 BARCELONA, Spain (AP) - Negotiators at a U.N. climate conference in Spain further defined plans for reducing greenhouse emissions and continued work on a draft climate change treaty, with next month's deadline for a legal document increasingly in doubt.
Swedish Prime Minister Fredrik Reinfeldt, whose country holds the European Union presidency, said the holdup in the U.S. Senate of a climate bill made it impossible to meet a deadline next month for adopting a binding agreement regulating the world's emissions of gases that cause global warming.
A flurry of diplomatic activity reflected high tensions worldwide as two years of negotiations approach a climax at a major climate conference opening Dec. 7 in Copenhagen.
