A meditation on climate change, how we got there and what to do about it. As I read this book, I found many things to like about it. It is a bit long and gets tedious at times, but definitely a worthwhile read especially for discussion groups who will read and discuss it together. I highly recommend it for ongoing group discussions that are willing to divide the content into sections and talk about portions of the book at a time. That would be how to get the most of this excellent book which cites many sources as background for the author's thinking. For the general reader, reading alone, it's a bit overwhelming. Try it for your book group. You'll be glad you did.
