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...
