One of the many ways in which the debate about “climate change” (as the climate catastrophists now describe their catastrophic and catastrophically silly opinions) is that those on the side of the free market who publicly surrendered to the climate catastrophists (back in the days when “climate change” was still known as “global warming”) are seeking to renegotiate their original surrender.
Most of us free marketeers started out reckoning that there might be something in all this Global Warming talk. At first we were ready to believe what we did not want to believe. But then we looked into it a bit, and we then concluded that what we wanted to believe was what we actually did believe, and now do believe with ever growing conviction. Climate catastrophism was and continues to be made-up nonsense. It was and is driven: by anti-capitalist lefties who found a substitute for their fading fantasy of mass human immiseration in another fantasy about an immiserated environment; by corrupted scientists looking to keep on feeding at the public trough; by corrupt businessmen ditto and on a far grander scale; and by media people looking for catastrophic headlines to grab attention, sell newspapers and boost hit-rates. With lots of overlap between these various categories, and probably with several more categories that I have temporarily forgotten about.
But a few free marketeers, either for tactical reasons or out of genuine conviction, continued to trust the climate catastrophists. One such was Tim Worstall, who now writes, at the Adam Smith Institute blog:
As you all know I’m boringly mainstream in my views over climate change. The scientists tell us that we’ve got to do something, the economists that that something is a carbon tax so I say, great, let’s have a carbon tax.
Or rather, that is what Worstall said at the start of his piece, but from which he then immediately starts to retreat. For his next sentence reads as follows:
And then we get information that rather changes this so far sterile debate:
He then quotes from the Wall Street Journal, on the subject of the latest pronouncement from the United Nations’ Intergovernmental Panel on Climate Change:
It puts the overall cost at less than 2% of GDP for a 2.5 degrees Centigrade (or 4.5 degrees Fahrenheit) temperature increase during this century. This is vastly less than the much heralded prediction of Lord Stern, who said climate change would cost 5%-20% of world GDP in his influential 2006 report for the British government.
In other words, the “climate orthodoxy” used to be that there was going to be a climate catastrophe, very soon, and people like Worstall said: Okay, so what do we do? But now, the more honest among the climate scientists, hammered away at for the last decade and more by their “climate skeptic” critics, are instead admitting that their precious catastrophe is, to put it mildly, unproven. There will be no catastrophe very soon, they now concede, and very possibly no catastrophe at all. We don’t know, really.
Which is exactly what that debate that Worstall says has been so “sterile” has been all about. It is understandable that Worstall wants to declare that a vitally important argument, full of sound and fury and signifying a hell of a lot, that he picked the wrong side of and has stayed on the wrong side of, year after year, was “sterile”, but this need not impress anyone else.
Finally, Tim Worstall has got the information.
Should the rest of us climate skeptics welcome Worstall, and all the other ex-swallowers of or ex-believers in immediate climate catastrophe, into the land of the sane, or continue to sneer at such people for having been so wrong for so long? Personally, as you can see, I choose to indulge in a little sneering. But I also note that this hideously belated and still absurdly muddled admission of error by Tim Worstall is yet one more sign that this highly significant debate continues to move in the right direction. The debate isn’t moving fast enough to save the world a huge slice of its wealth, with much more squandering to come. But, every little helps.
