Support More Febrile and Shrill

Will Science Regain Respect?

The Global Warming spin machine has been aided and abetted by disreputable and unprofessional behaviour on the part of many scientists. They have tarred all scientists with a dirty, unsavoury brush. The entire episode has demonstrated powerfully that relative objectivity and research integrity can no longer be expected in scientific disciplines.

Two important pieces have been published recently which deserve attention. The first was a piece in the Sydney Morning Herald by Michael Duffy publicly exposing the charlatan-like behaviour of the Chairman of the UN IPCC when recently in Sydney.

Truly inconvenient truths about climate change being ignored

Michael Duffy
November 8, 2008

Last month I witnessed something shocking. Rajendra Pachauri, chairman of the Intergovernmental Panel on Climate Change, was giving a talk at the University of NSW. The talk was accompanied by a slide presentation, and the most important graph showed average global temperatures. For the past decade it represented temperatures climbing sharply.

As this was shown on the screen, Pachauri told his large audience: "We're at a stage where warming is taking place at a much faster rate [than before]".

Now, this is completely wrong. For most of the past seven years, those temperatures have actually been on a plateau. For the past year, there's been a sharp cooling. These are facts, not opinion: the major sources of these figures, such as the Hadley Centre in Britain, agree on what has happened, and you can check for yourself by going to their websites. Sure, interpretations of the significance of this halt in global warming vary greatly, but the facts are clear.

So it's disturbing that Rajendra Pachauri's presentation was so erroneous, and would have misled everyone in the audience unaware of the real situation. This was particularly so because he was giving the talk on the occasion of receiving an honorary science degree from the university.

Later that night, on ABC TV's Lateline program, Pachauri claimed that those who disagree with his own views on global warming are "flat-earthers" who deny "the overwhelming weight of scientific evidence". But what evidence could be more important than the temperature record, which Pachauri himself had fudged only a few hours earlier?

In his talk, Pachauri said the number of global warming sceptics is shrinking, a curious claim he was unable to substantiate when questioned about it on Lateline. Still, there's no doubt a majority of climate scientists agree with the view of the IPCC.

Today I want to look at why this might be so: after all, such a state of affairs presents a challenge to sceptics such as me. If we're right, then an awful lot of scientists are wrong. How could this be?

This question was addressed in September in a paper by Professor Richard Lindzen, of the Program in Atmospheres, Oceans and Climate at Massachusetts Institute of Technology. Lindzen, probably the most qualified prominent global-warming sceptic, suggested that a number of changes in the way science is conducted have contributed to the rise of climate alarmism among American scientists.

Central to this is the importance of government funding to science. Much of that funding since World War II has occurred because scientists build up public fears (examples include fear of the USSR's superiority in weapons or space travel, of health problems, of environmental degradation) and offer themselves as the solution to those fears. The administrators who work with the scientists join in with enthusiasm: much of their own funding is attached to the scientific grants. Lindzen says this state of affairs favours science involving fear, and also science that involves expensive activities such as computer modelling. He notes we have seen "the de-emphasis of theory because of its difficulty and small scale, the encouragement of simulation instead (with its call for large capital investment in computation), and the encouragement of large programs unconstrained by specific goals.

"In brief, we have the new paradigm where simulation and [computer] programs have replaced theory and observation, where government largely determines the nature of scientific activity, and where the primary role of professional societies is the lobbying of the government for special advantage."

Lindzen believes another problem with climate science is that in America and Europe it is heavily colonised by environmental activists.

Here are just two examples that indicate the scale of the problem: the spokesman for the American Meteorological Society is a former staffer for Al Gore, and realclimate.org, probably the world's most authoritative alarmist web site, was started by a public relations firm serving environmental causes.

None of this is necessarily sinister, but the next time you hear a scientist or scientific organisation warning of climate doom, you might want to follow the money trail. Sceptics are not the only ones who have received funding from sources sympathetic to their viewpoint. (And yes, Lindzen did once receive some money from energy companies.)

Lindzen claims that scientific journals play an important role in promoting global warming alarmism, and gives a number of examples.

