In this eye-opening book on global warming issues, the author presents some of the scientific arguments of those scientists who are known as "deniers" of global warming. However, what becomes very clear in short order is that they are not deniers at all. In fact they freely admit that the earth has indeed warmed over the past decades/centuries. Their main point of contention, as clearly elaborated upon in this book, is that the science is not that simple and not at all settled, as many of their adversaries in this matter profess. The author's approach is to give a brief resume of the selected scientists and quote their respective scientific views. From their resumes, it is clear that these scientists are world class in their scientific fields with extremely impressive credentials and numerous peer-reviewed research publications to their names. They are scientific specialists in disciplines that are directly related to the environmental concerns under debate. Based on their extensive work, they believe that it is much too early to sound the alarm on climate change and that, most likely, the observed warming is mainly natural - possibly the continuation of a process that began at the end of the last ice age. The writing style is clear, friendly, engaging and very accessible. The many quotes from the scientists are very clear and authoritative yet free of unnecessary scientific jargon; they express their views in a plain English that any reader can understand, whatever his/her background. Consequently, this is a book that can be enjoyed by anyone. If anything, this book makes clear that scientists on both sides of this issue should get together to objectively discuss the scientific evidence and their respective interpretations with the ultimate objective of, hopefully, reaching some sort of consensus that world leaders can more reliably work with, as deemed necessary.
