  • Why We Need More Climate Change Skeptics

    Climate scientists are not prophets. Those who believe them on faith provide no good service to the pursuit of truth.

    Those who blame climate change for every storm or forest fire are silly. Equally silly are those who claim that a particularly cold day proves that climate change is a farce.

    Fear of environmental calamity has caused human destruction before, such as when Rachel Carson’s book, Silent Spring, led to the banning of the pesticide DDT. As a result of the “success” of the environmentalist movement in banning DDT, an estimated 30-50 million people in Africa—mostly children—died from malaria carried by the renewed growth in the mosquito population. Malaria deaths increased from tens of thousands per year pre-ban to millions per year post-ban. The story was similar in India. These were preventable deaths that resulted from stoked fears.

    Now the target is carbon dioxide. We are told that 97 percent of climate scientists agree with their own scientific consensus. But that’s a misleading statement in an important way. The actual figure refers to “97 percent of climate scientists actively publishing in scientific journals.” To understand the relevance of this 97 percent figure, we need to know: what are the determiners of “actively publishing?”

    Could the selection process for entry and success (“actively publishing”) in the climate profession create a bias that compromises the information we rely on to make our critical decisions about climate?

    Let’s ask the question, calmly and rationally, and see where it takes us.

    1. It is reasonable to consider that children raised in climate-conscious families are more likely to become interested in the environment than those raised by families who either don’t care or who deny. The climate-conscious children are more likely to undertake science fair projects and write papers about climate change. Climate work is rewarded in school, so it shouldn’t be any surprise if such children, more than others, later consider environmental science as a college major. If this occurs, which seems likely, this childhood process would be Distillation Step 1 in creating a future climate scientist. More speculatively, if sufficiently reinforced, some of these youths might even develop some neuronally hardwired (unchangeable) biases as the brain matures.

    2. As is true in all fields, college climatology professors encourage the most dedicated students in introductory environmental studies classes to pursue climate science as a major. Other students—such as those who are skeptical—may never again see the inside of a climate science classroom. The selection of academic major is Distillation Step 2.

    3. When students pursue their master’s degrees, the crop of future climate scientists is further distilled. Those who don’t align with their professors’ views are less successful getting into PhD programs. Then, success within a PhD program relies (in any field) on abiding by one’s dissertation committee’s wishes so as to get their PhD in as few years as possible and finally make some money. During this phase, those who best comply will be more likely to obtain their doctorate and get set up in post-doc positions working for experienced senior scientists. Distillation Step 3 has occurred, along with further psychological reinforcement to agree with those more senior. The climate liquor is getting more concentrated.

    4. To succeed in academia, the newly minted PhD must apply for grants, mostly from government agencies or his own university. He chooses hypotheses and writes his grant application with care, knowing he’ll need the approval of committees populated with scientists who are invested in promoting their previously published papers and who make their living from government-funded studies of climate change. If he fails to craft his project to appeal to the needs of the reviewers on the committee, he won’t get funded. Funding failure increases the likelihood that he will wash out of academia. This selection of research grants to write is Distillation Step 4.

    The process of nurturing and selection of the climate scientist starts in kindergarten and proceeds through high school and college, then to grant funding, manuscript preparation, and publication. His research is then only seen through the lens of the media’s selective presentation. The many reinforcing layers of bias create a distillate of pure concentrated climate orthodoxy, and this liquor is what we are offered to drink.

    5. Successfully obtaining funding allows the young academic to perform a research project that will buttress the beliefs of the grant committee that channeled funding to him. Research studies are these days (improperly) designed to accomplish the affirmation of the hypothesized outcome as opposed to examining the truth of a hypothesis. If his project (done well or done poorly) appears to prove his hypothesis, then he tries to publish a paper to join the ranks of the “actively publishing.” He will craft the conclusion and abstract to promote his bias (again, this is true in any field). By the way, we should not underestimate the pressured academic’s skill at justifying to himself the removal of any data from his dataset that adversely affect his ability to get a publishable p value of “less than 0.05” (an arbitrary cut off in statistics that is needed for publication).

    Note that if the project fails to prove his hypothesis, the young scientist probably will never write a manuscript about it, and therefore he won’t yet be “actively publishing.” Oh, and often there are multiple hypotheses in a project, and if only one of them is proven, it will be the only one written up and submitted for publication. The disproven hypotheses will not be written up and will never be seen by us. This is all part of Distillation Step 5.