Someone else who's looked closely at scientific journals (although not specifically those dealing with climate science) is epidemiologist John Ioannidis of the Tufts University School of Medicine in Boston. He reached the surprising conclusion that most published research findings are proved false within five years of their publication. (Lest he be dismissed as some eccentric, I note that the Economist recently said Ioannidis has made his case "quite convincingly".)

Why might this be so? Later work by Ioannidis and colleagues suggests that these days journal editors are more likely to publish research that will make a splash than that which will not. They do this to sell more copies of their publications and of reprints of papers in it. Ioannidis believes these publication practices might be distorting science.

It's possible the forces described by Lindzen and Ioannidis have imbued climate science with a preference for results that involve (or seem to involve) disastrous change rather than stability. Rajenda Pachauri's recent Sydney lecture suggests that in this relatively new field, inconvenient truths to the contrary are not welcome.

"Objective scientific inquiry" is becoming more and more an oxymoron, to the point where one wonders whether it will ever recover.

The second piece is much longer, and we will not re-publish in full. However, it is definitely worth serious reflection. The article appears in Quadrant Magazine and its full text can be found here.

The article is written by Robert Carter, and is entitled "The Futile Quest for Climate Control."

We reproduce excerpts below:

Climate change knows three realities: science reality, which is what working scientists deal with every day; virtual reality, which is the wholly imaginary world inside computer climate models; and public reality, which is the socio-political system within which politicians, business people and the general citizenry work.

The science reality is that climate is a complex, dynamic, natural system that no one wholly comprehends, though many scientists understand different small parts. So far, science provides no unambiguous evidence that dangerous or even measurable human-caused global warming is occurring.

The virtual reality is that computer models predict future climate according to the assumptions that are programmed into them. . . .

The public reality in 2008 is that, driven by strong environmental lobby groups and evangelistic scientists and journalists, there is a widespread but erroneous belief in our society that dangerous global warming is occurring and that it has human causation. . . .

Science reality.

My reference files categorise climate change into more than 100 sub-discipline areas of relevant knowledge. Like most other climate scientists, I possess deep expertise in at most two or three of these sub-disciplines. As Christopher Essex and Ross McKitrick (in Taken by Storm) have observed:

“Global warming is a topic that sprawls in a thousand directions. There is no such thing as an ‘expert’ on global warming, because no one can master all the relevant subjects. On the subject of climate change everyone is an amateur on many if not most of the relevant topics.”

It is therefore a brave scientist who essays an expert public opinion on the global warming issue, that bravery being always but one step from foolhardiness. As for the many public dignitaries and celebrities whose global warming preachings fill our daily news bulletins, their enthusiasm for a perceived worthy cause greatly exceeds their clarity of thought about climate change science, regarding which they are palpably innocent of knowledge.

In these difficult circumstances of complex science and public ignorance, how is science reality to be judged? This question was first carefully thought through in the late 1980s by the senior bureaucrats and scientists who were involved in the creation of the United Nations Intergovernmental Panel on Climate Change (IPCC). . . The declared intention of the IPCC was to provide disinterested summaries of the state of climate science as judged from the published, refereed scientific literature. Henceforward, in the public and political eye, science reality was to be decided by the authority of the IPCC. Accordingly, in four successive Assessment Reports in 1990, 1995, 2001 and 2007, the IPCC has tried to imprint its belief in dangerous human-caused warming on politicians and the public alike, steamrolling relentlessly over the more balanced, non-alarmist views held by thousands of other qualified scientists. Inevitably, and despite the initial good intentions, what started in 1988 as a noble cause had by the time of the fourth Assessment Report (2007) degenerated into a politically-driven science and media circus.

As Essex and McKitrick have accurately written:

“We do not need to guess what is the world view of the IPCC leaders. They do not attempt to hide it. They are committed, heart and soul, to the Doctrine [of human-caused global warming]. They believe it and they are advocates on its behalf. They have assembled a body of evidence that they feel supports it and they travel the world promoting it.

“There would be nothing wrong with this if it were only one half of a larger exercise in adjudication. But governments around the world have made the staggering error of treating the IPCC as if it is the only side we should listen to in the adjudication process. What is worse, when on a regular basis other scientists and scholars stand up and publicly disagree with the IPCC, governments panic because they are afraid the issue will get complicated, and undermine the sense of certainty that justifies their policy choices. So they label alternative views ‘marginal’ and those who hold them ‘dissidents’. . . .

