UN: Pope's encyclical may have "major impact" on climate talks

Pope Francis is likely to have a major impact in spurring U.N. negotiations on global warming with an encyclical on the environment next week, the U.N.'s climate chief said on Thursday.

"Pope Francis is personally committed to this issue like no other pope before him," Christiana Figueres told a news conference at June 1-11 talks on a deal to combat climate change due to be agreed in Paris in December.
