In doing so we'll also prevent some 1.5 million premature deaths
annually due to improved air quality.Soot Comes Out of the Atmosphere in Weeks, Not Decades Since soot — which in this context comes from older diesel engines and burning other fossil fuels, industrial sources, inefficient biomass cookstoves used in many developing nations — comes out of the atmosphere in a matter of weeks, not decades or centuries like carbon dioxide or other greenhouse gases, removing the source of
pollution is highly effective in both stopping the
warming effects as well as improving air quality.
