Science: A Danger for Public Policy?!

Posted by Henry Bauer on 2017/02/08

Public policies rely on advice and consent from science about an ever wider range of issues (environmental challenges, individual and public health. infrastructure and its safety, military systems). Surely this is unquestionably good, that public policies are increasingly pragmatic through respecting the facts delivered by science?

No. Not necessarily, not always.

The central problem is that science — humankind’s understanding of nature, of the world — doesn’t just deliver facts. Science is perpetually incomplete. On any given question it may not be unequivocal.

The media, the public, policy makers, the legal system all presume that a contemporary consensus in the scientific community can be safely accepted as true for all practical purposes. The trouble is that any contemporary scientific consensus may later prove to have been wrong.

If this assertion seems outlandish —theoretically possible but so unlikely as to be ignorable in practice — it is because the actual history and nature of science are not widely enough understood.

The contemporary scientific consensus has in fact been wrong about many, perhaps even most of the greatest advances in science: Planck and quantums, Wegener and drifting continents, Mendel and quantitative genetic heredity; the scientific consensus and 1976   Nobel Prize for discovering the viral cause of mad-cow diseases was wrong; that stomach ulcers are caused by bacteria had been pooh-poohed by the mainstream consensus for some two decades before adherents of the consensus were willing to examine the evidence and then award a Nobel Prize in 2005.

Historical instances of a mistaken scientific consensus being have seemingly not affected major public policies in catastrophic ways, although one possible precedent for such unhappy influence may be the consensus that supported the eugenics movement around the 1920s, resulting in enforced sterilization of tens of thousands of people in the USA as recently as the latter half of the 20th century.

Nowadays, though, the influence of science is so pervasive that the danger has become quite tangible that major public policies might be based on a scientific consensus that is at best doubtfully valid and at worst demonstrably wrong.

The possibility that significant public actions might be dictated by an unproven scientific consensus was explicitly articulated by President Eisenhower. His warning against the potential influence of the military-industrial complex is quite often cited, but little cited is another warning he gave in the same speech:

“in holding scientific research and discovery in respect, as we should, we must also be alert to the equal and opposite danger that public policy could itself become the captive of a scientific-technological elite.”

That can happen when a contemporary scientific consensus is accepted as practical truth, as settled science. The crucial distinction could hardly be explained more clearly than Michael Crichton did in an invited lecture at CalTech:

“Consensus is invoked only in situations where the science is not solid enough. Nobody says the consensus of scientists agrees that E=mc2. . . . It would never occur to anyone to speak that way.”

Crichton had in mind the present-day scientific consensus that human-caused generation of carbon dioxide is chiefly responsible for rising global temperatures and associated major climate-change. The fact that there are highly competent public dissenters — including such winners of Nobel Prizes as Ivar Giaever (Physics 1973), Robert Laughlin (Physics 1998), Kary Mullis (Chemistry 1993) — demonstrates that human-caused global warming is a consensus, not the unanimity associated with such “settled science” as the Periodic Table of the chemical elements or that E=mc2.

The proponents of human-caused global warming constitute an effective elite. Since they represent the contemporary consensus, they largely control peer review, research funding, and which research gets published; and they hold important positions in the halls of power of individual nations as well as in such international organizations as the Intergovernmental Panel on Climate Change.

The history of science is unequivocal: Contemporary scientific consensuses have been wrong on some of the most significant issues. Those who determine public policies would do well to seek an impartial comparison and analysis of the substantive claims made both by proponents of a mainstream consensus and by those who claim that the evidence does not prove that consensus to be unquestionably correct.

In absence of an impartial comparative analysis, public discourse and public actions are determined by ideology and not by evidence. “Liberals” assert that the mainstream consensus on global warming equals “science” and anyone who properly respects the environment is supposed to accept this scientific consensus. On the other side, many “conservatives” beg to differ, as when Senator Inhofe flourishes a snowball. One doubts that most proponents of either side could give an accurate summary of the pertinent evidence. That is not a very good way to discuss or to make public policy.


This little essay had been offered as an Op-Ed to the Wall Street Journal, the New York Times. the Washington Post, the Los Angeles Times, the Financial Times (London), and USA Today. That it appears here confirms that none of those media stalwarts wanted to use it.

