Black Carbon More Powerful Contributor to Climate Change Than Previously Thought: New Study
2013-01-17 21:34:00| Climate Ark Climate Change & Global Warming Newsfeed
Huffington Post: Black carbon -- that nasty air pollution that causes major health problems -- also happens to be a very powerful contributor to climate change. In fact, a new multi-year international study has just found that it's the second most powerful contributor to climate change -- behind carbon dioxide emissions. Emissions from dirty diesel, residential cooking and heating and forest fires from deforestation are major contributors to black carbon pollution (see figure). Addressing black carbon emissions from...

Black carbon is worse for global warming than previously thought

Yale Environment 360: It rises from the chimneys of mansions and from simple hut stoves. It rises from forest fires and the tail pipes of diesel-fueled trucks rolling down the highway, and from brick kilns and ocean liners and gas flares. Every day, from every occupied continent, a curtain of soot rises into the sky. What soot does once it reaches the atmosphere has long been a hard question to answer. It's not that scientists don't know anything about the physics and chemistry of atmospheric soot. Just the opposite:...

EcoWatch: Thirteen years after Jim Hansen described the significant role of black carbon for climate stabilization,1 in a comprehensive assessment of black carbon and climate released on Jan. 15, a team of 31 worldwide experts have confirmed the importance to combating global warming by reducing black carbon from targeted pollution sources. Schematic overview of the primary black carbon emission sources and the processes that control the distribution of black carbon in the atmosphere and determine...
