Will temperatures rise by 2�C or 8�C over the next hundred years? Will sea levels rise by 2 or 30 feet? The only way that we can accurately answer questions like these is by looking into the distant past, for a comparison with the world long before the rise of mankind.We may currently believe that atmospheric shifts, like global warming, result from our impact on the planet, but the earth's atmosphere has been dramatically shifting since its creation. This book reveals the crucial role that plants have played in determining atmospheric change - and hence the conditions on the planet we know today. Along the way a number of fascinating puzzles arise: Why did plants evolve leaves? When and how did forests once grow on Antarctica? How did prehistoric insects manage to grow so large? The answers show the extraordinary amount plants can tell us about the history of the planet -- something that has often been overlooked amongst the preoccuputations with dinosaur bones and animal fossils.David Beerling's surprising conclusions are teased out from various lines of scientific enquiry, with evidence being brought to bear from fossil plants and animals, computer models of the atmosphere, and experimental studies. Intimately bound up with the narrative describing the dynamic evolution of climate and life through Earth's history, we find Victorian fossil hunters, intrepid polar explorers and pioneering chemists, alongside wallowing hippos, belching volcanoes, and restless landmasses.

    The chapters forming the bulk of this report describe scientists assessment of the state-of-knowledge in their respective fields. The report will be highly relevant as Governments and industry consider their options for moving forward together to address the challenge of climate change. (Includes CD-ROM)

    Cynthia Barnett does it by telling us the stories of the amazing personalities behind our water wars, the stunning contradictions that allow the wettest state to have the most watered lawns, and the thorough research that makes her conclusions inescapable. Barnett has established herself as one of Florida’s best journalists and Mirage is a must-read for anyone who cares about the future of the state.”—Mary Ellen Klas, Capital Bureau Chief, Miami Herald “Mirage is the finest general study to date of the freshwater-supply crisis in Florida. Well-meaning villains abound in Cynthia Barnett’s story, but so too do heroes, such as Arthur R. Marshall Jr., Nathaniel Reed, and Marjorie Harris Carr. The author’s research is as thorough as her prose is graceful. Drinking water is the new oil. Get used to it.”—Michael Gannon, Distinguished Professor of history, University of Florida, and author of Florida: A Short History “With lively prose and a journalist’s eye for a good story, Cynthia Barnett offers a sobering account of water scarcity problems facing Florida—one of our wettest states—and the rest of the East Coast. Drawing on lessons learned from the American West, Mirage uses the lens of cultural attitudes about water use and misuse to plead for reform. Sure to engage and fascinate as it informs.”—Robert Glennon, Morris K. Udall Professor of Law and Public Policy, University of Arizona, and author of Water Follies: Groundwater Pumping and the Fate of America’s Fresh Waters Part investigative journalism, part environmental history, Mirage reveals how the eastern half of the nation—historically so wet that early settlers predicted it would never even need irrigation—has squandered so much of its abundant freshwater that it now faces shortages and conflicts once unique to the arid West. Florida’s parched swamps and supersized residential developments set the stage in the first book to call attention to the steady disappearance of freshwater in the American East, from water-diversion threats in the Great Lakes to tapped-out freshwater aquifers along the Atlantic seaboard. Told through a colorful cast of characters including Walt Disney, Jeb Bush and Texas oilman Boone Pickens, Mirage ferries the reader through the key water-supply issues facing America and the globe: water wars, the politics of development, inequities in the price of water, the bottled-water industry, privatization, and new-water-supply schemes. From its calamitous opening scene of a sinkhole swallowing a house in Florida to its concluding meditation on the relationship between water and the American character, Mirage is a compelling and timely portrait of the use and abuse of freshwater in an era of rapidly vanishing natural resources.

    Alvarez had the first glimmer of that amazing insight when he noticed something odd in a rock outcrop in central Italy. Alvarez now returns to that rich terrain, this time to take the reader on an excavation of the Earth's distant past. We encounter the volcanoes that formed the Seven Hills of Rome; the majestic limestone Apennine mountains that started to develop millions of years ago under water; the evidence that the Mediterranean Sea completely evaporated to a sunken desert, perhaps several times; and the proof that continental plates once overran one another to form the Alps. In Alvarez's telling, all major geologic episodes are as dramatic as the great impact that killed the dinosaurs, even when they happen over eons and without huge creatures to witness them.

    Unseen by most of us, they are providing information on the many changes taking place, from movements in the land and volcanic eruptions, to human-caused changes such as the growth of cities, deforestation and the spread of pollutants in the atmosphere and oceans. Led by four editors with support from a production team at NASA Goddard Space Flight Center, many of the world's top remote sensing scientists showcase some spectacular and beautiful satellite imagery along with informed essays on the science behind these images and the implications of what is shown. This is a stunningly attractive and informative book for anyone interested in environmental issues and the beauty of our home planet, providing inspiration for students, teachers, environmentalists and the general public alike.

    In this compelling, accessible, and elegantly reasoned new book, award-winning scholar and researcher Chris Impey explores the foundations of this rapidly developing discipline, where it’s going, and what it’s likely to find. The journey begins with the earliest steps of science, gaining traction through the revelations of the Renaissance, including Copernicus’s revolutionary declaration that the Earth was not the center of the universe but simply a planet circling the sun. But if Earth is not the only planet, it is so far the only living one that we know of. In fascinating detail, The Living Cosmos reveals the incredible proliferation and variety of life on Earth, paying special tribute to some of its hardiest life forms, extremophiles, a dizzying array of microscopic organisms compared, in Impey’s wise and humorous prose, to superheroes that can survive extreme heat and cold, live deep within rocks, or thrive in pure acid.From there, Impey launches into space, where astrobiologists investigate the potential for life beyond our own world. Is it to be found on Mars, the “death planet” that has foiled most planetary missions, and which was wet and temperate billions of years ago? Or on Venus, Earth’s “evil twin,” where it rains sulfuric acid and whose heat could melt lead? (“Whoever named it after the goddess of love had a sorry history of relationships.”) The answer may lie in a moon within our Solar System, or it may be found in one of the hundreds of extra-solar planets that have already been located. The Living Cosmos sees beyond these explorations, and imagines space vehicles that eschew fuel for solar- or even nuclear-powered rockets, all sent by countries motivated by the millions to be made in space tourism.But The Living Cosmos is more than just a riveting work about experiment and discovery. It is also an affecting portrait of the individuals who have devoted their lives to astrobiology. Illustrated throughout, The Living Cosmos is a revelatory book about a science that is changing our view of the universe, a mesmerizing guide to what life actually means and where it may–or may not–exist, and a stunning work that explains our past as it predicts our future.

    Planetary science provides an opportunity for these students to apply a wide range of subject matter pertaining to the Earth to the study of other planets and their principal satellites. In this way, planetary science tends to unify subjects in the Earth Sciences that are traditionally taught separately. Therefore, planetary science is well-suited to be taught as a capstone course for senior undergraduates in geology departments and as an introduction to the solar system in astronomy departments. Both groups of students will benefit because planetary science bridges the gap between geology and astronomy and it prepares geologists and astronomers to participate actively in the on-going exploration of the solar system.The subject matter is presented in 24 chapters that lead the reader through the solar system starting with historical perspectives on space exploration and the development of the scientific method. The presentations concerning the planets and their satellites emphasize that their origin and subsequent evolution can be explained by applications of certain basic principles of physics, chemistry, and celestial mechanics and that the surface features of the solid bodies in the solar system can be interpreted by means of the principles of geology.