The hypothesis of the IPCC was, and remains, that human greenhouse gas emissions (especially of carbon dioxide) are causing dangerous global warming. The IPCC concentrates its analyses of climate change on only the last few hundred years, and has repeatedly failed to give proper weight to the geological context of the 150-year-long instrumental record. When viewed in historical context, and assessed against empirical data, the greenhouse hypothesis fails. There is no evidence that late-twentieth-century rates of temperature increase were unusually rapid or reached an unnaturally high peak; no human-caused greenhouse signal has been measured or identified despite the expenditure since 1990 of many billions of dollars searching for it; and global temperature, which peaked within the current natural cycle in 1998, has been declining since 2002 despite continuing increases in carbon dioxide emission.

Therefore, science reality in 2008 is that the IPCC’s hypothesis of dangerous, human-caused global warming has been repeatedly tested and failed. In contrast, the proper null hypothesis that the global climatic changes that we observe today are natural in origin has yet to be disproven. The only argument that remains to the IPCC—and it is solely a theoretical argument, not evidence of any kind—is that their unvalidated computer models project that carbon-dioxide-driven dangerous warming will occur in the future: just you wait and see! It is therefore to these models that we now turn.

Virtual reality.

The general circulation computer climate models (GCMs) used by the IPCC are deterministic, which is to say that they specify the climate system from the first principles of physics. For many parts of the climate system, such as the behaviour of turbulent fluids or the processes that occur within clouds, our incomplete knowledge of the physics requires the extensive use of parameterisation (that is, “educated guesses”) in the models, especially for the many climate processes that occur at a scale below the 100 to 200 square kilometre size of the typical modelling grid.

Not surprisingly, therefore, the GCMs used by the IPCC have not been able to make successful climate predictions, nor to match the observed pattern of global temperature change over the late twentieth century. Regarding the first point, none of the models was able to forecast the path of the global average temperature statistic as it elapsed between 1990 and 2006. Regarding the second, GCMs persistently predict that greenhouse warming trends should increase with altitude, especially in the tropics, with most warming at around ten kilometres altitude; in contrast, actual observations show the opposite, with either flat or decreasing warming trends with increasing height in the troposphere. . . .

It is clear from all of this that climate GCMs do not produce predictive outputs that are suitable for direct application in policy making; it is therefore inappropriate to use IPCC model projections for planning, or even precautionary, purposes, as if they were real forecasts of future climate. . . .

Public reality.

Opinion polls show that most of the rest of us have become severely alarmed about the threat of human-caused climate change. Therefore, public reality, as perceived by the Rudd government at least, is that the Australian electorate now expects the government to “do something” about global warming—that is, to introduce a carbon dioxide taxation system. This means that there exists a strong disjunction between climate alarm as perceived by the public and the science justification for that alarm. How come? . . . .

. . . (P)robably the strongest alarmist influence of all on the climate policy debate is the rather more subtle phenomenon of noble cause corruption.

In his book Science and Public Policy, Professor Aynsley Kellow explores the problem of noble cause corruption in public life in some depth. Such corruption arises from the belief of a vested interest, or powerful person or group, in the moral righteousness of their cause. For example, a police officer may apprehend a person committing a crime and, stuck with a lack of incriminating evidence, proceed to manufacture it. For many social mores, of which “stopping global warming” and “saving the Great Barrier Reef” are two iconic Australian examples, it has become a common practice for evidence to be manipulated in dishonest ways, under the justification of helping to achieve a worthy end. After all, who wouldn’t want to help to “save the Great Barrier Reef”? . . . .

Driven by their addiction to alarmism, and a false belief that the causes of climate change are understood, environmentalists worldwide urge the adoption of the precautionary principle to solve the “global warming problem”. The reality that you can’t take precautions against a future that is unknown (and may encompass either warming or cooling, or both) is ignored in favour of irrational feel-goodery, the aim being to move the world to a “post-carbon” economy by drastic curtailment of the carbon dioxide emissions that are alleged to be causing warming.

