U.S. President Barack Obama (L) takes a boat tour of Kenai Fjords National Park in Seward, Alaska September 1, 2015. Obama on Tuesday proposed a faster timetable for buying a new heavy icebreaker for the U.S. Arctic, where quickly melting sea ice has spurred more maritime traffic and the United States has fallen far behind Russian resources.
