Has Scientific American jumped the shark on climate change? That's the contention of Climate Progress blogger Joe Romm (10/26/10), who accuses the magazine of treating human-caused global climate change as an open question.

Romm points to an article by Michael Lemonick (11/10) about Judith Curry, a climate scientist whose critiques of the Intergovernmental Panel on Climate Change are often cited by non-climate scientists who (unlike Curry herself) deny that people are dangerously warming the Earth. The articles seems to leave the impression that the truth on climate change is somewhere in the middle:

Climate scientists feel embattled by a politically motivated witch hunt, and in that charged environment, what Curry has tried to do naturally feels like treason--especially since the skeptics have latched onto her as proof they have been right all along. But Curry and the skeptics have their own cause for grievance. They feel they have all been lumped together as crackpots, no matter how worthy their arguments.

So there are "worthy...arguments" against the idea that human alteration of the atmosphere is causing the planet to warm up? If so, Scientific American is sitting on the scientific scoop of the decade.

Perhaps worse, the article was accompanied by an online poll to determine, in Lemonick's words, whether Curry is "a heroic whistle-blower, speaking the truth when others can't or won't," or someone who has "gone off the scientific deep end, hurling baseless charges at a group of scientists who are doing their best to understand the complexities of Earth's climate." Among the specific questions the Web poll asks is,  "What is causing climate change?"

There's something strange about any kind of poll on questions of science, as if the laws of nature responded to public opinion. But the adjective often used alongside of Web polls--which record the opinions of a non-random selection of Web surfers--is "unscientific." So why is Scientific American using one to gauge opinion on climate questions?

Stranger still, the magazine's website also features an "Energy Poll" conducted "in association with" the Shell oil company. It's hard to say whether this is an ad disguised as content or content that is underwritten and influenced by a self-interested advertiser--but either way, Scientific American has a major ethical problem.  Simply taking money for science journalism from a company with a critical interest in denying science is inherently problematic--just as it's dubious for Nova, the closest equivalent to Scientific American on TV, to be dependent on funding from climate change deniers (FAIR Blog, 9/14/10).

Scientific American has a proud tradition, and signs that it's falling short on the most critical scientific issue of our time are distressing. I've been concerned about the magazine's take on climate since last year's article, "Another Century of Oil? Getting More From Current Reserves" (10/09), which discussed techniques for pumping ever more oil without ever mentioning climate change. It was written by oil company executive Leonardo Maugeri.

PBS's Nova is taking money from one of the biggest bankrollers of climate change denial--and,  surprise surprise, the resulting programming tells viewers not to worry about climate change.  But PBS's ombud doesn't see this as a conflict of interest--because Nova is a "consistently first-rate program," and he trusts it.

Nova's conflict of interest was highlighted out by Climate Progress blogger Joe Romm (9/7/10), who had previously caught the Smithsonian promoting strange climate science after getting a grant from oil billionaire David Koch (Climate Progress, 4/1/10). Koch, who's a major funder of propaganda rejecting the science of climate change, is also one of the main underwriters of the popular PBS science program Nova--which is in itself a case of strange bedfellows.  (Another major sponsor of Nova is ExxonMobil, the other top funder of science-denial in support of  oil industry profits.)

With the New Yorker's Jane Mayer (8/30/10) calling attention to the Koch family's political donations--and mentioning the fear that David Koch's contributions are affecting the Smithsonian's exhibits--people naturally paid more attention to the donor credit for David Koch on a recent Nova rerun (8/31/10) called "Becoming Human." What raised more than a few eyebrows was the program's enthusiasm for climate change as a  driver of human evolution--with a not-so-subtle suggestion that we should bear this in mind in our current era of rapidly shifting weather:

Narrator: It is a simple but revolutionary idea: Human evolution is nature's experiment with versatility. We're not adapted to any one environment or climate, but to many; we are creatures of climate change.

Geographer Mark Maslin: I think we should actually look to our proud ancestry and how we evolved in East Africa and say: "That's how we survived that. We can survive the future, because we are that creature, because we are that smart."

Note that Maslin is not actually a climate-change denier--he's really a strong advocate for immediate action to restrict carbon emissions--but Nova quotes him as though he takes the don't-worry-be-happy stance adopted by...well, people like David Koch. Why is that?

As usual, PBS insiders take the position that where you get your money from is absolutely irrelevant, once again rejecting the entire rationale for public broadcasting: "Nova, like all WGBH programs, maintains complete, independent editorial control of its content," Nova executive producer Paula Apsell told PBS ombud Michael Getler. Getler, for his part, declares that "one rarely knows when or how, if at all, influence works its way," and that "as a viewer of what strikes me and a lot of others as a consistently first-rate program, I trust Nova"--a hands-off stance that would seem to reject the entire rationale for having an ombud.

