Engaging With Climate Skeptics

In the wake of the CRU "climategate" leak, reader Geoffrey.landis sends along a New York Times blog profile of Judith Curry, a climate scientist at Georgia Tech. "Curry — unlike many climate scientists — does not simply dismiss the arguments of 'climate skeptics,' but attempts to engage them in dialogue. She can, as well, be rather pointed in criticizing her colleagues, as in a post on the skeptic site climateaudit where she argues for greater transparency for climate data and calculations (mirrored here). In this post she makes a point that tribalism in science is the main culprit here —- that when scientists 'circle the wagons' to defend against what they perceive to be unfair (and unscientific) attacks, the result can be damaging to the actual science being defended. Is it still possible to conduct a dialogue, or is there no possible common ground?"

    Open-sourcing the Global Warming Debate:

    AGW true believers and "denialists" should be able to agree on this: the data get the last word, because without them theory is groundless. The only way for the CRU researchers to clear themselves of the imputation of serious error or fraud is full disclosure of the measurement techniques, the raw primary data sets, the code used to reduce them, and of their decisions during the process of interpretation. They should have nothing to hide; let them so demonstrate by hiding nothing.

    In short, if computer models are the primary tool in making all sorts of climate predictions, then let's have transparency in building the models and getting conclusions from them.

If you don't tow the party line, you are clearly in the pocket of the industry or a moron or whatever, worthy only of being shouted down and silenced.

    That sort of attitude is a large part of what leads to the polarization of the issue, and is precisely what it seems that this person is trying to work against. If you have the attitude that anyone who is skeptical of your theory at all is to be dismissed a priori, well then you aren't going to win many converts, are you?

    Also I should note that attitudes like this make many people like me extremely skeptical. Whenever people act in a manner that demands unquestioning support, when they simply shout down those that disagree and attempt to silence them, when they are secretive about their methods and data, when they appeal to a consensus, when they say debate is over, well that raises my bullshit alarm. The reason is that is precisely how con artists operate. They present you with what they say as absolute truth and shout down those who would dare question it. They want to present you with only their reality, because they are indeed full of shit and they don't want that to come out. As such they attack those that question them and try to silence them, because they want to deflect from the questions.

    Well, when you act like a con man, that really sets off warning bells for me. Why would you do that? Why would you simply try to shut down those that question you if you are so sure of your position? While it doesn't make you a con to do that, it sure as hell makes me suspicious you are one.

    So really, shit like that doesn't help. If you are going to dismiss anyone who is skeptical of your viewpoint out of hand, you accomplish nothing. You won't convert any of them, obviously since you just dismiss them, and you'll make others wonder what it is you are so worried about.

    Likewise, many of the anti-AGW would be willing to sacrifice hundreds of millions of poor people in geographically challenged areas if the only alternative was strict curbs on their lifestyle, but would prefer not to have to actually say it. So they'd deny the science rather than admit the underlying sentiment.

    I strongly suspect that among the voters, there's only a small minority for whom the science is the principal factor in determining the preferred policy.

    I work with this stuff. Every day. 40 (well more like 50-60) hours a week. It took years of study for me (and everyone else)
    just to get to the level where you can properly understand what it is, exactly, that I do. That's what being an expert at something entails.
    Now when I get into a dispute with someone, they typically have the same level of expertise. They know more or less everything I do. I know what they're saying, and they usually know what I'm saying.

    Now you bring into that situation some layperson with their religious reasons or ideological reasons or crank personality, who wants to dispute the results of my work. So they pore over it, and they simply don't understand it. (And ignorance breeds arrogance more often than humility, as Lincoln said) But they think they do. And then they formulate their criticism. Even if that criticism makes sense (often not), it's typically wrong at the most basic level. And that will practically always be the case - because there's virtually *nothing* in the way of criticism that a beginner would be able to think of that an expert hadn't thought about already. You're just not going to find a professor of physics having made a mistake of forgetting the first law of thermodynamics.

    Now I'm happy to defend my science against legitimate, good, criticism. But a scientific debate is *NOT* where anybody should be TEACHING anybody science. What kind of 'debate' is it if every answer amounts to "That's not what that word means, read a damn textbook." It's not the scientists who are being arrogant then. Hell, since when didn't scientists bend over backwards to educate the public? We write textbooks, and popular-scientific accounts. Research gets published in journals for everyone to see, etc. It's not like we're keeping it a big secret - The problem is that some people are simply unwilling to learn, yet arrogant enough to believe they should be entitled to 'debate' with me, and that I should be personally burdened with educating them in the name of 'open debate'!

    (Just to pick one out of the climate bag. How often haven't you seen someone say "Yeah but climate change is cyclical!" - What? As if _climate scientists_ didn't know that?! Refuting someone's research with arguments from an introductory textbook)

Most of the time when I read a paper on climate change I can immediately spot lots of methodological and deductive errors, and, conveniently, they always come out in favour of anthropogenic climate change. Some argue that science is just another religion. This isn't true. However, the sort of 'science' most climate scientists are doing nowadays may as well be a religion, basing conclusions on manifestly insufficient data, and inferring causation based on correlation alone. Right now the climate sceptics don't need to make straw men to argue against - the scientific community is making the straw men for them.

    Scientists shouldn't be arguing against sceptics - scientists should be the sceptics. Even ignoring faulty reasoning, many published scientific results are wrong (see this article). Scientists should be constantly questioning results to try to arrive at a refined, unbiased analysis of the facts - instead we have become defensive, treating every sceptical inquiry as an attack, and as a result, the research doesn't get the sort of scrutiny necessary to advance our understanding.
