   you might want to reconsider that...

   Volcanic Gases and Climate Change Overview   
      
   Volcanoes can impact climate change. During major explosive eruptions huge   
   amounts of volcanic gas, aerosol droplets, and ash are injected into the   
   stratosphere. Injected ash falls rapidly from the stratosphere -- most of it   
   is removed within several days to weeks -- and has little impact on climate   
   change. But volcanic gases like sulfur dioxide can cause global cooling, while   
   volcanic carbon dioxide, a greenhouse gas, has the potential to promote global   
   warming.

   personally speaking, i don't think i would like to live in an atmosphere of   
   sulfur dioxide, a toxic gas with a irritating, rotten and pungent smell...   
   current small concentrations of roughly 1 part per billion are ok for the most   
   part but more than that would be quite bad... especially considering that it   
   is a major pollutant and has severe impact on human, plant and animal health...