Trust science at your peril: Beware of scientism and political correctness

Posted by Henry Bauer on 2016/06/25

Science is, ideally, a quest for authentic understanding of the world, of everything in the universe. Scientism is a religious faith which preaches that only science is capable of gaining such authentic understanding and that contemporary scientific claims are for all practical purposes true.

In reality, science is a perpetually unfinished quest. The history of science tells of false trails followed, of errors made, of misguided theories held dogmatically long after the evidence had turned against them, of researchers motivated by self-interest and influenced — corrupted, in a sense — by conflicts of interest.

Science has progressed marvelously, but the progress has not come steadily and linearly, it has come through continual correction of minor errors as well as periodic scientific revolutions in which former dogmas were discarded and replaced by different theories, different beliefs, different dogmas, sometimes to an extent capable of changing world-views.

Those realities have been described and documented in many articles and books over many decades (1), yet the conventional wisdom seems ignorant of them. In the popular view, science deploys the scientific method which guarantees getting things right through scrupulous adherence to facts, so that the scientific consensus on any given topic at any given time can supposedly be relied on quite safely to guide personal and public actions.

People who question the mainstream view, the official positions disseminated by such bodies as the National Academy, the Royal Society of London, the National Science Foundation, the National Institutes of Health, the Food and Drug Administration, the World Health Organization, etc., are dismissed as ignoramuses on a par with those who still believe that the Earth is flat, and they are denigrated, attacked, and suppressed as “denialists” — for example, the eminently qualified scientists who question whether HIV really causes AIDS (2), or whether carbon dioxide is the prime cause of global warming (3), or whether the universe began in a Big Bang about 13 billion years ago (4).

In other words, the officially accepted conventional wisdom functions as an exercise of scientism, proclaiming as true — as not to be questioned — any contemporary claims that have the imprimatur of a prevailing scientific consensus.

The most common popular, mass-media-disseminated beliefs about science fall in line with the official scientistic conventional wisdom. Prominent popularizers of the scientistic faith include people sometimes described as the “New Atheists” — see for instance Curtis White in The Science Delusion (Melville House, 2014), who names among others Richard Dawkins, Daniel Dennett, Sam Harris, Bill Mahler. Self-styled “Skeptics” (for instance Michael Shermer and the late Martin Gardner) are also apostles of scientism, as illustrated in associated publications (Skeptic, Skeptical Inquirer).

But promiscuously indiscriminate faith in currently accepted scientific knowledge is unwarranted. One does not need the immense scholarly literature (1) to recognize that, it is already obvious from first principles and fundamental logic:

–>      Science is carried out by human beings and is therefore inherently fallible.

–>      Scientific theories are neither uniquely determined nor proved by any amount of factual evidence. The proverbial black swans demonstrate that no matter how comprehensive or long-standing any given body of evidence and associated explanations may be, no matter that an hypothesis may have been thoroughly tested and accepted via the scientific method, there may remain lurking in the unknown unknown some bits of data that can disprove the accepted theory instantly and devastatingly.

The popular adherence to scientistic dogmas is immensely dangerous because it may support public policies that cause tangible damage, sometimes on a large scale. Historical examples are fairly well known, but their lesson has not been learned; perhaps because a corollary of contemporary scientistic faith seems to be the notion, implicit if not explicit, that even if science was fallible in earlier times, today’s science is so advanced, so sophisticated, that it is no longer dangerously fallible. That and similar corollaries are acts of faith unsupported by evidence, thereby confirming that scientism is a quasi-religious faith: it is unshakeable, embraced as absolutely and self-evidently true.

A couple of recent books (5) describe the considerable damage done by public policies based on a scientific consensus which remained active during something like half of the 20th century: the policies of forced sterilization of purportedly feeble-minded individuals. This was an exercise in eugenics, a program intended to improve the national genetic stock, and it was supported and justified by the prevailing scientific consensus.

In reviewing these books, David Oshinsky focuses on the Supreme Court’s 8-to-1 decision in 1927, written by the revered Oliver Wendell Holmes Jr. and agreed to by the “liberal” Jewish Louis Brandeis as well as by 6 other Associate Justices, upholding the forced sterilization of those judged to be mentally defective: “Was it an isolated misstep or something more: an indictment of Justice Holmes and the Progressive movement he appeared to embrace?” (6).

