“Shut-eyed Denial”

A shout-out for a review of Andrew Montford’s “The Hockey Stick Illusion” by Matt Ridley in Prospect Magazine.

Andrew Montford’s The Hockey Stick Illusion is one of the best science books in years. It exposes in delicious detail, datum by datum, how a great scientific mistake of immense political weight was perpetrated, defended and camouflaged by a scientific establishment that should now be red with shame. It is a book about principal components, data mining and confidence intervals—subjects that have never before been made thrilling. It is the biography of a graph.

I can remember when I first paid attention to the “hockey stick” graph at a conference in Cambridge. The temperature line trundled along with little change for centuries, then shot through the roof in the 20th century, like the blade of an ice-hockey stick. I had become somewhat of a sceptic about the science of climate change, but here was emphatic proof that the world was much warmer today; and warming much faster than at any time in a thousand years. I resolved to shed my doubts. I assumed that since it had been published in Nature—the Canterbury Cathedral of scientific literature—it was true.

I was not the only one who was impressed. The graph appeared six times in the Intergovernmental Panel on Climate Change (IPCC)’s third report in 2001. It was on display as a backdrop at the press conference to launch that report. James Lovelock pinned it to his wall. Al Gore used it in his film (though describing it as something else and with the Y axis upside down). Its author shot to scientific stardom. “It is hard to overestimate how influential this study has been,” said the BBC. The hockey stick is to global warming what St Paul was to Christianity.

The rest of the review is here.

Most tasty quote (my emphasis):

Well, it happens. People make mistakes in science. Corrections get made. That’s how it works, is it not? Few papers get such scrutiny as this had. But that is an even more worrying thought: how much dodgy science is being published without the benefit of an audit by Mcintyre’s ilk? As a long-time champion of science, I find the reaction of the scientific establishment more shocking than anything. The reaction was not even a shrug: it was shut-eyed denial.

    I have chatted to friends with scientific careers, and like me, they can all recall examples of dodgy science of various sorts.

    Having seen a fair few academic computer programs, I am very cautious about any conclusion that is arrived at primarily by computer analysis. This, of course, was confirmed in the case of the CRU by the HARRY_README file of programmer’s notes.

    Some time ago, the BBC did a program about the problem of contaminated cell lines in cancer research. This has surfaced again recently:


    The amazing thing to me, as an outsider to biology, is that:

    1) The results seemed to make enough sense that nobody twigged that they were testing the wrong type of cells.

    2) Some researchers knew there was a potential problem, but preferred to turn a blind eye.

    I suspect this problem is quite widespread in science. There are probably other “well known scientific facts” that are, like AGW, basically nonsense.

    I have become very cynical. For example, how many times have you read about exotic theories that are proved/disproved by minute fluctuations in the microwave background? Have you ever wondered, as I have, if it is really possible to subtract the local (and obviously asymmetric) contribution of our local galaxy, to reveal tiny fluctuations in the background signal? I don’t know, because I don’t work in the field, but I do wonder, particularly because the issue never seems to be discussed!

        My background is in anthropology and I came very close to making it a career (and sometimes regret I didn’t)–I feel compelled to stand up for the discipline. I’m not sure what “well know scientific facts” in archaeology or anthropology are basically nonsense (psychiatry is on its own :-).

        Here’s a very recent example of what they do:


        Nothing nonsensical about it at all.

        My own skepticism to AGW (which is not just the science, but the whole movement around it) probably comes out of the fundamentals I’ve learn in anthropology. In terms of archaeology and physical anthropology, we know there’s only so much physical things left behind can tell us. We know what it can’t tell us, which is much of the important things of human existence: what past people thought, how they spoke, what their values were, etc. We know what is a guess, no matter how educated, and that ultimately a guesstimate is only that. In climatology, it appears often that educated guesses are accepted as fact. Then someone’s interpretation of that fact is accepted as fact by just saying, “science says”. (yes, I know I’m simplifying here)

        In cultural anthropology we know how difficult it is to really know or understand a group of people, even if you’ve studied and lived with them for a long time. We know how easily our own biases (values, worldview, ideology) can influences analyses–if not our own (which of course we totally account for :-), for sure those of our colleagues. Humans are complex, deep, and very non-linear. Anthropology can provide insight into the human experience, but it knows that it is only one view and it knows it’s not predictive. The one thing that is certain, more than likely, is that what humans believe is real, is really just artificially constructed out of our own minds and experiences and has nothing to do with objective reality.

        People’s belief in AGW is no different, no matter how much it’s based on “science.” If that’s true just with the “as is” of this moment, how much more true is it for long-term future “predictions”? All the more so since we can see how cobbled together many of these GCMs actually are, and see exactly what biases and conditions we are building into them and leaving out. It’s like the line out of the movie “War Games”: It’s all a computer generated fantasy. How we see the future is really a projection of our own (individual and group) subconscious values, hopes, and fears. It’s more a reflection of how we see ourselves today, not how the future will actually be.

