"In 2009, President George W. Bush, signed National Security Presidential Directive -- 66/Homeland Security Presidential Directive -- 25. These established requirements for the U.S. to develop greater capabilities and capacity to protect United States air, land, and sea borders in the Arctic region. These directives also aim to increase Arctic maritime domain awareness and global mobility, requiring the U.S. to ensure a sovereign maritime presence in the Arctic. In May 2010 the U.S. Navy released its 'Strategic Objectives for the Arctic' in order to meet these national goals. To assess the impact of a changing climate on naval operations, Chief of Naval Operations Admiral Gary Roughead, created Task Force Climate Change in May 2009. The first goal of the task force was to develop and implement the Navy's Arctic Roadmap, a five-year plan to guide Navy policy, investment and actions. This report addresses Action Item 5.7 of the U.S. Navy Arctic Roadmap - to produce an Arctic Environmental Assessment and Outlook Report. This first biennial report provides a comprehensive assessment of the state of the Arctic environment, including the oceanography, hydrography, meteorology, fisheries, ice-extent, and climatic trends. This is important because the IPCC [Intergovernmental Panel on Climate Change] refresh rate is too long to meet the budget POM [Program Objective Memorandum] cycle, so this assessment will periodically synthesize existing scientific reports to inform POMs, specifically POM-14; this allows the Navy's decisions to be based on sound science, and not use one source only, but a consensus of accepted sources."
