Illuminating and insightful, but undoubtedly biased in its treatment of the "Hockey Stick" debate. In my mind, this isn't a book about global warming, but a book about the corruptibility of the scientific process, human fallibility, and the disconnect between scientists, politicians, the media, and the public. In both senses, Montford argues effectively, but his skeptical, alarmist rhetoric is still hard to ignore.
Montford does a good job of detailing some of the complex arguments that go into the debate. Some of the statistics got a little involved, but as a student involved in university-level research, I found it to be an enlightening and necessary part of the story. The book is well-written and engaging, even to someone with little prior knowledge of the topic.