        It would be great to have anthropologists take a real look at the whole AGW movement, from a macro view as well as from a more micro view of “The Team” and other groups of players (the different blogs-including CA, advocacy groups, etc.). It’s a unique opportunity to see how a world-view is created and defended and challenged, and the outcome is in doubt. Totally fascinating!

      One of the things that people miss is that whilst the scientific method is self-correcting, it is only so in the long-term – over centuries. In the short-term, scientific consensus can be completely at odds with reality.

          Hey Moray, If 70% of what we know is wrong then 70% of what we think is wrong is actually correct.That means we could increase our understanding from 30% to 70% by conducting an experiment reasoning out the consequences and then accepting as truth what we have just disproven by scientific methods. Or even easier we could just guess and we’d get to 50%, have a few beers and you’ll soon see how wrong I am which proves I’m right.

      Sorry for OT and the long quote, but it has. Have a look at Smoot et al. (Astrophys.J.396:L1-L5,1992. Beginning of Section 3.) who discuss the first-year COBE results. They perform a multipole analysis of the measured background microwave radiation.
      After removing the foreground they have found a dipole anisotropy and emissions from the galactic plane. Motion of an observer with respect to the CMB produces a dipole anisotropy, so assuming that the whole dipole anisotropy is caused by the peculiar velocity of our galaxy they remove it and the well known CMB map remains. In the pile of WMAP publications one can probably find a similar explanation.
      The COBE measurements (almost 20 years ago) were a real breakthrough as they measured anisotropies of a relative strength of 10^-5 with statistic significance. (There are no trees in the sky…)

        Thanks for that reply – is there anything on the web about this? I guess my core worry is still that after performing all that data processing, you would certainly expect some fluctuations in the final result – how sure can anyone be that what remains is not an artifact? Can we possibly know the foreground (presumably local stuff in our galaxy) signal to this precision?

        This is very much an aside to the main discussion, but the fact that so much has been spent on collecting this data, means that finding no statistically significant fluctuations would have been inconvenient, to say the least!

          (OT continued…)

          Well, I guess you have to make sure that you have a very precise measurement and a sound understanding of all systematical errors of the measuring device. WMAP was especially designed for such a high-precision measurement.

          I discovered that the Wikipedia artical on WMAP (http://en.wikipedia.org/wiki/Wilkinson_Microwave_Anisotropy_Probe) is not bad. There is also a section on foreground removal. Furthermore,
          you can probably find lots of stuff (primary literature) in the Legacy Archive for Microwave Background Data Analysis (LAMBDA) at http://lambda.gsfc.nasa.gov
          In the left panel there is “CMB related data” and a link to foreground data. There is e.g. the Galactic Emission Mapping project GEM that tries to determine the intensity and distribution of the radio and microwave spectrum of the galaxy. Point-like sources could probably just be cut out of the CMB map as a first step. I haven’t checked these procedures in detail, I have to admit, although I have been followed the first couple of years of WMAP.
          Generally, it’s never bad to be skeptical but the outcome of this research has no political and social consequences, so the stakes are a lot lower and likely no need to fudge data to have a result that fits any preconception.

      The are not multiple lines of evidence supporting the claim that ‘only CO2 can explain the recent warming’. The only evidence for that claim are climate models. The only evidence offered to show that the climate models are useful is their ability to reproduce the past. If MWP existed and the the climate models cannot produce a warming MWP then they cannot be right about the recent warming.

      The hockey stick matters. Alarmists know this and that is why they have discarded all of their scientific principals in order to preserve it.

      Really? If it’s only one thing among others, why was it reproduced so many times?

      But the first scandal is that all those people that brandished it and wielded it at “deniers” had never, ever verified the claim AT ALL. I would be fired at my work if I did not challenge and verify the claims of my suppliers.

    XERO, very true, the Hockey Stick charade is but one drop in one bucket. The problem is there are currently several dozen buckets all catching drops. From glaciers melting in 20 years, to CRU “value added” temperature manipulation, from 32′ rise in sea level predictions, to “hiding the decline,” from tricking data, to blaming every gnat’s fart of AGW….Truly, what’s next?

    The climate has warming slightly. No one knows exactly how much or why. You had better fixate on adapting to climate change, because we lack both the technology and the resources to change it. So just deal with it.

      Yes, I agree! But it may be worse than we think!

      With its reliance on statistical analysis and models rather than on the importance of good empirical scientific observation and measurement, ‘climate science’ is more of a social science than a true ‘hard’ science. And, like other social sciences, there are many elements of the ‘science’ process which are subject to interpretation under the influence of real world forces like pursuit of funding, prestige, etc. Who knows what other areas of science-based government policy/regulation have been similarly corrupted and need to be audited?

      Now that I think about it, what areas of understanding in our lives haven’t come to rely on or are at least influenced by ‘consensus’ from perceived authority?

