If there were need to have a counteracting agent (that would not have long life span like CFC's), I would think that the carbon black could be used to trap heat. However, as an aerosol, it also acts as a condensing surface, creating cloud droplets, and if flushed to snow, darkening.
The toxicity could be an issue. Any ash can trap some extra heat, but it also acts as a shield cooling air below it. Its usefulness depends on altitude and whether a smog is an issue for the area where the counter-effect is sought. This just a brief thought what stuff I might deploy. kr, Albert > Date: Mon, 31 May 2010 14:56:14 -0700 > Subject: [geo] Hypothetical SRM Question > From: [email protected] > To: [email protected] > > Group members, > > I need help answering a hypothetical question about SRM > countermeasures.