PBS's position echoes the Smithsonian's--David Koch is "very interested in the content, but completely hands off," museum director Cristián Samper told the New Yorker. And that's Koch's position as well; asked by Archeology magazine (2/17/09) if he was involved in the editorial content of Nova's evolutionary programming, he replied:  "No, I am not. I've been following the Nova series ever since it first came on the air. I'm a great admirer."

In that same interview, though, Koch describes a visit to Olduvai Gorge to inspect the Leakey digs, which he also bankrolls: "When I got there they had discovered a Hominin's bones. They left them in the earth, waiting for me to arrive. And then when I arrived, they let me pull them out of the ground, which was kind of fun."

Presumably the Leakeys let him extract those bones not because of his paleontological expertise, but because they knew it would make a major donor happy. Nova also knows that downplaying the dangers of climate change would make its major donors happy--and it aired a program that presented climate change as a positive force for good. If you want to believe that that's a coincidence--well, all you have to do is trust Nova.

Fans of Freakonomics economist Steven Levitt (and his journalistic partner, Stephen Dubner) might well have been surprised to hear about Climate Progress blogger Joe Romm's devastating debunking (10/12/09) of the climate change nonsense in the duo's new book, Superfreakonomics. Romm points out wacky assertions in the bestselling authors' sequel, like this passage they quote approvingly from former Microsoft executive Nathan Myhrvold:

The problem with solar cells is that they're black, because they are designed to absorb light from the sun. But only about 12 percent gets turned into electricity, and the rest is reradiated as heat--which contributed to global warming.

It's as if the premise of solar panels is that they don't absorb as much heat from the Sun as coal-burning plants, and Myhrvold has discovered that because they're black (actually, they're usually blue) this won't work. In reality, of course, the actual advantage of solar panels over coal-burning plants is that they don't burn coal.

That's a kooky thing to put in a book. But even worse is Levitt and Dubner's misrepresentation of actual climate scientist Ken Caldeira, of whom the authors say, "His research tells him that carbon dioxide is not the right villain in this fight" (against global warming). Caldeira actually calls for outlawing devices that release carbon into the atmosphere, saying: "I compare CO2 emissions to mugging little old ladies.... It is wrong to mug little old ladies and wrong to emit carbon dioxide to the atmosphere. The right target for both mugging little old ladies and carbon dioxide emissions is zero."

It's surprising that bestselling authors who have written regularly for the New York Times Magazine would get a story so ridiculously wrong--but maybe it shouldn't be. When the original Freakonomics came out, University of Michigan economist John DiNardo wrote a review (American Law and Economics Review, Fall/06) that pointed out that the book misrepresented a study that was cited as substantiation for one of Levitt's more controversial claims: that legalizing abortion led to lower crime rates. Citing a study by Cristian Pop-Eleches of children born after Romania banned abortion, Levitt and Dubner wrote:

Compared to Romanian children born just a year earlier, the cohort of children born after the abortion ban would do worse in every measurable way: they would test lower in school, they would have less success in the labor market, and they would also prove much more likely to become criminals.

But in the actual study cited by Freakonomics, Pop-Eleches wrote:

On average, children born in 1967 just after abortions became illegal display better educational and labor market achievements than children born just prior to the change. This outcome can be explained by a change in the composition of women having children: urban, educated women were more likely to have abortions prior to the policy change, so a higher proportion of children were born into urban, educated households.

DiNardo has pointed out (though he does not do so in the version published in the American Law and Economics Review) that Pop-Eleches found that if you correct for demographic characteristics, children born after the abortion ban did less well than those born before, but this is very different from saying that the cohort did worse; DiNardo noted (quoting Pop-Eleches) that the study indicated that "the positive effect due to changes in the composition of mothers having children more than outweighs all the other negative effects that such a restriction might have had."

Levitt actually responded to diNardo's criticism in a snide blog post (Freakonomics blog, 2/6/08), which quoted Freakonomics' claim about the cohort doing worse, quoted Pop-Eleches' finding about outcomes after "controlling for...observable background variables," then deceptively concluded, "Sounds to me like Freakonomics and Pop-Eleches are saying the same thing"--ignoring the part where Pop-Eleches found that the cohort actually did better, thus giving readers no clue as to what DiNardo's actual complaint about Levitt's use of the paper was. ("C'mon, John, you're a top economist, and our book is 300 pages long. You must have better criticisms than that!" Levitt snarked. Well, yeah--most criticism sounds better when you actually explain it.)

This dishonest response to criticism foreshadowed Levitt's similarly slippery response (Freakonomics blog, 10/17/09) to Joe Romm's critique--see Climate Progress, 10/17/09. Maybe the climate change chapter from Superfreakonomics isn't an aberration--maybe people are just catching on to Levitt's smartest-guy-in-the-room act.