    • Brooks Hurd
      Posted Mar 13, 2010 at 8:37 PM | Permalink

      There is not a single peer reviewed paper which scientifically quantifies changes in golbal temperatures based on changes in the concentration of CO2. Thus any claim of the science being settled is politically not scientifically based.

      Whether or not there is a concensus about AGW, when was science aver ruled by a concensus? The scientific method involves the use of facts to prove that something is true or false. The overwhelming consensus in Europe at the beginning of the 15th Century was that the world was flat. The fact that many millions of people believed this does not make it true.

      • Posted Mar 14, 2010 at 9:51 AM | Permalink

        I think I’ve made this comment before. Medieval scholars and sailors did NOT believe the earth was flat. The scholars knew from ancient Greek philosophers the exact diameter of the earth. Sailors knew from the testimony of their own eyes that the earth is curved. Columbus argued that the earth’s diameter was less than the scholars believed, so that sailing westward to reach the Indies was possible. He was wrong; however, his error was almost exactly the correct distance to the New World — an amazing coincidence.

          One of the reasons why the Portuguese king denied to finance Columbus adventure, leading Columbus to seek support from the Spanish crown, was the knowledge that the earth was round and the knowledge of the earths diameter. Columbus claim that India was nearby Western Europe was dismissed by Portuguese scholars and sailors as nosense.

          The Portuguese scholars would have appreciated our battles with consensus science.

          Mikołaj Kopernik published his treatise “On the Revolutions of the Celestial Spheres” in 1543, the year of his death. He had written a forty page work laying out his hypothesis of heliocentrism in 1514. He kept his hypothesis within a small group of acquaintances since the consensus in the 16th Century was that the heavens circled the earth.

    11 March: Physics World: Concerns raised over Institute of Physics climate submission
    by Michael Banks, news editor of Physics World
    The hockey-stick graph, which is widely considered as a valid result in the climate-research community, was later included into the third assessment report by the United Nations Intergovernmental Panel on Climate Change (IPCC) in 2001.
    The “trick”, as mentioned by Jones in one of his e-mails to Mann, Bradley and Hughes, is a statistical method that is widely accepted in the climate community and is applied to proxy measurements in the years since 1960. It deals with the problem that some tree rings in certain parts of the world have stopped getting bigger since that time, when they ought to have been increasing in size if the world is warming. According to physicist Rasmus Benestad from the Norwegian Meteorological Institute and a blogger for realclimate.org, Jones’ reference to “hiding the decline” could have involved removing some tree-ring proxy data from the analysis after 1960 to produce a curve that agrees better with the evidence for global warming..
    BISHOP HILL COMMENT BELOW ARTICLE: Deleting proxy data and splicing in instrumental data is not “widely accepted” in the climate community. In fact Michael Mann himself has said that “No researchers in this field have ever, to our knowledge, “grafted the thermometer record onto” any reconstruction”.
    What was done in the Nature trick was to hide the evidence that the proxy records were not tracking the instrumental records in the twentieth century and were therefore not capable of reliably reconstructing earlier temperatures.
    Benestad’s statement is amazing. Is he really saying it is acceptable to remove evidence that doesn’t agree with the global warming hypothesis? Really?

    See, now THIS goes to the nub of science, of the basis of Uniformitarianism.

    Stealing from Wikipedia (because it is quicker than paraphrasing it myself):

    Uniformitarianism, in the philosophy of naturalism, assumes that the same natural laws and processes that operate in the universe now, have always operated in the universe in the past and apply everywhere in the universe. It is frequently summarized as “the present is the key to the past,” because it holds that all things continue as they were from the beginning of the world.

    You see, they are violating the very CORE of Uniformitarianism, if they are saying that what is observed in the present is DIFFERENT from what has occurred in the past. They can’t have one standard for tree rings in the last 50 years and a different one for the time before that.

    If Uniformitarianism is the gold standard for science, they were/are completely abrogating that. Actually, in doing so, they are claiming something that they have not formulated a basis for, something to SHOW convincingly that Uniformitarianism does not apply in THIS ONE SITUATION. They don’t even bother trying to argue it: they just apply it and leave it up to everyone else to discover that they’ve changed the rules of science.

    Mr Mann, Mr Briffa, Mr Jones, and assignment:

    Please inform us why the tree ring evidence of the last 50 years should have a different interpretation and quantification from all previous years and centuries.

      If you are looking for a compendium of science showing that AGW will likely not be catastrophic, probably the best to offer is “Climate Change Reconsidered” – a report produced by the Nongovernmental International Panel on Climate Change (NIPCC). See http://www.nipccreport.org/index.html

      Aren’t you missing the point. AGW is a claim, supposedly based on evidence (data). If the claim can be shown not to be soundly based, it is enough to point this out, using the data that has been already gathered.

      If I claim that Bigfoot exists, it is up to me to produce him. It is not up to the sceptics to prove he does not exist. This is the necessary asymmetry in science. In a long mathematical proof it is sufficient for a critic to show that one step is wrong, even if the rest of it is really elegant and clever.