Oshinsky describes the IMBECILES book by Cohen as “a superb history of eugenics in America, from its beginnings as an offshoot of social Darwinism — human survival of the fittest — to its rise as a popular movement, advocating the state-sponsored sterilization of ‘feeble­minded, insane, epileptic, inebriate, criminalistic and other degenerate persons’.”

The point I want to make here is that the forced sterilization of tens of thousands of Americans, which continued in some States into the 1960s, is nowadays described as an outrage based on pseudo-science, yet it had relied on what was regarded at the time as perfectly sound science supported fervently by individuals whose reputation remains that of progressive reformers: as well as Justices Holmes and Brandeis, strong advocates of this eugenic program included other “progressive icons like Theodore Roosevelt and the birth control champion Margaret Sanger . . . . people who combined ‘extravagant faith in science and the state with an outsized confidence in their own expertise.’ . . . Science didn’t lie” (6).

This notion that science doesn’t lie, that it can always be believed, is a tenet of scientism, and it is baseless, quite wrong, as already noted. Yet this notion, this subconscious scientism continues to corrupt public discourse. Scientism is a faith held unwittingly by most popular media, including such elites as the New York Times; and it is held, again unwittingly, by today’s sociopolitical progressives or liberals.

When some claims by some scientists seem plausibly consistent with liberal, progressive programs, activists seize on them, make dogmas of the claims, and denigrate and attack those who disagree as unscientific denialists.

This circumstance is what has come to be called in recent decades “political correctness”: certain views are to be accepted as so self-evidently correct, objectively true — and by the way ethically and morally sound — that disagreeing with them is virtually a criminal act; and indeed actions that are politically incorrect may bring sanctions. Contemporary illustrations of such sanctions are the penalties imposed by colleges and universities on students and faculty who make politically incorrect statements, including the mere use of a word or a phrase that acts as a “trigger”, a “micro-aggression” that makes some individual belonging to a certified-discriminated-against minority feel uncomfortable (7).

That something is politically correct is shown when people who have no direct specific knowledge about a topic express with certainty a dogmatic opinion about it. They have obviously taken this opinion on faith, from sources congenial to them on ideological grounds, which may be based religiously, socially, politically — at any rate, not on actual evidence about the matter.

Contemporary scientific claims that have attained the status of politically correct include that HIV causes AIDS and that human-caused liberation of carbon dioxide is the prime cause of climate change. The manner in which media and individuals refer to these matters is an immediate proof that opinions about them are politically correct, not evidence-based.

For example, the vigilantes who most assiduously and viciously attack those who question whether HIV causes AIDS include an economist (Nicoli Nattrass), a graduate student (Ken Witwer), a psychologist (Seth Kalichman), a lawyer (Jeanne Bergman), an activist (Nathan Geffen) and others, all of whom feel qualified, despite their lack of appropriate qualifications, to denigrate eminent molecular biologists with deep knowledge of the subject, and even to demand that the National Library of Medicine remove a journal from MEDLINE (8).

Left-leaning media (say, MSNBC) treat HIV=AIDS as indisputable settled science; right-leaning media (say, Fox News) doubt that HIV causes AIDS.

Left-leaning media treat as indisputably settled science that human activities are responsible for global warming and climate change; right-leaning media doubt or deny that.

Nature, however, will not be mocked, and the truth is not determined by human ideologies. Public policies (and also private actions, of course) had best be based on the soundest, most probing and skeptical assessment of current knowledge-claims in light of the indisputable fact that no contemporary scientific consensus represents guaranteed truth.

If the present scientistic, politically correct beliefs about HIV/AIDS and about climate change are as misguided as were the scientistic, politically correct beliefs about mental deficiency and eugenics, then immense harm is being done and will continue to be done. Unfortunately, the plain evidence is that HIV does not cause AIDS (9, 10), and the notion that human activities are responsible for global warming and climate change is suggested only by highly complicated, sophisticated, and fallible computer programs that have already been wrong about the global cooling in the 1940s to 1970s and the lack of appreciable warming since about 2000 (4).

