The techniques of propaganda are now well know, and Roy Spencer describes them well in his book. As a professional meteorologist, he is qualified to examine the claims of the IPCC reports (the latest from 2007) in forensic detail. At the heart of the IPCC claims is the infamous hockey stick graph synthesized by Michael Mann, and then adopted wholesale by the IPCC. They have since revised the curve as a result of severe criticism, and the modified curve now shows the Medieval warm period and the Little Ice Age in clearer perspective. Both climate diversions are well known from independent historical evidence. But as Spencer points out, the curve came from naive computer models which are in fact very poor representations of the planet's climate. They neglect many natural cycles of climate variability, and make gross assumptions which are not supported by empirical evidence at all. Such is the world of the computer modeller, and one we are already familiar with from other areas, especially financial chicanery such as the failure of Long Term Financial Management in 1998 when a faulty computer model of the economy. Its assumptions were quite wrong and the model led directly to a collapse in the markets which reverberates to this day. Similar models are widely used in the stock markets, but are failing miserably to predict share prices, resulting in huge losses to shareholders who unwisely invested in funds run by such models (the hedge fund run by MAN is one very recent example). Nevertheless, the IPCC has adopted this flawed Mann climate model and made egregious predictions of the world climate which bear no relation to reality. They have used every trick in the spin doctor's manual to push their flawed message, including endless repetition (a technique pioneered by Dr Goebbels), ad hominem attacks on anyone who questions their integrity, and outrageous claims to infallibility. A religious leader like the Pope who be proud of their behaviour! As Spencer emphasises, such behaviour is both unscientific and unethical. But yet the IPCC seems to have captured a large number of gullible politicians in its net, including most members of the current UK parliament as well as many Democrats in the USA, let along a vast horde of european politicians. They have all passed dangerous carbon tax laws which impose excruciating burdens on industry at a time when the banks are in crisis for other reasons (they also used flawed computer models to massage debt into worthless bonds), and the Euro is in imminent danger of collapse as Greece and Spain suffer from a deep recession.
But Spencer sees through all of the lies from the IPCC, and provides a much more credible picture of why and how the climate works. He suiggests that natural processes are at work in controlling the temperature of the planet, processes which are barely understood even now with our apparent endless resources in measuring key variables. The book is a must-buy for all those who follow the debates on the issues.
