The top U.N. official on climate change says the U.S. and China have moved closer on elements of a global warming agreement under discussion at a major conference next month.
Christiana Figueres says "there is a deal to be done" when delegates from most the world's countries convene in Cancun, Mexico. The two-week meeting begins Nov. 29.
She says the conference will not seek to complete a full climate change treaty, but will try to adopt decisions on several practical issues to slow the growth of heat-trapping greenhouse gases and to help countries brace for changes brought by a warming world.
She said in a conference call Wednesday the two main protagonists, the U.S. and China, "have moved toward each other" and are committed to reaching an agreement.
