'Gaia' Scientist Admits Mispredicting Rate of Climate Change

DesScorp writes "James Lovelock, the scientist that came up with the 'Gaia Theory' and a prominent herald of climate change, once predicted utter disaster for the planet from climate change, writing 'before this century is over billions of us will die and the few breeding pairs of people that survive will be in the Arctic where the climate remains tolerable.' Now Lovelock is walking back his rhetoric, admitting that he and other prominent global warming advocates were being alarmists. In a new interview with MSNBC he says: '"The problem is we don't know what the climate is doing. We thought we knew 20 years ago. That led to some alarmist books — mine included — because it looked clear-cut, but it hasn't happened," Lovelock said. "The climate is doing its usual tricks. There's nothing much really happening yet. We were supposed to be halfway toward a frying world now," he said. "The world has not warmed up very much since the millennium. Twelve years is a reasonable time it (the temperature) has stayed almost constant, whereas it should have been rising — carbon dioxide is rising, no question about that," he added.' Lovelock still believes the climate is changing, but at a much, much slower pace."

    Yes, but Lovelock is a nut; he was on the alarmist edge. Always was. The "Gaia" model is a cool thing to talk to the public about, but it's not real science.

    The mainstream climate scientists are not and have not been mispredicting the rate of climate change. If you look at the data from models from 1979 (the National Academy of Science study), or even the models from 1967 (the Manabe greenhouse-effect calculation)-- the actual data fits the model very nearly exactly.

    The lesson to take home is that denying climate change is wrong, but exaggerating it is also wrong. Pay attention to the real scientists, and try not to give the fringe too much credance. Look at the data.

      No Model Fits This Data.

      Sorry. Show me a model made between 1995 and 2010 that fits the observed data of the last decade.

      The calculation done in 1967 by Manabe and Wetherald-- it's summarized in any textbook about atmospheric science. This was the first numerical calculation of the global greenhouse effect; their calculated response value is still near the center of the consensus value used today. Send me your email address and I'll send you a jpeg comparing the model and the data.

      Not one single fits.

      Incorrect. In fact, all of them fit, but I like to sue the Manabe calculation because it has the longest run of comparison of theory to experiment. The National Academy of Sciences study of 1979.

      ....Of course now Lovelock is declared to be a nut, an extremist, on the alarmist edge. But before he was:

      [long list of completely irrelevant stuff]

      Not a single thing you list has anything whatsoever to do with climate science. Nothing.

      List one single paper in which he contributes significant work to climate science. There aren't any. He's a colorful popularizer, but he's a biologist, not a climate scientist.

      That's the whole problem-- people keep paying attention to popularizers and colorful characters and other people who have loud mouths. Ignore them. Pay attention to the actual science.

  2. Climatologists Agree by Anonymous Coward · · Score: 5, Informative

    This pretty much brings James Lovelock into agreement the mainstream science, where the consensus prediction is for anthropogenic warming of at most a few degrees Fahrenheit by the end of the century. And hey, that's exactly what you're supposed to do when confronted with actual data, isn't it?

    I'm still waiting for the deniers to do the same.

    How did this make the front page of Slashdot??? James Lovelock is not a Climate Scientist, he's and an independent scientist and environmentalist who is famous for the Gaia Hypothesis a half-scientific half-philosophical metaphor for understanding Earth's biosphere. There is no reason anyone should give this man any credibility when it comes to speaking on the subject of Climate Change projections.

    Do you know who is qualified to speak on this subject? James Hanson, and a 1981 paper he published in a peer-reviewed journal attempted to project the rise in temperatures over the next 30 years. Those projections still managed to underestimate the observed rise in temperatures by 30 percent and even the worst case scenario of those projections managed to underestimate the observed trend.

    So no. You are not vindicated. You have demonstrated that you have no understanding of how science works, elevating the opinion of someone speaking outside their realm of expertise over the peer-reviewed published research of an expert with over three decades working inside the subject of climate change.

    > Changing power sources is dismantling civilization?

    If there isn't anything to change to it is. And there currently isn't. Name one potential source that could replace fossil fuels and I'll show you a source the same greens are already trying to deem unacceptable. Lets review:

    1. Nuke. Do I even have to go there? Even if we perfect fusion the greens will still wet themselves over the notion of power from anything with the N word attached.

    2. Hydro. Disrupts Gaia. Harms fish reproduction and prevents 'healthy' rivers. And there is some point to their arguments. If nothing else our attempts at dams for flood control have certainly had a mixed record of success.

    3. Wind. Assume it could actually produce enough energy. (Work with me here.) NIMBY is already rampant, greens are up in arms because when you fill square mile after square mile with windmills birds die. Who would have thunk it?

    4. Solar. Makes sense as a source of off-grid energy but will never compete on a cost basis. And that is if you ignore the horrid ecological side effects of making the panels. And again, now that there are plans to actually cover over mile after mile of desert with the things the usual suspects are aghast.

    5. Geothermal. Causes earthquakes.

    6. Biofuels. Will cause widespread famine long before providing a noticable fraction of world energy production. Take the recycled plant waste, switchgrass on land unusable for more productive use but don't plan on it being anything but a boost. Not a primary source.

    And if I have left your pet alternative energy source off this list be assured that it won't work either. It is great for soaking up grant money, deploying on a small scale to give egoboo to celebs but the second someone things it can be produced at a profit the downside will become clear.

    I don't know where people get off thinking they can spend 5% of their income on food when throughout history it required practically 100% of their labor.

    This is because agricultural productivity was so much lower in the past. It's not that food is artificially cheap today – it's that food is much cheaper and easier to produce now due to advances in technology. Mechanization, chemical research (fertilizers) and more recently biotechnology have all dramatically increased how much food you can get out of an acre of land, and decreased how much labor you need to put in to get it. Just 100 years ago, farmers were about 31% of the workforce in the United States. Nearly one of three Americans was a farmer. Today it's one-tenth that and yet we are producing far more food than ever before.
