Conscious Choice cover

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

A calculator beats IPCC supercomputer models in predicting climate

IPCC computer models vs observations

The uncertainty of science: A simple climate model [pdf], designed to run on a calculator and not relying on the premise that man-made carbon dioxide is causing global warming, appears more accurate at predicting the climate than the high-powered supercomputer models of the IPCC.

The current climate models fueling belief in manmade global warming do have fairly good “fit” to the data on which they were tested. However, the predictivity isn’t that great – see the recent warming “pause” or have a look at the figure above. They’re also hella complex, requiring thousands of hours of supercomputer computations.

Early this year, Christopher Monckton of Brenchley, Willie Soon of the Harvard-Smithsonian Center for Astrophysics, David Legates of the University of Delaware, and Matt Briggs, “Statistician to the Stars” and sometimes PJM contributor, published a paper in Science Bulletin (the Chinese equivalent of Science) entitled “Why models run hot: results from an irreducibly simple climate model”.

They took a different approach. Observing the issues with the current climate models, they constructed a very simple model working from first principles. “Irreducibly” here means “it can’t get simpler and reflect basic physics.” … This model is about one step advanced from a “back of the envelope” calculation, since it requires taking a natural logarithm as well as some multiplication, but it’s easily done with a scientific calculator — or even a slide rule.

But it models actual temperature observations better than the complex models. [emphasis in original]

The figure on the right is from the new Monckton paper, and shows the utter failure of every complex global-warming climate model to predict the global climate for the past 35 years. Whether this new very simple model is more accurate than these supercomputer models, however, remains to be seen, but their work definitely points out the uncertainty and failure of the present theories to explain the climate. They simply don’t do so, and thus are not a useful tool for gauging what we should do about the climate, if anything. As the writers of the simple model conclude,

The general-circulation models now face a crisis of credibility. Not one of them predicted a stasis of as long as 18 years 6 months in global temperatures. Indeed, it is often stated that periods [greater than] 15 years without warming are inconsistent with models’ predictions. For instance, [two IPCC papers] state: ‘‘The simulations rule out (at the 95 % level) zero trends for intervals of 15 year or more, suggesting that an observed absence of warming of this duration is needed to create a discrepancy with the expected present-day warming rate’’.

The models relied upon in [the IPCC reports] predicted twice as much warming from 1990 to 2014 as has been observed. All models predicted a warming rate in the crucial tropical mid-troposphere considerably in excess of observation. It is no longer credible to ignore these ever-widening discrepancies between prediction and observation. IPCC itself has recognized that, at least as far as medium-term prediction is concerned, the models have failed, raising the legitimate question whether the longer-term predictions may also have been exaggerated, perhaps as greatly as the medium-term predictions.

As I say over and over again, the science of climate is incredibly complex and uncertain. No one yet understands fully how the Earth’s climate functions, and anyone who claims they do is either an ignorant fool or an outright liar. Keep that in mind as this presidential election cycle unfolds and candidates are challenged by the mainstream press (made up mostly of ignorant fools and outright liars) to comment on man-made global warming.

    That’s all we need, a more accurate digital crystal ball. I wish they would leave the weather predicting to astrologers, gypsy card readers, Shaman and their bones, and retirees in rocking chairs.
    Now if their program could predict the stock market, they may have something…
    The truth about computer projections bears repeating. Computers are stupid.
    Here is my favorite example. A Volkswagen traveling past a new 30 mph speed limit sign with built-in camera. He is clocked at 31 mph on the first day. The next day recorded at 32 mph. On the third he was traveling 33 mph. Computer projections put the Volkswagen doing 133 mph in 100 days. The math is right, but the results are ridiculous.

  • It appears you did not read the post carefully. The point of this new simple model is not to predict the climate, but to illustrate the weakness of all the other models, and to emphasize their worthlessness.

    The article’s conclusion is correct: “increasing CO2 concentration is not a crisis.” It is clear that there is another (or many other) factor that is more influential than CO2 concentration and that the IPCC models do not properly account for this factor. Even if the factor is that the heat “hides” in the oceans, it is not accounted for, and the models do not properly predict whether we need to expend resources fixing CO2 or fixing another more influential problem. Or for that matter whether the next ice age — due any millennium, now — is about to start, as predicted circa 1970.

    Statistician Matt Briggs has another blog that I read. Among his topics is that correlation is not causation, and the article noted: “The current climate models fueling belief in manmade global warming do have fairly good “fit” to the data on which they were tested.” That “fit” is correlation, and I have to wonder if the data for the test were chosen so that it would fit a correlation test.

    Climatology seems to have forgotten this problem, so they declared their models to be relevant based upon correlation with past data sets (which have been modified, so do they still correlate?). However, as is noted, the predictions have failed spectacularly, yet the models are still being advertised by the IPCC as relevant.

    Everyone’s job is based upon predicting the future. Even the sandwich maker who made my lunch predicted that the ingredients and amounts she used would make me a happy customer. When these predictions fail, then the job was poorly done and better prediction techniques (or models) become required. For any job.

    Except, apparently, for climatology and IPCC jobs.
