Kling compares global climate models to mid-60s macro models

Arnold Kling needles the global warming "consensus":

My concern is with how "scientific consensus" is reached. In economics in the 1960's, there was a "scientific consensus," embedded in sophisticated macro-econometric models, that inflation reflected a competition over income shares, and that government policies to interfere with wage- and price-setting were the solution. Milton Friedman's contrary views were outside the "scientific consensus."

. . .

Milton Friedman's dissenting views of 1967 are close to the consensus views today.

I wish that climate-change models did not remind me so much of macro-econometric models. I wish that the contempt that the Left expresses for dissenting views in climate science did not remind me of the contempt that the Left expressed for Milton Friedman.
