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.

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.

Volcanic dust, climate change, tsunamis, earthquakes—geoscience explores phenomena that profoundly affect our lives. But more than that, as Doug Macdougall makes clear, the science also provides important clues to the future of the planet. In an entertaining and accessibly written narrative, Macdougall gives an overview of Earth’s astonishing history based on information extracted from rocks, ice cores, and other natural archives. He explores such questions as: What is the risk of an asteroid striking Earth? Why does the temperature of the ocean millions of years ago matter today? How are efforts to predict earthquakes progressing? Macdougall also explains the legacy of greenhouse gases from Earth’s past and shows how that legacy shapes our understanding of today’s human-caused climate change. We find that geoscience in fact illuminates many of today’s most pressing issues—the availability of energy, access to fresh water, sustainable agriculture, maintaining biodiversity—and we discover how, by applying new technologies and ideas, we can use it to prepare for the future.

Climate change is a major topic of concern today, scientifically, socially, and politically. It will undoubtedly continue to be so for the foreseeable future, as predicted changes in global temperatures, rainfall, and sea level take place, and as human society adapts to these changes. In this remarkable new work, Jan Zalasiewicz and Mark Williams demonstrate how the Earth's climate has continuously altered over its 4.5 billion-year history. The story can be read from clues preserved in the Earth's strata - the evidence is abundant, though always incomplete, and also often baffling, puzzling, infuriating, tantalizing, seemingly contradictory. Geologists, though, are becoming ever more ingenious at interrogating this evidence, and the story of the Earth's climate is now being reconstructed in ever-greater detail - maybe even providing us with clues to the future of contemporary climate change. The history is dramatic and often abrupt. Changes in global and regional climate range from bitterly cold to sweltering hot, from arid to humid, and they have impacted hugely upon the planet's evolving animal and plant communities, and upon its physical landscapes of the Earth. And yet, through all of this, the Earth has remained consistently habitable for life for over three billion years - in stark contrast to its planetary neighbours. Not too hot, not too cold; not too dry, not too wet, it is aptly known as 'the Goldilocks planet'.

"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.

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.

Earth's past is littered with the mysterious and unexplained: the pyramids, Easter Island, Stonehenge, dinosaurs, and the list goes on and on as science looks for clues to decipher these puzzles. One such mystery surrounds the now-extinct creature called the woolly mammoth. Author and meteorologist Michael Oard has studied the mammoth and its equally mysterious time period, the Ice Age, for many years and has come to some fascinating conclusions to help lift the fog engulfing the facts. Some of the questions he addresses include: What would cause the summer temperatures of the northern United States and European to plummet more than 50 degrees Fahrenheit? Why did mammoths become extinct across the entire earth at the same time as many other large mammals? Why are the mammoth carcasses found generally in standing positions? How could large lakes exist in what are today very dry, desert-like places? What was the source of the abnormal of moisture necessary for heavy snow? What caused the cold summer temperatures and heavy snowfall to persist for hundreds of years? In logical progression many other Ice Age topics are explained including super Ice Age floods, ice cores, man in the Ice Age, and the number of ice ages. This is one of the most difficult eras in geological history for a uniformitarian scientist (one who believes the earth evolved by slow processes over millions of years) to explain, simply because long ages of evolution cannot explain it. Provided here are plausible explanations of the seemingly unsolvable mysterious about the Ice Age and the woolly mammoths - Frozen in Time.

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

Natural history, the deliberate observation of the environment, is arguably the oldest science. From purely practical beginnings as a way of finding food and shelter, natural history evolved into the holistic, systematic study of plants, animals, and the landscape. Deep Things out of Darkness chronicles the rise, decline, and ultimate revival of natural history within the realms of science and public discourse. Ecologist John G. T. Anderson focuses his account on the lives and contributions of an eclectic group of men and women, from John Ray, John Muir, Charles Darwin, and Rachel Carson, who endured remarkable hardships and privations in order to learn more about their surroundings. Written in an engaging narrative style and with an extensive bibliography of primary sources, the book charts the journey of the naturalist’s endeavor from prehistory to the present, underscoring the need for natural history in an era of dynamic environmental change.

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.

Many thinkers believe that the next transformational change in human organization will be the onset of human-level artificial intelligence (the 'singularity'), and that the most likely method of achieving this will come through brain emulations or "ems": the ability to scan human brains and program their connections into ever faster computers. Taking this as his starting point, Hanson describes what a world dominated by these ems will be like.
