I don't disagree with basic thermodynamics. I just don't think that CO2 has the outsized effect purported in media. The largest effect of increased CO2 is more plant growth to use the excess carbon.
CO2 has a precisely quantifiable effect on the Earth's energy balance can be empirically proven by filling a chamber with CO2 and calculating its ability to absorb heat or computing a physical model.
You are disagreeing with thermodynamics, you're just insufficiently knowledgeable to understand it. The effects of CO2 to are exactly understood. The only debate amongst climate scientists is how that heat energy is distributed and how it affects other factors like albedo from ice and clouds, which has uncertainties but bounded uncertainties nontheless.
