In this book Donald Rapp provides a balanced assessment of global warming, tending neither to the views of alarmists or nay-sayers. Rapp has the ability to move into a highly technical field, assimilate the content, organize the knowledge base and succinctly describe the field, its content, its unresolved issues and achievements. This is precisely what he does in this book in relation to global climate change. As such his approach is refreshingly different.
