Global Warming is Now Officially Considered a Threat to U.S. National Security – Homeland Security Digital Library

For the first time, Pentagon planners in 2010 will include climate change among the security threats identified in the Quadrennial Defense Review , the Congress-mandated report that updates Pentagon priorities every four years.

In the review, Pentagon officials conclude that climate change will act as an “accelerant of instability and conflict,” ultimately placing a burden on civilian institutions and militaries around the world.

The Defense Department also acknowledges in the QDR Review that climate change will affect the military’s operating environment, roles and missions. Climate-related changes include heavy downpours; rising temperature and sea level; rapidly retreating glaciers; thawing permafrost; and lengthening ice-free seasons in oceans, lakes or rivers.
