Changes in the Arctic: Background and Issues for Congress
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 May 10, 2013, the Obama Admini...

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 May 10, 2013, the Obama Administration released a national strategy document for the Arctic region. 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.
