"Pentagon, CIA Eye New Threat: Climate Change"

"Global warming is now officially considered a threat to U.S. national security.

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.

The reference to climate change follows the establishment in October of a new Center for the Study of Climate Change at the Central Intelligence Agency."
