The Ice Age World

At the end of the Ice Age, small groups of hunter-gatherers crossed from Siberia to Alaska and began the last chapter in the human settlement of the earth. Many left little or no trace. But one group, the Early Paleo-Indians, exploded onto the archaeological record about 11,500 radiocarbon years ago and expanded rapidly throughout North America, sending splinter groups into Central and perhaps South America as well. Journey to the Ice Age explores the challenges faced by the Early Paleo-Indians of northeastern North America. A revealing, autobiographical account, this is at once a captivating record of Storck's discoveries and an introduction to the practice, challenges, and spirit of archaeology.

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.

A mesmerizing overview of the world as it was when glaciers covered the earth and long-extinct creatures like the woolly mammoths and saber-toothed cats battled to survive. Go back 20,000 years ago to a time of much colder global temperatures when glaciers and extensive sheets of ice covered much of our planet. As these sheets traveled, they caused enormous changes in the Earth's landscape and climate, leading to the evolution of creatures such as giant armadillos, saber-toothed cats, and woolly mammoths as well as club-wielding Neanderthals and later the cleverer modern humans. Nico Medina re-creates this harsh ancient world in a vivid and easy-to-read narrative.

Brrr…does it feel cold? Get out your gloves and get ready to experience the Ice Age! In Explore the Ice Age! with 25 Projects, readers ages 7-10 discover what an ice age consists of, why we have them, and what effect an ice age has on living organisms and ecosystems, paying particular attention to the most recent Ice Age, which is the only one humans were around to witness. About 12,000 years ago, glaciers up to 2 miles tall covered up to one-third of Earth’s land! Explore how these moving mountains of ice changed almost everything on Earth, including shorelines, weather, plants, animals and human activities, migration, and more. Learn the science and techniques of archeological and paleontological digs to understand how we know so much about a time that happened before recorded history. Science-minded activities lead readers to discover what a world covered in ice means for the earth’s crust, its atmosphere, and what happens when the planet begins to warm and the ice melts. Projects include creating mini glaciers to move mountains and create beaches and recreating the lifestyles of Paleolithic people to discover what they ate, how they hunted, how they made tools and clothes and their history in art. Don’t wait for the next ice age to get started! Cartoon illustrations, fun facts, and a compelling narrative make Explore the Ice Age! an essential part of any STEM library.

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.

The fascinating story of how a harsh terrain that resembled modern Antarctica has been transformed gradually into the forests, grasslands, and wetlands we know today.

This book tells the exciting story of the ice ages--what they were like, why they occurred, and when the next one is due. The solution to the ice age mystery originated when the National Science Foundation organized the CLIMAP project to study changes in the earth's climate over the past 700,000 years. One of the goals was to produce a map of the earth during the last ice age. Scientists examined cores of sediment from the Indian Ocean bed and deciphered a continuous history for the past 500,000 years. Their work ultimately confirmed the theory that the earth's irregular orbital motions account for the bizarre climatic changes which bring on ice ages. This is a tale of scientific discovery and the colorful people who participated: Louis Agassiz, the young Swiss naturalist whose geological studies first convinced scientists that the earth has recently passed through an ice age; the Reverend William Buckland, an eccentric but respected Oxford professor who fought so hard against the ice-age theory before accepting it; James Croll, a Scots mechanic who educated himself as a scientist and first formulated the astronomic theory of ice ages; Milutin Milankovitch, the Serbian mathematician who gave the astronomic theory its firm quantitative foundation; and the many other astronomers, geochemists, geologists, paleontologists, and geophysicists who have been engaged for nearly a century and a half in the pressing search for a solution to the ice-age mystery.

In presenting an enchanting and colorful tale of the ice age history, this book provides an informative and much-needed survey of geological history over the past 2.5 million years. Dramatic changes took place in this period both in climate and physical geographical conditions. Striking landscape features were formed and sediments were deposited which are of utmost importance for the global environment, including vegetation, animal life, and human life. Topics of the book include: evolution of the glacial theory, scientific techniques, warming and deglaciation, and early humans, among many others. Expertly written by two leading scientists who have contributed greatly to our understanding of the ice age world, the book is lavishly illustrated and contains numerous enlightening maps. It will appeal to all students and researchers involved in the earth and atmospheric sciences.
