Science has moved well beyond simple correlation; in fact, the potential

You've evidently misread Arrhenius and Angstrom. They thought that
the absorption spectrum of CO2 in Earth's atmosphere was well beyond
saturation and that further increases in CO2 would have no effect.

I didn't mean to imply he had the science correct, only that the
potential was recognized. As I understand it, computing the effects of
the CO2 spectrum really needs a good computer, not hand calculations;
also, I don't think the spectra they had then were sufficiently accurate
to do it properly.

I mentioned Arrhenius just to inform folks that this is not something Al
Gore thought up a few years ago ;-)
