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...

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

China has the capacity to lead in carbon trading

Nature: The value of the worlds carbon market fell for the first time last year. More than one-third was wiped from the price of carbon credits in a plunge that reflects the continued global economic crisis and uncertainty over the future of emissions-trading schemes. Is it a good time to buy carbon credits? Perhaps not yet, but some shoots of recovery are visible, not least in my own country of China. Largely unnoticed in the West, Chinese carbon trading is getting up and running. In just two years,...

Black carbon a powerful climate pollutant: international study
2013-01-15 19:36:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: Black carbon, the soot produced by burning fossil fuels and biomass, is a more potent atmospheric pollutant than previously thought, according to a four-year international study released on Tuesday. Emitted by diesel engines, brick kilns and wood-fired cookstoves, black carbon is second only to carbon dioxide as the most powerful climate pollutant, according to the study published in the Journal of Geophysical Research-Atmospheres. But because black carbon only lasts in the atmosphere a matter...

Black carbon causes twice as much global warming than previously thought
2013-01-15 18:17:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: Soot from burned wood and diesel exhausts may have twice the impact on global warming than previously thought, according to a new study published on Tuesday. The "black carbon" is said to be the second most important man-made agent of climate change. The findings, published in the Journal of Geophysical Research Atmospheres, suggest there may be untapped potential to curb global warming by reducing soot emissions. Huge quantities of man-made soot enter the atmosphere every year. Around 7.5m...
