Latest Black carbon Stories
Some past approaches to calculating the impacts of forest fires have grossly overestimated the number of live trees that burn up and the amount of carbon dioxide released into the atmosphere as a result.
A new modeling study from NASA confirms that when tiny air pollution particles we commonly call soot â€“ also known as black carbon â€“ travel along wind currents from densely populated south Asian cities and accumulate over a climate hotspot called the Tibetan Plateau, the result may be anything but inconsequential.
Black soot deposited on Tibetan glaciers has contributed significantly to the retreat of the world's largest non-polar ice masses.
GREENBELT, Md., Dec. 14 /PRNewswire-USNewswire/ -- A NASA-led study has found new evidence that a "heat pump" effect, driven by emissions of soot, or black carbon, contributes as much (or more) to atmospheric warming in the Himalayas as greenhouse gases.
WASHINGTON, Dec. 14 /PRNewswire-USNewswire/ -- Black soot deposited on Tibetan glaciers has contributed significantly to the retreat of the world's largest non-polar ice masses, according to new research by scientists from NASA and the Chinese Academy of Sciences.
Soot, ozone and methane need attention to deal with near term impacts on climate.
SAN FRANCISCO, Oct.
The air in Beijing during the 2008 Olympics was cleaner than the previous year's, due to aggressive efforts by the Chinese government to curtail traffic, increase emissions standards and halt construction in preparation for the games, according to a Cornell study.
Smokestack emissions from oceangoing ships will cause an estimated 87,000 deaths worldwide each year by 2012, U.S. researchers said. James Winebrake of the Rochester Institute of Technology and colleagues note that the current finding is almost one-third higher than previously believed.