    6. Even if a scientist goes to the effort to write a manuscript that fails to support climate change concerns (which would be called a “negative manuscript” as it negates the hypothesis), it will be harder to get it published. Such “negative manuscripts” are, in any field, commonly rejected by the editor before going to peer review.

    If a negative manuscript does get to peer review, the reviewers will be more critical because the manuscript will conflict with their prior publications. Then the scientist will have to go to the considerable effort of resubmitting the manuscript elsewhere or have to respond to the reviewers’ critiques by getting more grant money and doing more studies, which will prove difficult. And it just isn’t worth it because publishing such a paper could only hurt his career. So the young academic understandably sticks the rejected manuscript and its data in a desk drawer, never to be seen again. This is Distillation Step #6.

    Selective manuscript writing, editorial bias, peer-review bias, and selective re-submission are four important biases in any field. This could be a reason—completely unrelated to scientific facts—as to why climate literature slants the way it does.

    After these multiple distillation steps, almost all impurities have been distilled away. Perhaps only 3 percent remains. It should be no more surprising that 97 percent of actively publishing climate scientists agree with the climate change consensus than that 97 percent of actively preaching seminary graduates believe in their religion.

    7. Those who make it onto the IPCC (Intergovernmental Panel on Climate Change), are the most highly distilled, fully vetted climate scientists of all. Pure 200 proof. For this reason and others, consensus at the level of the IPCC is even less useful than “expert opinion.”

    In response to climatologists’ complaints that the IPCC is biased against nuclear power, Jonathan Lynn, an IPCC spokesman, rejected the accusation, telling Axios: “We completely reject the idea we are biased about nuclear power or anything else.”

    I would call Mr. Lynn’s statement psychological denial. Of course the IPCC is biased. Everyone who cares, one way or the other, is biased. To say otherwise is poppycock.

    8. Now, if it bleeds it leads. The lay world only hears the most dramatic climate stories. What self-disrespecting mainstream click-baiting journalist will bother to read anything beyond a research abstract or would waste their editor’s time with anything positive (or even innocuous) regarding climate change? Answer: none. Furthermore, journalists now manage to stick a scary line about climate change in any article they can. Bees, birds, ticks, human migration… it’s all climate change. This continual exposure to unsubstantiated statements from journalists will bamboozle many readers.

    What we in the lay world get to read and hear is a highly distilled climate change liquor and the most catastrophic fears of what climate change may cause. The climate-concerned lay reader is unlikely to be presented with, or click on, a climate story that opposes his worldview. Those with defensive personalities will reflexively lash out with vitriol at an author of such an article, as if the author were an infidel, often without reading past the title.

    We need to get our heads around the climate in an intellectually comprehensive way. We need science to do that. Unfortunately, the politicized climate field has many reinforcing biases entrenched within it. This must lead to the dissemination of biased or incomplete facts and biased conclusions.

    Yet it is important we don’t get this wrong because people suffer and die when science becomes unquestioned dogma.

    We need private watchdogs who go to the effort to examine the research that the climatologists produce, looking for flaws, biases, misrepresentations, malincentives, and even manipulations. Instead of demonizing such skeptics, we need to encourage and respect such people who work hard to identify where biases have interfered with the pursuit of truth.

    I recognize the importance of a healthy climate. I am not ignoring facts, and I respect the scientific method. I’m not brainwashed by oil companies nor in psychological denial. To the contrary, any skepticism I have arises because I do not deny the weaknesses of the academic process that create a scientist and the research he produces. Reinforcing layers of bias can occur in any field, but politicization exaggerates it.

    Let’s remember what saved the whales. It wasn’t Greenpeace. It was, rather, the successful distillation of petroleum that replaced the demand for the renewable fuel known as whale oil. That distillation made petroleum purer and more flammable. The distillation of climate science makes it purer, too—and more incendiary.

    Policymakers, teachers, journalists, environmentalists…all of us…really know nothing about climate change other than what trickles down from the climate scientists’ desks. Are the many reinforcing layered biases of the climate field sufficient to have relevant effects on the research results that are presented to us? Are the climate scientists getting some of it wrong, or maybe exaggerating it?

    It has happened before—with DDT—with horrific consequences.

