Andy Crouch was kind enough to respond to my article on climate change (which itself was penned in reply to Crouch’s original piece), and I’ve included a response of my own. His words are in the large blocks of italics below:

While I’m disappointed that you don’t even try to engage the work of the Intergovernmental Panel on Climate Change, by far the most extensive and diligent effort I’m aware of to evaluate the science of global warming,

In my defense, I did refer to Sir John Houghton, co-chair of the Scientific Assessment Working Group of the Intergovernmental Panel on Climate Change. As an experienced writer, I’m sure you know of the necessary limits of a mentary piece. I chose to limit the scope of my piece to engage your original article.

If you would like to see me engage your claim that “there is in fact no serious disagreement among scientists that human beings are playing a major role in global warming,” I refer you to one of my responses on an earlier thread, wherein I cite the following statement from Hans von Storch, who heads the Coastal Research Institute of the GKSS Research Centre in Geesthacht, Germany: “A considerable number of climatologists are still by no means convinced that the fundamental questions have been adequately dealt with. Thus, in the last year a survey among climate researchers throughout the world found that a quarter of the respondents still harbor doubts about the human origin of the most recent climatic changes.”

There’s a lot more that could be said on the science of course. Suffice it to say that consensus (or even unanimity) of opinion among scientists does not rise to the level of establishing ontological truth. The majority can be, and often is, terribly wrong.

And since your piece really is more about the economic benefits of political action on climate change than the science (which you rather take for granted), I’m disappointed that you didn’t engage the work of the Copenhagen Consensus of 2004, whose “basic idea was to improve prioritization of the numerous problems the world faces, by gathering some of the world’s greatest economists to a meeting where some of the biggest challenges in the world would be assessed.”

what really disappoints ing from the Acton Institute, is your failure of economic imagination. Why should the action to mitigate global warming be a drain on economic resources? That has not been true of past major technological initiatives. I have every expectation that the world economy will *grow* as a result of the efforts to develop and transfer new technologies.

You may call it a “failure of economic imagination” to see the possible technological advances and innovations, but I question your optimism regarding the economic benefits of pursuing potential cures for a perceived problem that may or may not be caused by human activity. I would liken your argument to a sort of “broken window fallacy” writ large.

If you are disappointed by my lack of economic imagination, I in turn am disappointed by your lack of some basic economic understanding (e.g. opportunity cost). Your whole concept of an “environmental wager” is predicated on the concept that it doesn’t matter if Sir John and the IPCC are wrong about global warming, we’ll still be better off acting as if they were right even if they aren’t. The following thought experiment is intended to show why this just isn’t true. The science does matter…and so do economic costs.

To illustrate this with a bit of pop culture, we might think one day that a et is hurtling toward earth. Let’s say we’ve only got twenty years before impact. Naturally after the initial panic passes, e up with a plan. We have some time, so we get all our pointy-headed intellectuals together and invent some really et-busting technology. I mean real nice sci-fi stuff. We send out our mission and get all our lasers (or whatever else) ready, and let’s say we do all this in just ten years. We’ve got plenty of time. We’re set to go, but when it’s time to “ready, aim, fire,” we only get to “ready.” As we try to aim, we realize we were wrong. There is et (or there is et but it’s not heading towards us).

What’s the result? Yeah, we’ve got some really et-busting lasers. It might even be helpful to us if we want to build a Death Star. We employed a lot of pointy-headed intellectuals during those 10 years, so that’s good. Unemployment was down because everyone was working on et-busting laser. It’s all good right?

Take that, global warming!

I don’t think so. Maybe we stumble across some useful technological advances during the five years and in the course of spending billions if not trillions of dollars. But I don’t think we’ll accidentally stumble across the cure for AIDS, or the answer to malaria epidemics, or the means to clean water access, or the solution to political corruption in developing nations.

The point is our time, money, and resources can better be spent, right now, elsewhere. Maybe in twenty or fifty or a hundred years man-made global warming really will be a challenge…if we’re faithful with our resources and fight the problems we really have today, those later generations will be a lot better prepared to fight the problems of their day. If we squander our efforts on things that may or may not ever be real threats, then we can be sure that real people today will pay the price.

Furthermore, there is little need mand-and-control government policies — the creation of markets in carbon emissions should do much of the work very efficiently. I recently reviewed a study — I’ll try to track down the reference, but I’m traveling and don’t have it with me — suggesting that the Environmental Protection Act, which opponents at the time saw as a major threat to economic growth and jobs, actually *created* jobs and contributed to economic growth. And there is every reason to expect that policies to mitigate carbon emissions will be better designed to harness the energies of markets than the EPA.

I can agree with you that government policies that at least attempt to deal with the realities of the marketplace should be better than the EPA, again I’m not as optimistic that government-imposed carbon emission markets would “do much of the work very efficiently.” You can try to package the deal in market-friendly terminology, but the limits of emissions would still have to be set by governments. The Kyoto Protocol allows for “emissions trading,” but as this article title succinctly demonstrates, “CO2 market needs federal push to blossom.” For more on the future of cap and trade systems, see this article (Tech Central Station no longer active).

Really, if the science were so unsettled and the potential economic consequences so calamitous, why would corporations like BP, GE, and Shell (Shell!) be endorsing action on climate change? I believe they see tremendous economic opportunities in this area.

I can think of any number of reasons. For starters, such multi-nationals might think they perceive the handwriting on the wall, and that the kinds of regulatory standards that ing out of the EU and efforts like Kyoto will inevitably be enacted globally, and the US will eventually capitulate. They already have to meet standards in many other countries…so why not make those standards consistent across their own operations?

If they are right, it’s of course more valuable from a public relations standpoint to be at the forefront of the shift. Thus, panies like BP and GE make a point of mercials, wherein cute dancing baby elephants tell us about their “eco-magination.”

If BP, GE, and Shell want to take action on climate change, they should do so, and consumers who support their positions should make it a point to patronize their places of business. But panies are not only advocating for action on their own part, they are advocating for imposed action on everyone. That’s whole different ballgame.

If panies are right about climate change, then they’ll be richly rewarded for their business-savvy and their economic and technological imagination. If they’re wrong, then they’ll have wasted a lot of money and resources on not-immediately-useful technology. In either case, the market should be sufficient to reward or punish them. I don’t think we need mand-and-control government policies” on top of it.