Forced sterilization as part of a eugenic program to improve the fitness of the population was supported by progressive reformers and by eminent medical and scientific experts. That physical traits are transmitted from one generation to another was known, scientifically as well as popularly. That behavioral characteristics are similarly transmitted was not obviously wrong, and when sanctioned by experts it became the conventional wisdom. So feeble-minded-ness, epilepsy, poverty, criminality and other socially undesirable characteristics came to be targets for elimination, by quarantining or sterilizing people and families where such characteristics had been noted (11). There was not sufficient dissent within expert communities to prevent what is now recognized as pseudo-science from becoming accepted as settled science, during the early decades of the 20th century: “Less than 100 years ago, America’s finest minds were convinced the nation was threatened by sexually insatiable female morons” (12). Those finest minds included, as well as the earlier mentioned progressive reformers, David Starr Jordan, a biologist specializing in ichthyology, an activist for peace, an eminent educator — president of Indiana University and later founding president of Stanford University — and moreover so concerned with distinguishing good science from bad science and pseudo-science that he had written a book about it (13), as well as works about eugenics (14).

So policy makers might be excused for succumbing to the “scientific” evidence supporting eugenics — a century ago. Nowadays, though, there is no similar excuse for sticking with the theory of HIV/AIDS or with the claim that it is indisputably settled science that global warming and climate change are humanly caused. Competent, qualified experts have published and spoken copiously, pointing to the deficiencies of the present scientific consensuses on these matters. It is past time that these whistle-blowers, these “denialists”, be attended to; that the actual evidence be attended to.

What is scientific literacy good for?

Posted by Henry Bauer on 2016/01/03

The way scientific literacy is defined and measured makes no sense — see Scientific Literacy and Myth of the Scientific Method (1992/1994 and still in print, which surely says something about the validity of its arguments).
Scientific literacy is measured by what people know about things like atoms and about “the scientific method”, in effect by how well they could function within science; whereas scientific literacy should surely mean what non-scientists need to know about the role of science in society: when to believe the experts and when not to. About medicine, by analogy, we don’t need to know how drugs work, say, we just need to know where to find data about how long they have been in use and what their side effects are and whether there’s already a law suit against the manufacturer that is still actively advertising it (quite a common circumstance; see anticoagulants Pradaxa and Xarelto and anti-diabetes Invokana at the moment (2015-16).

It turns out that current measurements of scientific literacy yield results that should be highly embarrassing to the expert gurus on this topic.

For example, people who score high on “scientific literacy” do poorly on distinguishing pseudo-science from science — Chris Impey, Sanlyn Buxner, Jessie Antonellis, Elizabeth Johnson, & Courtney King, “A twenty-year survey of science literacy among college undergraduates”, Journal of College Science Teaching, 40 (#4, 2011) 31-7.

When it comes to human-caused climate change, perhaps the measures of “scientific literacy” are pretty meaningful after all, because the most scientifically literate according to these tests are least likely to believe that human generation of carbon dioxide is responsible for climate change:
“Climate skepticism not rooted in science illiteracy: Cultural values, not knowledge, shape global warming views, a study finds” (Janet Raloff, 29 May 2012)

“New study: Numerical and Science Literacy cause Climate Change Skepticism” (1 June 2012)”

“Study: Climate skeptics and proponents score highest on climate science literacy…but are the most polarized” (Anthony Watts, 23 February 2015)

As I had pointed out in the first entry on this blog (A politically liberal global-warming skeptic?), most people’s views about human-caused climate change are determined by their political affiliation and not by their understanding of science or familiarity with the evidence.

Who can be trusted about science? Not the Royal Society of London or the National Academy of the United States

Posted by Henry Bauer on 2016/01/01

An earlier post (Mainstream propaganda by the BBC about denialism and global warming) described a BBC television documentary in which the President of the Royal Society of London presided over a thoroughly misleading piece of propaganda seeking to entrench mainstream dogma about human-caused climate change, HIV as the cause of AIDS, and the claimed safety of genetically modified foods and plants.

The merest smattering of knowledge of the history of science and a smidgeon of common sense ought to suffice to demonstrate that the mainstream dogma is unwarranted on all three of those issue, incidentally:

1. Human-caused climate change: There is simply no proof on offer. The dogma is based on the banality that carbon dioxide gas absorbs infrared radiation, and that global temperatures overall have been rising in the last 150 years or so at the same time as industrial development has increasingly generated carbon dioxide.
But global temperatures actually cooled from the 1940s to the 1970s while CO2 was increasing, and temperatures have remained steady since about 2000 while, again, CO2 continued to increase. QED.

