[quote=http://volcanoes.usgs.gov/hazards/gas/climate.php] 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. [/quote] 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... )\/(ark ....
