The “exoneration” by Climategate investigations (like Muir Russell) that never bother to talk to skeptics, create an impossible conundrum of having essentially a trial with judge, jury, reporters, spectators, and defendant, but no plaintiff. The plaintiff is locked outside the courtroom sitting in the hall hollering and hoping the jury hears some of what he has to say.
Given this, I thought it valuable to revisit this Caltech lecture on the state of science and consensus by the late Michael Crichton.

Caltech Michelin Lecture – January 17, 2003
My topic today sounds humorous but unfortunately I am serious. I am going to argue that extraterrestrials lie behind global warming. Or to speak more precisely, I will argue that a belief in extraterrestrials has paved the way, in a progression of steps, to a belief in global warming.
Charting this progression of belief will be my task today. Let me say at once that I have no desire to discourage anyone from believing in either extraterrestrials or global warming. That would be quite impossible to do.
Rather, I want to discuss the history of several widely-publicized beliefs and to point to what I consider an emerging crisis in the whole enterprise of science-namely the increasingly uneasy relationship between hard science and public policy.
I have a special interest in this because of my own upbringing. I was born in the midst of World War II, and passed my formative years at the height of the Cold War. In school drills, I dutifully crawled under my desk in preparation for a nuclear attack.
It was a time of widespread fear and uncertainty, but even as a child I believed that science represented the best and greatest hope for mankind. Even to a child, the contrast was clear between the world of politics-a world of hate and danger, of irrational beliefs and fears, of mass manipulation and disgraceful blots on human history. In contrast, science held different values-international in scope, forging friendships and working relationships across national boundaries and political systems, encouraging a dispassionate habit of thought, and ultimately leading to fresh knowledge and technology that would benefit all mankind.
The world might not be a very good place, but science would make it better. And it did. In my lifetime, science has largely fulfilled its promise. Science has been the great intellectual adventure of our age, and a great hope for our troubled and restless world. But I did not expect science merely to extend lifespan, feed the hungry, cure disease, and shrink the world with jets and cell phones.
I also expected science to banish the evils of human thought—prejudice and superstition, irrational beliefs and false fears. I expected science to be, in Carl Sagan’s memorable phrase, “a candle in a demon haunted world.” And here, I am not so pleased with the impact of science. Rather than serving as a cleansing force, science has in some instances been seduced by the more ancient lures of politics and publicity.
Some of the demons that haunt our world in recent years are invented by scientists. The world has not benefited from permitting these demons to escape free. But let’s look at how it came to pass.
Cast your minds back to 1960. John F. Kennedy is president, commercial jet airplanes are just appearing, the biggest university mainframes have 12K of memory. And in Green Bank, West Virginia at the new National Radio Astronomy Observatory, a young astrophysicist named Frank Drake runs a two-week project called Ozma, to search for extraterrestrial signals. A signal is received, to great excitement. It turns out to be false, but the excitement remains.
In 1960, Drake organizes the first SETI conference, and came up with the now-famous Drake equation: N=N*fp ne fl fi fc fL
[where N is the number of stars in the Milky Way galaxy; fp is the fraction with planets; ne is the number of planets per star capable of supporting life; fl is the fraction of planets where life evolves; fi is the fraction where intelligent life evolves; and fc is the fraction that communicates; and fL is the fraction of the planet’s life during which the communicating civilizations live.]
This serious-looking equation gave SETI a serious footing as a legitimate intellectual inquiry. The problem, of course, is that none of the terms can be known, and most cannot even be estimated. The only way to work the equation is to fill in with guesses. And guesses-just so we’re clear-are merely expressions of prejudice.
Nor can there be “informed guesses.” If you need to state how many planets with life choose to communicate, there is simply no way to make an informed guess. It’s simply prejudice.
As a result, the Drake equation can have any value from “billions and billions” to zero. An expression that can mean anything means nothing. Speaking precisely, the Drake equation is literally meaningless, and has nothing to do with science. I take the hard view that science involves the creation of testable hypotheses. The Drake equation cannot be tested and therefore SETI is not science. SETI is unquestionably a religion.
Faith is defined as the firm belief in something for which there is no proof. The belief that the Koran is the word of God is a matter of faith. The belief that God created the universe in seven days is a matter of faith. The belief that there are other life forms in the universe is a matter of faith. There is not a single shred of evidence for any other life forms, and in forty years of searching, none has been discovered.There is absolutely no evidentiary reason to maintain this belief. SETI is a religion.
One way to chart the cooling of enthusiasm is to review popular works on the subject. In 1964, at the height of SETI enthusiasm, Walter Sullivan of the NY Times wrote an exciting book about life in the universe entitled WE ARE NOT ALONE. By 1995, when Paul Davis wrote a book on the same subject, he titled it ARE WE ALONE? ( Since 1981, there have in fact been four books titled ARE WE ALONE.) More recently we have seen the rise of the so-called “Rare Earth” theory which suggests that we may, in fact, be all alone.
Again, there is no evidence either way.
Back in the sixties, SETI had its critics, although not among astrophysicists and astronomers. The biologists and paleontologists were harshest. George Gaylord Simpson of Harvard sneered that SETI was a “study without a subject,” and it remains so to the present day. But scientists in general have been indulgent toward SETI, viewing it either with bemused tolerance, or with indifference. After all, what’s the big deal? It’s kind of fun. If people want to look, let them. Only a curmudgeon would speak harshly of SETI. It wasn’t worth the bother.
And of course, it is true that untestable theories may have heuristic value. Of course, extraterrestrials are a good way to teach science to kids. But that does not relieve us of the obligation to see the Drake equation clearly for what it is-pure speculation in quasi-scientific trappings.
