Ice Age At 2000+ PPM CO2

Climate during the Carboniferous Period

Earth experienced an ice age 450 million years ago, with CO2 somewhere between 2000 and 8000 ppm. According to Hansen’s theories – all life on Earth should have been extinct before it even evolved.

    Wikipedia does not have a page for the Ordovician ice age. Wikipeadia claims the Ordovician Ige age was only 0.5-1.5 million years long. The thickness of the blue temperature line is about 4 million years. Clearly they’re in deep denial.

  2. pet says:

    do you mean 2000-8000 PPM?

  3. kirkmyers says:

    For obvious reasons, the Warmists never talk about the cold of the Late Ordovician Period, when the planet’s average temperature was far lower than today’s 15 degrees centigrade, yet CO2 concentrations were nearly 12 times higher, at 4,400 ppm. According to the conventional greenhouse gas theory, our planet should have overheated. There are clearly other influences (the sun comes to mind) besides CO2 that impact the earth’s global temperature.

    But if you’re a scientist trolling for research dollars to study (“confirm” is a better word) human-caused “climate change,” such facts are inconvenient. And those skeptics who cite such data our attacked and ridiculed for challenging the “scientific consensus,” which, of course, is non-existent.

  4. kirkmyers says:

    There is a treasure trove of excellent research at this site that exposes the CO2 warming myth.

  5. Andy DC says:

    According to peer review from 97% of leading climate experts, the earth should have heated up above the boiling point and all life should have been exterminated. The fact that it did the opposite would appear to undermine their already highly dubious credibility.

  6. Cthruit says:

    Finnaly we know the truth… CO2 causes cooling and to stop future out-of-control global cooling we must control CO2 output. Our food supply depends on it! CO2 continues to increase with no associated increase in warming. The science is so complex that warming can cause cooling or what is called “wooling”, which is bad. All funding must be diverted to study AGC. If CO2 doesn’t cause warming then it must cause something, Right?

    It was “Celestial driver of Phanerozoic climate?” by Shaviv & Veizer (2003) that helped kick me from Lukewarmer to skeptic to scoffer in 2007 when I first read it, thanks to Svensmark’s Cosmoclimatology paper which referenced it and other very interesting lines of investigation. And that path has been steadily been solidified with both theory and experiment thanks to the likes of Svensmark, Friis-Christensen, Shaviv, Veizer, Lindzen, and not the least Kirkby. And a host of others.

    From Shaviv’s website:

    Figure 5 is from SV03, which can be found here:

    Figure 1 from SV03 shows the poor correlation between CO2 and ocean temps over the past ~500 million years.

    Palaeontologists are also in denial about the atmosphere as according to everything we think we know the dinosaurs could not have existed in the thin atmosphere we have at present let alone some have flown. Its only when we join up the thinking as good engineers have been trained to do that we can make use of the information scientists provide us with. They on the other hand are on the whole poor at thinking things through if it involves knowledge outside their field of expertise which these days can be very narrow

    only die hard climate denier losers read this crap anyways – good thing nobody that matters takes this blog seriously

  10. for one brief period of about 10M years, out of 1/2 billion years or
    about 2% of the time, available information indicates that the CO2 was high and the temperature was low. Well, we know where the really stupid money will bet don’t we?

    How stupid you ask: Well dumber than trees, and almost everything that flies, creeps or swims:

    Given an organism in an environment one can state that the most adaptive will, by definition, be the most likely to survive. In order to adapt to an environment, an organism must understand it. One could say that the ability to understand ones environment is perhaps the best measure of intelligence that exists. As far as evolution is concerned it is the only measure that counts. Being able to do math and calculate a trajectory does not count, but being able to dodge a predator definitely does count. If two organisms share about the same abilities to react to a given situation then the organism that can read the situation the most accurately is the one most likely to survive.

