A Skeptical Look at Global Warming

Despite living in California, I only have a basic, mainstream understanding of global warming. My knowledge is more or less limited to what I learned in high school earth science, casual conversations with friends (generally those of the green persuasian), and what I’ve read in the newspapers, magazines, etc.

A few people I know (both locally & in the blogsphere), have mentioned they really liked Al Gore’s An Inconvient Truth, and thought it did a great job explaining global warming & the dangers it presented.

I thought it would be an interesting excerise to write down my thoughts & opinions prior to seeing the film, and then seeing how, if at all, they changed afterwards.

So, before seeing it, here are my biases. Note that some of these could be (and probably are) wrong. Again, they’re not really backed by fact — they’re more or less vague impressions at best.

  • Al Gore is a jackass.

    His 1988 run for the presidential nomination (against Jesse Jackson) showed he’s something of racist, he’s not very charismatic, and people around him have describe him as not very intelligent. In short, he seems to be the Democratic response to George Bush.

    Harboring a mild dislike of Bush, I’m not inclined to like Gore much either.

    Still, that doesn’t mean whatever Gore says is automatically wrong. As Robert Pirsig said, “Just because a fool says it’s raining outside, doesn’t mean that it isn’t”, so I’ll try to keep an open mind to what is being said and less who is saying it.

  • The discussion on global warming is filled with ulterior motives.

    Obviously, it wouldn’t surprise me if a Exxon sponsored a study that showed global warming wasn’t happening. Same for car manufactures, coal mines, or any other enterprise which currently profits and in some way contributes to pumping CO2 into the atmosphere.

    But that doesn’t mean that they’re alone. If Ralph Nader came out with a study showing global warming is happening, I wouldn’t be surprised either, as he’s not going to get elected if people think it’s not a big deal.

    Likewse, if you hate Bush, Republicans, Big Business, Capitalism, the American Way of life, and you believe global warming runs counter to any of them, there’s incentive to find yourself supporting global warming.

    There’s two other additional motivations that aren’t tied to personal gain: 1) There’s something in people that tends to attract them to the idea they’re living in the end times. It doesn’t matter if it’s people reading Left Behind, screaming we’ll all going to die in a nuclear holocaust, a Branch Davidian, or we’re going to die of global warming. Some people are attracted to the ideas regardless of the evidence behind them.

    2) People like to feel they’re part of an elite group. What defines the creed of that elite group can vary — it could be a belief in God (a la those trying to ban gay marriage or flying planes into buildings), it could be a belief in a race (a la the Nazis), or it could be how you treat the environment (a la Greenpeace & Ralph Nader).

  • The science of global warming is heavily politicized.

    One thing I like about science over politics, is that while politics attempts to hide facts that don’t support an idea, science dictates that they be brought forward. It isn’t uncommon to hear about evidence that doesn’t support a prevailing theory. You readily hear from most scientists about how there is a inherent contradiction between quantum mechanics & the theory of relativity. When Andrew Wiles’ first iteration of his proof of Fermat’s Last Theorm was found to contain a flaw, Wiles didn’t simply dismiss them as someone who didn’t want to believe in the theorem. However, this does seem to happen with global warming.

    To hear those advocating its existence, the science behind global warming has long been overwhelming and proven without a shadow of the doubt.

    In the Economist a few months back, an article ran where one of the final global warming pieces of the puzzle had fallen into place. In a nutshell, since the 70s, data from weather balloons & satellites have indicated that the temperature of the troposphere has been stable. This was particularly confusing to climatologists, as global warming theory would indicate its temperature should increase in conjunction with the Earth’s surface temperature, but that was not the case.

    The final piece of the puzzle was how this could be, but the first question in my head was why is this the first time it’s being mentioned. A fair & open discussion about a theory is going to include evidence in support and against it, yet this was hardly mentioned until it could be dismissed and, even with the hole, the theory had been called rock solid.

  • The Earth is very old and goes through cyclical temperature changes.

    Most of what I’ve read seems to look at a very, very narrow time period compared to the age of the earth. It also seems to ignore or not address how it fits in with other periods of cooling & warming the Earth has gone through in the past, both with man & without.