    And the climate change field is even more politicized.

  • Groupthink on Climate Change Ignores Inconvenient Facts

    Since we’ve now been living with the global warming story for 30 years, it might seem hard to believe that science could now come up with anything that would enable us to see that story in a wholly new light.

    But that is what I am suggesting in a new paper, just published in the UK by the Global Warming Policy Foundation, thanks to a book called Groupthink, written more than 40 years ago by a professor of psychology at Yale, Irving Janis.

    What Janis did was to define scientifically just how what he called groupthink operates, according to three basic rules. And what my paper tries to show is the astonishing degree to which they explain so much that many have long found puzzling about the global warming story.

    What Is Groupthink?

    Janis’s first rule is that a group of people come to share a particular way of looking at the world which may seem hugely important to them but which turns out not to have been based on looking properly at all the evidence. It is therefore just a shared, untested belief.

    Rule two is that, because they have shut their minds to any evidence which might contradict their belief, they like to insist that it is supported by a “consensus.” The one thing those caught up in groupthink cannot tolerate is that anyone should question it.

    This leads on to the third rule, which is that they cannot properly debate the matter with those who disagree with their belief. Anyone holding a contrary view must simply be ignored, ridiculed, and dismissed as not worth listening to.

    What my paper does is look again at the entire global warming story in the light of Janis’s rules, and to show how consistently they explain so much of the way it has unfolded all the way through.

    A Brief History of Climate Change

    The alarm over man-made climate change first exploded on the world in 1988 by a tiny group of scientists who had become convinced that, because both CO2 levels and global temperatures were rising, one must be the cause of the other. Unless something very drastic was done, they urged, the planet was heading for catastrophe.

    In November that year, two of these fervent believers in what they called “human-induced climate change” were authorized to set up the UN’s Intergovernmental Panel on Climate Change, the IPCC. This would report to the world’s politicians on the basis of computer models programmed, according to their theory, to predict just how fast the world was likely to heat up over the next 100 years.

    With startling speed, their theory was soon proclaimed as being supported by a scientific “consensus,” backed by governments, all the main scientific journals and institutions, environmental pressure groups, and the media.

    Questioning the “Consensus”

    In fact, right from the start, many scientists, like the eminent physicist Richard Lindzen of MIT, were highly skeptical, both of the theory itself and of those computer models. These, as Lindzen wrote, were so narrowly focused on CO2 that they were far too simplistic to allow for all the other natural factors which shape the earth’s climate.

    But such dissenters were ignored. And for nearly 20 years the “consensus” rolled on, ever more extreme in its apocalyptic claims, with each new IPCC report scarier than the last. By 2006, Al Gore’s An Inconvenient Truth was outdoing them all.

    Anyone daring to question the “consensus” was now being vilified as just an “anti-science denier,” no better than those crazies who deny the reality of the Nazi Holocaust.

    Just then, however, the story was beginning to change. It was noted that, since the abnormally hot year of 1998, caused by a record El Nino, global temperatures had not risen at all. Those computer models had not predicted this.

    Even more significant, thanks to the internet, expert science blogs were now appearing, able to show that not a single one of the claims from the “consensus” — vanishing Arctic ice, disappearing polar bears, unprecedented hurricanes, floods, droughts, etc. — was supported by the factual evidence.

    Calling the Bluff

    By 2009, the “consensus” was facing considerable embarrassment with the highly damaging Climategate emails between the little group of scientists at the heart of the IPCC followed by the collapse in disarray of the great Copenhagen climate conference.

    Then there was the spate of scandals surrounding the IPCC itself when it was revealed some of the scariest predictions of its latest report had not been based on proper science at all, but only on more hysterical claims by climate activists.

    Finally, in Paris in 2015, came what I describe as the crux of the whole story. This was yet another great global conference to decide what the world must do to avert catastrophe.

    Every nation had been asked in advance to submit its energy plans for the years up to 2030. The West, led by President Obama and the EU, dutifully pledged that it would be cutting its “carbon emissions” by up to 40 percent.

    But from the rest of the world, a totally different story emerged. China, by now the world’s largest CO2 emitter, was planning to build so many new coal-fired power stations that by 2030 its emissions would have doubled. India, the third largest emitter, was planning to triple them. Altogether global emissions by 2030 were set to rise by a staggering 46 percent.