Environmental campaigners for the reduction of human greenhouse emissions remain blind to inconvenient facts such as: that no amount of precaution is going stop natural climate change; that there is a 100 per cent risk of damage from natural climate events, which happen every day; that we cannot measure, much less isolate, any presumed human climate signal globally; that extra atmospheric carbon dioxide causes mild warming at best, and overall is at least as likely to be beneficial as harmful; and that the causes of climate change are many, various and very incompletely understood. . . .

The Role of the Media in Fostering Climate Alarmism

It is a rare day now that any metropolitan newspaper fails to carry one or more alarmist stories on climate change, not least because media proprietors learned long ago that sensational or alarmist news sells best. As one of Australia’s most experienced science journalists, Julian Cribb, has remarked:

“The publication of ‘bad news’ is not a journalistic vice. It’s a clear instruction from the market. It’s what consumers, on average, demand … As a newspaper editor I knew, as most editors know, that if you print a lot of good news, people stop buying your paper. Conversely, if you publish the correct mix of doom, gloom and disaster, your circulation swells. I have done the experiment.”

Thus climate change hysteria in the media has a life of its own. Ask a web search engine to supply you with references to “global warming” and it will provide a daily haul of ten to twenty alarmist newspaper articles from throughout the world. Many of these stories have as their basis real scientific results from real scientists, but by the time the results been processed through public relations staff and compliant media commentators, the result is group-think, political correctness and frisbee-science of a high order. . . .

The British commentator Melanie Phillips summarised it well:

“The way global warming is being reported by the science press is a scandal. In selecting only those claims that support a prejudice and disregarding evidence that these claims are false, it is betraying the basic principles of scientific inquiry and has become instead an arm of ideological propaganda.”

Finally, for all the problems listed above, and much to the outrage of warming alarmists, it should be acknowledged that a handful of quality newspapers do provide a more balanced public discussion of global warming issues. Such papers include the Wall Street Journal, the London Telegraph stable, the Canadian National Post, the Melbourne Business Age and the Australian. These publications, and a few others, are playing a vital role in keeping the public informed of both sides of the climate change issue. Tellingly, however, no Australian television station comes even close to providing equivalently balanced commentary; and neither does that paragon of broadcasting virtue, the British Broadcasting Corporation. . . .


Conclusions

In 1990 the IPCC’s first Assessment Report concluded that no human influence on climate was discernible. Despite the huge expenditure of research effort and money since that time, the boundary arguments to the debate have scarcely moved. We now have copiously more data and more powerful computers, have spent upwards of $50 billion on climate research, and are the beneficiaries of twenty years of hard thinking by some of the world’s most accomplished scientists. Yet the protagonists in the debate remain in the same bunkers they occupied in the early 1990s, and a clear human-caused climate signal continues to elude us.

Two years ago, I wrote:

“It remains a matter of faith whether reductions in carbon dioxide emissions, should they occur, will have any measurable influence on climate. My conclusion is that—irrespective of McCarthyist bludgeoning, press bias, policy-advice corruption or propaganda frenzy—it is highly unlikely that the public is going to agree to a costly restructuring of the world economy simply on the basis of speculative computer models of climate in 100 years time. Attempting to ‘stop climate change’ is an extravagant and costly exercise of utter futility. Rational climate policies must be based on adaptation to climate change as it occurs, irrespective of its causation.” . . . .

The IPCC experiment has failed, in large part because of the priority that has been given to policy advocacy over the accurate reporting of empirical science. Attempting to prevent (“mitigate”, in the lingo) climate change is an expensive exercise in futility. Planning for inevitable future climate change, both natural and possibly human-caused, will best be undertaken in the same way as we plan for other natural disasters such as bushfires, earthquakes, volcanic eruptions, tsunami and cyclones. Policies are needed which identify when a dangerous climatic event is about to occur, or has occurred; which then initiate any available, cost-effective mitigation measures; and which, finally, provide appropriate assistance to those individuals or communities affected by the change through no fault of their own. . . .

Natural climate change being an important human hazard, research funding for climate change issues should be maintained at a healthy level. But the focus of the spending needs to be shifted from its present overemphasis on “greenhouse” alarmism and computer modelling research to a balance of: (i) documentation and analysis of modern weather patterns (earth observing systems), and patterns of past climate change (stratigraphic study); and (ii) deepening our understanding of all mechanisms of climate change, not just radiation theory. . . .
