A Smut Above: Unhealthy Soot in the Air Could Also Promote Global Warming
2013-01-19 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: Black carbon, commonly described as soot, may play a larger role in global warming than previously estimated, according to a new study. Every year in the Northern Hemisphere about 7.5 million metric tons of black carbon, the equivalent of more than 100 times Earth's total biomass, enters the air from internal combustion engines, forest fires and other sources. The fine material absorbs sunlight almost as well as carbon dioxide--a well-known greenhouse gas--and may contribute to accelerated snowmelts...

EPA Launches New Voluntary Program to Help Reduce Harmful Soot Pollution
2013-01-17 06:00:00| Industrial Newsroom - All News for Today
PM Advance, voluntary clean air program, helps communities continue to meet soot pollution standards, improve air quality, and protect public health. Focusing on working with communities to develop strategies for reducing harmful fine particle emissions, PM Advance requires participants to commit to taking such specific steps as putting school bus retrofit program or air quality action day program in place; EPA supplies technical advice, outreach information, and other support.

Soot is second biggest man-made contributor to global warming
2013-01-16 00:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Mongabay: Soot is the second largest man-made contributor to global warming, according to a comprehensive new study published in the Journal of Geophysical Research: Atmospheres. The research effectively doubles the estimate of soot's direct warming influence on climate. Soot is produced from the burning of diesel fuel, coal, charcoal, and wood. "Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Watts per square meter, approximately two-thirds...

Soot plays bigger role in warming
2013-01-15 19:00:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: New research says that black carbon, or soot, is making a much larger contribution to global warming than previously recognised. Scientists say that particles from diesel engines and wood burning could be having twice as much warming effect as assessed in past estimates. They say it ranks second only to carbon dioxide as the most important climate warming agent. The research has been published in the Journal of Geophysical Research-Atmospheres. Black carbon aerosols have been known to...
