Pentagon: Climate change may worsen threats facing U.S.

WASHINGTON -- The United States Pentagon says climate change threats are being factored into planning, operations, and training across all branches of the military.

A 20-page report, out Monday, calls climate change a "threat multiplier."

It could even exacerbate many of the challenges the U.S. faces today, including infectious diseases and terrorism.

Defense Secretary Chuck Hagel wrote in the report that changing weather will make the world more unstable, and even increase challenges like hunger and poverty.
