Report: Climate change damaging more World Heritage sites

GENEVA -- Climate change is increasingly damaging the U.N.'s most cherished heritage sites, a leading conservation agency warned Wednesday, reporting that Australia's Great Barrier Reef and dozens of other natural wonders are facing severe threats.

Climate change that has lead to shrinking glaciers, increasing fires, floods and droughts, and the bleaching of coral reefs are among the troubles facing 83 of the 252 World Heritage Sites listed by UNESCO, the U.N.'s cultural agency.
