COPENHAGEN—One thing is clear under this city's low, leaden skies: a ton of carbon dioxide emitted in India is the same as a ton of carbon dioxide emitted in the U.S. And while some notable contrarians are present here at the United Nations' climate summit, their presence is not felt as all those countries that do not rely on oil accept the basic physics of a molecule of carbon dioxide trapping heat in the atmosphere. But what is less clear is how the various negotiators from 193 countries are incorporating new developments in the scientific understanding of climate change and its progress, particularly as various draft texts of what an agreement might look like circulate through the crowded halls of the Bella Center.