      • Posted Mar 13, 2010 at 5:20 PM | Permalink

        It would be interesting to know how necessary that asymetry really is, and most importantly what “necessary” means in that context.

        Choosing mathematics to exemplify the scientific burden of proof is quite intriguing, as one might wonder when mathematicians infer to the best explanation. (The Church thesis, perhaps?)

        In any case, the AGW hypothesis might not rely on any existential proof, let alone a mathematical one.

    Statistically speaking, science suffers from an excess of significance. Overeager researchers often tinker too much with the statistical variables of their analysis to coax any meaningful insight from their data sets. “People are messing around with the data to find anything that seems significant, to show they have found something that is new and unusual,” Dr. Ioannidis said
    He has done systematic looks at the published literature and empirically shown us what we know deep inside our hearts,” said Muin Khoury, director of the National Office of Public Health Genomics at the U.S. Centers for Disease Control and Prevention. “We need to pay more attention to the replication of published scientific results.

      Posted Mar 12, 2010 at 5:12 PM | Permalink

      This pinpoints a problem, articulated recently by the UK’s favourite gynaecologist Baron Winston when he said on BBC radio “Science is not about what is true but about what is more likely”. This may seem horribly post-modern, but it is an accurate reflection of logical positivist philosophy – specifically, the variant re-heated to address the criticism that in its own terms logical positivism could not ever be known to be true. The logical positivists, in their eagerness to abjure any sort of metaphysical or occult object or explanation within science, sacrificed the notion of truth rather than accept the paradox that their philosophy might be true, but they could never know that it was – a metaphysical predicament par excellence.

      Subsequently logical positivism has come to be seen as _the_ philosophy of science. Thus the price of science appearing to be metaphysics-free is truth itself. The cultural ramifications have been enormous, its conception of scientific rationality becoming both the paradigm of rationality and setting agendas and criteria in the arts, the media, and social policy. In the arts for example there has been the tendency to downplay or eliminate “meaning”, as LP (with help from its mathematical logician friends) has strictures on what are meaningful statements and what are not, in favour of images (poetry), sonic effects (music), etc. The current preoccupation with “risk” is an ongoing enterprise in trying to reconcile probabilistic outcomes with a desire for 100% certainty. In media and communications, it is considered less important to adduce reasons than to cause audience reaction. And so on.

      Ironically, science has not escaped either. First, when the use of probabilistic inference is both common and expected, criticism of its applications and conclusions are bound to be deprecated. Second, when the concept of metaphysics has fallen out of common use and understanding, manifestly metaphysical entities (such as “black holes”) and teleologies (such as evolutionary style explanations) are not recognized for what they are and thrive. Third, “the truth” no longer serves as grounds for accepting a statement, position, or theory, so that changing a person’s mind on something devolves to behaviours such as tribal appeals (to shared values, myths, enemies, etc), to “consensus”, and ultimately to ad hominem attacks.

      I am in no doubt what the problem is, but in addressing it, there is a peculiar obstacle – a Fourth effect of logical positvism. In usurping for itself the paradigm of rationality, LP has caused philosophy itself to adjust. No longer is philosophy about its traditional topics and concerns – what there is, what it means, what is good, beautiful, etc. Philosphy, at least as practised by professionals, is now only about using ordinary language correctly. In that way, the contemporary philospher is allowed a vestige of respectability down the pub. It is also why the Wikipedia article on logical positivism is the way it is.

        Science is not the analytical expression of logical positivism. Nor is it about “what is more likely,” gynecological insights notwithstanding.

        Science is about what we know and how we know it, where “know” means independently of personal opinion, of cultural bias, and of subjective mind states.

        Science was formally freed from philosophy when it became explicitly based on observables, but its practitioners were finally freed of the seductions of philosophy and metaphysics only when mathematical physics was consciously applied to observational methods, as introduced by Galileo.

        In fact, science was always based on observables, but that wasn’t clear to early workers, many of whom blended philosophical speculations into their scientific work. The history of Alchemy is a prime example of that.

        Scientific theory is determinedly free of foundational axioms, which also puts an insurmountable barrier between science and philosophy.

        Philosophers are free to do what they like. Logical Positivists have no police arm. They can all, though, take a justifiable pride in their precision of thought and their internally strict methodologies. As a scientist, I can appreciate, and am grateful for, the utility of their epistemolgical methods.

        Black holes, by the way, are predicted by Einstein’s falsifiable theory and their observables are found in the center of galaxies. They’re hardly metaphysical structures. Neither are quarks, even though they cannot be observed directly, either.

        And Evolutionary Theory involves telonomy, not teleology, no matter the occasional lapses in writing or thinking by individual biologists.

