"Global warming poses a "serious threat to America’s national security" and the U.S. likely will be dragged into fights over water and other shortages, top retired military leaders warn in a new report.

The report says that in the next 30 to 40 years there will be wars over water, increased hunger instability from worsening disease and rising sea levels and global warming-induced refugees. "The chaos that results can be an incubator of civil strife, genocide and the growth of terrorism," the 35-page report predicts.

The report was issued by the Alexandria, Virginia-based, national security think-tank The CNA Corporation and was written by six retired admirals and five retired generals. They warn of a future of rampant disease, water shortages and flooding that will make already dicey areas - such as the Middle East, Asia and Africa - even worse.
