An inconvenient challenge

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." Read more.