        Postmodern critics of science seem invariably to make the mistake of using the foibles of scientists to demonstrate the supposed cultural boundedness of science. It’s a true naivete, mistaking science for ‘what scientists do;’ possibly induced by a blind triumphalist intellectualism. Clearly, a culture-bound phenomenon. 🙂

          Re: Pat Frank (Mar 12 23:06),
          Pat and I have lots of disagreements 🙂 but on this we agree: science has to be about phenomena that are physically observable in some way. The interesting thing is, this greatly limits its usefulness to completely describe physical phenomena, because we’re discovering hard limits to what can be observed, particularly at the quantum level… and potentially in climate science as well (cf Browning’s contributions.)

          BTW, teleonomy (“apparent purposefulness”) vs teleology (“ultimate purpose”) appears to be an exercise in obfuscation. I appreciate that chemists are aghast as these issues are seeping into their field. Who knows, this too may show up in climate science sooner or later as well. I like the picture drawn by Hull:

          Haldane [in the 1930s] can be found remarking, ‘Teleology is like a mistress to a biologist: he cannot live without her but he’s unwilling to be seen with her in public.’ Today the mistress has become a lawfully wedded wife. Biologists no longer feel obligated to apologize for their use of teleological language; they flaunt it. The only concession which they make to its disreputable past is to rename it ‘teleonomy’.

          And with that, I bid you adieu… too much “real life” these days to hang out.

          @Pat > Excuse me resorting to rhetoric, but when you say “Black holes … and their observables…” do you not see an issue?

          Let me change a couple of words in this. “The screen in front of me… and its observables…”, “The gods on Mt Olympus… and their observables…”. Which of these is your statement about black holes most like, notwithstanding your personal familiarity, preferences or attitudes, or acknowledged authority?

          My point was that to the extent that postmodern tendencies have crept into science, this is not an accident (or a happy serendipity, as some would have it) but a logical consequence of some characteristic views about science and rationality.

        • Pat Frank
          Posted Mar 13, 2010 at 5:43 PM | Permalink

          There is no issue, Luther, because the observables of black holes are predicted by theory. Your perception that there is an issue apparently arises because you seem to be supposing that the meaning of the observables is inductively, perhaps opportunistically, assigned. It’s not. The meaning of the observables is assigned by reference to predictions from an a priori and falsifiable theory.

          There is no falsifiable theory of Olympian gods. That means no observables can be assigned to such gods, except by personalized fiat. The same is not true of a physical screen displaying physically measurable phenomena.

          Here is a short history of black holes, demonstrating they were predicted from physical theory long before they were discovered.

          Postmodern tendencies may have crept into the thinking of some scientists. To the extent this is true is merely a measure of the number of scientists who fail to understand the distinction between science and opinionizing. They are intellectually deficient in their own profession.

          One will not find any postmodern ideas within any falsifiable scientific theory, meaning within Physics, Chemistry, or Biology. Nor in the theory of any other discipline coherently stemming from them such as Geology, Neuroscience, and Medicine.

          I’d also not agree that postmodern incursions follow logically from certain views about science and rationality, because postmodern thought is inherently irrational. Nothing can logically follow from irrational premises, and nor can logically legitimate views about rationality derive from a stance of irrationality. To suppose otherwise just exemplifies the human capacity for employing logical nonsequiturs to support a comforting end, e.g., in Theology. Postmodern critics of science are guilty of ignoring the logical failure of their premise, in service of a seductive intellectual triumphalism.

          People can graft postmodern sorts of meanings onto science, or may rationalize their subjectivist subversions of science by means of postmodern apologetics, but like Olympian pietetics, it is done by subjective fiat. Such subversions in science will not survive their test.

          You’ll have to reject most of science, then, too, mahong, not just quarks, electrons, and stellar black holes.

          We can’t directly see bacteria, for example. To detect bacteria we need microscopes, which workings are described by the theories of optics and radiation. Likewise, we can’t see stars, either, or planets (which are merely night sky stationary and moving lights, respectively). Nor can we see gene mutation, natural selection, or historically prior earthquakes. So, you don’t believe all of Physics, all of Chemistry (we can’t see atoms), all of Biology, and all of Medicine.

          If we really pushed your skepticism to its logically implied limits, you’d have to reject the entire world, because all of the external reality you sense are translations by your brain of proxies; the impingements of reflected photons and electrical spikes. None of us directly see or feel anything.

          You leave yourself all alone inside your brain (in which you’d have to disbelieve). Your skepticism is rationally insupportable, and is a prescription for 15th century thinking.

          You have it wrong about theory in science as well. Theories are not judged correct because they have not been falsified. In science, theories are never judged “correct.”

          Theories in science are judged valid (not “correct”) when they are deductively falsifiable, i.e., when they make predictions that are so precise and so improbable that they are put in danger of falsification. So long as they are unfalsified, they are judged as accepted.

          So, your connection of unfalsified and correct is a scientific nonsequitur.

          Pat you paint the extreme outcomes of philosophising on things, opinioning on extremes are not always the right way to describe a paradigm.

          I believe in microbes allthough I cannot see them all because there is a massive prior art and history accumulated around them. Many and various techniques to observe them.Observeables coalesce and provide convincing evidence.
          An example: people get sick , and a wizzard peering through a microscope sees many of what he calls his microbes..evidence. You cannot do that with your black holes in fact you still have to give a first sign of such evidence.

