Paul Krugman and the Non-Economics of Climate Change
Paul Krugman is a very smart guy. I get that. He is a Nobel laureate in economics, advises presidents and routinely appears on talk shows. The only thing we have in common is that we both have B.A.’s in economics. So it’s good to know that even he can go too far, like the rest of us mere mortals.
In an enlightening piece in the New York Times Magazine, Mr.
Krugman gives an 8000 word dissertation on the economics of climate change. Everyone should read it. He spends the first 2000 words discussing the types of economic solutions that can be used to address climate change and concludes that a workable, market-based approach to regulation, such as cap and trade, is the logical solution. It is a great explanation of a confusing subject. He should have stopped there. But he didn’t:
This is an article on climate economics, not climate science. But [insert Wilhelm Scream here] before we get to the economics, it’s worth establishing three things about the state of the scientific debate.
Mr. Krugman then feels compelled to discuss the science of climate change -- something in which he is not an expert. He makes the same conclusory statements that are the hallmark of climate change advocates and quickly falls into the compulsory lexicon of massive destruction:
“the upward trend [in temperature] is unmistakable”
“precipitation pattern will change . . . sea levels will rise”
"a rise in global temperatures that will be little short of apocalyptic"
“we will eventually face drastic changes in the climate”
“we’re talking about massively disruptive events, like the transformation of the Southwestern United States into a permanent dust bowl over the next few decades”
“avoiding planetary catastrophe is a lot more important”
It’s not that I disagree with any of his doom and gloom conclusions -- it’s that he isn’t a believable messenger. He doesn’t have the scientific background to support his statements. He’s just undermining his own credibility. And for what? Let others with the proper credentials get into that fight (and they will).
Now if Paul Krugman wants to opine on matters outside of his areas of expertise and wants to do so using incendiary and calamitous language, far be it from me to tell him otherwise. However, it will inevitably cause some people to view him as a politician rather than an economist. Once that happens, about half of the people will stop listening, no matter how much sense he makes. And that would be a catastrophe.

if the industrialized nations agree to limits but China and India won't come along, then China and India will have the ability to sell their products cheaper than the U.S.
the first move isn’t the end of the world, and an offer is made, and then countered, and on it goes until a resolution is reached. That first offer can take five minutes or five hours. It doesn’t matter too much to the mediator – he/she is being paid by the hour. And the mediator knows something the other two parties don’t; that is, sooner or later, someone will make the first offer.
