Military Advisory Board
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." 
The CNA Military Advisory Board looked at the conditions climate changes are likely to produce, how those conditions may affect America’s national security interests, and what actions the nation should take to address these consequences. Its principal findings included the following:
- Projected climate change poses a serious threat to America’s national security.
- Climate change acts as a threat multiplier for instability in some of the most volatile regions of the world.
- Climate change, national security, and energy dependence are a related set of global challenges.
Recommendations Based on these findings, the Board made several recommendations, including the following:
- The national security consequences of climate change should be fully integrated into national security and national defense strategies. The intelligence community should incorporate climate consequences into its National Intelligence Estimate.
- The U.S. should commit to a stronger national and international role to help stabilize climate change at levels that will avoid significant disruption to global security and stability.
- The U.S. should commit to global partnerships that help less developed nations build the capacity and resiliency to better manage climate impacts.
- The Department of Defense should enhance its operational capability by accelerating the adoption of improved business processes and innovative technologies that result in improved U.S. combat power through energy efficiency.
- The Department of Defense should conduct an assessment of the impact on U.S. military installations worldwide of rising sea levels, extreme weather events, and other projected climate change impacts over the next 30 to 40 years.

Morrow Cater, founding principal of Cater Communications, has served as a strategic communication advisor to the MAB, including managing the media release of several of their influential reports on the link between climate change, energy, and national security. Her company has also helped organize dozens of state visits featuring MAB members who discuss national security and climate change issues with policymakers, business and community leaders, and the media.
