Fifty To One

A new climate education project:

50 to 1 cuts across all the noise and fury surrounding the ‘climate debate’ and gets right to the point: Even if the IPCC is right, and even if climate change IS happening and it IS caused by man, we are STILL better off adapting to it as it happens than we are trying to ‘stop’ it. ‘Action’ is 50 times more expensive than ‘adaptation’, and that’s a conclusion which is derived directly from the IPCC’s own predictions and formulae!

Here’s a link to the Indiegogo site.

Fraud In The Social Sciences

Megan McArdle has an excellent piece on the nature of the discipline and its perverse incentives:

The system was rewarding a very, very specific thing: novel but intuitively plausible results that told neat stories about human behavior. Stars in that field are people who consistently identify, and then prove, interesting but believable results.

The problem is that reality is usually pretty messy, especially in social psychology, where you tend to be looking for fairly subtle effects. Even a genius will be wrong a lot of the time: he will invest in hypotheses that sound convincing but aren’t actually true, or come up with data that is too messy to tell you much one way or another. Sadly, the prestige journals aren’t looking to publish “We tested this interesting hypothesis, and boy, the data are just a mess!” They want a story, the clearer, the better.

Academics these days operate under enormous pressure to churn out high volumes of these publications. Hitting those targets again and again is the key to tenure, the full professorship, hopefully the lucrative lectures. Competition is fierce for all of those things, and it’s easy to get knocked out at every step. If getting good results is somewhat random, then all those professors are very vulnerable to a string of bad luck. The temptation to make your own luck is thus very high.

Again, I do not excuse those who resort to cheating. But as the consumer of these publications, we should be worried, because this system essentially selects for bad data handling. The more you manipulate your data (and there are lots of ways to massage your data so that it shows what you’d like, even without knowing you’re doing it), the more likely you are to come up with a publishable result. Peer review acts as something of a check on this, of course. But your peers don’t know if, for example, you decided to report only the one time your experiment worked, instead of the seven times it didn’t.

It would be much better if we rewarded replication: if journals were filled not only with papers describing novel effects, but also with papers by researchers who replicated someone else’s novel effects. But replicating an effect that someone else has found has nowhere near the prestige–or the publication value–of something entirely new. Which means, of course, that it’s relatively easy to make up numbers and be sure that no one else will try to check.

Most cases are not as extreme as Stapel. But if we reward only those who generate interesting results, rather than interesting hypotheses, we are asking for trouble. It is hard to fake good questions, but if the good questions must also have good answers . . . well, good answers are easy. And it seems that this is what the social psychology profession is rewarding.

Emphasis mine.

What I found fascinating about this is that you can substitute the phrase “climate science” for “social psychology” and (say) “Mann” for “Stapel,” and it makes just as much sense.

This is probably worth a PJMedia piece.

One other phrase that would have to change: “that told neatpolitically appealing stories about human behaviorhumanity’s impact on the environment.”

The Bee Mystery

I hadn’t known about this:

Researchers are making headway in mapping the genes that help bees overcome these obstacles, including which genes help them safely break down pesticides. Now researchers have identified several compounds that help turn on those genes. They’re present in honey, something commercial bees don’t get to keep–their food supply is taken for human use, and bees are feed sweet substitutes like corn syrup.

Wenfu Mao and colleagues found three compounds in honey that increase the expression of a gene that helps bees metabolize pesticides. The most important chemical is something called p-coumaric acid, which is found in pollen cells. By eating honey, which contains pollen, the bees are exposed to a compound that basically boosts their ability to break down dangerous chemicals. So honey substitutes like high-fructose corn syrup may compromise their health.

You don’t say. Corn syrup isn’t good for anyone. No reason to think it would keep a bee healthy, but apparently the industry fooled themselves into thinking so.

Now that they understand this, maybe there’s something they can do about it, and still harvest honey.