The fact that the Drake equation was not greeted with screams of outrage-similar to the screams of outrage that greet each Creationist new claim, for example-meant that now there was a crack in the door, a loosening of the definition of what constituted legitimate scientific procedure. And soon enough, pernicious garbage began to squeeze through the cracks.
Now let’s jump ahead a decade to the 1970s, and Nuclear Winter. In 1975, the National Academy of Sciences reported on “Long-Term Worldwide Effects of Multiple Nuclear Weapons Detonations” but the report estimated the effect of dust from nuclear blasts to be relatively minor.
In 1979, the Office of Technology Assessment issued a report on “The Effects of Nuclear War” and stated that nuclear war could perhaps produce irreversible adverse consequences on the environment. However, because the scientific processes involved were poorly understood, the report stated it was not possible to estimate the probable magnitude of such damage.
Three years later, in 1982, the Swedish Academy of Sciences commissioned a report entitled “The Atmosphere after a Nuclear War: Twilight at Noon,” which attempted to quantify the effect of smoke from burning forests and cities. The authors speculated that there would be so much smoke that a large cloud over the northern hemisphere would reduce incoming sunlight below the level required for photosynthesis, and that this would last for weeks or even longer.

| The Drake Equation. Pure science -or Pure Hooey? |
The following year, five scientists including Richard Turco and Carl Sagan published a paper in Science called “Nuclear Winter: Global Consequences of Multiple Nuclear Explosions.” This was the so-called TTAPS report, which attempted to quantify more rigorously the atmospheric effects, with the added credibility to be gained from an actual computer model of climate.
At the heart of the TTAPS undertaking was another equation, never specifically expressed, but one that could be paraphrased as follows:
Ds = Wn Ws Wh Tf Tb Pt Pr Pe etc
(The amount of tropospheric dust = # warheads x size warheads x warhead detonation height x flammability of targets x Target burn duration x Particles entering the Troposphere x Particle reflectivity x Particle endurance, and so on.)
The similarity to the Drake equation is striking. As with the Drake equation, none of the variables can be determined. None at all. The TTAPS study addressed this problem in part by mapping out different wartime scenarios and assigning numbers to some of the variables, but even so, the remaining variables were-and are-simply unknowable. Nobody knows how much smoke will be generated when cities burn, creating particles of what kind, and for how long. No one knows the effect of local weather conditions on the amount of particles that will be injected into the troposphere. No one knows how long the particles will remain in the troposphere. And so on.
And remember, this is only four years after the OTA study concluded that the underlying scientific processes were so poorly known that no estimates could be reliably made.
Nevertheless, the TTAPS study not only made those estimates, but concluded they were catastrophic. According to Sagan and his coworkers, even a limited 5,000 megaton nuclear exchange would cause a global temperature drop of more than 35 degrees Centigrade, and this change would last for three months.
The greatest volcanic eruptions that we know of changed world temperatures somewhere between .5 and 2 degrees Centigrade. Ice ages changed global temperatures by 10 degrees. Here we have an estimated change three times greater than any ice age.
One might expect it to be the subject of some dispute. But Sagan and his coworkers were prepared, for nuclear winter was from the outset the subject of a well-orchestrated media campaign. The first announcement of nuclear winter appeared in an article by Sagan in the Sunday supplement, Parade. The very next day, a highly-publicized, high-profile conference on the long-term consequences of nuclear war was held in Washington, chaired by Carl Sagan and Paul Ehrlich, the most famous and media-savvy scientists of their generation.
Sagan appeared on the Johnny Carson show 40 times. Ehrlich was on 25 times. Following the conference, there were press conferences, meetings with congressmen, and so on. The formal papers in Science came months later.
This is not the way science is done, it is the way products are sold. The real nature of the conference is indicated by these artists’ renderings of the effect of nuclear winter. (Not Shown)
I cannot help but quote the caption for figure 5: “Shown here is a tranquil scene in the north woods. A beaver has just completed its dam, two black bears forage for food, a swallow-tailed butterfly flutters in the foreground, a loon swims quietly by, and a kingfisher searches for a tasty fish.” Hard science if ever there was.
At the conference in Washington, during the question period, Ehrlich was reminded that after Hiroshima and Nagasaki, scientists were quoted as saying nothing would grow there for 75 years, but in fact melons were growing the next year. So, he was asked, how accurate were these findings now?
Ehrlich answered by saying “I think they are extremely robust. Scientists may have made statements like that, although I cannot imagine what their basis would have been, even with the state of science at that time, but scientists are always making absurd statements, individually, in various places. What we are doing here, however, is presenting a consensus of a very large group of scientists”
I want to pause here and talk about this notion of consensus, and the rise of what has been called consensus science. I regard consensus science as an extremely pernicious development that ought to be stopped cold in its tracks. Historically, the claim of consensus has been the first refuge of scoundrels; it is a way to avoid debate by claiming that the matter is already settled. Whenever you hear the consensus of scientists agrees on something or other, reach for your wallet, because you’re being had.
Let’s be clear: the work of science has nothing whatever to do with consensus. Consensus is the business of politics. Science, on the contrary, requires only one investigator who happens to be right, which means that he or she has results that are verifiable by reference to the real world.
In science consensus is irrelevant. What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus. There is no such thing as consensus science. If it’s consensus, it isn’t science. If it’s science, it isn’t consensus. Period.
In addition, let me remind you that the track record of the consensus is nothing to be proud of. Let’s review a few cases.
