I hoped when reading this book that the author would enlighten my lack of knowledge of climate models, but was deeply disappointed. He starts by asserting that all we know about the climate of the earth, now and in the past, is based on mathematical models. This is demonstrably untrue, because we have vast archives of information produced before any computer models were available or used. Although accurate instrumental records are sparse before the late Victorian period, there is much comment in historic works of which this author is either blissfully ignorant, or deliberately deceitful. We also have extensive archaeological knowledge of past civilizations, much of it of recent origin. And that data is important because it has exposed the sham of computer models used to generate false predictions of the future climate and even the past climate. The best example is the attempt by Mann and Jones to re-invent history by airbrushing the Medieval Warm Period and the Little Ice Age from the historic record. That these periods were real is proved, for example, by the extant remains of the Viking discovery of North America such as the Lanse-aux-Meadows settlement dated to about 1000 AD on Newfoundland by Helge Ingstad. Indeed, the climate then was warm enough to allow crops on Greenland and the waters around were ice-free, allowing the Vikings freedom of passage. This was of course when CO2 levels in the air were low, and well before the Industrial Revolution. The glib assertion that heightened CO2 from coal-burning power stations (for example) levels have caused global warming and threaten the planet is as bogus as the computer models used to justify the hypothesis.
It is mis-applied computer models we now know we have to blame for many other world problems. especially the ongoing banking crisis, where such models were used to deceive not just investors but many financial institutions and governments too. We first came across their misuse in the failure of Long Term Capital Management in 1998, when vast sums of money were lost because a computer model was wrong. It was based on flawed assumptions about the economy, but yet the geeks have not faltered in continuing their misdeeds, currently in falsely predicting a dismal future (floods, extreme weather, hurricanes etc etc). None have occurred, and indeed more lives have been lost by tsunamis than any weather events. The climate appears now and for the past decade to have been cooling, not heating, which must raise questions over their validity. Our valiant author ignores the real evidence and seems hellbent on pushing outdated ideas. Avoid this book.
