Recognizing the Arctic is changing rapidly the Summit convenes decision-makers on infrastructure investment, natural resources, policy and security. Rapid change in the Arctic due to melting sea ice brings new opportunities and challenges. To address the complex Arctic agenda, an influential mix of international, U.S. and local leaders will convene at the second Arctic Imperative Summit, August 24–27, 2012, in Anchorage and Girdwood, Alaska. With a mission to sharpen the world's focus on the short-term opportunities and long-term challenges of Arctic development, the Summit features a multidisciplinary group of experts. By engaging with decision-makers from all sectors, Arctic leaders will be in a stronger position to influence responsible development decisions on their shores.
