[Ed. note: This post complements that of Ken Green earlier this week, Five Climate Questions for Richard Muller (Temperature findings begin, not end, the real debate)]
The recent announcement of the results of the Berkeley Earth Surface Temperature (BEST) Project by project chairman Richard Muller has caused quite a stir. True believers in catastrophic anthropogenic global warming (CAGW) have greeted it as the final nail in the coffin of dissent. Why? Because it concludes—take a deep breath, now—that “Global warming is real.”
Jumping to Conclusions
At the Washington Post, for example, opinion writer Eugene Robinson states:
For the clueless or cynical diehards who deny global warming, it’s getting awfully cold out there.
The latest icy blast of reality comes from an eminent scientist whom the climate-change skeptics once lauded as one of their own. Richard Muller, a respected physicist at the University of California, Berkeley, used to dismiss alarmist climate research as being “polluted by political and activist frenzy.” Frustrated at what he considered shoddy science, Muller launched his own comprehensive study to set the record straight. Instead, the record set him straight….
[B]lowhards such as Perry, Cain and Bachmann, who, out of ignorance or perceived self-interest, are willing to play politics with the Earth’s future. (emphasis added)
The only thing more stunning and frightening than the idiocy of equating “global warming” with “CAGW” is the failure of so much not only of the public, and not only of the media, but especially of the scientific community—well, okay, the already committed, true-believer “scientific community”—to recognize (admit? expose?) the rhetorical sleight of hand.
I will put the point bluntly, if a little technically: BEST is a classic case of ignoratio elenchi, the logical fallacy of arguing for a point other than the one contended, and pretending that by arguing for the one one has answered the other. Other ways of putting ignoratio elenchiare “irrelevant conclusion” and “irrelevant thesis.”
The Real Debate
Here’s the situation. Thousands of brilliant scientists—physicists and chemists (atmospheric, solar, cosmic, and more specialists), geologists, meteorologists, climatologists, statisticians, economists, and more have been debating for about a quarter of a century whether the warming all agreed had occurred since the end of the Little Ice Age (roughly the mid-nineteenth century) was largely natural or largely manmade.
And then, voila! In the midst of all that debate, over all those different questions that, together, constitute the debate over CAGW, the vaunted University of California, Berkeley, Professor Richard A. Muller stands up and says, “Global warming is real. End of debate.”
And people—I’ll list them again: the public, the press, and the true-believer scientific community—take him seriously!
Nothing heretofore in the CAGW debate has been more discouraging to advocates of reason than this. Forget about all the flaws inherent in BEST’s methodology, flaws pointed out by a large number of CAGW skeptics. Forget about the fact that Muller announced BEST’s results before the papers issuing from it went through peer review—a strategy environmental journalists by now should recognize for the stunt it is.
Forget about those things. The most stunning and disheartening thing is the demonstration this gives of the widespread incapacity to recognize when someone has conveniently changed the subject and then proclaimed victory.
Ignoratio elenchi. Okay, so it’s a Latin term. Get over it. Comprehend it, make it a normal part of your vocabulary, and be on guard for it.
And if, despite knowing that BEST is simply irrelevant to the CAGW debate, you’re still interested in its detailed errors (warming is a hard thing to quantify), see critiques by–among others–Roger Pielke Sr., Anthony Watts (here and here), William Briggs (here and here), Douglas Keenan, Luboš Motl, and Richard Lindzen and David Douglass.
