Well, I don't know how I drifted from the point that CO₂ is NOT a pollutant. It's a necessary part of the ecosphere that life can't exist without, all of it being carbon-based. We can have a lot more CO₂ in the atmosphere than right now without it being harmful. The science of "doom" is just bad science, and the CC models are lacking real world examples--we don't know for sure what will happen if things change.

Inert gases such as CO2, argon, nitrogen and helium are not poisonous, no more than is a pillow, but if you have no oxygen going into your lungs, you will smother.

Example: N2 is 78% of the atmosphere, a pretty high percentage, but we get by just fine with the available oxygen.

On the other hand, carbon monoxide is genuinely poisonous.
