For the fourth time since 2008 the Defense Department finds that climate change will exacerbate tensions and conflict.
In June 2008, the Department of Defense under then President George W. Bush published its 2008 National Defense Strategy. In this document was a single mention of climate change as one of trends and risks that could “pose a new range of challenges for states and societies” that “will affect existing security concerns such as international terrorism and weapons proliferation.”
Since then, the Department of Defense (DoD) has discussed climate change in major strategy documents three additional times. The latest, the 2014 Quadrennial Defense Review, was published today (March 4). In the executive summary to the Review, the DoD writes that
The impacts of climate change may increase the frequency, scale, and complexity of future missions, including defense support to civil authorities, while at the same time undermining the capacity of our domestic installations to support training activities.
