The title of this book is misleading: it should read Global Warming, because this is what the author promotes in an unambiguous fashion. He says it is the biggest issue facing Mankind, but I think there are many more pressing problems (poverty, inequality, economic depression, war and terrorism, for example). He follows the dubious advice of the various IPCC reports, but is honest enough to admit their well-known failings. Most serious of all, it is the computer models of world climate which have been criticized for their inbuilt bias and neglect of the very large effects of water vapour and aerosols (or clouds). It is these models which are at the very heart of the poor science used by Henson and the IPCC and others to justify absurd and regressive carbon taxes which will affect energy prices if they are allowed to proceed unchecked. The same or similar computer models are used for weather forecasting and we all know how unreliable they can be. Moreover, misuse of computer models lie at the heart of the ongoing financial crisis for their abuse in derivatives trading and elsewhere in the economy. The Chinese revolution is based on cheap coal, and the warmists allege that C02 is the culprit in warming the planet. The theory is quite unproven and based on a string of unverified assumptions, such as the alleged long residence time of about 100 years of the gas in the atmosphere, and the rates of production of the gas from natural and artificial sources. Other climatologists (Carter for example) argue a much shorter residence time, as one might expect since the gas is very water soluble and washed from the air very quickly. It is a greenhouse gas but much less important than water vapour, as any infra-red spectrum of air shows. On flimsy evidence, the warmists propose a drastic reduction in fossil fuel usage using carbon taxes as the preferred mechanism, despite the fact that there is no worldwide agreement. The largest countries are against it, including his own country the USA as well as most developing countries. Instead he suggest renewable energy, but they are very expensive and produce very costly power. Thus wind power is so costly that it needs vast subsidies to survive at all and is dependent on the wind blowing at specific speeds. The reader should seek help elsewhere such as in the books by Plimer Heaven and Earth: Global Warming, the Missing Science and Carter Climate: the Counter-consensus (Independent Minds) if he or she wants a balanced view of climate change.
