Book Description
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 glaciation—nearly three billion years ago—to 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.

Book Description
Until about 13,000 years ago, North America was home to a menagerie of massive mammals. Mammoths, camels, and lions walked the ground that has become Wilshire Boulevard in Los Angeles and foraged on the marsh land now buried beneath Chicago's streets. Then, just as the first humans reached the Americas, these Ice Age giants vanished forever. In Once and Future Giants, science writer Sharon Levy digs through the evidence surrounding Pleistocene large animal ("megafauna") extinction events worldwide, showing that understanding this history--and our part in it--is crucial for protecting the elephants, polar bears, and other great creatures at risk today. These surviving relatives of the Ice Age beasts now face the threat of another great die-off, as our species usurps the planet's last wild places while driving a warming trend more extreme than any in mammalian history. Deftly navigating competing theories and emerging evidence, Once and Future Giants examines the extent of human influence on megafauna extinctions past and present, and explores innovative conservation efforts around the globe. The key to modern-day conservation, Levy suggests, may lie fossilized right under our feet.

Book Description
Only in the last decade have climatologists developed an accurate picture of yearly climate conditions in historical times. This development confirmed a long-standing suspicion: that the world endured a 500-year cold snap -- The Little Ice Age -- that lasted roughly from A.D. 1300 until 1850. The Little Ice Age tells the story of the turbulent, unpredictable and often very cold years of modern European history, how climate altered historical events, and what they mean in the context of today's global warming. With its basis in cutting-edge science, The Little Ice Age offers a new perspective on familiar events. Renowned archaeologist Brian Fagan shows how the increasing cold affected Norse exploration; how changing sea temperatures caused English and Basque fishermen to follow vast shoals of cod all the way to the New World; how a generations-long subsistence crisis in France contributed to social disintegration and ultimately revolution; and how English efforts to improve farm productivity in the face of a deteriorating climate helped pave the way for the Industrial Revolution and hence for global warming. This is a fascinating, original book for anyone interested in history, climate, or the new subject of how they interact.

Book Description
More than 12,000 years ago, in one of the greatest triumphs of prehistory, humans colonized North America, a continent that was then truly a new world. Just when and how they did so has been one of the most perplexing and controversial questions in archaeology. This dazzling, cutting-edge synthesis, written for a wide audience by an archaeologist who has long been at the center of these debates, tells the scientific story of the first Americans: where they came from, when they arrived, and how they met the challenges of moving across the vast, unknown landscapes of Ice Age North America. David J. Meltzer pulls together the latest ideas from archaeology, geology, linguistics, skeletal biology, genetics, and other fields to trace the breakthroughs that have revolutionized our understanding in recent years. Among many other topics, he explores disputes over the hemisphere's oldest and most controversial sites and considers how the first Americans coped with changing global climates. He also confronts some radical claims: that the Americas were colonized from Europe or that a crashing comet obliterated the Pleistocene megafauna. Full of entertaining descriptions of on-site encounters, personalities, and controversies, this is a compelling behind-the-scenes account of how science is illuminating our past.

Book Description
Cro-Magnons were the first fully modern Europeans--not only the creators of the stunning cave paintings at Lascaux and elsewhere, but the most adaptable and technologically inventive people that had yet lived on earth. The prolonged encounter between theCro-Magnons and the archaic Neanderthals, between 45,000 and 30,000 years ago, was one of the defining moments of history. The Neanderthals survived for some 15,000 years in the face of the newcomers, but were finally pushed aside by the Cro-Magnons' vastly superior intellectual abilities and cutting-edge technologies. What do we know about this remarkable takeover? Who were these first modern Europeans and what were they like? How did they manage to thrive in such an extreme environment? And what legacydid they leave behind them after the cold millennia? This is the story of a little known, yet seminal, chapter of human experience.--From publisher description.
