    Those hot days occurred before CO2 was below 350ppm but today you will pay.

That will cost money. They will pass that money on to consumers.”

    YOU will pay for the unproven hypothesis, theory, theorem, thesis, conjecture, supposition, speculation, postulation, postulate, proposition, premise, surmise, assumption, presumption, presupposition, notion, concept, idea, contention, opinion, view, belief, of global warming from excess CO2!

    Jinan Cao published contrarian analysis saying GHGs, CO2 in particular, help the atmosphere cool by enhancing radiation to space. Which is “consistent with” this post …
