Christian Gerondeau is a militant heretic in a world which has adopted a new religion - saving the planet from global warming by reducing CO2 emissions. His argument is that most CO2 is produced by burning fossil fuel and the great delusion is that we can do anything to reduce it. Developing countries (which account for half the CO2 but produce per person a tenth as much as developed countries) aspire to western lifestyles which we wish to maintain. Oil, coal and gas will be used until supplies are exhausted. Atmospheric CO2 will therefore more than double this century from its 1900 level of 2000 billion tons. He reviews the pronouncements and publications of the prophets of the new religion and concludes that it is far from certain that even this will produce harmful climate change. Though not averse to efficient use of fuel he thinks all the measures adopted to reduce CO2 are science fiction which will make Europe uncompetitive and distract from other priorities like relief of hunger. He is particularly unimpressed by windmills as a power source (displacing supermarkets as the cathedrals of our time perhaps?). Consensus is part of religion rather than science and those who do not accept it are likely to remain unheard. The author is an engineer who has advised governments on traffic problems. The writing is crisp, combative and comprehensible, with a list of questions at the beginning and a summary of his conclusions at the end. Climate change sceptics will like this book.
