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...
