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.

Comprehensive in scope and accessible to all reader levels, "The Encyclopedia of Global Warming Science and Technology" covers a vast range of topics, concepts, issues, processes, and scientists sifted and melded from the many scientific and technological fields. These include atmospheric chemistry, paleoclimatology, biogeography, oceanography, geophysics, glaciology, soil science, and more. Bruce E. Johansen digests the explosion of scientific work on global warming that has been published since 1980 and presents it in a set that is sure to be the indispensable standard reference work on the topic. The information here is of importance to just about everyone on the planet--for the findings of global warming science and technology should dictate the choices we make today to secure our common future. This encyclopedia will prove useful for many different types of professionals, inasmuch as global warming science informs public policy debates, applied science, and technology in such fields as energy generation, architecture, engineering, and agriculture.

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.

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

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.

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.