2. HIV and AIDS. HIV is held responsible for an epidemic of AIDS spread chiefly through sexual intercourse.
The website of the National Institutes of Health reports the apparent transmissibility of HIV as 8 per 10,000 acts of unprotected intercourse, from male to female; transmissibility from female o male is half of that, 4 per 10,000. Any epidemic requires that each infected individual pass the infection on to more than one other person in a short space of time. Transmissibility of less than 1 per 1000 is entirely incapable of generating an epidemic.
For comparison, transmissibility of known sexually transmitted diseases is not far from 1 in 2 (for chlamydia, gonorrhea, herpes, syphilis).

3. All the conceivable possible dangers of genetically modified organisms and their products cannot possibly be known or measured. No matter how much data accumulates, the unknown unknown may at any time deliver a black swan to confound all the scientific predictions and assurances. Half a century ago Alvin Weinberg pointed that out with respect to the safety of nuclear reactors. “Science” of course declared them safe, in other words Chernobyl, Three-Mile Island, and Fukushima could not possibly have occurred. For what Wikipedia is worth, it lists 99 significant accidents in all.

But back to the Royal Society and human-caused climate change.

Andrew Montford has described in full detail how the Royal Society of London has been a proselytizer of human-caused climate change since at least 1989, under three successive Presidents and contrary to the Society’s proper role, which is to stick to science and leave politics and policy to others; see Nullius in Verba: On the Word of No One — The Royal Society and Climate Change.

The Royal Society pamphlet, A SHORT GUIDE TO climate science,  poses 20 questions and gives a one-paragraph pot-boiler answer to each, for example

“1. Is the climate warming?
Yes. Earth’s average surface air temperature has increased by about 0.8 °C (1.4 °F) since 1900, with much of this increase taking place since the mid-1970s. A wide range of other observations such as sea-level rise, reduced Arctic sea ice extent and increased ocean heat content provide
incontrovertible evidence of a warming Earth.”

These one-paragraph mind-bites are expanded in Climate Change: Evidence, Impacts, and Choices (NatAcadPress2012-14673), published jointly by the Royal Society of London and the National Academy of science of the United States. The questions are the same but worded differently, for example the first is not “Is the climate warming?” but “How do we know that Earth has warmed?”.
That small change has a rhetorical significance that is far from small: the question is no longer treated as open, it is declared to have been settled.

All those answers are misleading in some way, however, and they have been thoroughly debunked in THE SMALL PRINT: What the Royal Society Left Out.

In response to question 1 and its answer, for example:
“A fuller picture: This is hardly an important question. The Earth’s surface is always warming or cooling, or on some occasions barely changing. What is important is that the change referred to is small and imperfectly measured. It should also be stressed that the Royal Society guide does not mention the role of the time window they are using for comparison. The climate has cooled since the mid-Holocene climatic optimum 8,000 years ago, and the warming of the past few decades is relatively small in comparison.
Surface temperatures have increased on average by about 0.8°C since 1900. There was a rise of around 0.5°C at the start of the twentieth century, followed by a small fall from 1940 to 1970. From then until the late 1990s temperatures rose by around 0.5°C. Differences of a tenth of a degree are insignificant. The temperature is virtually unchanged from that at the beginning of the century. The two periods of increase are indistinguishable, although the earlier increase cannot be attributed to increased carbon dioxide.
The relation of other observations such as sea-level rise, Arctic sea ice extent and ocean heat content all depend on more factors than global mean temperature, and are hardly incontrovertible evidence of warming. That said, the possible acceleration of ocean heat content accumulation and sea level rise are close to the limits of our ability to detect and the values involved cannot be reconciled to each other. Depending on the time scale, other observational datasets are still more equivocal: global sea ice levels declined for several decades but are now above their long-term mean.”

In any case, on an even longer time-scale, that global temperatures are increasing is not in dispute, given that we are only about 15,000 years after a major Ice Age and it will likely be warming for about another 80,000-100,000 years or so before it cools again toward the next major Ice Age — there have been 7 or 8 such major Ice Ages in the last million years or so.

Only a couple of years after the Royal Society and National Academy had published Climate Change: Evidence, Impacts, and Choices, the same two bodies published Climate Change: Evidence and Causes (NatAcadPress2014-18730), which goes even further in declaring settled as fact that human generation of carbon dioxide has been primarily responsible for global warming. This last pamphlet is replete with rhetorical trickery, sins of omission and of commission, and is clearly propaganda, nothing like a cool scientific assessment of the evidence. My detailed critique of it has just been published in the Journal of Scientific Exploration: NAS-RS Review.

