    The dynamics of atmospheric CO2 is very difficult to analyze because of its role in the biosphere. Increases in CO2 stimulates growth in vegetation which results in a natural carbon sequestration mechanism. The effect of this is to slow the rate of increase in atmospheric CO2. However, the details of this process are poorly understood. This is primarily due to the fact that there are hundreds of thousands of species of flora each with its own unique response to the availability of carbon. Modeling this response array and factoring it into a global climate model is an enormous task. Models of the system tend to be mathematically chaotic in that even small changes in the input parameters result in wildly differing outcomes. Unfortunately, this opens the door to selection strategies that are based as much on ideology as on the scientific method. Humans have a natural desire to simplify the complex even if the results veer away from objective reality. The consequences of this is the illusion of understanding. The problem is that it is much easier to believe something than to understand it.

      There are many mechanisms that are not understood well enough, on their own and in conjunction with others, to make predictions. Whatever the relative importance of that one, a fundamental flaw in the modeling mentality is the belief that it doesn't matter, regardless of instabilities and the interactions at different scales. The result is a Rube Goldberg "model" with free parameters manipulated and 'tuned' with the claim to predict the future and which cannot even predict the past.

        This is one of the reasons static modeling is used so frequently. It's a lot easier and can sometimes provide a useful perspective. But the world is a very dynamic place and static models are of limited utility. The ecosphere is highly complex and modeling it with a tool that has only a tiny fraction of that complexity is bound to produce limited results.

          Why do you call it "static" modeling?

            A static model assumes that parameters will not change once the analysis process has begun. For example a static model of atmospheric CO2 does not take vegetation response of increase in atmospheric carbon into account so it leads to unrealistically high concentration predictions. A static model does not recognize vegetation response as providing a natural carbon sequestration mechanism.

              Static parameters ('fudge factors') is not synonymous with a static physical process. I don't know what they are doing with what you refer to as vegetation response, but in principle the parameters they adjust could weight entire non-linear, dynamic processes.

          Yes and if you add the complexity of the Sun's dynamic cycles that are known and the correlation to weather here on Earth. The model would be much more accurate. The fluctuations in the number of Sun spots , the dark coronal holes and the encompassing solar wind, plasma filaments, solar flares and CME's (Coronal mass ejection's).

          Cosmic rays entering the atmosphere assist in cloud formation at around 18,000 ft. More clouds means more rain and cooler from the albedo effect. Fewer clouds the opposite.

          The Earth's electromagnetic sphere's fluctuation
          also plays a role in how much cosmic rays enter.. When strong it deflects the cosmic rays better than when weakened.

    So first they got rid of the Medieval warm period so that they could claim it was the hottest in recorded history and not have to deal with those pesky historical facts.

    Then when the slope of the curve didn't match their predictions, they lowered the temperature in the early part of the 20th century to get the curve to slope up more.

    Now that people are making the case that their grand tax and wealth transfer scheme isn't enough to fix the climate so we should just spend the money on fixing any affects of whatever happens, they are moving the goal posts closer so that their preferred solution might actually work.

    Why is anyone still listening to them?

    My dangerous dino mind just imagined Al Gore squeezing his eyes shut, covering his ears and repeatedly screaming, "I can't hear you! I can't hear you! La-la-la! La-la-la!"

    It irritates me to continually hear about the "97%". That number of supposed scientific adherents is as bogus as the human-caused climate change fiction. The number came from a poll that was sent to roughly a thousand scientists who published peer reviewed papers about climate activity. Only 300 had published papers analyzing possible causes, and of those only 79 responded, with one not ready to blame it all on humans. So the authors of the poll extrapolated from the opinions of 79 to imply that 97% of all the 34,000 or so scientists with some form of connection with climate study support the notion that climate change is entirely due to human activity. BS!

      Hi DrZarkov99,
      This is the mentality for the use of 97% consensus from the Skeptical Science a mouth piece for the statists.

      "Expert consensus is a powerful thing. People know we don’t have the time or capacity to learn about everything, and so we frequently defer to the conclusions of experts. It’s why we visit doctors when we’re ill. The same is true of climate change: most people defer to the expert consensus of climate scientists. Crucially, as we note in our paper:

      Public perception of the scientific consensus has been found to be a gateway belief, affecting other climate beliefs and attitudes including policy support."

