This is an excellent guide into Climate Change. The climate discussions require no more than a high school education and a wish to know. It provides a view into how climates changed over the past two geological periods, the Pliocene and the Pleistocene, and includes what's going on in our Holocene period today. Climate science is presented in a manner that is clear and easy to understand. Today's ongoing climate debates are discussed. A parent wanting information for discussing Climate Change with their children will find this book to be very helpful.