          Black holes were thought out by a wheelchair patient with lots of time on his hand, and the observable was some faint radiation coming in from lightyears away. 50years on of “science and experiments”,by a whole community of tweed clad professor Calculuses, and the only obervable is still the same faint radiation coming in from light years away, and the same scraped together “theory” around it.

          Oh and it is You that implicitely proclaims theories are correct , not me. Einstein did not predict black holes at all btw. All sorts of “phenomena” could be tweaked out of the maths he borrowed for his relativity theory.

          The falsification/validation of Einstein’s relativistic theories lies in driving together to a black hole pointed out to us by Hawkins.. If nothing happens to us, Einstein’s theory was wrong.

          This experiment is easy described but difficult to accomplish , even with the democrats and their trillions in power.

          So you see, validation of theories just by being able to dream up “experiments” is insufficient.

          Isn’t it you who’s “opinioning on extremes”, by the way ? Theories concerning the electron have passed many more falsifiable tests than black holes.

          Mahong: “Does an electron exist? I never met one so for me they don’t.”
          Mahong: “I believe in microbes allthough I cannot see them all because there is a massive prior art and history accumulated around them.”

    I just ordered a copy and I look forward to reading it.

    Several years ago I read an excellent book by Matt Ridley (the title was ‘Genome’, thoroughly recommended). Although the subject was genetics, it contained a perfect example of how the scientific consensus can be completely wrong. As I remember it: in the 1920’s a scientist in Texas first counted the number of chromosomes in the human genome: 24. This quickly became the consensus, quoted in all the text books. One research group gave up their research project because their method showed there were 23 chromosomes, and their method was therefore flawed.

    Just one small problem with this scientific consensus that lasted maybe thirty years: it was completely wrong. The actual number is 23. Ridley wrote that in fact the true number was obvious simply by looking at some photographs in text books. And yet it took decades for the truth to emerge.

    I can’t help thinking there is a strong parallel with the current claimed consensus of AGW and the hockey stick. There’s one big difference, though: this hockey stick belief will cost every one of us many, many thousands of pounds or dollars, and it will cost the world trillions of dollars. But hopefully the truth will prevail. This book – and the work of Steve McIntyre and Ross McKitrick – will have played an important part in restoring the truth, whatever it might be.

      Another example: paleontologists’ models of human evolution used to evaluate that humans diverged from the other apes 25 million years ago. Then molecular biologist found out it could not be true, because the difference between our proteins and those of chimps and gorillas was too small. The paleontologists derided them for a time, but eventually they lost: 5 million years is now standard.

      Paleontologists were then given a second blow with DNA analysis in the late 80s. They had carefully studied skulls and bones and the “consensus” was that we evolved in all regions (Africa, Europe, Asia) simultaneously. For example, Europeans descended from the Neanderthals. DNA proved that Neanderthals were not close enough for that to be possible. Paleontologists protested and fought but… I think they lost.

      The same thing happens here and there in science: a “consensus” is installed and scientists build up on it, until someone (usually a young person or an expert from another field) shakes their foundations. It is all very fun for the onlookers, but when policy is involved and very important political decisions are in the balance, it is very, very worrying to see people wielding hockey sticks so irresponsibly.

    It is easy to imagine that national military bodies have accumulated masses of data against which aspects of current climate theory can be compared. Maybe we are being 4-eyed by considering only CRU/Hadley, NOAA, GISS and the Japanese global temperature estimates. Maybe various defense establisments have heaps of relevant material also. The military might hold a compendium of good science, but unless it is revealed to the public when major public policy decisions are involved, it is open to the same criticism that was the starting point for Climate Audit (“release the data”) that intensified after Climategate.

    For example, there are plausible reasons why the military might be interested in the accuracy of satellite orbits and hence, as a derivation, the subject of sea level change.

    It is also easy to imagine a scenario whereby some Governments are reluctant to embrace a civilian version of Global Warming when a military version tells a different story. Sweden might have thought that way recently. The past USA reluctance to sign Kyoto might be a signal.

    If there is mileage in these conjectures, then where does it place the military? Presumably they are dominated by strict non-disclosure legisation, both personal and corporate. However, if the generals are sitting on data that tell a different story, surely their Governments have an obligation to release to the people that this is the case.

    This has become more important now that suspicion about civilian work has been increased by Climategate.

    Should parliaments start making statements better than “cannot confirm or deny?”

    I’m relatively new to the debate about global warming. I left it somewhere in 2001, when it was already so political that I found I didn’t have time to sort out what was right and what was wrong in all that. I came back, of course, because of Climategate, and now I am catching up.

    And I just discovered the Hockey Stick Affair and the role of Mr. McIntyre in it. I cannot say I understand yet all the scientific details of it, but I can already congratulate (and thank) Mr. McIntyre for his pluck in that incredible saga.