    The rest of the world was just giving two fingers to the “consensus” and planning to carry on regardless. But not one Western leader mentioned this until 2017 when President Trump gave it as his reason for pulling the US out of that meaningless “Paris Accord.”

    In effect, Trump was thus finally calling the bluff of the groupthink which for 30 years had driven the whole global warming scare. If other Western countries wanted to commit economic suicide, that was their affair. But the rest of the world was no longer taken in by it, and the US was now with them.

  • How the Debate on Climate Change Is Cooling Down

    In a previous column, I noted that the typical audience reaction to my talks about the improving state of the world is not joy and thankfulness for the progress that humanity is making in tackling age-old problems such as infant mortality, malnutrition, and illiteracy. Rather, it is the concern about the exhaustion of natural resources and the supposedly irreparable harm that humanity is causing to the environment.

    Apocalyptic warnings about the end of the world as we know it are as old as humanity itself, but recent news should give the doomsayers some food for thought and lower the temperature, so to speak, in the debate about global warming and its future effects on the planet.

    The Models Were Wrong

    In a new study that was published in the journal Nature Geoscience, leading climate scientists have adjusted their previous predictions about global warming and stated that the worst impacts of climate change are still avoidable. Professor Michael Grubb, an international energy and climate change scientist at University College London, said that previous scientific estimates were incorrect because they were based on computer models that were running “on the hot side.”

    According to the new estimates, the world is more likely than previously thought to achieve the main goal of the 2015 Paris agreement and limit global warming to only 1.5°C higher than was the case in the pre-industrial era. Only two years ago, many scientists dismissed the 1.5°C goal as too optimistic and Professor Grubb went as far to say that “all the evidence from the past 15 years leads me to conclude that actually delivering 1.5°C” is unattainable.

    While it is true that the average global temperature is 0.9°C higher than in the pre-industrial era, the scientists now admit that there was a slowdown in warming in the 15 years prior to 2014 – a slowdown that the models did not predict or account for. Professor Myles Allen, another one of the study’s authors, said “We haven’t seen that rapid acceleration in warming after 2000 that we see in the models. We haven’t seen that in the observations.”

    What has changed in the model forecasts since the Paris summit in 2015? The data showing that the climate models are running “on the hot side” has been available for years. In 2015, my colleagues Patrick Michaels and Chip Knappenberger noted that climate models have been overestimating the rate of warming for decades. In 2016, John Christy from the University of Alabama in Huntsville testified before the US Congress that the climate models were inaccurate. For their trouble, all three have been labeled “climate change deniers.”

    The Nature Geoscience study suggests that humanity has more time to transition away from fossil fuels. Should it? That’s debatable, argues William Nordhaus, a professor of economics at Yale University, and his coauthor Andrew Moffatt, in a recently released paper for the National Bureau of Economic Research. The paper combines econometric and climate models to estimate the future impact of global warming on worldwide income.

    The Laws of Economics Still Apply

    By studying 36 estimates of the costs of global warming, the pair predicts that 3°C warming will reduce global income by 2.04 percent and 6°C warming will reduce global income by 8.16 percent by 2100. Nordhaus and Moffatt’s estimates parallel the broad consensus. For example, the IPCC in their Fourth Report estimated that global “mean losses could be 1 to 5 percent of GDP for 4°C of warming”.

    As Ronald Bailey of Reason magazine calculates, current global average income per capita is about $10,000. If the world grows at 3 percent per year over the next 80 years or so, global average income per capita will rise to $97,000. According to Nordhaus and Moffatt’s estimations, therefore, an increase in global temperature by 3°C would reduce global average income per capita by $2,000 to $95,000. A 6°C increase in global temperature would reduce global average income per capita by $8,000 to $89,000.

    “We have a predicament,” Bailey concludes. “How much are we willing to spend in order to make those living in 2100, who will likely be at least nine times richer than us today, $2,000 better off?”

    That is not a purely academic question. Thanks to the concerns over global warming, governments throughout the world have been busy imposing serious additional costs on economic development and reducing real living standards of ordinary people so as to facilitate the fastest possible transition away from fossil fuels. The above studies add to the complexity surrounding the subject of global warming and human response to it. They also strengthen the case of those who argue that any such transition should be driven by technological change, not government mandates.