In past centuries, the greatest killer of women was fever following childbirth. One woman in six died of this fever.
In 1795, Alexander Gordon of Aberdeen suggested that the fevers were infectious processes, and he was able to cure them. The consensus said no.
In 1843, Oliver Wendell Holmes claimed puerperal fever was contagious, and presented compelling evidence. The consensus said no.
In 1849, Semmelweiss demonstrated that sanitary techniques virtually eliminated puerperal fever in hospitals under his management. The consensus said he was a Jew, ignored him, and dismissed him from his post. There was in fact no agreement on puerperal fever until the start of the twentieth century. Thus the consensus took one hundred and twenty five years to arrive at the right conclusion despite the efforts of the prominent “skeptics” around the world, skeptics who were demeaned and ignored. And despite the constant ongoing deaths of women.
There is no shortage of other examples. In the 1920s in America, tens of thousands of people, mostly poor, were dying of a disease called pellagra. The consensus of scientists said it was infectious, and what was necessary was to find the “pellagra germ.” The US government asked a brilliant young investigator, Dr. Joseph Goldberger, to find the cause. Goldberger concluded that diet was the crucial factor. The consensus remained wedded to the germ theory.
Goldberger demonstrated that he could induce the disease through diet. He demonstrated that the disease was not infectious by injecting the blood of a pellagra patient into himself, and his assistant. They and other volunteers swabbed their noses with swabs from pellagra patients, and swallowed capsules containing scabs from pellagra rashes in what were called “Goldberger’s filth parties.” Nobody contracted pellagra.
The consensus continued to disagree with him. There was, in addition, a social factor-southern States disliked the idea of poor diet as the cause, because it meant that social reform was required. They continued to deny it until the 1920s. Result-despite a twentieth century epidemic, the consensus took years to see the light.
Probably every schoolchild notices that South America and Africa seem to fit together rather snugly, and Alfred Wegener proposed, in 1912, that the continents had in fact drifted apart. The consensus sneered at continental drift for fifty years. The theory was most vigorously denied by the great names of geology-until 1961, when it began to seem as if the sea floors were spreading. The result: it took the consensus fifty years to acknowledge what any schoolchild sees.
And shall we go on? The examples can be multiplied endlessly. Jenner and smallpox, Pasteur and germ theory. Saccharine, margarine, repressed memory, fiber and colon cancer, hormone replacement therapy. The list of consensus errors goes on and on.
Finally, I would remind you to notice where the claim of consensus is invoked. Consensus is invoked only in situations where the science is not solid enough.
Nobody says the consensus of scientists agrees that E=mc2. Nobody says the consensus is that the sun is 93 million miles away. It would never occur to anyone to speak that way.
But back to our main subject. What I have been suggesting to you is that nuclear winter was a meaningless formula, tricked out with bad science, for policy ends. It was political from the beginning, promoted in a well-orchestrated media campaign that had to be planned weeks or months in advance.
Further evidence of the political nature of the whole project can be found in the response to criticism. Although Richard Feynman was characteristically blunt, saying, “I really don’t think these guys know what they’re talking about,” other prominent scientists were noticeably reticent. Freeman Dyson was quoted as saying “It’s an absolutely atrocious piece of science but who wants to be accused of being in favor of nuclear war?” And Victor Weisskopf said, “The science is terrible but—perhaps the psychology is good.”
The nuclear winter team followed up the publication of such comments with letters to the editors denying that these statements were ever made, though the scientists since then have subsequently confirmed their views. At the time, there was a concerted desire on the part of lots of people to avoid nuclear war. If nuclear winter looked awful, why investigate too closely? Who wanted to disagree? Only people like Edward Teller, the “father of the H bomb.”
Teller said, “While it is generally recognized that details are still uncertain and deserve much more study, Dr. Sagan nevertheless has taken the position that the whole scenario is so robust that there can be little doubt about its main conclusions.”
Yet for most people, the fact that nuclear winter was a scenario riddled with uncertainties did not seem to be relevant. I say it is hugely relevant. Once you abandon strict adherence to what science tells us, once you start arranging the truth in a press conference, then anything is possible.
In one context, maybe you will get some mobilization against nuclear war. But in another context, you get Lysenkoism. In another, you get Nazi euthanasia. The danger is always there, if you subvert science to political ends.
That is why it is so important for the future of science that the line between what science can say with certainty, and what it cannot, be drawn clearly-and defended.
What happened to Nuclear Winter? As the media glare faded, its robust scenario appeared less persuasive; John Maddox, editor of Nature, repeatedly criticized its claims; within a year, Stephen Schneider, one of the leading figures in the climate model, began to speak of “nuclear autumn.” It just didn’t have the same ring.
A final media embarrassment came in 1991, when Carl Sagan predicted on Nightline that Kuwaiti oil fires would produce a nuclear winter effect, causing a “year without a summer,” and endangering crops around the world. Sagan stressed this outcome was so likely that “it should affect the war plans.” None of it happened.
What, then, can we say were the lessons of Nuclear Winter? I believe the lesson was that with a catchy name, a strong policy position and an aggressive media campaign, nobody will dare to criticize the science, and in short order, a terminally weak thesis will be established as fact.
After that, any criticism becomes beside the point. The war is already over without a shot being fired. That was the lesson, and we had a textbook application soon afterward, with second hand smoke.
