The CNA Military Advisory Board (MAB) is an American defense advisory group composed of retired three-star and four-star generals and admirals from the Army, Navy, Air Force, and Marine Corps that studies pressing issues of the day to assess their impact on America’s national security. CNA is a nonprofit research and analysis organization that operates the Center for Naval Analyses and the Institute for Public Research.
In April 2007, the MAB issued its first report entitled "National Security and the Threat of Climate Change." The report projects that climate change will pose a serious threat to America’s national security, especially by creating instability in already volatile regions.
In May 2009 the MAB issued a report that explores the impact of America's energy choices on our national security policies. This report, titled "Powering America’s Defense: Energy and the Risks to National Security," considers the security risks inherent in our current energy posture; energy choices the nation can make to enhance our national security; the impact of climate change on our energy choices and our national security; and the role the Department of Defense can play in the nation’s approach to energy security and climate change.
The MAB also released reports in 2010, 2011, and 2014 The May 2014 report, "National Security and the Accelerating Risks of Climate Change" re-examines the impact of climate change on U.S. national security.
The most recent MAB report, "National Security and Assured U.S. Electrical Power," was released in November 2015. The 2015 report found that "the current U.S. electrical grid – based on centralized power generation and interconnected and aging distribution architecture – is susceptible to a wide variety of threats."
