re: Found while searching for info on atmospheric soot...
Besides health and air pollution problems, soot (I believe and have read in different sources) is a top contributor (ok, human based contributor) of global warming/greenhouse gas. I don't think we'd have another ice age if soot was reduced from our atmosphere, but it would be a bit cooler. lol
Good article: http://www.catiusa.com/articles.html.htm
You may want to give 'EPA + soot + global warming' a try on Google.