That the Royal Society and the National Academy are actively pushing to entrench as settled belief that human activities are producing climate change is evident from the way in which their publications have become increasingly one-sided, emphatic, and regrettably dishonest.

The political division over climate change

Posted by Henry Bauer on 2015/11/01

A friend sent me this link  to a report of Senator Ted Cruz showing himself to know more about science and facts associated with alleged global warming than does the chair of the Sierra Club.

Looking for coverage of this story from other viewpoints simply confirmed that The Left  has its own facts and theories and The Right  has its own different facts and theirs, as I remarked in the inaugural post on this blog, A politically liberal global-warming skeptic?

In my view, Cruz is right on the science in this case but quite wrong in his politics. So I seem able to keep my science and my politics separate — but then perhaps that is not the case on every issue?

Climate change “deniers”

Posted by Henry Bauer on 2015/10/16

Very good piece, “Climate change denier silenced for doing Climate Science and disagreeing with the science“.

“Philippe Verdier, weather chief at France Télévisions” is the lead in to the story, but it also cites Freeman Dyson, greatly respected physicist who for decades was at the Institute for Advanced Study in Princeton:
“‘It’s very sad that in this country, political opinion parted [people’s views on climate change],’ he said, in an interview with The Register. ‘I’m 100 percent Democrat myself, and I like Obama. But he took the wrong side on this issue, and the Republicans took the right side.'”

Precisely my view: “A politically liberal global-warming skeptic?”.

Psychological toll of climate-science belief

Posted by Henry Bauer on 2015/07/11

Mountainmere  just drew our attention to the devastating psychological impact of belief in human-caused climate change.

Esquire carried (7 July) a story by John Richardson, “When the End of Human Civilization Is Your Day Job: Among many climate scientists, gloom has set in. Things are worse than we think, but they can’t really talk about it” — they are afraid to talk about it because of “the relentless campaign against them” in which the poor folk are labeled “alarmist”. (The heartbreaking Richardson story was picked up in a number of places, for instance “Climate Scientists Are Dealing with Psychological Problems”  as well as the Judith Curry blog that mountainmere had cited, “Pre-traumatic stress syndrome: climate scientists speak out”.)
If climate “scientists” want to know what a relentless campaign really looks like, they should examine the treatment meted out to those “denialists” who draw attention to the lack of evidence to support the hypothesis of human-caused global warming.

Richardson’s featured climate-scientist victim, Jason Box, is a stereotypical ultra-environmentalist: an American who has worked for Greenpeace, demonstrated at the White House, claimed that sea levels would rise inevitably by 70 feet in the next few centuries, and “escaped America’s culture of climate-change denial” by moving from Ohio to Denmark. A report of methane seeping into Arctic sea-water so terrified Box that he immediately tweeted “If even a small fraction of Arctic sea floor carbon is released to the atmosphere, we’re f’d”, which naturally brought a flurry of headlines.
Box looks at the worst, and among the least likely, of the various scenarios generated by the computer models used by climate “scientists” — models that have been demonstrably wrong for the last 15-18 years or so during which there has been no warming while carbon dioxide levels have continued to rise; models that fail to account for the 1940s-to-1970s period when global temperatures were actually decreasing while carbon-dioxide levels were steadily rising.
Box thinks “most scientists must be burying overt recognition of the awful truths of climate change in a protective layer of denial (not the same kind of denial coming from conservatives, of course). I’m still amazed how few climatologists have taken an advocacy message to the streets, demonstrating for some policy action.”

Richardson’s story is full of errors, notably that “warming is tracking the rise of greenhouse gases exactly as their models predicted”. No. The models have not predicted the empirical fact that global temperatures have been stable rather than rising since about 2000; some reports even have it as a cooling rather than a slowing or halt in global average temperature:;;;;

