Well any addition of CO2 to a constant mixture of gasses increases temperature.
But the fallacy is to point out that this is because of humans--when, actually, most of it is a natural processes. In addition to that, one can't claim that the Earth's atmosphere has always been a constant mixture.
I think we are adding to CO2 to some extent, but not that this is a bad thing. CO2 levels fell from >7000 to 275ppm pre-industrial- being depleted by plants down to a near starvation level, opening up vast deserts that used to be lush.
We are recycling a tiny part of that vital natural nutrient, -re greening the planet. As a tree hugger, I'm doing my part!
