Climate Change Correctness in the GOP

|


Not confusing science with policy.

Case Western Reserve University law professor Jonathan Adler has a sharp analysis over at the Volokh Conspiracy of what might be called Republican "Climate Change Derangement Syndrome." A recent outbreak occurred when Gov. Chris Christie (R) vetoed a bill that would have overturned his decision to withdraw from the Regional Greenhouse Gas Initiative, a cap-and-trade carbon rationing scheme adopted by several northeastern states. That's the right policy call. But then, as Adler explains

The problem, according to some conservatives, is that Christie accompanied his veto with a statement acknowledging that human activity is contributing to global climate change. Specifically, Christie explained that his original decision to withdraw from RGGI was not based upon any "quarrel" with the science.

While I acknowledge that the levels of carbon dioxide and other greenhouse gases in our atmosphere are increasing, that climate change is real, that human activity plays a role in these changes and that these changes are impacting our state, I simply disagree that RGGI is an effective mechanism for addressing global warming.

As Christie explained, RGGI is based upon faulty economic assumptions and "does nothing more than impose a tax on electricity" for no real environmental benefit. As he noted, "To be effective, greenhouse gas emissions must be addressed on a national and international scale."

Although Christie adopted the desired policy — withdrawing from RGGI — some conservatives are aghast that he would acknowledge a human contribution to global warming. According to one, this makes Christie "Part RINO. Part man. Only more RINO than man." ["RINO" as in "Republican in Name Only."]

Those attacking Christie are suggesting there is only one politically acceptable position on climate science — that one's ideological bona fides are to be determined by one's scientific beliefs, and not simply one's policy preferences. This is a problem on multiple levels. Among other things, it leads conservatives to embrace an anti-scientific know-nothingism whereby scientific claims are to be evaluated not by scientific evidence but their political implications. Thus climate science must be attacked because it provides a too ready justification for government regulation.   This is the same reason some conservatives attack evolution — they fear it undermines religious belief — and it is just as wrong.

Writing at MichelleMalkin.com, Doug Powers warns that " if some politicians think they can swim in the waters of AGW without getting wet or soaking taxpayers, they should think again." In other words, once you accept that human activity may be contributing to global warming, embracing costly and ill-advised regulatory measures is inevitable. Yet it is actually Powers, not Christie, who is embracing a dangerous premise. As Christie's veto shows, he understands that the threat of climate change does not justify any and all proposed policy responses. One can believe the threat is real, and still think cap-and-trade is a bad idea. Christie's critics, on the other hand, seem to accept that once it can be shown that human activity may be having potentially negative environmental effects, this alone justifies government intervention. Yet the environmental effects of human behavior are ubiquitous. Human civilization necessarily entails remaking the world around it. So if recognizing negative environmental effects leads inevitably to governmental intervention, there is virtually no end to what government needs to do, global warming or no. 

Adler concludes: 

As I've written before, it would be convenient if human activity did not contribute to global warming or otherwise create problems that are difficult to reconcile with libertarian preferences. But that's not the world we live in, and politicians should not be criticized for recognizing that fact.  Further, even if one accepts the "skeptic" perspective on climate change, there are still reasons to believe climate change is a problem, as I explain here. This does not require endorsing massive regulatory interventions or cap-and-trade schemes; there are alternatives.  In the end, politicians should be evaluated on their policy proposals — and commended for the courage to acknowledge politically inconvenient truths.

I agree.
