 3,000 that is battling coastal erosion caused by rising seas.

Before going to Kotzebue, Obama went to Dillingham, home to one of the world's largest sockeye salmon fisheries, where residents are fighting the Pebble Mine copper and gold project that has been proposed by Northern Dynasty Minerals Ltd .
