"Climate change … may act as an accelerant of instability or conflict, placing a burden to respond on civilian institutions and militaries around the world."
- Department of Defense's Quadrennial Defense Review (PDF)
In February 2010, the Department of Defense released the Quadrennial Defense Review (QDR), declaring that climate change will play a “significant role in shaping the future security environment.” This is the first time the QDR has directly addressed the national security threat from climate change in its planning.
In 2007, Sens. John Warner (R-VA) and Hillary Rodham Clinton (D-NY), members of the Senate Armed Services Committee, added language to the 2008 National Defense Authorization Act requiring DoD to consider the effects of climate change on DoD facilities, capabilities and missions. Through the QDR, DoD is now considering and incorporating the threat of climate change in its long-range strategic plans.
A Strategy-Driven Process
DoD conducted the 2010 QDR from February 2009 through January 2010, beginning with an assessment of the emerging security landscape and the many ways in which the U.S. armed forces may be called on to protect and advance the nation's interests. In order to determine the mix of military capabilities best suited to supporting the nation's defense strategy, the QDR was analytically grounded. Secretary of Defense Robert M. Gates, advised by senior civilian and military leaders within the department, reviewed, modified and endorsed a set of scenarios that the QDR used to help evaluate current and potential future forces . The review provides the blueprint for what DoD will do over the next four years.
According to Michèle Flournoy, undersecretary of defense for policy, “The QDR may be the most important report DoD provides Congress. It really requires the department to step back and think strategically about the present and the future to set its priorities and objectives and then to connect those to the program and to the budget.”
The QDR, Energy and Climate Change
According to the 2010 QDR, climate change “will shape the operating environment, roles, and missions” that the department undertakes, and “DoD will need to adjust to the impacts of climate change on our facilities and military capabilities.”
