I think it was in SuperFreakanomics where they explored the viability of releasing the equivalent to volcano smoke into the atmosphere to shade the earth. The research was based on earth cooling after certain types of volcano eruptions.
I think the scientist conclusion was that it was pretty viable but introduces way too many other issues. The biggest being, who gets to control the earth thermostat.
