This is a good account of how vested interests and powerful lobbyists have consistently blocked and delayed proposals which could be essential to sustain the modern world in the 21st century. The author began his career in the oil industry but was unable to ignore the scientific facts concerning global warming and decided to employ his skills on behalf of Greenpeace. With them he was in an ideal position to observe, and contribute to, the various conferences and treaties that sought to deal with the problem of climate change. The science is well explained and it is clear that only a few maverick scientists (usually funded by the oil industry) actually dispute the probability of global warming occurring, the real argument is over whether we are doing enough to prevent a catastrophic runaway scenario taking place. The account of the different conferences and the interminable arguments over the wording of each protocol does sometimes drag, but shows the difficult and painful process that has been necessary for today's very limited agreements. Dr Leggett is better at revealing the cynical, short sighted and selfish policies adopted by the oil industry (aided and abetted by certain others) to thwart any attempt at restricting carbon emissions. They are the real villains of the piece, together with the spineless US government, and they seemed willing and able to direct the rulers of the oil producing nations to implement their wishes. They are occasionally comical, such as the Iraqui ambassador who does not believe in the existence of carbon dioxide on the grounds that it cannot be seen, or the US oil executive who believes the world is only a few thousand years old, until you realise that these sort of people are controlling the world's energy policy. It can all be slightly depressing, but it should also act as a real wake up call for us to consider the implications of our continued reliance on fossil fuel.
