If volcanoes weren't such an insignificant source of CO2 compared to human emissions, that might have made sense.
Don't you mean to say "mans emissions are insignificant compared to natural sources." After all, man's contribution to the GLOBAL CO2 budget is 5% of the total. Totally insignificant in the overall scheme of things.
Outright lie.
The normal global budget of CO2 includes both emission and absorption. Prior to the use of fossil fuels, the norm for the amount of CO2 in the atmosphere for the last few thousand years was about 280 ppm. In other words, the emission and absorption balanced out. Today, after 200 years of intensive fossil fuel use, the amount of CO2 in the atmosphere is about 400 ppm. That is a 40% increase that we are responsible for.
