Panetta: Climate change a national security threat

Defense Secretary Leon Panetta declared global warming a national security threat yesterday during a speech before an environmentalist group in Washington, D.C.

“The area of climate change has a dramatic impact on national security,” Panetta told the Environmental Defense Fund last night. “Rising sea levels, severe droughts, the melting of the polar caps, the more frequent and devastating natural disasters all raise demand for humanitarian assistance and disaster relief.”