In 1993, the EPA announced that second-hand smoke was “responsible for approximately 3,000 lung cancer deaths each year in nonsmoking adults,” and that it ” impairs the respiratory health of hundreds of thousands of people.” In a 1994 pamphlet the EPA said that the eleven studies it based its decision on were not by themselves conclusive, and that they collectively assigned second-hand smoke a risk factor of 1.19. (For reference, a risk factor below 3.0 is too small for action by the EPA. or for publication in the New England Journal of Medicine, for example.)
Furthermore, since there was no statistical association at the 95% confidence limits, the EPA lowered the limit to 90%. They then classified second-hand smoke as a Group-A Carcinogen.
This was openly fraudulent science, but it formed the basis for bans on smoking in restaurants, offices, and airports. California banned public smoking in 1995. Soon, no claim was too extreme. By 1998, the Christian Science Monitor was saying that “Second-hand smoke is the nation’s third-leading preventable cause of death.” The American Cancer Society announced that 53,000 people died each year of second-hand smoke. The evidence for this claim is nonexistent.
In 1998, a Federal judge held that the EPA had acted improperly, had “committed to a conclusion before research had begun”, and had “disregarded information and made findings on selective information.”
The reaction of Carol Browner, head of the EPA was: “We stand by our science; there’s wide agreement. The American people certainly recognize that exposure to second hand smoke brings a whole host of health problems.”
Again, note how the claim of consensus trumps science. In this case, it isn’t even a consensus of scientists that Browner evokes! It’s the consensus of the American people.
Meanwhile, ever-larger studies failed to confirm any association. A large, seven-country WHO study in 1998 found no association. Nor have well-controlled subsequent studies, to my knowledge. Yet we now read, for example, that second-hand smoke is a cause of breast cancer. At this point you can say pretty much anything you want about second-hand smoke.
As with nuclear winter, bad science is used to promote what most people would consider good policy. I certainly think it is. I don’t want people smoking around me. So who will speak out against banning second-hand smoke? Nobody, and if you do, you’ll be branded a shill of RJ Reynolds. A big tobacco flunky. But the truth is that we now have a social policy supported by the grossest of superstitions.
And we’ve given the EPA a bad lesson in how to behave in the future. We’ve told them that cheating is the way to succeed.
As the twentieth century drew to a close, the connection between hard scientific fact and public policy became increasingly elastic. In part this was possible because of the complacency of the scientific profession; in part because of the lack of good science education among the public; in part, because of the rise of specialized advocacy groups which have been enormously effective in getting publicity and shaping policy; and in great part because of the decline of the media as an independent assessor of fact.
The deterioration of the American media is dire loss for our country. When distinguished institutions like the New York Times can no longer differentiate between factual content and editorial opinion, but rather mix both freely on their front page, then who will hold anyone to a higher standard?
And so, in this elastic anything-goes world where science-or non-science-is the hand maiden of questionable public policy, we arrive at last at global warming. It is not my purpose here to rehash the details of this most magnificent of the demons haunting the world. I would just remind you of the now-familiar pattern by which these things are established.
Evidentiary uncertainties are glossed over in the unseemly rush for an overarching policy, and for grants to support the policy by delivering findings that are desired by the patron.
Next, the isolation of those scientists who won’t get with the program, and the characterization of those scientists as outsiders and “skeptics” in quotation marks-suspect individuals with suspect motives, industry flunkies, reactionaries, or simply anti-environmental nut-cases.
In short order, debate ends, even though prominent scientists are uncomfortable about how things are being done. When did “skeptic” become a dirty word in science? When did a skeptic require quotation marks around it?
To an outsider, the most significant innovation in the global warming controversy is the overt reliance that is being placed on models. Back in the days of nuclear winter, computer models were invoked to add weight to a conclusion: “These results are derived with the help of a computer model.”
But now, large-scale computer models are seen as generating data in themselves. No longer are models judged by how well they reproduce data from the real world-increasingly, models provide the data.
As if they were themselves a reality. And indeed they are, when we are projecting forward. There can be no observational data about the year 2100. There are only model runs. This fascination with computer models is something I understand very well.
Richard Feynmann called it a disease. I fear he is right. Because only if you spend a lot of time looking at a computer screen can you arrive at the complex point where the global warming debate now stands. Nobody believes a weather prediction twelve hours ahead. Now we’re asked to believe a prediction that goes out 100 years into the future?
And make financial investments based on that prediction? Has everybody lost their minds?
Stepping back, I have to say the arrogance of the model-makers is breathtaking. There have been, in every century, scientists who say they know it all. Since climate may be a chaotic system-no one is sure-these predictions are inherently doubtful, to be polite. But more to the point, even if the models get the science spot-on, they can never get the sociology. To predict anything about the world a hundred years from now is simply absurd.
Look: If I was selling stock in a company that I told you would be profitable in 2100, would you buy it? Or would you think the idea was so crazy that it must be a scam?
Let’s think back to people in 1900 in, say, New York. If they worried about people in 2000, what would they worry about? Probably: Where would people get enough horses? And what would they do about all the horse****?
Horse pollution was bad in 1900, think how much worse it would be a century later, with so many more people riding horses? But of course, within a few years, nobody rode horses except for sport.
And in 2000, France was getting 80% its power from an energy source that was unknown in 1900. Germany, Switzerland, Belgium and Japan were getting more than 30% from this source, unknown in 1900. Remember, people in 1900 didn’t know what an atom was.
