Attempts to settle a dispute by pointing to the other side’s motives are the stock in-trade of the political campaigner. In framing the argument on global warming in terms of scientific truth versus the false consciousness promoted by special interests, proponents of the idea of global warming inadvertently proclaim their adherence to a pseudo-science.
The argument that the public became confused about the science because of the activities of malign special interests (i.e., fossil fuel companies) is so ubiquitous as to be an intrinsic component in the morphology of global warming. It has been articulated by leading scientists (Michael Mann has written an entire book blaming the shortcomings of the Hockey Stick on special interests), politicians (Gordon Brown and Kevin Rudd, as well as Al Gore), and environmental NGOs. In 2012, William Nordhaus compared the ‘distortion’ of climate science to the activities of tobacco companies. ‘Scientists, citizens, and our leaders will need to be extremely vigilant to prevent pollution of the scientific process by the merchants of doubt,’ Nordhaus wrote, criticising global warming sceptics.[39]
It is also unhistorical. Despite the opposition of tobacco farmers and cigarette manufacturers, governments ran extensive anti-smoking campaigns and adopted other preventive measures, including vertiginously high taxes on tobacco. ‘By the close of the twentieth century, anti-tobacco advocates, public health officials, physicians’ groups, and international organisations, separately and in concert, had succeeded in putting tobacco control on the policy agenda of every industrialised democracy,’ Feldman and Bayer wrote.[40] Thanks to them, cigarette smoking has fallen in the Western world. As predicted by Doll, after a lag, lung cancer rates fell too.
Even the most ingenious maker of conspiracy theories would be hard pressed to forge a chain of causality linking the activities of Western fossil fuel companies to the refusal of India and China to accede to the West’s demands for a global cap on greenhouse gas emissions, especially as the Third World’s resistance to the claims of Western environmentalism had been adopted in the early 1970s – a decade and a half before the arrival of global warming in world politics in 1988.
So we come to the final paradox of global warming. The science is weak, but the idea is strong. The science is inherently weak because it is not capable of being falsified in the here and now. Voluminous evidence is itself testament to its weakness, for the same reasons Popper noted with respect to the trio of pseudo-sciences prevalent in Vienna in the 1920s.
Predictions that global warming will be harmful or dangerous are future statements which cannot be verified. By default, computer models have been used to guide governments, but they too depend on unverified assumptions about the cooling effect of aerosols.* But these models have failed to capture the amplitude of natural variability or to predict the absence of a clear trend in average global temperatures during the twenty-first century in what could be called Trenberth’s Travesty.*
Bias in the IPCC is endemic, from language of the expected signal of global warming emerging in the future, the cover-up of flaws in the Hockey Stick, its politicisation through government selection of lead authors and their control over what the IPCC says, to its infiltration by NGOs. ‘Despite the numbers of persons involved, and the lengthy formal review procedures, the preparation of the IPCC Assessment Reports is far from being a model of rigour, inclusiveness and impartiality,’ David Henderson wrote in a critique of the IPCC.[41]
After the Fourth Assessment Report was found to be full of errors, Working Group II co-chair Martin Parry wrote to colleagues characterising it as a ‘clamour without substance’ fed by critics and sceptics, at the same time defending the inclusion of NGO literature in IPCC output.[42] Bob Watson, the IPCC’s second chairman, thought otherwise. ‘The mistakes all appear to have gone in the direction of making it seem like climate change is more serious by overstating the impact. That is worrying,’ Watson said. ‘The IPCC needs to look at this trend in the errors and ask why it happened.’[43]
Yet global warming’s success in colonising the Western mind and in changing government policies has no precedent. It dominated the international agenda from the 1992 Rio Earth Summit until the 2008 banking crisis and the West’s defeat at Copenhagen a year later. The prospect of planetary salvation inflated the science so it became too big to fail, justifying the anti-scientific practice of withholding data and methods from potential critics and de-legitimising critical argument.* ‘What is called objectivity consists solely in the critical approach,’ Popper wrote.[44]
The credibility of global warming rested on the prestige of science – the branch of knowledge that had advanced further and faster than any other in human history. Underneath though, the nature of science was changing. It is hard to see a scientist such as Percy W. Bridgman in the middle of the twentieth century accepting with equanimity unverifiable future statements as science. Without the possibility of verification, Bridgman wrote, truth becomes meaningless.[45] Apply his criterion to the output of the IPCC, and there wouldn’t be much science left to furnish the basis of an immensely costly call to action.
This change was accompanied by a highly expansive view of the social role of scientists as uniquely capable of identifying and devising solutions to the problems threatening the survival of humanity and the planet. To this, scientists brought their cultural aversion to learning from the past. For them, history is not so much a closed book as irrelevant to the problems of the future. So they didn’t ask why previous predictions of imminent catastrophes, from Malthus and Jevons in the nineteenth century to the limits to growth debates of the early 1970s, were all wrong.
True to form, in 2012 the Royal Society produced the latest in the series of doomsday predictions. Unsurprisingly People and the Planet argued there were too many of the former for the latter.
