Black carbon or soot is an aerosol that comes from the incomplete burning of fossil fuels, biofuels and biomass. Examples include cooking fires, forest fires and diesel truck exhaust. Scientists in the United States have alerted policy makers to the impacts of black carbon and efforts to control it have been undertaken. Black carbon does not stay in the atmosphere as long as carbon dioxide does. Black carbon impacts Earth’s atmosphere, human health, and Arctic ice and snow.