They didn’t know its structure. They also didn’t know what a radio was, or an airport, or a movie, or a television, or a computer, or a cell phone, or a jet, an antibiotic, a rocket, a satellite, an MRI, ICU, IUD, IBM, IRA, ERA, EEG, EPA, IRS, DOD, PCP, HTML, internet. interferon, instant replay, remote sensing, remote control, speed dialing, gene therapy, gene splicing, genes, spot welding, heat-seeking, bipolar, prozac, leotards, lap dancing, email, tape recorder, CDs, airbags, plastic explosive, plastic, robots, cars, liposuction, transduction, superconduction, dish antennas, step aerobics, smoothies, twelve-step, ultrasound, nylon, rayon, teflon, fiber optics, carpal tunnel, laser surgery, laparoscopy, corneal transplant, kidney transplant, AIDS. None of this would have meant anything to a person in the year 1900. They wouldn’t know what you are talking about.
Now. You tell me you can predict the world of 2100. Tell me it’s even worth thinking about. Our models just carry the present into the future. They’re bound to be wrong. Everybody who gives a moment’s thought knows it.
I remind you that in the lifetime of most scientists now living, we have already had an example of dire predictions set aside by new technology. I refer to the green revolution. In 1960, Paul Ehrlich said, “The battle to feed humanity is over. In the 1970s the world will undergo famines-hundreds of millions of people are going to starve to death.”
Ten years later, he predicted four billion people would die during the 1980s, including 65 million Americans. The mass starvation that was predicted never occurred, and it now seems it isn’t ever going to happen. Nor is the population explosion going to reach the numbers predicted even ten years ago.
In 1990, climate modelers anticipated a world population of 11 billion by 2100. Today, some people think the correct number will be 7 billion and falling. But nobody knows for sure. But it is impossible to ignore how closely the history of global warming fits on the previous template for nuclear winter.
Just as the earliest studies of nuclear winter stated that the uncertainties were so great that probabilities could never be known, so, too the first pronouncements on global warming argued strong limits on what could be determined with certainty about climate change.
The 1995 IPCC draft report said, “Any claims of positive detection of significant climate change are likely to remain controversial until uncertainties in the total natural variability of the climate system are reduced.” It also said, “No study to date has positively attributed all or part of observed climate changes to anthropogenic causes.”
Those statements were removed, and in their place appeared: “The balance of evidence suggests a discernable human influence on climate.” What is clear, however, is that on this issue, science and policy have become inextricably mixed to the point where it will be difficult, if not impossible, to separate them out. It is possible for an outside observer to ask serious questions about the conduct of investigations into global warming, such as whether we are taking appropriate steps to improve the quality of our observational data records, whether we are systematically obtaining the information that will clarify existing uncertainties, whether we have any organized disinterested mechanism to direct research in this contentious area.
The answer to all these questions is no. We don’t. In trying to think about how these questions can be resolved, it occurs to me that in the progression from SETI to nuclear winter to second-hand smoke to global warming, we have one clear message, and that is that we can expect more and more problems of public policy dealing with technical issues in the future-problems of ever greater seriousness, where people care passionately on all sides.
And at the moment we have no mechanism to get good answers. So I will propose one. Just as we have established a tradition of double-blinded research to determine drug efficacy, we must institute double-blinded research in other policy areas as well. Certainly the increased use of computer models, such as GCMs, cries out for the separation of those who make the models from those who verify them.
The fact is that the present structure of science is entrepreneurial, with individual investigative teams vying for funding from organizations that all too often have a clear stake in the outcome of the research-or appear to, which may be just as bad. This is not healthy for science.
Sooner or later, we must form an independent research institute in this country. It must be funded by industry, by government, and by private philanthropy, both individuals and trusts. The money must be pooled, so that investigators do not know who is paying them. The institute must fund more than one team to do research in a particular area, and the verification of results will be a foregone requirement: teams will know their results will be checked by other groups.
In many cases, those who decide how to gather the data will not gather it, and those who gather the data will not analyze it. If we were to address the land temperature records with such rigor, we would be well on our way to an understanding of exactly how much faith we can place in global warming, and therefore with what seriousness we must address this.
I believe that as we come to the end of this litany, some of you may be saying, well what is the big deal, really. So we made a few mistakes. So a few scientists have overstated their cases and have egg on their faces. So what?
Well, I’ll tell you.
In recent years, much has been said about the post-modernist claims about science to the effect that science is just another form of raw power, tricked out in special claims for truth-seeking and objectivity that really have no basis in fact. Science, we are told, is no better than any other undertaking. These ideas anger many scientists, and they anger me. But recent events have made me wonder if they are correct.
We can take as an example the scientific reception accorded a Danish statistician, Bjorn Lomborg, who wrote a book called The Skeptical Environmentalist.
The scientific community responded in a way that can only be described as disgraceful. In professional literature, it was complained he had no standing because he was not an earth scientist. His publisher, Cambridge University Press, was attacked with cries that the editor should be fired, and that all right-thinking scientists should shun the press. The past president of the AAAS wondered aloud how Cambridge could have ever “published a book that so clearly could never have passed peer review.” (But of course, the manuscript did pass peer review by three earth scientists on both sides of the Atlantic, and all recommended publication.)
But what are scientists doing attacking a press? Is this the new McCarthyism-coming from scientists? Worst of all was the behavior of the Scientific American, which seemed intent on proving the post-modernist point that it was all about power, not facts.
The Scientific American attacked Lomborg for eleven pages, yet only came up with nine factual errors despite their assertion that the book was “rife with careless mistakes.”
It was a poor display, featuring vicious ad hominem attacks, including comparing him to a Holocaust denier. The issue was captioned: “Science defends itself against the Skeptical Environmentalist.”
Really. Science has to defend itself? Is this what we have come to? When Lomborg asked for space to rebut his critics, he was given only a page and a half. When he said it wasn’t enough, he put the critics’ essays on his web page and answered them in detail.
