Oh, it's worse. Eunice Newton Foote linked the proportion of CO2 in the atmosphere to Earth's temperature, in her paper "Circumstances affecting the heat of the sun's rays."
In 1856.
In 1856.
"An atmosphere of that gas would give to our earth a high temperature; and if, as some suppose, at one period of its history, the air had mixed with it a larger proportion than at present, an increased temperature from its own action...must have necessarily resulted."
Mind you, John Tyndall generally gets credit for the foundational experiments for the greenhouse effect for his work performing essentially the same experiment as Eunice Newton Foote, three years later.
Hm... I can't imagine why.
Hm... I can't imagine why.
The point being, we've known CO2 was a greenhouse gas that could raise the temperature of the Earth since the middle of the 1800s.
None of this is new science.