        The words of the former British PM Gladstone often echo in my mind: "There are lies, there are damned lies, and then there are statistics!" I often wish that the abject failure of the polls that depicted a Hillary blowout victory would engender healthy skepticism, but I fear we'll continue to see polluted polls (skewed populations, small samples, biased questions) waved around madly by the propaganda mills that claim to be legitimate media.

    It is interesting how this is spun in the Nature Geoscience paper. The official model predicts 1.5 deg C increase with a 615 gigaton of carbon emitted since 1870. That level of carbon would be reached in just 7 years from now and we should have the warming of 2100. But the earth is not warming that much, now with their model rather than 70 more gigaton of carbon we need ~200 more to reach that 1.5C . In other words they went "Oh s**t the model is not working and in 7 years we'll look like fools, we better get a new one now!" But since the effect of carbon emission is lower, to lower the warming to less than 1.5C we need to cut carbon emissions even more, because the earth is still warming at the same rate! Finding the real responsible of warming would be a better choice.

      It is not warming and they are fools much like Dr Stadtler.
      The only way they show the temps is with false data ,manipulated data . The temp stations placed on heat islands are well known. The 1998 hot planet coincided with an extremely active sun .
      The sun is in the begining of a Grand Solar Minimum.
      A new study blows the greenhouse theory out the window.
      The paper argues that concentrations of CO2 and other supposed “greenhouse gases” in the atmosphere have virtually no effect on the earth’s temperature.

    Seems it is atmospheric pressure that determines planet temperatures and not the make up of that atmosphere.
    The moon gets just as much and maybe even more sunlight than earth, yet it's 90 degrees C cooler than that of earth...why?...no atmosphere.

      Thanks Carl an excellent addition to this post.
      The science is sound and repeatable. I am thinking this is a paradigm shift.
      Michael Mann and others ignore a request to review the paper,, no surprise and I wouldn't value their opinion anyway.

    This whole global warming scientific hoax goes back so many years. From the day the meters were put in place to record so-called warming, their placement was set to skew the results to show it was hot, really hot - esp. if they are in enclose brick NYC courtyards or where yet plane emissions blast them. The whole thing was a control device, to get people to do what leaders wanted. Who let Gorby into US schools with his Green agenda and false ideas, all while still holding his Communist Party Car politicians and "educators". Who planned Earth Day to fall on Vald. Lenin's birthday, some one who wanted to laugh at the stupid US citizens. Even the UN says they no longer care if global warming is true, as long as people think it is, and they can control them. Climate change is even more ridiculous - climate has always changed, luckily. CO2 warriors were doing one thing - going along to assure continued grant money as a reward. They persisted in saying electric engines were a salvation, even though the carbon footprints of all those batteries, is worse than conventional. They have to know that thy power is not there to plug in millions of battery cars every night, they can barely meet the needs of everyday life now. Of course they know, but hope we don't so they can control us. Unlike AlGore, I actually took science in college, what a moron he is, except when he goes to the bank with his bogus carbon credit money. Why is manmade climate control, by multiple counties, like our two HAARP installaotins never discussed. Because it does not lead to control of the population, and they don't want us to know how much we are paying to manipulate the ionosphere and jet streams.

      Or is it. With these folks it must have been like a miner hitting a gold vein twenty years ago. I can't help but think the demand for man made causes of natural events or cycles , inflating the value of biased studies based on models that are clearly inaccurate was and is hard to resist for these "experts".

    Climate Change Predictions: What Went Wrong? http://mailchi.mp/thegwpf.org/climate...

      Thanks for the link! The cool temps this year have been noticed around the globe from your link...
      "In recent months global temperatures have plummeted by more than 0.6 degrees: just as happened 17 years ago after a similarly strong El Niño." Not only that, but despite doom-and-gloom prognostications by global warming's biased, bought-and-paid for "scientist" forecasters, ice in the Arctic and Greenland both grew this year.

      Recent revisions of climate data have all been in one direction: Older data have been revised to show cooler temperatures, more recent ones, warmer temperatures. Statistics would suggest that random errors would be not all in one direction.

      So it looks suspiciously like scientist-statisticians who are getting big fat checks from governments that have every interest in selling the idea of inevitable and disastrous global warming are, if you will, cooking the books…."
