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.

Cox Nature Climate Change 2, 713–719 (2012) doi:10.1038/nclimate1528 Received 14 November 2011 Accepted 10 April 2012 Published online 12 August 2012 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.
