I actually think there's very little to say about this book, because its impact is rather obvious.
This book was dense. It was also super-important for a large variety of reasons. I knew a ton about peer review and how scientists work going in, and I did NOT know this story. This story is about how a small group of scientists obfuscated the truth about environmental problems ranging from acid rain to global warming, and they did this in a way (through the media and otherwise) that caused the public to doubt the already-proven science. It is incredibly well researched and straightforwardly written, so although it may not be easily digestible, it is eminently readable.
Over 40% of the US population still believes global warming is a hoax. I urge you all to read this book so you can know for yourself why that is utterly ridiculous and be able to inform others who may have questions or concerns.
