What happens when one injects sulfate particles or aerosols into the atmosphere? Will it cause cooling (as seen with naturally occurring volcanic eruptions or will it cause harm to the ozone or other atmospheric variables? No one really knows for sure. Anderson, a professor at Harvard of atmospheric chemistry, said that he has a proposed project idea to spray a small amount of chemicals into the air to test their effect on free radicals that could destroy ozone. That’s because the aerosols may increase the reactive surface area for the conversion of chlorine (present from the release of now-banned chlorofluorocarbons) to a form that destroys ozone. The question is, how much ozone would be lost, and what benefit would be gained in the process?
