A report, “National Security and the Threat of Climate Change,” signed by eleven retired three-star and four-star admirals and generals for the CNA Corporation described climate change as a threat multiplier in already fragile regions, exacerbating conditions that lead to failed states — the breeding grounds for extremism and terrorism. They conclude that global climate change presents a serious national security threat which could impact Americans at home, U.S. military operations and heighten global tensions.

The report includes several formal findings:
· 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.
· Projected climate change will add to tensions even in stable regions of the world.
· Climate change, national security and energy dependence are a related set of global challenges.

The report also made several specific recommendations:
· The national security consequences of climate change should be fully integrated into national security and national defense strategies.
· The U.S. should commit to a stronger national and international role to help stabilize climate changes 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.
· DoD should conduct an assessment of the impact on US military installations worldwide of rising sea levels, extreme weather events, and other possible climate change impacts over the next thirty to forty years.