Scientific American threatened copyright infringement and made him take the pages down. Further attacks since, have made it clear what is going on. Lomborg is charged with heresy. That’s why none of his critics needs to substantiate their attacks in any detail. That’s why the facts don’t matter.
That’s why they can attack him in the most vicious personal terms. He’s a heretic. Of course, any scientist can be charged as Galileo was charged. I just never thought I’d see the Scientific American in the role of Mother Church.
Is this what science has become? I hope not. But it is what it will become, unless there is a concerted effort by leading scientists to aggressively separate science from policy.
The late Philip Handler, former president of the National Academy of Sciences, said that “Scientists best serve public policy by living within the ethics of science, not those of politics. If the scientific community will not unfrock the charlatans, the public will not discern the difference– science and the nation will suffer.”
Personally, I don’t worry about the nation. But I do worry about science.

Thanks for proving my point, Brendan. Once again you fail to respond in a substantive way and persist in being snotty. That’s the trademark of someone who knows the facts are not on his side.

“Nonsense. The history of science is a story of gradual shifts toward consensus on a variety of subjects. The work of science has *everything* to do with consensus.”
Dave,
First, so we can be on the same page, this is the dictionary definition of consensus:
____________________________________________
“Main Entry: con•sen•sus
Pronunciation: \kən-ˈsen(t)-səs\
Function: noun
Usage: often attributive
Etymology: Latin, from consentire
Date: 1843
1 a : general agreement : UNANIMITY b : the judgment arrived at by most of those concerned
2 : group solidarity in sentiment and belief
usage – The phrase consensus of opinion, which is not actually redundant (see sense 1a; the sense that takes the phrase is slightly older), has been so often claimed to be a redundancy that many writers avoid it. You are safe in using consensus alone when it is clear you mean consensus of opinion, and most writers in fact do so.”
___________________________________________
Please note that consensus is about “judgment, “opinion”, “sentiment” and “belief”. Why you ask? Because, consensus does not deal with FACTS. If something is indisputably factually true (The earth goes around the Sun, not the other way around) then consensus becomes superfluous, redundant and unnecessary. Agreed?
OK! Now to your comment:
“Nonsense. The history of science is a story of gradual shifts toward consensus on a variety of subjects. The work of science has *everything* to do with consensus.”
Where did you get this notion? What do you base this statement on? You have it completely backwards. I for one had formal education in the history and philosophy of science. When you study the history of science, the first thing you have to look at is the evolution of the concept of PROOF. The Greeks were very good at this and refined the concept to mean irrefutable, factual evidence as perceived from the physical world, mathematics and geometry. Note I used the word “perceived” because as philosophers were quick to point out the the only thing you could prove is “I think, therefore I am”, and so the word needs to be in there.
However, once this PROOF concept became accepted, science (with a great deal of hardship and persecution) became the tool of choice for dispelling myths, beliefs, opinions and sentiments. And of course, based on the definition above, you can shrink all of those words down to two: dispelling CONSENSUS. The history of science is filled with examples of this. I’ll give you one – Ptolemy and Copernicus. If you need more then, in the words of the “great” Phil Jones, go find them yourself :).
So you see, consensus has only one use in science – TARGET PRACTICE.

Frank Lee Mei Dere: “I’ve never heard anyone argue that the earth is round by saying that there is a consensus concerning it.”
I am not making that argument. Consensus in science is based on the scientific evidence.
You’re not making that argument?! That’s exactly the argument you’re making. You just got finished making it! I’m freaking’ quoting you, for crying out loud.
Let’s review the bidding — as simply and clearly as possible.
Bruce Cobb said, “There is an overwhelming scientific consensus that the earth is spherical, not flat. Yet, you don’t hear any scientists or others saying that.”
You directly answered him by saying, “That’s because the shape of the earth is long established and accepted.” In other words, if there were people arguing against it, then the proper way to win them over is by pointing to a “communicate the consensus view.”
Likewise, you consider that belief in AGW is warranted because of a supposed consensus concerning it, and that the proper way to answer critics is by pointing to a supposed consensus.
And when I (and others) point out that “consensus” is not a valid argument, you pull the AGW crap of weasel-wording out of it by saying “I never said that.”
My hair is thinning. I really don’t want to risk losing what little I have left by pulling it out in a pointless argument with someone who can’t even stick to the argument, and who claims he never said things he just got finished saying.
However, once more — consensus is not a scientific argument:
(1) If the evidence for something is strong enough to have created a true consensus among scientists, then it is strong enough to present as evidence on its own. You don’t tell people you’re right because of the consensus, but because of the evidence. (That’s kind of the idea of evidence, as I try to get across to my students.)
(2) If someone opposes AGW by presenting counter evidence (which is done at WUWT on a continuous basis), then you argue against it by showing the error of the counter evidence, not by claiming a consensus.
(3) And also — when lists can be made of thousands of scientists who do not agree with the consensus — there is no consensus to begin with.
Claiming consensus is not an argument: it’s a refusal to engage in argument.
Saying that you have not said something when what you’ve said is on record is not an argument: it’s just plain dishonest.
Although, it does seem to work on a depressingly frequent basis.
Darn, I guess you can’t post graphics in the comments. Anyhow, I ended my last post with this cartoon:

Bruce Cobb: “A claimed “consensus” is not scientific evidence.”
I agree. The consensus itself is not science, but is based on the science. I don’t think it is a red herring, though. It’s a necessary feature of science, as I pointed out above.
