I am 100% certain the link between CO2 and warming is complete BS.
Sorry, but wrong. The link is absolutely correct. The science is well known and incontrovertible. An increase in CO2 certainly DOES cause a retention of heat in the atmosphere. But the correct question is "HOW MUCH" is that CO2 induced warming effect compared to other factors. And the right answer is "not much at all".
