In this engrossing and accessible book, Doug Macdougall explores the causes and effects of ice ages that have gripped our planet throughout its history, from the earliest known glaciationnearly three billion years agoto the present. Following the development of scientific ideas about these dramatic events, Macdougall traces the lives of many of the brilliant and intriguing characters who have contributed to the evolving understanding of how ice ages come about. As it explains how the great Pleistocene Ice Age has shaped the earth's landscape and influenced the course of human evolution, Frozen Earth also provides a fascinating look at how science is done, how the excitement of discovery drives scientists to explore and investigate, and how timing and chance play a part in the acceptance of new scientific ideas.
Macdougall describes the awesome power of cataclysmic floods that marked the melting of the glaciers of the Pleistocene Ice Age. He probes the chilling evidence for "Snowball Earth," an episode far back in the earth's past that may have seen our planet encased in ice from pole to pole. He discusses the accumulating evidence from deep-sea sediment cores, as well as ice cores from Greenland and the Antarctic, that suggests fast-changing ice age climates may have directly impacted the evolution of our species and the course of human migration and civilization. Frozen Earth also chronicles how the concept of the ice age has gripped the imagination of scientists for almost two centuries. It offers an absorbing consideration of how current studies of Pleistocene climate may help us understand earth's future climate changes, including the question of when the next glacial interval will occur.

The book is Frozen Earth by Doug MacDougall. The book gives a good outlook on the earths history of the ice age, and what is to come in the future if we do not take care of have been and ice age, and why there was an ice age. The beginning does not tell you if all the facts are true, but as you get into the book the chapters get longer and get into more rich details about when the ice age took place, and how it created some of out valleys, mountains, and channels. The author does a great job explaining how scientists have found evidence through fossils, and land forms. Some scientist MacDougall mentions in this book have tried to prove that random boulders in the middle of valleys were put there from the glaciers melting and carrying them through out the northern half of the world into the south. Toward the end of the book it explains what is to come in the future by the way we are treating our earth by having all the green house gasses. MacDougall tells how the sea-level is rising and temperatures are getting higher and soon, everything could come to a life ice-free. I would recommend this book to anyone at the high school level that is interested in global warming and the history of ice ages. I give this book 3 out of 5.