    May I ask readers of Climate Audit to help me with the following questions:

    a) I remember some years ago seeing many headliness about “the Republicans war on science” and the “attempt of politicians to indimidate or stifle scientists”. Was that about the Senate investigation on the Hockey Stick?

    b) Despite the Wegman report, I see the Hockey Stick is still around and Realclimate says it is still valid. Is it, or is it not?

    c) Are there some other proxies of past temperature levels that produce a Hockey Stick and that have been audited (this time)?

    Thank you.

      a) Dunno. “The Republican War on Science” was a book by Chris Mooney. Quite how the Republicans were waging war on science when they were voting in huge spending on science in general and climate science in particular, was and is baffling to me. But who am I compared to a mega-genius like Chris Mooney?

      b) The Hockey Stick is invalid. Realclimate is talking nonsense. But its well paid and lucrative nonsense.

      c) Yes. The Wegman Report mentions those. As Steve reported, they use the same dubious proxies over and over and the same bad statistical methods over and over and call themselves “independent”. It would be funny if it wasn’t so serious.

      My recollection, viz question a) FWIW, is that a good bit of the uproar came from J. Hansen of NASA/GISS during the 2001-2004 timeframe complaining that his work outputs/opinions were being suppressed due to the political views of his organization;s management chain.

    The usefulness of the concept of ‘electron’ is not bound to your belief in it.

    No it is not, but all of electronics and our present high-tech world, can (and has been so) be construed without believing in it.

    from wikipedia:
    the electron is a subatomic particle that carries a negative electric charge.

    We all know particles aren’t “out there” don’t we ?
    So it carries a negative charge? I’d say the charge “it” carries has quite positive effects.

    electrons are snakeoil from Mr Gore’s cabinet. Next to the bottle with black holes.

    I cherish the theory that on Pandora/2 rocks fly faster and higher than on Pandora/1. And they eat black holes for lunch.

    Einstein did not object to it.

    It can be falsified by going there and checking it out, so you better validate my theory now or you have problems with oneuniverse and pat.

    It is a valid theory.

    Going to propose a giant collander now to the EU , to get more details about it.

    What are the electron-free explanations of all electronics that you refer to – would you mind providing a reference? Are these explanations any good?

    Science doesn’t ask you to believe in the electron. It’s just proved to be a very useful concept in describing and predicting certain observed phenomena in nature. You may choose to construe modern electronics without recourse to the scientific understanding used to design them, yet the fact that the designs repeatedly work is good evidence that the scientific concepts involved in the designs are not just ‘snake oil’, but the opposite – they are profoundly useful.

      oneuniverse, your points are well-taken, but mahong clearly has trouble discerning the difference between bald assertions (the moon is made of green cheese) and deduction from a falsifiable theory. He’s also now bordering on trolldom, and it’s probably best to leave off.

      Your electron concept might be profoundly useful -I do not know of any electronics hobbyist having a jar with electrons on the shelf though-useful for oneuniverse but not real.

      Locking in on false platonic imagery, like all of present day scientific education nowadays, stops progress and had its day.

      I did not say anything like the moon is made from green cheese.
      Interesting thought on the moon project though is the way Nasa handled the primordial question if there were water on the moon(main component of cheese ). aaah a few billions spent in the 60s-90s by the “scientists” and they were still not too sure about it . 2009 they had to send in a missile on the moon to be sure. They’re still not too sure.

      black holes : nothing falsifiable there, all snakeoil. Haven’t seen a valid argument from you guys on it.

    Black holes are a solution to Einstein’s field equations, mahong. That makes them a prediction of his theory. Whatever else is “tweaked out” is also a prediction, and a test, and is how science proceeds.

    So BH are something mathematical not physical, thanks for sorting this out for me.
    I fail to see where your test’s been validated, your science is proceeding? on a computer screen? facebook ??

    If you haven’t already, I would encourage readers to get a copy of the Bishop’s new book. It is a great and exciting read, a real detective story. You will find a good description of Steve McIntyre’s first forays into climate auditing, his discovery of problems with MBH98s Hockey Stick, his partnership with Ross McKittrick to write a response (MM2003), the politiics and difficulty of getting the report published in Nature, the nascent beginning of Climate Audit. You will get some background on some names you might have heard about: Amman and Wahl, Schneider, Mann, Jones and D’Arrigo. The Bishop is a very good writer, the explanations of events and the math are written in a style that is accessible to a wide range of readers. I am beginning to understand better how the Hockey Stick was broken, why just having a few hockey stick shapes in the 20th century allowed the reconstructions to take on the hockey stick shape. I was astounded to find that the R-squared statistic generated by the Team when the proxies were correlated with the temperature data was close to zero, essentially there was very little correlation between (mainly) tree rings and temperature, and that it was known that bristlecone pines in the White Mtns were thought to have had increased tree rings in the 20th century due to CO2 fertilization, and not increased local temperature.