    Now consider Global warming. A search of the internet will quickly demonstrate that the vast majority of species on the planet are moving to the poles, or are moving, if they can, to higher elevations. In addition to that, the timing of migration patterns are changing. If this data is not accurate then not only are all climate scientists part of this climate gate conspiracy, but so are all botanists, ethologists, marine biologists, and microbiologists, entomologists and probably some others. So there is the first bit of information: If you do not believe that the climate is warming on a global scale then in terms of evolution you are less knowledgeable about your environment (less intelligent) then the great majority of animals, plants, insects, and even ocean dwelling single celled organisms like plankton. Yep, you are dumber than a plant or an insect.

    The pattern of GW denial sort of follows that of, and is similar to the arguments used to deny the correlation between smoking and cancer and a host of other diseases. You had actual scientists looking at the best available evidence on one side, and then you had paid charlatans with degrees in science working for corporations whose interests were threatened on the other. That was not 100% mind you, but it was pretty much how the advocates of the two positions lined up. A prime example is Dr. Frederick Seitz who sold out to become a spokesman for big tobacco and tried to convince people that tobacco was harmless. Later, after, at least according to many who were close to him, he became senile, he sold out to climate deniers.

    Now in this case on one side we have not only actual scientists doing their best to explain available information in light of best understood implications of thermodynamics, quantum mechanics, black body radiation etc. but you have almost all other life forms on the planet. By other forms of life, I mean almost every entity on the planet living in all but the most extreme areas.

    Now if we accept GW, the next question is: what causes it? Trust me, it is not the sun which for the past 50 years has remained fairly constant or produced less radiation over that time while temperatures have risen. It has not changed much in the past 2000 years. Neither has known cosmic ray counts. This leaves galactic unicorn farts and CO2. We know about CO2, and how it would work, and the most likely results. We have no evidence of unicorn farts, but we do know about bloviation sources from hot air producers.

    Another red herring from AGW people are the failure of computer models and the testability of theories. If the prediction of a theory fails then the theory is false. Well folks, then I guess that the germ theory of disease is false. Clearly, many people exposed to “so called germs” never get sick. On the other hand people get sick who have never been exposed to these “so called germs” But wait, they are not really germs, they are viruses. See — those scientists keep changing their story. Because they are in the pay of big pharma who just want to sell us drugs to make us sick so that they can make us more sick. And space that is another hoax. You know that the sun goes around the earth, just go outside and look for yourself. What? You believe the so called scientists?

    And speaking of hot air producers. This is a standard equation in statistics, the Gaussian integral. If you can not follow the proof, then you do not have a basic understanding of one of the most basic equations in statistics, which means that you do not understand statistics, which means that you are as competent to argue a point of view on AGW as you are to advocate competing forms of cancer treatment without ever having had a course in biology.

    Another measure of the incompetence of an AGW deiner is that I doubt that one in a hundred would be aware that there is a difference between random and chaotic, and I doubt that one in 1000 would know the difference, or understand it if it were explained to them. Again: few in the AGW camp know any math beyond advanced algebra.

    But since AGW deniers acutely suffer from Dunning-Kruger effect:, they will continue to bloviate.

      Amazing how Glaciation deniers always, always resort to Ad Hom when observations trash their tidy little propaganda fed world.

      • transrp says:

        A am aware of ad hominem attacks. I am open to your telling what other term, other than stupid, one would use when describing someone who has less sense about the envirionment than trees. Also, Ad Hom has no meaning. It is probably a term made up by — well a stupid person. I see that despite over 900 words of verbiage you failed to point out a single error of either information or logic.

        When the other side is genuinely ignorant of relevant information, and dumber than trees, then what other term would you use to describe them? Professor — at bob jones university?

          Ahhh. An answer given by someone who probably could not pass a 2nd year physics course, or a second year calculus course. Am I correct? Or maybe you will tell me what your science degree is in. Mine is in engineering math and physics with graduate work in math.

          And if scientists are so dumb, how about you stup using the stuff that these dumb scientists make possible (via engineers) you know — like computers, cell phones, maybe the medicine that yout take. Yea — Just boycott all thost stupid scientist, and their useless sciency stuff

    Having an open mind, enables one to seek the truth. Most people have a closed mind, and thus are easily duped. AGW is a con. Pure and simple. (So is leftist dogma)
