In 1976, Robinson’s newsletter (ATE) published this rebuttal of the “greenhouse theory”:

THE GREENHOUSE EFFECT

I’ll let Ludwig do the detail exposition of his errors, but the point I want to make is that here is Robinson, in 1976, before Hansen or Gore started to publicize AGW, creating the very talking points one still finds today in the comments at HotWingNuts, TownHall, etc:

From the link:

It is true that the carbon dioxide content of the atmosphere has slightly increased in the last 100 years; but the evidence that this is due to human activity is, at best, very flimsy. (As usual, man’s activities are puny compared to the gigantic CO production be Mother Nature.)

and

The greenhouse effect is also genuine, as call be demonstrated with a piece of glass and a spectrometer. But it hardly affects the temperature of a greenhouse, which gets its warmth almost exclusively by the lack of ventilation - as proved in l909 by physicist R.W Wood, who covered one greenhouse with glass and another with rocksalt. which is transparent to all colors, including infrared.

and

The earth’s (cloudless) atmosphere is largely opaque to infrared already, trapping some of the earth’s heat radiation, and what effect an increased concentration of carbon dioxide might have on a circulating atmosphere, nobody knows for certain. But such an effect, if any, would be superimposed on the large climatic changes that take place over decades and centuries (unknown why) anyway, and the suspicion is that the corresponding (additional) greenhouse effect would have the same effect as on a greenhouse next to none.

That last one is in particular an especially strong FAIL.

Anyway, one again, the point is that 34 years ago Robinson (along with a few others) were already putting into motion the talking points used by the right-o-sphere today.