Richardson describes the terrible stress that climate scientists are under for bringing their message of lack of hope: “targets of an unrelenting and well-organized attack that includes death threats, summonses from a hostile Congress, attempts to get them fired, legal harassment, and intrusive discovery demands so severe they had to start their own legal-defense fund, all amplified by a relentless propaganda campaign nakedly financed by the fossil-fuel companies”.
It’s just as well that they can continue to do their depressing work with the help of large grants and that any attempts to have them fired went nowhere; and that the “intrusive discovery demands” were no more than to ask for the raw data on which Michael Mann conjured his alarmist “hockey-stick” graph of unprecedented rate of warming — a graph that the Intergovernmental Panel on Climate Change dropped from its Reports because it was shown to be not a valid reorientation of the data. Professional scientific journals have increasingly being demanding that all data on which articles are based need to be made publicly available; it is not clear to me why climate “science” should be exempt. The only reason to keep data secret is to avoid that others could show that published analyses are flawed.
And those poor climate scientists suffered from having their e-mails hacked, revealing that they were deliberately fudging the evidence. (Google “Climategate” for details about that.)

So, anyway, those poor activist climate “scientists” are suffering gloom, sadness, fear, anger; “Dr. Lise Van Susteren, a practicing psychiatrist and graduate of Al Gore’s Inconvenient Truth slide-show training, calls this ‘pretraumatic’ stress.” Some are retreating off the grid to await the catastrophe. “No one has experienced that hostility more vividly than Michael Mann”, who barley manages to keep going as a well-paid tenured full professor at Penn State.

I urge you to read Richardson’s full story, especially the later parts that describe all the suffering that climate scientists endure.

For yet more insight, go to Judith Curry’s earlier blog post, “Pre-traumatic stress syndrome: Climate trauma survival tips”  which informs, among other things, about “the relatively new field of psychology of global warming”; followed by Curry’s sensible deconstruction of climate-change hysteria.

The unfortunate pre-traumatically stressed climate-“science” activists suffer quite unnecessarily. I recommend resort to the school of psychology, “rational-emotive therapy”, associated with the name of Albert Ellis; see his A New Guide to Rational Living, or Help yourself to happiness through rational self-counseling by Macie C. Maultsby, an acolyte of Ellis.
The essence of this approach is to list in writing one’s depressing thoughts, and then the emotions they arouse. Merely writing these down tends to reveal how out of all proportion the emotions are. Then, the really important part, annotate those depressing thoughts with the actual evidence.
With climate “scientists”, this should bring immediate relief, since all their depression arises only from computer models, whereas reality demonstrates that global warming is the result of the Earth recovering from the last Ice Age and that carbon dioxide has no appreciable effect, as proven by the periods from the 1940s to the 1970s and again since 2000, when “carbon” was being emitted relentlessly but Earth warmed not at all or even cooled.

Who looks at evidence? Almost no one

Posted by Henry Bauer on 2015/06/28

I’ve been a crank for a long time about Loch Ness Monsters, frustrated because I can’t get people to look at Tim Dinsdale’s 1960 film which shows quite clearly a huge animal swimming in Loch Ness, submerging while still throwing up a massive wake.

For more than a decade, I’ve been a crank about HIV not causing AIDS, frustrated because I can’t get people to look at the clear evidence that HIV tests don’t track something infectious, and that the numbers in plain sight on the website of the Centers for Disease Control & Prevention, rates of sexual transmission at less than 1 per 1000 acts of unprotected intercourse, mean that HIV cannot cause an epidemic.

Now I’ve become a crank about human-caused climate change, frustrated because people won’t look at the clear evidence that carbon dioxide has been increasing steadily even as the global temperature was level or dropping form the 1940s into the 1970s, when the experts were predicting an Ice Age; and as the global temperature has not increased since the end of the 1990s.

Why don’t people look at evidence?

Because, I’ve finally realized, they don’t want to risk having to change their mind. There is no positive incentive and plenty of negative incentive. It’s beyond cognitive dissonance, which is to evade the significance of evidence after having come across it. It’s obviously even better not to have come across the evidence at all.

On human-caused climate change (HCCC), disbelief is expressed loudly and publicly by “conservatives” (in my view more accurately described as reactionaries) who have that opinion for the wrong reasons, namely the belief that economic free markets are the most important thing and regulating anything is bad.

“Liberals” or “progressives”, on the other hand (who are actually not liberal or progressive but simply knee-jerk politically correct) don’t look at the evidence because they don’t need to, it’s of no interest to them, they would take their stance that humans cause environmental damage no matter what. And they maintain perfect deniability, they are blameless, they were just accepting what the authorities, the experts, have been saying loudly and incessantly.

