The authors bring a unique geological perspective to the contentious global warming issue, a view that has been notably missing far too long. Sensationalized media accounts portray climate change as abnormal and human-caused. In fact, geological science shows that climate changed in the past, it is changing now, and it will change in the future. Using an easy-to-understand question and answer format without attacking anyone's politics or motives and documenting all its conclusions with references to peer-reviewed scientific literature, the book is the authoritative, concise guide to the global warming controversy that has long been needed.