Frank Lee Mei Dere: “Let’s review the bidding — as simply and clearly as possible.”
Bruce Cobb said, “There is an overwhelming scientific consensus that the earth is spherical, not flat. Yet, you don’t hear any scientists or others saying that.”
You directly answered him by saying, “That’s because the shape of the earth is long established and accepted.” In other words, if there were people arguing against it, then the proper way to win them over is by pointing to a “communicate the consensus view.”
No. My comment directly follows: “Yet, you don’t hear any scientists or others saying that.”
So my argument is: “Yet, you don’t hear any scientists or others saying that (ie emphasising consensus) because the shape of the earth is long established and accepted (ie there is no need to emphasise concensus).”
My comment was about communication, not about establishing the science.
“Likewise, you consider that belief in AGW is warranted because of a supposed consensus concerning it…”
The consensus is a result of the science, not vice versa.
“However, once more — consensus is not a scientific argument:”
Agreed.
“(1)…You don’t tell people you’re right because of the consensus, but because of the evidence.”
As I say, it’s a way of communicating, in this case agreement about the science.
“(2) If someone opposes AGW by presenting counter evidence (which is done at WUWT on a continuous basis), then you argue against it by showing the error of the counter evidence, not by claiming a consensus.”
If appropriate yes, keeping in mind that climate science is complex, while time is often short.
“(3) And also — when lists can be made of thousands of scientists who do not agree with the consensus — there is no consensus to begin with.”
Consensus is general agreement, not unanimity.

Yes — and by corollary, when something is not “long established and accepted,” you are suggesting that the appropriate response is to “emphasise consensus.” Right? You can see how the logic follows there, can’t you? Please.
Geeze.
My comment was about communication, not about establishing the science.
And therein you have just stated the problem skeptics have with the warmists — skeptics raise issues with the science, while the warmists respond with issues of “communication.”
I’ve seen this repeatedly over the years — in fact it was one of the biggest reasons I started doubting the status quo position on global warming in the first place: any time an argument was brought up against it, the warmists fell back on “consensus.” I’d be looking for some good, solid science, and they gave me “consensus.” That raises red flags. Lots and lots of red flags.
The skeptics answered with data. Information. Analysis. In other words, “science.”
Stop it! Stop with the “communicating” and the “message” and just answer the damned objections.
Consensus doesn’t mean anything. Especially from a group who insists that they have a consensus for their position while at the same time publishing lists of all those who disagree with it.
Brendan H does not understand even the simplest formula:
Science ≠ consensus
There is no logical or quantifiable relationship between the two. None.
But when “consensus” is all you’ve got, then you only have two choices:
Go with the consensus argument. Or quit digging.

Sorry, but after reading your posts I’m afraid that your diatribe (as in prolonged discourse) deals with sociology, not with science. Not surprisingly, consensus is in fact sociological. Look up consensus and sociology.
And by the by, consensus does mean Unanimity. see my post at:

It’s sad when someone tries to rewrite history. I’ll be happy to see the rest of the story once its ferreted out.
Much has already been said above about the definition and the uses and abuses of ‘consensus’. Obviously there are varying degrees of agreement and disagreement in all fields of science, and failing to toe the current orthodoxy in many fields can lead to ostracism and worse (just ask graduate students today who utter an heretical opinion on AGW). But ultimately any ‘consensus’ in science is ideally subject to the pitfalls of empirical verification. The great danger is when, for political or ideological reasons, the current received consensus in a given field becomes immune from real scrutiny and falsification, which for science to operate properly must take place constantly. That’s clearly happened in climatology.
Dave H’s examples have more to do with established paradigms (in Kuhn’s sense), which of course represent a consensus of views as well, and remain current so long as their well-established theoretical structures continue to generate new discoveries and insights. It would be premature in the extreme to conclude that contemporary ‘climate science’ represents any kind of paradigm; it is at best a collection of hypotheses and speculations, which have become fashionable because of immense institutional support for political and ideological reasons, which in turn have led to government funding out of all proportion to their epistemological significance.
/Mr Lynn
OK, Brendan H, since I’ve apparently pushed the envelope a bit, I will strive to keep things nice and sparkling clear:
You say “The consensus is a result of the science, not vice versa.”
The point I and others have been making, including Michael Crichton in the first instance, is that consensus is NEVER a scientific argument. Invoking consensus, no matter what you are talking about, is not a scientifically valid argument. If the “consensus” is supported by data, then you discuss the data. It’s not necessary to talk about consensus if the data are sufficient. As I have pointed out, Crichton provides many salient examples of situations wherein the “consensus” of the day was wrong. Instead of mustering an argument in which the data support your point of view, you have played semantic games with the word “consensus”. I invite you to set forth a set of data that will show that the current climatic conditions on our planet are unprecedented. That is the fundamental argument of AGW: we are experiencing something that has never happened before in the natural history of the planet. If that proposition is not true, then discussions of causation are mere quibbling. So, please state your case: the temperature conditions (trend and magnitude) over the past several decades have never before existed on this planet. Here are the data that show this. Saying that Phil Johnson and Michael Mann think so is not an argument. Show the data, show where they came from, and make your case.
Sorry, should have said “Phil Jones”. I regret the error.
Frank Lee MeiDere: “Yes — and by corollary, when something is not “long established and accepted,” you are suggesting that the appropriate response is to “emphasise consensus.”
That depends on the context. At July 9, 2010 at 5:58 pm I provided several reasons why consensus is an important part of science, and I think it is legitimate to use it in these cases.
