The first paragraph of this accessible little book states that it will address "...who is right": the warmists or the skeptics. The concept of a clear and concise assessment of differences on scientific issues has great promise. That promise is not met.

Although the book is easy to read and understand, it ignores important scientific questions raised by other reputable scientists in peer reviewed publications. For example, the issue as to the magnitude and direction (negative or positive) of water vapor feedback is pivotal. If Dr Richard Lindzen, the internationally renowned atmospheric physicist at MIT is correct,i.e. the feedback is negative, it follows that global warming is not a significant threat.

How is this crucial subject dealt with in the book? It ignores the issue. The author simply asserts that, "Water vapor provides a positive feedback to climate change". Professor Lindzen's research results,which are supported by work of other prominent peer-reviewed scientists, are not mentioned, much less discussed.

If you are a convinced believer in catastrophic anthropogenic global warming and you want a summary of the warmist perspective, this book may be for you. But if you wish to understand the debate between believers and skeptics, you will have to look elsewhere.