Jamestown

We’d always known that it was rough there early on, but they’ve actually found solid evidence of cannibalism:

The researchers used this reconstruction, along with the other data, to determine the specimen was a female, roughly 14 years old (based on the development of her molars) and of British ancestry. Owsley says the cut marks on the jaw, face and forehead of the skull, along with those on the shinbone, are telltale signs of cannibalism. “The clear intent was to remove the facial tissue and the brain for consumption. These people were in dire circumstances. So any flesh that was available would have been used,” says Owsley. “The person that was doing this was not experienced and did not know how to butcher an animal. Instead, we see hesitancy, trial, tentativeness and a total lack of experience.”

As I discuss in the book (though I don’t mention this, and it’s probably not worth adding it at this point), the settlers were not well chosen, in terms of skill sets for settling. The only really useful skills most of them had were in fighting, not farming or homesteading.

I have to say, the one time that I visited the island, maybe twenty years ago, there were deer on it in rodent-like abundance. I guess they weren’t as plentiful back then. And of course, by then, it was a national historical park, and they were protected.

The Green EU

It took an economic disaster for them to reduce their carbon output:

But the data shows that even though EU economic weakness and US natural gas are responsible for significant drops in emissions in the developed world, developing countries, led by China, continue to drive the global total higher.

This underscores the disconnect between green policies and green results. The US hasn’t checked off many items on the green wish list for domestic legislation; Europe has. But it turns out that the introduction of the euro and the subsequent economic disaster had more to do with European emissions drops than Kyoto or the shambolic carbon-trading program.

The usual suspects are headed to Bonn next week for another forlorn attempt to carve out a meaningful global climate treaty. Meanwhile in the real world, the challenge is to find a way for developing countries to continue rapid growth without driving greenhouse gasses and other pollutants to potentially dangerous levels.

That’s assuming that the high levels of the “other” “pollutants” is more dangerous than slow economic growth, of course. And meanwhile, it turns out that the US has twice as much oil, and three times as much gas as we thought. And “peak oil” continues to recede into the future, to the tears of the Malthusians. Which are delicious.

[Update a while later]

Gazprom (and the Russian economy) are in trouble, too:

The US has begun exporting gas to Europe, and has also ramped up coal exports by more than 250 percent since 2005. The net result has been to knock Gazprom back on its heels. The WSJ reports that the negotiations with Bulgaria were heated, with Gazprom’s negotiators shouting in frustration on several occasions.

In public statements, however, the Russian company remains defiant (and perhaps in a state of denial) about the implications of the shale gas boom…

Well, that’s one tactic, I guess. Not one I’d recommend, though.

The Paradox Of Consensus

This is the essay I’ve been meaning to write, but not taken the time. Fortunately, someone else did:

Consensus, in and of itself, is not necessarily a bad thing. The more easily testable and verifiable a theory, the less debate we would expect. There is little disagreement, for example, about the sum of one plus one or the average distance of the earth from the sun. But as a question becomes more complex and less testable, we would expect an increasing level of disagreement and a lessening of the consensus—think: the existence of god, the best band since the Beatles, or the grand unified theory of physics. On such topics, independent minds can—and should—differ.

We can use a simple formula to express how an idea’s popularity correlates with its verifiability. Let us introduce the K/C ratio—the ratio of “knowability,” a broad term loosely encapsulating how possible it is to reduce uncertainty about an idea’s correctness, to “consensus,” a measure of the idea’s popularity and general acceptance. Topics that are easily knowable (K ~ 1) should have a high degree of consensus (C ~ 1), whereas those that are impossible to verify (K ~ 0) should have a low degree of consensus (C ~ 0). When the ratio deviates too far from the perfect ratio of 1, either from too much consensus or too little, there is a mispricing of knowledge. Indeed, in cases of extreme deviations from the perfect ratio, additional support for a concept with such a lopsided K/C ratio increasingly subtracts from its potential veracity. This occurs because ideas exist not simply at a single temporal point, but rather evolve over the sweep of time. At the upper reaches of consensus, there is less updating of views to account for new information—so much so that supporters of the status quo tend to suppress new facts and hypothesis. Government agencies deny funding to ‘sham’ scientists, tenure boards dissuade young researchers from pursuing ‘the wrong’ track, and the establishment quashes heretical ideas.

