More than a dozen cities across North Carolina have joined an anti- global warming campaign led by the nation's mayors.
The communities signing the U-S Mayors Climate Protection Agreement promise to work to cut emissions of greenhouse gases to pre-1990 levels. Many scientists believe the gases speed potentially harmful climate changes.
Asheville, Durham, Wilmington and Winston-Salem are among the cities that have signed the initiative in North Carolina. Almost 450 cities have signed on nationally.
North Carolina mayors who have signed the initiative say they wanted to fill a void created by the federal government's inaction on the issue.
Supporters say the program is designed to get communities to set their own goals and make progress toward them.
