Explores the causes and effects of ice ages, explains how the Pleistocene Ice Age has shaped the earth's landscape and influenced human evolution, and offers authoritative speculation and explanations of future climate changes, their causes, and their impact on both the natural world and human civilization.
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.
"It's impossible to grasp the whole planet or integrate all the descriptions of it. But because we live here, we have to try. This is not just an artistic compulsion or an existential yearning, still less an academic exercise. It's a survival issue. This is the only planet we have. We're stuck here, and we don't own the place-it would be the height of arrogance to assume that we do. We're tenants here, not owners, but we're tenants with hope for a long-term tenancy. We want to extend our lease just as far as we can."-from Earth: A Tenant's Manual In Earth: A Tenant's Manual, the distinguished geologist Frank H. T. Rhodes, President Emeritus of Cornell University, provides a sweeping, accessible, and deeply informed guide to the home we all share, showing us how we might best preserve the Earth's livability for ourselves and future generations. Rhodes begins by setting the scene for our active planet and explaining how its location and composition determine how the Earth works and why it teems with life. He emphasizes the changes that are of concern to us today, from earthquakes to climate change and the clashes over the energy resources needed for the Earth's exploding population. He concludes with an extended exploration of humanity's prospects on a complex, protean, and ultimately finite world. It is not a question of whether the planet is sustainable; the challenge facing life on Earth-and the life of the Earth-is whether an expanding and high-consumption species like ours is sustainable. Only new resources, new priorities, new policies and, most of all, new knowledge, can reverse the damage that humanity is doing to our home-and ourselves. A sustainable human future, Rhodes concludes in this eloquent, sobering, but ultimately optimistic book, will require a sense of responsible stewardship, for we are not owners of this planet; we are tenants. Surveying the systems, large and small, that govern Earth's processes and influence its changes, Rhodes addresses the negative consequences of human activities for the health of its regulatory systems but offers practical suggestions as to how we might effect repairs, or at least limit further damage to our home.
Eerie, fascinating, and often moving, these tales of geologic history and human fortitude and folly will stay with you long after you put the book down.
From the opening and closing of oceans over millions of years to the overnight reshaping of landscapes by volcanoes, the Earth beneath our feet is constantly changing. The Rough Guide to the Earth explores all aspects of our dynamic planet, from the planet’s origins and evolution and the seasons and tides to melting ice caps, glaciers and climate change. Featuring many spectacular images and helpful diagrams, this Rough Guide provides a fascinating and accessible introduction to Earth science.
Understand major developments of human prehistory People of the Earth: An Introduction to World Prehistory 14/e, provides an exciting journey though the 7-million-year-old panorama of humankind's past. This internationally renowned text provides the only truly global account of human prehistory from the earliest times through the earliest civilizations. Written in an accessible way for beginning students, People of the Earth shows how today's diverse humanity developed biologically and culturally over millions of years against a background of constant climatic change.
Why do we keep talking about so many environmental problems and rarely solve any? If these are scientific issues, then why can't scientists solve them or at least agree on what to do? In his new book, The Moon in the Nautilus Shell, ecologist Daniel Botkin explains why. For one thing, although we live in a world of constantly changing environments and talk a lot about climate change, most of our environmental laws, policies, and scientific premises are based on the idea that the environment is constant, never changing, except when people affect it. For another, we have lost contact with nature in personal ways. Disconnected from our surroundings, we lack the deep understanding and feelings about the environment to make meaningful judgments. The environment has become just another one of those special interests that interferes with our lives. Poised to be a core text of the twenty-first century environmental movement, The Moon in the Nautilus Shell challenges us to think critically about our role in nature.
The West without Water documents the tumultuous climate of the American West over twenty millennia, with tales of past droughts and deluges and predictions about the impacts of future climate change on water resources. Looking at the region’s current water crisis from the perspective of its climate history, the authors ask the central question of what is "normal" climate for the West, and whether the relatively benign climate of the past century will continue into the future. The West without Water merges climate and paleoclimate research from a wide variety of sources as it introduces readers to key discoveries in cracking the secrets of the region’s climatic past. It demonstrates that extended droughts and catastrophic floods have plagued the West with regularity over the past two millennia and recounts the most disastrous flood in the history of California and the West, which occurred in 1861–62. The authors show that, while the West may have temporarily buffered itself from such harsh climatic swings by creating artificial environments and human landscapes, our modern civilization may be ill-prepared for the future climate changes that are predicted to beset the region. They warn that it is time to face the realities of the past and prepare for a future in which fresh water may be less reliable.
This e-book has a life that began with 28 pages of recommendations to a high school teacher who requested ways of addressing a publishers three questions on the Neo-Evolution vs. Creation debate. This was in May 2005. Since then I expanded similar Q&As in various media, participated in public debates (2007-2009). I look back to the successful high level Evolution vs. Creation debates that were held during the 1970s and early 1980s. Dr. Henry M. Morris and Dr. Duane T. Gish had used their newly developed Creation Scientific Model to challenge those who defended the Evolution Scientific Model. The Debates format was very constructive and contributed strategically in addressing many key issues that required further clarification. The debaters were well prepared and well-disciplined and even if some of the debaters appeared to have lost in this round, the debate exercise itself helped to rejuvenate the debaters and the audience thus helping them to energize and look forward towards the next round of the continuing series of debates
