The South's governors worry that efforts to address climate change from carbon emissions could forsake their region's abundant coal, oil and gas supplies.
Former Senator John Warner of Virginia and retired Gen. Rich Engel told a Southern Governors Association panel Saturday global warming threatens peace worldwide and security in their states.
Former Senate Armed Services Committee chairman Warner said worldwide energy competition and more extreme weather will create new conflict and breeding grounds for terrorists.
Alabama Gov. Bob Riley and West Virginia Gov. Joe Manchin say clean energy proposals before Congress risk penalizing their states.
Manchin said the cap and trade bill provides too little aid for clean coal technology to keep coal competitive.