Over the next thirty to forty years the confluence of the challenges described in this report provides the opportunity to move towards a sustainable economy and a better world for the majority of humanity, or alternatively the risk of social, economic and environmental failures and catastrophes on a scale never imagined.[46]
The last claim was untrue. Such catastrophes had been imagined. Exactly forty years earlier, Julian Huxley, winner of the Royal Society’s Darwin Medal, together with four other Fellows of the Royal Society and twenty-nine eminent scientists and experts, predicted the collapse of industrial civilisation in famine, epidemic and war within the lifetimes of people then living. ‘On a planet with finite resources there are limits to growth,’ the Royal Society stated, repeating the message of the Club of Rome’s The Limits to Growth, also from 1972, and making the same error.[47]
When it comes to learning from their mistakes, collectively scientists vie with the Bourbons.
In believing scientists and politicians can solve the problems of a far distant future, the tangible needs of the present are neglected. We cannot know what the future holds. It is like walking into a dense fog armed with a flashlight and one’s wits, picking out objects which we only know for sure what they are when nearly upon them.
No one knows what the Earth’s climate will be at the end of the century. Based on history, it is possible to hazard a prediction of a different kind. Before the end of the century, the Western mind will conceive another environmental crisis necessitating the ending of the modern industrial economy, the only form of economic arrangements that has lifted mankind to undreamt of prosperity.
The big question is whether the Western mind will be sovereign at the century’s end and the West remain the core of the world economy or relegated to its periphery – something only the passing of the present century can answer.
* An example is provided by Naomi Oreskes, historian of science and co-author of Merchants of Doubt: How a Handful of Scientists Obscured the Truth on Issues from Tobacco Smoke to Global Warming (2010). In an interview on Australian radio, Oreskes said: ‘Well, of course, no one can ever say, a hu
ndred per cent, that any particular individual piece of science is correct, but that’s what the scientific process is all about. And over the past four hundred years, scientists have developed mechanisms for evaluating scientific work, and the most important mechanism is peer review.’ The World Today, 19th October 2010.
* ‘Buried’ is the right word to use about the IPCC’s handling of subjectivity. It does not appear in any of the summaries for policymakers in the IPCC’s 2007 Fourth Assessment Report. Neither does it appear in the crucial Chapter Nine on understanding and attributing climate change, but is buried in the chapter’s supplementary material.
* In its 2007 Fourth Assessment Report, the IPCC acknowledged that observational uncertainty, uncertainty about external influences on the climate (‘forcing uncertainty’) and internal climate variability affect the width of probable outcomes (‘the prior distribution’). The prior distribution used in the calculations, the IPCC authors wrote, ‘indicates that little is known, a priori, about the parameters of interest except that they are bounded below and above. Even so, the choice of prior bounds can be subjective’. Hegerl, G.C., F.W. Zwiers, P. Braconnot, N.P. Gillett, Y. Luo, J.A. Marengo Orsini, N. Nicholls, J.E. Penner and P.A.

* Notoriously the US tobacco industry ran an advertising campaign in the 1950s claiming that its customers’ health was the industry’s overriding concern. The response of the UK industry was different. After the industry’s chief statistician was sacked for saying he would resign unless the tobacco industry accepted that smoking caused lung cancer, he was reinstated six weeks later and the industry agreed not to say anything to imply that smoking did not cause lung cancer. Conrad Keating, Smoking Kills: The Revolutionary Life of Richard Doll (2009), pp. 183–6.
* According to Richard Lindzen, ‘The models focus on aerosols and solar variability, and generally assume that natural internal variability is accurately included and accounted for. That models each use different assumptions for aerosols and solar variability makes clear that these are simply adjustable parameters.’ Richard S. Lindzen, ‘Response to the critique of my lecture in the House of Commons on 22nd February 2012’, 12th April 2012 http://thegwpf.org/the-climate-record/5437-richard-lindzen-response-to-the-critique-of-my-house-of-commons-lecture.html
* For example, Brian Hoskins, J. Mitchell, T. Palmer, K. Shine & E. Wolff wrote that the termination of the most recent glaciation, with a small initial rise in temperatures followed by several thousand years in which temperatures and CO2 rose together, ‘is entirely consistent with the role of CO2 as an amplifier of an otherwise small external forcing’ (A critique of the scientific content of Richard Lindzen’s Seminar in London, 22nd February 2012). In response, Lindzen wrote: ‘The notion that the small changes in globally and annually averaged insolation are the crucial driver is implausible to say the least, but it stems from the current simplistic view of climate consisting in a single variable (globally averaged temperature anomaly) forced by some globally averaged radiative forcing – an idea that permeates the critics’ discussion.’ Richard S. Lindzen, ‘Response to the critique of my lecture in the House of Commons on 22nd February 2012’ 12th April 2012 http://thegwpf.org/the-climate-record/5437-richard-lindzen-response-to-the-critique-of-my-house-of-commons-lecture.html
* ‘There are considerable uncertainties in estimating the impact of aerosols on climate,’ according to Hoskins et al., who go on to say that ‘uncertain’ does not mean ‘unknown’ or that the cooling effect of aerosols is zero. Brian Hoskins, J. Mitchell, T. Palmer, K. Shine & E. Wolff, A critique of the scientific content of Richard Lindzen’s Seminar in London, 22nd February 2012 (undated).
* According to Lindzen, ‘The assumption that the models adequately represent natural internal variability is seriously mistaken.’ Richard S. Lindzen, ‘Response to the critique of my lecture in the House of Commons on 22nd February 2012’.
* Hill and Doll’s findings on tobacco and lung cancer were fiercely attacked by R.A. Fisher, the leading geneticist and statistician of the period (Fisher formulated the null hypothesis test), who demanded to see the underlying data. Hill and Doll passed two data sets to Fisher.
