There are two clocks ticking for the god-fearing climate-conscious among us. The first counts down to Copenhagen, where on December 7 representatives from 192 countries will hammer out a successor to the Kyoto Protocol: a post-2012 global climate deal aimed at curbing greenhouse gases. The second hurtles us toward disaster, a "mankind-threatening juggernaut," the point at which atmospheric carbon dioxide exceeds a concentration of 450 parts per million. To the extent that global warming is contingent on carbon emissions, the tipping point will be determined at the UN Framework Conference for Climate Change (UNFCCC) in Copenhagen, the last stop on the Bali Roadmap toward what UNFCCC Executive Secretary Yvo de Boer has called "the most complex international agreement that history has ever seen."