    Then I found out that Steve M. played Rugby at Oxford and that did it. My appreciation of him is even higher after hearing that! (I played American Football
    in high school.)

      yeah, the “difficulty of getting the report published in Nature”

      In my (thanks god) less mediatized field of lithosphere’s thermal structure, there’s a clown who self allegedly debunked the accepted thermal models of the lithosphere. However, he is not able to publish in any reputable journal, and he usually ends up in some E&E-style journal or he simply uploads his manuscript in arXiv. Funnily enough, he complains that he is being censored by the community.
      Others simply think that his work is crap.

      Conclusion is: when you’re work cannot pass through the reviewing stage because it’s crappy, blame community censorship.

        As for the community admitting censorship, well, to come back to my above example, the clown managed to publish in some little journal, with the result of receiving a comment to his article calling for the “community to ignore his work”, and he was not able to publish his subsequent works. “Censorship”, “shut-eyed denial”, that’s how he must feel…

The fact is that realclimate never actually looks at the actual work, but relies on half-truths, ad homs and red herrings. We’d love to see you try defending their smears here.

          Anyway, I was just reading the comments based on this post and thought I’d say that RomanM gave a very good description and since I am ‘writing’ more than I’m ‘linking’ this might just make it through.

        Nono, you claim to work on the lithosphere. If so, you might have heard of a journal called GRL, one of the most highly regarded in the field? Look at vol 32, L03710.
        Also, if you are really a scientist, you will know that it is very difficult to get even good work into Nature.

          You really need to read some of Steve’s responses to these supposed refutations. Go to the left hand margin here and click on the Categories drop-down. It will let you find threads on the various papers, such as Wahl and Ammann.

          I tried forming a response to the links you sent above. The problem I’ve run into is that the graphs both here and on RC don’t seem to work anymore. This makes it difficult to make an understandable presentation. The first two links to early Real Climate posts don’t really provide much to work with. Steve was supported in his claims both by the NAS panel and by the ad hoc panel of Wegman. Of course the team claim that NAS supported Mann, but this isn’t correct. If you read their report, what they said is that while the off-centered PCs weren’t correct,there were plenty of other multiproxy studies which supported Mann independently. But this is just wrong. All the other multi-proxy studies at that time and since for that matter, use the same proxies cherry-picked from Mann’s list, or variations on the same theme. I hate just telling you to read all the appropriate threads here, but they have things in much more detail than I can provide. I would be happy to find answers to specific questions related to a given “refutation” of one of Steve’s findings.

    The reasoon why I did’t mention the variations and details of the temperature gradient is because they are not relavent to the point. An inversion is not the zone which stays exactly -19C and emits all radiation into space as required by the loony theory of warmists. What keeps radiation from going into space from -18C, -17C, -16C, etc. When you argue just to argue, you need to explain the relevance.

    Somewhere else where’s there’s “shut-eyed denial” is on Tamino’s blog about the Beenstock & Reingewertz paper on the independence of the trend in CO2 concentration and temperature. Tamino first quotes at length from what seems to be an undergrad textbook, then applies the wrong test to reject the null unit root hypothesis. When the use of the wrong test is pointed out, he effectively sticks his fingers in his ears and shouts “lalalalalalalala I can’t hear you !”. And his claque of worse than ignorant prats are uttering drunken shouts of approval. Score, VS “lots”, Tamino 0. God they’re thick.

      yeah, VS shows that, from the statistical properties of the temperature serie, it can be seen as a particular realization of a stochastic process (here, a random walk).

      Actually, everything, from the gravity field to topography, can be seen as a particular realization of some stochastic process provided you chose the right autocorrelation structure. (Contouring techniques such as kriging as based on that.)

      Does it mean that temperature evolution or topography or the gravity field are in essence random processes? (That Newton law is a hoax?) No, and VS admits it.

      Which is why I find the remark of limited interest.

        The discomfort arises from the blackholes being so unreachable.

        I might be wrong,but there is not much to crow about the BH either which is what I am saying. There are no alternative paths to gain any knowledge from them except someone interpretes supposed Stellar Convergences or alledged bent radiation seen over a couple of decades as the manifestation of a blackhole.

        Pinning scant observation on one theory is dubious.
        This is not an issue of getting a nobel, discovering something, but of pointing out the futility in this area of scurtiny.
        OK it is “nice” to develop a concept, but it comes with its cost: Generations of physics students have to master the concept of BHs and “string theory” now.
        It reminds me of people having to learn ball trigonometry which served no purpose whatsoever for 10generations except 5 people. caveat : trigonometry is true and valid, BHs we even do not know if they are true. You can come with Einstein as much as you want: You do not know if BHs exist.

        The glitterings on computer screens can be explained by spacetime being not the platonic straightlines (or smooth curvy lines) but rather a more complicated setup.

        The William of Ockham Rasor which compels the scientific establishment to take the simplest solution/explanation for truth is distinctly invalid in the large maybe also in the small. Or rather in the “unreachable”. The ultimate physical reality is not the anthropgenically appealing simplest solution.
