McKibben is showing a lot of unprofessional dogma in this book, which I'm not a fan of. He fails to understand the complexity of climate change (I'm not denying that it exists), although his introductory chapter acknowledges the idea that things are complicated. By only citing statistics that support the agenda he would like to push, it is reminiscent of when I once did a "proof" math question using the final answer. While this analogy is slightly inaccurate to his situation where the final answer is just what he wants it to be, it does show how his science is no longer of an inquisitive manner. This type of "science" has earned a negative review from me.
