Black Carbon: Golden Opportunity? http://apocadocs.com/s.pl?1374169062
Soot is second only to CO2 in creating climate-changing conditions -- and so offers big hope for reducing the threat... We've known for some time that black carbon plays a role in climate change, but such a complicated one that it's difficult to define or quantify. In January of this year, 31 scientists published the results of a four-year collaboration to analyze and synthesize what we know about black carbon's contributions in the Journal of Geophysical Research: Atmospheres. Their key finding? "We were underestimating warming via black carbon by a factor of two," says Patricia Quinn, an atmospheric chemist who contributed to the study.
Black carbon, in other words, is a much more important player in climate change than once thought. In fact, the study found that it is the second largest contributor after carbon dioxide, trapping more heat than methane, which was previously thought to be second.
