So actually that's Mt. St. Helens + other natural sources + man made Co2 ;)
Oh yea, stop posting Rush factoids ::)
volcanism produces about 3% of the total CO2 with the other 97% coming from man-made sources.
http://volcano.und.edu/vwdocs/frequent_questions/grp6/question1375.html
annual volcanic production of CO2: 130-230 million metric tons
annual human production of CO2: 22 billion metric tons
therefore human production of CO2 is at least 100 times greater than volcanic production
It would take “17,000 additional volcanoes like Kilauea” to emit the amount of CO2 produced by human activities.
