This book is simply not good science, nor is it an honest review of the good science being done in this field.

Please read rebuttals from people actually doing work in climate science:

Koonin uses stale data, misinterprets it, and blows the significance of the misinterpreted data out of proportion.

In the words of Wolfgang Pauli, the arguments in this book are "not even wrong."
