Quote of the day – macroeconomics and climate science

From Arnold Kling (emphasis mine)

I am a macroeconomics skeptic. I think that my background in the subject is deep enough that my reasons for skepticism are legitimate. See, for example, my memoirs of a would-be macroeconomist.

I am a climate science skeptic, but not based on a similarly deep background. I just look at the superficial similarities with macroeconomics and infer that skepticism is warranted. It is plausible to me that the climate “consensus” is way off. However, it could be off in either direction–maybe the temperature increase will be faster and sharper than the consensus forecast.

When it comes to the differences between macro and climate science, points (1) and (2) favor climate science. However, point (3) leans against climate science. Good ideas are persuasive. If you need to excommunicate unbelievers, you are dealing in religion, not science.
