I heard this thing on the radio in some science program where somebody had a theory that you could reduce global warming by making a big volcano erupt. Sulphur dioxide gas is released by volcanoes and would supposedly reflect sunlight thus blocking it from coming into the lower atmosphere thereby cooling the Earth and countering the effects of global warming. What doesn't come in, can't be trapped.

My questions
- Is this an accepted theory amongst geologists?
- How would one go about making a volcano erupt? Detonate a nuclear device underground in the vicinity of a major volcano?
