This book was my big summer read and I'm a great fan of it. Particularly good if you want to know the state of the science on climate change (second edition published January 2008), whether it's studies on why air travel is so damaging, to the massive upwards uncertainties about how fast the Arctic is melting and how high sea levels could rise. I work on some aspects of climate change but needed a much broader overview - this book has given it to me in an accessible way. The tone is balanced rather than polemical and packed full of information. The visuals and the writing style are great and break it down into bite-sized chunks. It shows you how big the challenge is, and it also takes you clearly through the steps that governments and economies will need to make, and the climate reasons why the timetable is tough. The steps on individual action are not really the focus of this book but are very practical.
