Black Carbon More Powerful Contributor to Climate Change Than Previously Thought: New Study

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...

Black Carbon research fuels hopes of policy action

BusinessGreen: The prospects of an international crackdown on soot were given a boost this week, following the publication of new research suggesting so-called "black carbon" has double the climate change impact that was previously thought. The study, published in the Journal of Geophysical Research Atmospheres, saw over 30 leading scientists from around the world assess all the available data on the impact of soot from coal and wood burning and diesel engines on the climate. It concluded that the warming...
