Does Gaia Like It Hot?

    Though not my area of expertise, I have an observation: how right or wrong have predictors been and what are scientists really agreed upon given complexity of climate forecasting.
    Equally, “it is one thing to be alert to uncertainty and another to actually estimate it properly…. Although climatologist might think carefully about uncertainty, there is uncertainty about how much uncertainty there is.”

    Given that, “Earth’s surface temperatures have defied the predictions of climate models for the past decade, coming in considerably cooler than expected” is it perhaps time to stop referring to climate alarmists as climate “scientists”? Science is about proving hypotheses, and the AGW hypotheses have uniformly failed the test.

    Furthermore, given that Earth’s temperature has actually declined (albeit slightly) since peaking in late 1996, should we not acknowledge the fact, rather than fudging with, “cooler than expected.” In terms of the climate change debate, there’s a huge difference between “not rising as much as expected” and declining.

      Temperatures have been trending downward since the late 90s. But there’s no average temperature of the Earth — this is a meaningless concept. Nor is heat a “thing” that can be “trapped.”

      Indeed, no one has a good definition of climate, so we don’t even know what we’re talking about. Certainly, the atmosphere-ocean system is chaotic and has no long-term average. A more subtle and robust definition is needed, so we can talk sensibly about what’s “changing.”

    AGW isn’t about science. It’s about how much money can be taxed out of Rich nation into the pocket of NGO and third world countries. It doesn’t matter if it’s getting warmer or colder, so as long as they can identify the cause of Western evil, they can fix it with tax.

      It’s all about grabbing control, of many things: the economy, politics, intellectual and scientific culture, etc., etc.

  • Nick Bidler

    It’s almost as though a poorly-understood branch of science is being used as a catch-all for pushing greater government control of public life.

    Coincidentally, many of the people who think global warming is a pressing issue would prefer greater government control of public life anyway.

    Something something, I’m not cynical enough.

      No, you’re not 🙂

      It’s the great substitute religion of our time, now that socialism is dead.

    “Earth’s surface temperatures have defied the predictions of climate models”
    Easy to do when bad data is fed in to faulty models. Models that can’t predict known, observed events are worthless.

    • Kavanna

      It’s worse than that. This year’s climate models are updated with last year’s data, to “predict” next year’s climate. But that’s essentially cheating, and such models are not predicting anything. They’re retroactively updated with the right answer.

      If such corrections were NOT applied, the resulting original/unchanged models from the 1980s and 90s would be way off in everything: temperatures, rainfall, storms, whatever.

      The situation with climate models is much worse than most people realize. The climate modeling establishment has avoiding discussing this fact, to keep the money coming.

        Climate hysteria has always been about two related things: money and power (literal and figurative). The Greens for the most part have consisted of unregenerate and unapologetic Marxists/Utopians who were bereft of their ideal state when the Soviet Union collapsed. If they could gain control of energy policy, they would become the de facto rulers of the economies and money and more political power would flow to them. That goes for the bearded professorial munchkins laboring feverishly in laboratories to cook up data to feed into models that were preprogrammed to give them the answer they needed to unleash even more money for their projects. It wouldn’t bother me at all if they all disappeared tomorrow. They’ve so badly damaged the reputation of science as the last pristine, politics-free field of expertise that it may be another 200 years before science recovers.
