Sorry, but the dude is spot on. See in order to have a theory, the hypothesis must be proven. And unless you have that proof, which I know you don't, you have no theory. All you have is mumbo jumbo soup! So, let's have it, give us this experiment that proves that 120PPM of CO2 drives climate.
Who said the level of CO2 drives the Climate? If I put a NO booster on an gasoline engine does that make NO the primary driver of the engine? The extra CO2 gives the sun (the primary driving force for the climate) a little boost.
And has never been shown to be true. There is ZERO empirical data to support that thought.
And that is a lie.
