"The diminishment of Arctic sea ice has led to increased human activities in the Arctic, and has heightened interest in, and concerns about, the region's future. The United States, by virtue of Alaska, is an Arctic country and has substantial interests in the region. On January 21, 2015, President Obama issued an executive order for enhancing coordination of national efforts in the Arctic. The United States assumed the chairmanship of the Arctic Council on April 24, 2015, and will serve in that capacity for two years. Record low extents of Arctic sea ice over the past decade have focused scientific and policy attention on links to global climate change and projected ice-free seasons in the Arctic within decades. These changes have potential consequences for weather in the United States, access to mineral and biological resources in the Arctic, the economies and cultures of peoples in the region, and national security. The five Arctic coastal states--the United States, Canada, Russia, Norway, and Denmark (of which Greenland is a territory)--have made or are in the process of preparing submissions to the Commission on the Limits of the Continental Shelf regarding the outer limits of their extended continental shelves."
