"Scientific heresy"

To whet your appetite:
The [IPCC's] glacier claim was not peer reviewed; nor was the alteration to the sensitivity function Lewis spotted. The journalist Donna Laframboise got volunteers all over the world to help her count the times the IPCC used non-peer reviewed literature. Her conclusion is that*: “Of the 18,531 references in the 2007 Climate Bible we found 5,587 - a full 30% - to be non peer-reviewed.”

Yet even to say things like this is to commit heresy. To stand up and say, within a university or within the BBC, that you do not think global warming is dangerous gets you the sort of reaction that standing up in the Vatican and saying you don’t think God is good would get. Believe me, I have tried it.

Does it matter? Suppose I am right that much of what passes for mainstream climate science is now infested with pseudoscience, buttressed by a bad case of confirmation bias, reliant on wishful thinking, given a free pass by biased reporting and dogmatically intolerant of dissent. So what?

After all there’s pseudoscience and confirmation bias among the climate heretics too.

Well here’s why it matters. The alarmists have been handed power over our lives; the heretics have not. Remember Britain’s unilateral climate act is officially expected to cost the hard-pressed UK economy £18.3 billion a year for the next 39 years and achieve an unmeasurably small change in carbon dioxide levels.

At least* sceptics do not cover the hills of Scotland with useless, expensive, duke-subsidising wind turbines whose manufacture causes pollution in Inner Mongolia and which kill rare raptors such as this griffon vulture.

At least crop circle believers cannot almost double your electricity bills and increase fuel poverty while driving jobs to Asia, to support their fetish.

At least creationists have not persuaded the BBC that balanced reporting is no longer necessary.

At least homeopaths have not made expensive condensing boilers, which shut down in cold weather, compulsory, as John Prescott did in 2005.

At least astrologers have not driven millions of people into real hunger, perhaps killing 192,000 last year according to one conservative estimate, by diverting 5% of the world’s grain crop into motor fuel*.

That’s why it matters. We’ve been asked to take some very painful cures. So we need to be sure the patient has a brain tumour rather than a nosebleed.

Handing the reins of power to pseudoscience has an unhappy history. Remember eugenics. Around 1910 the vast majority of scientists and other intellectuals agreed that nationalizing reproductive decisions so as to stop poor, disabled and stupid people from having babies was not just a practical but a moral imperative of great urgency.

“There is now no reasonable excuse for refusing to face the fact,” said George Bernard Shaw*, “that nothing but a eugenics religion can save our civilization from the fate that has overtaken all previous civilizations.’’ By the skin of its teeth, mainly because of a brave Liberal MP called Josiah Wedgwood, Britain never handed legal power to the eugenics movement. Germany did.

Or remember Trofim Lysenko*, a pseudoscientific crank with a strange idea that crops could be trained to do what you wanted and that Mendelian genetics was bunk. His ideas became the official scientific religion of the Soviet Union and killed millions; his critics, such as the geneticist Nikolai Vavilov, ended up dead in prison.

Am I going too far in making these comparisons? I don’t think so. James Hansen of NASA says oil firm executives should be tried for crimes against humanity. (Remember this is the man who is in charge of one of the supposedly impartial data sets about global temperatures.) John Beddington, Britain's chief scientific adviser, said this year that just as we are "grossly intolerant of racism", so we should also be "grossly intolerant of pseudoscience", in which he included all forms of climate-change scepticism.

Do send it to your friends and family.
