"Reporting from Copenhagen - International negotiators are quietly making progress here on steps to reduce "stealth" pollutants that contribute to climate change, including soot, refrigerants and methane gas, which together account for nearly as much greenhouse gas pollution as carbon dioxide.
"Carbon dioxide, of course, is the poster gas for global warming. Disagreements over how to reduce its emission from cars, factories and power plants have dominated the Copenhagen climate talks so far.
"But carbon dioxide accounts for only half the world's greenhouse gas emissions. And while top leaders postured and negotiated over a host of issues related to carbon emissions in the first week of the summit here, behind the scenes diplomats have worked toward compromises on a few simple strategies to reduce the other pollutants that cause global warming."