…To see how this works in practice, we turn to the evergreen topic of climate change. Notwithstanding the underlying ecological threat of climate change itself, the debate about how to confront human-caused global warming has spawned unprecedented financial, political, and social risks of its own. Entire industries face extinction as the world’s governments seek to impose trillions of dollars of taxes on carbon emissions. The New York Times’s Thomas Friedman approvingly writes that Australian politicians—not to mention public figures through the world—now risk “political suicide” if they deny climate change. But if carbon dioxide turns out not to be the boogey-man that climate scientists have made it out to be, tens of trillions will be wasted in unneeded remediation. Much of the world—billions of humans—will endure a severely diminished quality of life with nothing to show for it. The growth trajectory of the world in the twenty-first century may well depend more on the “truth” of climate change ex ante than ex post.

With climate change, as in many areas of scientific complexity, we can (and do) use models to understand the world. But models have their problems. This is particularly true when dealing with complex, non-linear systems with a multitude of recursive feedback loops, in which small variations produce massive shifts in the long-term outcome. Pioneered by the mathematicians Edward Lorenz and Benoit Mandelbrot, chaos theory helped explain the intractability of certain problems. Readers of pop science will be familiar with the term the “butterfly effect,” in which “the flap of a butterfly’s wings in Brazil set[s] off a tornado in Texas.” The earth’s climate is one such dynamic, chaotic system and it is within the whirling, turbulent vortex of unpredictability that the modern climate scientists must tread.

And boldly have they stepped into the breach. The scope of agreement achieved by the world’s climate scientists is breathtaking. To first approximation, around 97% agree that human activity, particularly carbon dioxide emissions, causes global warming. So impressed was the Norwegian Nobel Committee by the work of the Inter-governmental Committee on Climate Change and Al Gore “for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change” that it awarded them the 2007 Nobel Peace Prize. So many great minds cannot possibly be wrong, right?

Wrong.

Global Warming Theory

…is the new Lysenkoism:

All the climate alarmist organizations simply rubber stamp the irregular Assessment Reports of the United Nations Intergovernmental Panel on Climate Change (IPCC). None of them do any original science on the theory of anthropogenic catastrophic global warming. But the United Nations is a proven, corrupt, power grabbing institution. The science of their Assessment Reports has been thoroughly rebutted by the hundreds of pages of science in Climate Change Reconsidered, and Climate Change Reconsidered: 2011 Interim Report, both written by dozens of scientists with the Nongovernmental International Panel on Climate Change, and published by the Heartland Institute, the international headquarters of the skeptics of the theory of anthropogenic catastrophic global warming.

Again, check it out for yourself. You don’t have to read every one of the well over a thousand pages of careful science in both volumes to see at least that there is a real scientific debate.

The editors of the once respected journals of Science and Nature have abandoned science for Lysenkoism on this issue as well. They have become as political as the editorial pages of the New York Times. They claim their published papers are peer reviewed, but those reviews are conducted on the friends and family plan when it comes to the subject of anthropogenic catastrophic global warming. There can be no peer review at all when authors refuse to release their data and computer codes for public inspection and attempted reconstruction of reported results by other scientists. They have been forced to backtrack on recent publications relying on novel, dubious, statistical methodologies not in accordance with established methodologies of complex statistical analysis.

Formerly respected scientific bodies in the U.S. and other western countries have been commandeered by political activist Lysenkoists seizing leadership positions. They then proceed with politically correct pronouncements on the issue of anthropogenic catastrophic global warming heedless of the views of the membership of actual scientists. Most of what you see and hear from alarmists regarding global warming can be most accurately described as play acting on the meme of settled science. The above noted publications demonstrate beyond the point where reasonable people can differ that no actual scientist can claim that the science of anthropogenic catastrophic global warming has been settled or that there is a settled “consensus” that rules out reasonable dissent.

My emphasis.

Climate “science” doesn’t seem to have very many actual scientists involved with it.