    This could, however, simply be a limitation of what I’ve been exposed to. I had dinner with a friend bit back, just after he had finished his first year of grad school in atmospheric sciences. He mentioned some interesting facts on how they could look at historical temperature and carbon levels with ice cores (and showed an exponential upswing in the CO2 levels in the last 50 years or so), but didn’t know much as to any environmental theory behind temperature swings on the order of the ice ages. Again, it doesn’t mean it’s not there, just I’m not aware of it.

  • The scientific method requires repeatability.

    In a letter to the editor of my alumni magazine, a group biologist responded to an article about Intelligent Design, declaring it couldn’t be called science because it lacked several aspects of traditional established scientific practices, notably repeatability. That is, there is no experiment you could give asserting intelligent design that someone else could do to assert the theory is correct.

    Weather is an incredibly complex, chaotic system. (Think of this, with all our technology, we can’t say for certain if it’s going to rain even a month from today or not.) It seems very challenging, if not impossible, to put forth a theory on global warming that others would be able to independently execute and validate. After all, we’ve only got one Earth.

  • I’m Conservative

    Others may think this will skew thing a great deal, but I doubt much, if any, impact. After all, Teddy Roosevelt was both a conservative and a conservationist.

    Despite all that, however, probably my biggest bias is:

  • Global warming probably does happen and it probably is caused by man.

    I lean towards thinking global warming is happening & it’s due to pollution from mankind. Asked to prove it, or convince someone else, I doubt I could. My reasons are shaky at best.

    So why am I leaning that way? A few reasons, none of them terribly scientific:

    • Most people I know seem to believe it.
    • It jives up with what I learned in high school & greenhouse gases.
    • People I know personally, respect & who are better educated on the matter, believe it. That really boils down to a handful of people: the previously mentioned buddy in grad school, and Brandon, or more directly, Brandon’s dad, who’s worked with the environment for the federal government his whole life.

    And with that, I’m off to see the movie. I’ll post my impressions afterwards, in the mean time, if you have any links that you think would be good to read afters — either for or against global warming — feel free to post them below. I’ll try to read whatever people send my way & post my impression. (Brandon’s already given me a half dozen or so. :-)

      I am very interested in what you think after seeing the movie. I’ve also got lots of good ideas for you if you are feeling skeptical about climate change, but if you check out illconsidered.blogspot.com you’ll get the best info.

      no need to abandon the free-market and establish a socialist society run by eco-nazis yet!

    5. ben Says:

      People who don’t believe in climate change are funny.

      They’re always like, look we didn’t cause it. That’s just not possible. Also it doesn’t exist. It’s going to be 105 instead 103 this summer, boo hoo you eco-freaks. All Al Gore wants to do is ruin the economy. I’ll bet!

    6. ben Says:

      The other thing I hate is fucking name calling. What is the deal with the wingnut eco-freak nazi bullshit? It makes some the name callers sound so stupid and childish. And people like Ann Coulter and Michelle Malkin can’t even hear what they’re saying. They complain that liberal people are the ones undermining the debate…

    7. futuregeek Says:

      If you’re going to get info from Stewie Milloy over at Junkscience.com, you might want to know a little bit about him. There are some good links collected here:

    8. futuregeek Says:

      A quote from one of the links:

      “Milloy says that “the hysteria about global warming is entirely junk science-based” and that he sees no need to disclose the ExxonMobil funding in his writing because it’s not “relevant.”"

      :-D

    9. scott Says:

      So rather than showing that his information is incorrect, you attack his funding? Seems like truth should be truth no matter who is supporting the speaker…

    10. futuregeek Says:

      It’s definitely something you should keep in mind.

      You might also find it interesting to look at the strangely coincidental way his attacks on ‘junkscience’ line up with rightwing political causes…. Curiouser and curiouser, no?

    11. Scott Says:

      The same could be said for Gore, Curious how his attacks line up with extremist left-wing group agendas….

      Curiouser and curiouser, no?

      Forget the supporters….look at the science

      I love the progression from “There’s no such thing as global warming” to “yeah, there’s climate change, but humans aren’t causing it.” Next year, it’ll be “yeah, we’re causing it, but there’s no way to reverse it.” The following year, it’ll be “Yeah, we could fix it, but it’s all the fault of the Chinese, so they should change, not us.” A decade from now, the same people will be insisting they were at the forefront of the fight against anthropogenic climate change, and if only everyone had listened to them, we wouldn’t be having all these disasters.