Most of my family and friends treat my “reactionary” stance on HCCC as a minor flaw, allowing me space because I tend to get caught up in Quixotic stuff all the time. They have no interest in looking at the evidence because they are completely comfortable with the notion of HCCC because it fits their anti-reactionary political views — which I happen to share. If it turns out that this HCCC is mistaken, there would be all sorts of undesirable consequences, in particular that reactionary views might appear to have been vindicated.

I was distressed when Stephen Colbert took HCCC as proven. I am not happy when all the MSNBC crowd does so, but they’ve become too extreme for me anyway and I rarely watch. But I was very unhappy when Jon Stewart took HCCC as proven. And Pope Francis may have been the last straw (in the wind, as far as ever changing public opinion). Though I did get a sort of sardonic enjoyment from the pundits who pointed out that the Pope knew what he was talking about because he had been a chemist. And I am getting continuing Schadenfreude over the contortions of the Republican presidential candidates as they are forced to comment on the Pope’s encyclical.

Evidence-seeking, I realize, is an obsession of perhaps the tiniest minority there is. On the dangers of modern medical practice, there are just a few dozen voices crying out publicly in the wilderness. On HIV/AIDS, there is our Rethinking AIDS  group of some dozens of people, with a few thousand more quietly agreeing. On HCCC, there are a few academic types like myself who got here because of the evidence, and who subsist uncomfortably in the association with people whose political and social views we do not share, to put it mildly.

I’m beginning to accept that none of the items in my bucket list will see the light of an enlightened day within my lifetime: Nessie discovery, rejection of HIV=AIDS, rejection of carbon-dioxide-is-hurting-us.

But I do remain curious about how the “authorities” will adjust when reality eventually catches up with them irrevocably.

Freeman Dyson on climate change

Posted by Henry Bauer on 2015/05/13

Freeman Dyson is an eminent, widely honored and respected  physicist. In the New York Times Book Review of 19 April 2015, he says this:

On climate science, I recommend “Cool It: The Skeptical Environmentalist’s Guide to Global Warming,” by Bjørn Lomborg. . . . Lomborg is an economist .  . . . [and skeptic] with understanding and respect for the beliefs . . . [he is] questioning. The reason why climate science is controversial is that it is both a science and a religion. Belief is strong, even when scientific evidence is weak.”

Sea-Level-Rise Hysteria

Posted by Henry Bauer on 2015/01/15

Human-caused global warming, and even more terrifyingly human-caused climate change, is blamed for all sorts of things: more frequent and more extreme tornados and hurricanes and tsunamis, proliferation of viruses, shortage of fresh water, and of course rising sea levels that will submerge coastal cities. For example (from Reuters via Sydney Morning Herald):

“Sea level rise in the past two decades has accelerated faster than previously thought in a sign of climate change threatening coasts from Florida to Bangladesh, a study said on Wednesday. . . .

IPCC scenarios . . . range from a sea level rise of 28 to 98 cm this century . . . .

the rise has accelerated, with the most recent rates being the highest on record . . . .

Sea level rise is gnawing away at shores from Miami to Shanghai”.

All this is based on a letter, just published on-line by Nature, that used some mathematical techniques to re-evaluate, from admittedly incomplete data, what the sea-level rise actually was from 1901-1990; concluding that it was a bit less than formerly thought, at about 1.2 mm per year rather than 1.5 mm; and leapt to 3 mm per years in the last two decades. A terrifying acceleration!

Human activities apparently threaten us with between 28 cm (11 inches) and 98 cm (39 inches) in this century. That wide range of expectation should make obvious how uncertain these projections are; but what is altogether missing is an assessment of how this expectation compares with what one might expect from purely natural causes.

During the last Ice Age, which ended about 15,000 years ago, sea level was 400 feet lower than now. Quite naturally, sea level must rise as things warm up after the Ice Age and glaciers melt. But how rapidly?

On average, from purely natural causes, sea level has risen in the past, following an Ice Age, by about 5 inches per century. However, the rate varied tremendously during different eras; for example, pulses of as much as 100 inches per century for 5 centuries (Vivien Gornitz, “Sea level rise, after the ice melted and today”).

In other words, purely natural causes have in the past produced rates of sea-level rise considerably greater than the merchants of doom and gloom are now projecting as being caused by human actions, projecting on the basis of computer models that failed to predict the present decade-and-a-half lull in “global warming”.
