By Barbara Swan Alliant Energy Alliant Energy is faced with the dual challenge of providing safe, reliable and affordable energy - in a time when demand is rising 2 to 3 percent each year - and protecting the environment.
A new federal science report noted heavy smog hanging over Beijing could heat up the weather in the American Midwest by three degrees over the next 50 years.
Tugboats puff out more soot for the amount of fuel used than other commercial vessels, and large cargo ships emit more than twice as much soot as previously estimated, according to the first extensive study of commercial vessel soot emissions.
Using sophisticated unmanned aircraft, research scientists at Scripps Institution of Oceanography, UC San Diego hope to assess Southern California's potential for climate change and better understand the sources of air pollution.
A handful of soil is a lot like a banana, strawberry and apple smoothie: Blended all together, it is hard to tell what's in there, especially if you have never tasted the fruits before.
Black carbon, the stuff that gives soot its dirty color, could be the second most important contributor to climate change after carbon dioxide and a key to preventing warming, at least in the short-run, a new study suggests. Black carbon is a type of aerosol - a small particle suspended in the atmosphere - that is produced in diesel exhaust and when wood, coal or other types of solid fuel are burned. Like other aerosols, soot particles absorb and scatter the sun's radiation; black...
Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to scientists.
A new NASA study estimates that most ground-level particulate pollution in the United States stems from regional sources in North America and only a small amount is brought to the country from other parts of the world.
Meeting in New York this month, dozens of big-city mayors from six continents competed to present the most ambitious plan for reducing emissions of carbon dioxide and other gases that cause global warming.
