The U.N. climate secretariat said the pledges would bring those countries to 12-18 percent over the next decade. That could lead to runaway climate change, virtually ensuring that extreme events like Russia's current drought and the flooding in Pakistan will become more common. Some developing countries say the whole approach is wrong. Rather than letting countries decide how much each can reduce its emissions, the atmosphere should be seen as "carbon space" to be divided up equitably. The idea found its way at the Bonn talks into the "Shared Vision" draft. Advocates cite a study published last year in Nature magazine saying that to limit temperature increases this century below 2 degrees Centigrade (3.8 F), the world has a "carbon budget" of 750 gigatons of emissions by mid-century. This budget should be allocated according to population, factoring in how much countries historically have drawn on their account. Industrial countries have 16 percent of the world's population, but they "occupy" 74 percent of the carbon space, Bolivian delegate Pablo Solon said at a presentation for delegates. Rich countries already have filled the air with carbon, using up much of their budget. "If you spend all your salary in the first week you won't have anything left," Solon told reporters. Poor countries with huge populations say this method will let them build their economies and catch up. But rich countries dismiss the notion as unrealistic and designed to score points against the rich countries. Chief U.S. delegate Jonathan Pershing called it "completely impractical." Artur Runge-Metzger, of the European Commission, said any discussion of historical responsibility is "a cul de sac. It leads nowhere." Mexico's special climate ambassador Luis Alfonso de Alba said only a few countries are behind it. "The majority is talking about the transition toward a green economy, and that's more important politically and conceptually," he told The Associated Press.