An additional reason would be for public policy purposes, where by necessity decision-makers need clear informatiion on which to act. Vaccination policy would be one such area. I think global warming is another.
“…I’d be looking for some good, solid science, and they gave me “consensus.””
I cannot verify your experience, but in my experience I have seen many climate debates on blogs where the warming proponents offer plenty in the way of arguments and evidence.
Smokey: “Science ? consensus
There is no logical or quantifiable relationship between the two.”
One is an outcome of the other. You have the sequence correct, anyway.
Jose Suro: “Sorry, but after reading your posts I’m afraid that your diatribe…consensus does mean Unanimity.”
I don’t accept that my writing constitutes a “diatribe”, and consensus can also mean “general agreement”, which does not involve unanimity and nor does it demand agreement on every last detail. So there is still room for disagreement within a consensus.
Robert Kral : “The point I and others have been making, including Michael Crichton in the first instance, is that consensus is NEVER a scientific argument.”
A consensus is a statement about the science, in the way that a summary report is a statement about a subject. So in that sense, of course, a scientific consensus is not a specifically scientific argument, but it is a reference to, and dependent on, a body of scientific knowledge and judgements.
Therefore, a consensus is as good or bad as the science it depends on.
“It’s not necessary to talk about consensus if the data are sufficient.”
Except that for most people, “the data” on climate science, and its importance and relevance, is not self-explanatory.
“I invite you to set forth a set of data that will show that the current climatic conditions on our planet are unprecedented.”
I’m not sure that the correct understanding is so much “unprecedented” as “anthropogenic”, but there are people who have a much better understanding of climate than I do. I could point you to some references if you wish.
“So, please state your case…”
My “case” on this thread is that consensus is a necessary component of science. This is not an issue of semantics, but a very important issue of information transmission in a complex society, ie, what and who do you believe, and why?
Since human beings are finite, we do not have the time or ability to become expert in every field, whether it’s law, medicine, science, music etc. Even within these categories, no one person can master more than a fraction of the subject matter.
Therefore, we need some means to sift the information available. One means is to identify the views of the experts in the field to gain their general understanding of that field, ie a consensus.
Anthony,
You are a breath of fresh air in the cesspit of modern “science”.
I worked for NASA on the Mars Exploration Team and my project was to make estimates of the chance of catastrophic damage from asteriods striking the proposed manned spacecraft. With the limited data at the time, I did manage to come up with a figure (with wide error bar!). My prediction was for a greater than 5% probability.
I presented my report to my boss. As he read it, his smile slowly turned into a deep frown. “John, I think you had better re-work the numbers, if you catch my drift”. That was code for “Congress and my bosses won’t like this, and we need to keep the funding going”. That was in 1971.
We had the Age of Reason in the 16th/17th Century, the Age of Industrialism in the 19th Century, the Age of Electronics in the 20th Century. Are we to revert to the Dark Ages once more? With economic devastation looming, the signs are not good.
That’s appalling, but not surprising. It was this kind of failure to heed engineering warnings in favor of a desire to please political masters that led to the Challenger disaster. It happens in every organization, unless controlled by courageous managers who aren’t afraid to get fired for speaking the truth.
With the increase in our knowledge since 1971, I wonder what your calculation would show today. Some of us still want the USA to go to Mars, despite the risks.
Which reminds me (sort of off-topic, but worth noting—I already added it to Tips) of a wonderful essay by Mars Society founder Robert Zubrin in Commentary for June 2010 entitled “Wrecking NASA: America’s most wondrous and daring enterprise now points in a new direction—inward.”
Dr. Zubrin contrasts the “open-future” philosophy of the original NASA with the “closed-future” mentality championed by the Obama administration, particularly John Holdren. The “closed-future” is “based on the doctrine of limited resources. . . There isn’t enough of x to go around . . . therefore human aspirations must be suppressed.”
Given the “closed-future” ethos of today, Mr. Burford’s boss would doubtless err on the negative side: “Better make the chances of a catastrophic encounter even greater, so we can spend our money here on Earth and not worry about going to Mars.”
/Mr Lynn
Mr. Burford reports being told “John, I think you had better re-work the numbers, if you catch my drift,” in 1971.
Mr. Lynn suggests that that kind of thinking led to the Challenger disaster; but the US was not alone in the correction of disagreeable data. Forty or more years ago the Soviets were ahead of us in that field, and pushed through to advances that would have been impossible if politics had not ruled over science. In 1960, for example, not only did they bravely continue in their understanding that Lysenko’s methods triumphed over Mendel’s genetics, but they demonstrated the success of Soviet rocketry in the testing and launch of the R-16 ICBM at Baikonur on 24 October 1960.
Unfortunately, the second stage of the rocket fired before the first stage. Look up the Nedelin disaster. It seems that any data suggesting the rocket was not ready for launch were swept aside during final testing. The entire event, unlike the Challenger, was hidden for nearly 30 years.
Yes, that was just a rocket, and only 100 people were toasted, and global warming is so much more important, and so many more will be toasted.
But as I asked before (please, Mr. H and Mr. H), where is the data? The uncorrected data? Please don’t tell me that I already have it, or that someone else has already seen it. Where is it?

You are simply using the logical fallacy of “argument by authority”. You choose to simply believe the so-called experts, probably because it is line with your world-view. But, perhaps it is just intellectual laziness on your part. There is another way, though. It’s called using your brain.
You should try it sometime.
Bruce Cobb: “But, perhaps it is just intellectual laziness on your part.”
Bruce, an insult is not an argument, and nor is argument by authority a logical fallacy when the authority is genuine.
