Poster's note : this has been lost in my drafts for literally 2 years, but
it's a good paper - so I'm sending it now.  The abstract's a bit thin, so
if someone's got a copy, it would be great to have on the list.

Abstract

The deliberate injection of particles into the stratosphere has been
suggested as a possible geoengineering scheme to mitigate the global
warming aspect of climate change. Injected particles scatter solar
radiation back to space and thus reduce the radiative balance of Earth.
Previous studies investigating this scheme have focused primarily on
sulphuric acid particles to mimic volcanic injections of stratospheric
aerosol. However, the composition and size of volcanic sulphuric acid
particles are far from optimal for scattering solar radiation. We show that
aerosols with other compositions, such as minerals, could be used to
dramatically increase the amount of light scatter achieved on a per mass
basis, thereby reducing the particle mass required for injection. The
chemical consequences of injecting such particles into the stratosphere are
discussed with regard to the fate of the ozone layer. Research questions
are identified with which to assess the feasibility of such geoengineering
schemes.
