I didn't say that most of it comes form volcanos. I said the the Human
contribution is dwarfed by a good volcanic eruption, and yes CO2 is a
trace element in the atmosphere at just 0.039%. IIRC the definition of
Trace element is any thing less than 0.1% of a substance.

Your implication is that somehow our actions make a particularly large
difference is ludicrous, and always has been. We can create localized micro
climate changes. Very little more.
CO2 the common boogieman is a trace element. A good volcanic eruption will
add more to the atmosphere in one year than has the entire industrial
revolution, yet it the long run it barely registers.
The best predictor of future climate is the sunspot cycle yet most "climate scientests"
completely ignore it*, because we don't have a good idea of exactly why it works. But you know we
don't have a particularly good model of how anything in climate works. None of the common models
predict the future, none even reliably predict the past, unless you "massage" the data so
much it would make an Economist blush.
*That wasn't always the case, I remember learning about it in physical science
classes in Jr. High School.
