Most books on global warming have a particular agenda - typically either to persuade the reader of the seriousness of global warming, or to convince the reader that global warming either doesn't exist or isn't a matter of great concern. In this book Dupont has no agenda except for trying to elucidate all of the various positions that one could take on global warming. He divides this range of positions up into four different views - 'Serious Danger', 'Mild Danger', 'Denial' and 'Positive Event'. This book doesn't aim to convince you of anything, but it will be of interest if you are interested in learning about these various positions.
