> Single vulcano explosion releases more CO2 than entire mankind in a decade. I don't believe this is true. Dixie Lee Ray made a claim similar to this in her book Trashing the Planet (regarding the 1991 Mt. Pinatubo eruption) and Rush Limbaugh picked it up, but IIRC the original claim was based on a math error and a very questionable source. What is actually true that the Pinatubo explosion temporarily cooled the planet by much more than the predicted effect of a decade's worth of CO2 output. But it wasn't the CO2 output that did that. http://en.wikipedia.org/wiki/Mount_Pinatubo http://en.wikipedia.org/wiki/Mount_Pinatubo
