UN climate chief calls on leaders to step in
Bonn - The UN's top climate official says the world's political leaders must step into climate negotiations in the next few months to sort out disputes over reducing greenhouse gas emissions.
Christiana Figueres says climate negotiators are working toward a global framework for emissions reductions.
Part of that framework requires nearly 40 industrial countries to extend commitments under the Kyoto Protocol that expire in 2012.
But that is linked to actions by big emitters like the United States, China and India.
Figueres said on Friday that heads of state will meet on the sidelines of the UN General Assembly in September to discuss global warming.
She said they will have to take political decisions before the next major conference in November.
