Still essential reading
6 July 2017
Still essential reading despite the passage of time. This is carefully written and contains one of the clearest lay explanations of PCA and its application to correlation in climate issues that you will find. After you finish this you will accept that the Hockey Stick has no validity. The book simply demolishes it. It does not demolish the case for man made global warming.or carbon emission reduction, but it will make you think furiously about the implications for them too.
Its a bit like reading Conquest on the Soviet Terror. Its not a refutation of the idea of Communism. But after you get through understanding exactly what went on, and how well meaning liberals denied and concealed it, you will find your faith (if you ever had any) very severely in question.
Well its the same with this. Once the implications of the Hockey Stick case become clear to you, you will start to adopt a much more critical and skeptical approach to other claims made by climate activists. There is rarely, you may feel, only one cockroach, particularly when its as gigantic a specimen as this one.
