I am an arts and (though I shudder to associate Law with such "disciplines" as Sociology) social sciences man. My interests are literature, theatre and history. I love technology, but all I know about serious science is Professor Karl Popper's* explanation of the scientific method as the postulation of hypotheses followed by the performance of rigorous experiments to falsify them, resulting in provisional "truths".
One of the first bloggers I followed was A.W. Montford, known to me until recently only as Bishop Hill. Of late he has found a new audience on the topic of climate change. I have just finished his book The Hockey Stick Illusion. I feared it would be hard going but I was wrong. Despite some necessary (and thank goodness elegant) explanations of abstruse complexities, it is a page-turner. I commend it to you.
In reading it, I have acquired a new hero - a rare event at my time of life. Steve McIntyre has something in common with one of my other heroes, John Harrison. Both were derided by the closed ranks of the scientific establishment, largely on the basis of a snobbish reaction against an unqualified** "outsider." Harrison's inventions made the modern world possible. McIntyre's work (done for intellectual curiosity and at his own expense) may yet save it.
A prize-winning mathematician as a young man in Canada, McIntyre's family circumstances dictated a remunerative practical life as a mining engineer, rather than in academia. In retirement, he became interested in climate science, his gut instincts telling him that there was something wrong with a leaflet sent to every home in Canada in 2002 to promote the Kyoto Protocol. His reading led him to the work of Professor Michael E. Mann. Mann's paper, published in Nature on 23rd April 1998, strongly influenced the IPCC's and the world's politicians' view that anthropogenic global warming (AGW, or colloquially "climate change") was a potentially apocalyptic threat. A graph from that paper, showing the Earth's temperature as steady for centuries, with a sudden up-tick post-industrialisation, became the most influential image in selling AGW theory to the world. It (in its various forms over the years) is known as "the Hockey Stick" and its scientific supporters, clustered around Mann, are known as "the Hockey Team."
Many of you will have seen the graph behind Al Gore as he presented An Inconvenient Truth. You will certainly have seen it somewhere. It's burned onto our collective consciousness and it's in our childrens' school books. It's also based on flawed science and is pretty much discredited. Yet it continues to influence policy across the world, to the possible detriment of human civilisation.
Professor Mann is a poor scientist and a weak man, but not a bad person. He's sincere, as are the vast majority of proponents of the AGW hypothesis. He foresees catastrophic peril to humanity and is frustrated by those who doubt it and therefore impede (as he sees it) the necessary solutions. I am sure he was sincere in writing the original paper and in all his subsequent (sometimes dishonest) defences of it. I even believe, sadly, that he has been sincere in trashing his "opponents" and seeking to prevent their work from being published in the journals.
I imagine he feels such means are justified by a noble end. Sadly, that is how almost all corruption begins. One way to know you are going wrong in life is to catch yourself spinning data to serve your heartfelt objectives. His enemies point out that the paper and particularly the Hockey Stick propelled him from being a 33 year old unknown who had just completed his doctorate, to being one of the most influential scientists on Earth. He has certainly benefitted from it, but few men are evil enough to condemn billions to poverty for personal gain or glory. There are some such, no doubt, but I don't believe he is among them. It seems sadly clear however that for whatever (probably noble) reason, he has betrayed his calling as a man of science.
AGW proponents denounce sceptics as conspiracy theorists; ridiculing the straw man idea that so many distinguished scientists could be induced to conspire for political ends. I have never believed in such a conspiracy. I simply believe in the human weaknesses I see every day, not least in myself. Chief among these is pride. Exalt a man for a piece of work that proves flawed and his ego-involvement will lead him astray if he is anything less than a saint. He will defend it and call in every favour from his friends to do likewise. John Harrison's enemies were sincere too. Yes, their motives were mixed. They wanted the huge prize he had so clearly earned. They wanted to maintain their respected status against the rising fame of an interloper. But they were no cartoon villains and neither are the Hockey Team. Sadly, you don't need to be Dr. Evil to hold back the advance of civilisation. You just need to be misguided and proud.
That Mann is a scientific Salieri
does not make McIntyre Mozart. He has exposed
Mann's methodological errors, but he has never purported to attempt an
alternative analysis. He has no more disproved AGW theory than Mann has
"proved" it. The Bish's excellent book merely shows that the members of the Hockey Team are (as are we all) weak humans trapped in a mesh of pride. We should not allow our distaste for their perversion of science to divert us from seeking truth. That truth will take dangerously longer to establish provisionally because of their (and their supporting politicians') unscientific interference with honest attempts to test it.
---------------* A nice moment of my life was Professor Popper's [grand-daughter][see correction in comments] (a friend of Ms Paine the Elder) spotting his books in my home and exclaiming that she had never seen copies before. But that's a story for another post.
** McIntyre, as a cursory glance at his Wikipedia biography will confirm, is far from the uneducated autodidact that Harrison was (and neither would he claim Harrison's status as a world-changing genius) but my point still stands.
