The Climate Wars are Damaging Science

Matt Ridley has produced the shortest whole, killer summary of the sordid state of climate science, science journalism, and science associations for Quadrant magazine. This is the ideal single-chapter-length-work to bring in anyone who missed the last twenty years of clima-farce, scandal, hubris and hypocrisy.

Matt is not just summing up the way his career as a science writer has transformed, but also writing the best review of the IPA book “Climate Change: The Facts” that I have yet seen. He talks about the way science writers used to ignore the papers that didn’t impress them, and leave it up to the scientists to take them apart, but now the supposedly most esteemed scientists stay silent while abject failures not only get published in the scientific world, but get absurdly lauded in the media, and tweeted by “the President”. Formerly great scientific institutions have turned themselves inside out:

“The Royal Society once used to promise “never to give their opinion, as a body, upon any subject”. Its very motto is “nullius in verba”: take nobody’s word for it. Now it puts out catechisms of what you must believe in. “

Matt’s career, like mine, started with faith that science and the human industries of it, were self-correcting.  For much of my life I have been a science writer”, he explains,  but now “…thanks largely to climate science, I have changed my mind. It turns out bad ideas can persist in science for decades, and surrounded by myrmidons of furious defenders they can turn into intolerant dogmas.” He feels betrayed by an industry he once championed. I too used to communicate the awe and value of research, but now end up mostly only awed at the mountain of money wasted on self-satirical works like Lewandowsky, and Cook et al. I mock my former alma maters, UWA and ANU. My role in science communication is to point out the grand failure of my profession, who are trained to sell science to the public, but should be serving the public by asking the hard questions instead. Science Communicators should be the guardians of the scientific method,  but most science writers don’t seem to know what it is. They should be the backstop when the institutions of science fail, not the cheerleaders for wasted public funds.

If you enjoy Matt’s article, you’ll enjoy the whole book — available through the IPA in Australia and now at Amazon in paperback: Climate Change: The Facts, and kindle.

I wrote about monopolistic funding and the rise of the volunteer auditors back in 2009, and Matt is one of the few to carry and develop this theme, documenting the importance of political support and the rise of the science bloggers to fill the vacuum.   Where, he asks, is the outrage from mainstream scientists? Where indeed?

The democratisation of science

Any one of these scandals in, say, medicine might result in suspensions, inquiries or retractions. Yet the climate scientific establishment repeatedly reacts as if nothing is wrong. It calls out any errors on the lukewarming end, but ignores those on the exaggeration end. That complacency has shocked me, and done more than anything else to weaken my long-standing support for science as an institution. I repeat that I am not a full sceptic of climate change, let alone a “denier”. I think carbon-dioxide-induced warming during this century is likely, though I think it is unlikely to prove rapid and dangerous. So I don’t agree with those who say the warming is all natural, or all driven by the sun, or only an artefact of bad measurement, but nor do I think anything excuses bad scientific practice in support of the carbon dioxide theory, and every time one of these scandals erupts and the scientific establishment asks us to ignore it, I wonder if the extreme sceptics are not on to something. I feel genuinely betrayed by the profession that I have spent so much of my career championing.

There is, however, one good thing that has happened to science as a result of the climate debate: the democratisation of science by sceptic bloggers. It is no accident that sceptic sites keep winning the “Bloggies” awards. There is nothing quite like them for massive traffic, rich debate and genuinely open peer review.

Well, internet trolls are roaming the woods in every subject, so what am I complaining about? The difference is that in the climate debate they have the tacit or explicit support of the scientific establishment. Venerable bodies like the Royal Society almost never criticise journalists for being excessively alarmist, only for being too lukewarm, and increasingly behave like pseudoscientists, explaining away inconvenient facts.

Matt writes with speed and wit, adroitly packing whole scandals into a mere paragraph.

Jim Hansen, recently retired as head of the Goddard Institute of Space Studies at NASA, won over a million dollars in lucrative green prizes, regularly joined protests against coal plants and got himself arrested while at the same time he was in charge of adjusting and homogenising one of the supposedly objective data sets on global surface temp. How would he be likely to react if told of evidence that climate change is not such a big problem?

He writes about the bizarre overt Psychology of Taboo that is used to crush the mildest debate and to polarize those who take a sensible, but invisible, middle road:

But the commentators ignore all these caveats and babble on about warming of “up to” four degrees (or even more), then castigate as a “denier” anybody who says, as I do, the lower end of the scale looks much more likely given the actual data. This is a deliberate tactic. Following what the psychologist Philip Tetlock called the “psychology of taboo”, there has been a systematic and thorough campaign to rule out the middle ground as heretical: not just wrong, but mistaken, immoral and beyond the pale. That’s what the word denier with its deliberate connotations of Holocaust denial is intended to do. For reasons I do not fully understand, journalists have been shamefully happy to go along with this fundamentally religious project.

So where’s the outrage from scientists at this presidential distortion? It’s worse than that, actually. The 97 per cent figure is derived from two pieces of pseudoscience that would have embarrassed a homeopath. The first was a poll that found that 97 per cent of just seventy-nine scientists thought climate change was man-made—not that it was dangerous. A more recent poll of 1854 members of the American Meteorological Society found the true number is 52 per cent.

The second source of the 97 per cent number was a survey of scientific papers, which has now been comprehensively demolished by Professor Richard Tol of Sussex University, who is probably the world’s leading climate economist. As the Australian blogger Joanne Nova summarised Tol’s findings, John Cook of the University of Queensland and his team used an unrepresentative sample, left out much useful data, used biased observers who disagreed with the authors of the papers they were classifying nearly two-thirds of the time, and collected and analysed the data in such a way as to allow the authors to adjust their preliminary conclusions as they went along, a scientific no-no if ever there was one. The data could not be replicated, and Cook himself threatened legal action to hide them. Yet neither the journal nor the university where Cook works has retracted the paper, and the scientific establishment refuses to stop citing it, let alone blow the whistle on it. Its conclusion is too useful.

This should be a huge scandal, not fodder for a tweet by the leader of the free world. Joanne Nova, incidentally, is an example of a new breed of science critic that the climate debate has spawned. With little backing, and facing ostracism for her heresy, this talented science journalist had abandoned any chance of a normal, lucrative career and systematically set out to expose the way the huge financial gravy train that is climate science has distorted the methods of science. In her chapter in The Facts, Nova points out that the entire trillion-dollar industry of climate change policy rests on a single hypothetical assumption, first advanced in 1896, for which to this day there is no evidence.

The assumption is that modest warming from carbon dioxide must be trebly amplified by extra water vapour—that as the air warms there will be an increase in absolute humidity providing “a positive feedback”. That assumption led to specific predictions that could be tested. And the tests come back negative again and again. The large positive feedback that can turn a mild warming into a dangerous one just is not there. There is no tropical troposphere hot-spot. Ice cores unambiguously show that temperature can fall while carbon dioxide stays high. Estimates of climate sensitivity, which should be high if positive feedbacks are strong, are instead getting lower and lower. Above all, the temperature has failed to rise as predicted by the models.

Matt Ridley was one of the writers, like Mark Steyn, I used to admire from a distance when I was an underling in the science communication world. It is one of the few but priceless rewards of taking the hard road — to know them both.

Mark Steyn has the full list of Amazon subsidiary pages to buy The Book.

This is just one sixth of the full excellent essay at Quadrant magazine.
