Average annual CO2 from volcanos is only about 1% of what humans generate globally for CO2. While volcanos can certainly spew lots of stuff into the air when erupting, normally they are insignificant compared to human CO2 made output. CO2 from ice cores indicates a massive increase of atmospheric CO2 levels that coincide with the industrial revolution. This indicates almost certainly that human pertroleum use is responseable.
