That evidence, he argues, shows that 700 million years ago the Earth did indeed freeze over completely, becoming a giant “snowball,” in the worst climatic catastrophe in history. Even more startling is his assertion that, instead of ending life on Earth, this global deep freeze was the trigger for the Cambrian Explosion, the hitherto unexplained moment in geological time when a glorious profusion of complex life forms first emerged from the primordial ooze.In a story full of intellectual intrigue, we follow the irascible but brilliant Hoffman and a supporting cast of intrepid geologists as they scour the planet, uncovering clue after surprising clue. We travel to a primeval lagoon at Shark Bay in western Australia, where dolphins cavort with swimmers every morning at seven and “living rocks” sprout out of the water like broccoli heads; to the desolate and forbidding ice fields of a tiny Arctic archipelago seven hundred miles north of Norway; to the surprising fossil beds that decorate Newfoundland’s foggy and windswept coastline; and on to the superheated salt pans of California’s Death Valley.Through the contours of these rich and varied landscapes Walker teaches us to read the traces of geological time with expert eyes, and we marvel at the stunning feats of resilience and renewal our remarkable planet is capable of. Snowball Earth is science writing at its most gripping and enlightening.

    World-renowned dinosaur illustrator and researcher Gregory Paul provides comprehensive visual and textual coverage of the great Mesozoic animals that gave rise to the living dinosaurs, the birds. Incorporating the new discoveries and research that are radically transforming what we know about dinosaurs, this book is distinguished both by its scientific accuracy and the quality and quantity of its illustrations. It presents thorough descriptions of more than 735 dinosaur species and features more than 600 color and black-and-white images, including unique skeletal drawings, life studies, and scenic views--illustrations that depict the full range of dinosaurs, from small, feathered creatures to whale-sized supersauropods.Heavily illustrated species accounts of the major dinosaur groups are preceded by an extensive introduction that covers dinosaur history and biology, the extinction of nonavian dinosaurs, the origin of birds, and the history of dinosaur paleontology--and that also gives a taste of what it might be like to travel back to the time of the dinosaurs.The Princeton Field Guide to Dinosaurs is a must-have for anyone who loves dinosaurs, from the amateur enthusiast to the professional paleontologist.The first authoritative field guide to dinosaursCovers more than 735 speciesBeautiful, large-format volumeLavishly illustrated throughout, with more than 600 color and black-and-white drawings and figures, including: More than 130 color life studies, including scenic views Close to 450 skeletal, skull, head, and muscle drawings 8 color paleo-distribution maps Color timelineDescribes anatomy, physiology, locomotion, reproduction, and growth of dinosaurs, as well as the origin of birds and the extinction of nonavian dinosaurs

    They have also become vibrant educational centers, full of engaging exhibits that share those discoveries with students and an enthusiastic general public.   At the heart of it all from the very start have been curators. Yet after three decades as a natural history curator, Lance Grande found that he still had to explain to people what he does. This book is the answer—and, oh, what an answer it is: lively, exciting, up-to-date, it offers a portrait of curators and their research  like none we’ve seen, one that conveys the intellectual excitement and the educational and social value of curation. Grande uses the personal story of his own career—most of it spent at Chicago’s storied Field Museum—to structure his account as he explores the value of research and collections, the importance of public engagement, changing ecological and ethical considerations, and the impact of rapidly improving technology. Throughout, we are guided by Grande’s keen sense of mission, of a job where the why is always as important as the what.   This beautifully written and richly illustrated book is a clear-eyed but loving account of natural history museums, their curators, and their ever-expanding roles in the twenty-first century.

    Mark Plaster takes readers beyond the ambulance bay doors into the stranger-than-fiction world of the Emergency Department. By turns heart-warming and gut-wrenching, "Night Shift" chronicles the ebb and flow of human life, in all of its unvarnished glory, as it passes through the doors of the ED.

    These first geologists were made up primarily, and inevitably, of gentlemen with the necessary wealth to support their interests, yet boosting their numbers, expanding their learning and increasing their findings were clergymen, academics – and women. This lively and eclectic collection of characters brought passion, eccentricity and towering intellect to geology and Brenda Maddox in Reading the Rocks does them full justice, bringing them to vivid life. The new science of geology was pursued by this assorted band not only because they loved it but also because it opened a window on Earth's ancient past. They showed great courage in facing the conflict between geology and Genesis that immediately presented itself: for the rocks and fossils being dug up showed that the Earth was immeasurably old, rather than springing from a creation made in the six days that the Bible claimed. Moreover, the fossil evidence revealed upward progress in the changing forms of life. It is no coincidence that Charles Darwin was a keen geologist.The individual stories of these first geologists, their hope and fears, triumphs and disappointments, the theological, philosophical and scientific debates their findings provoked, and the way that as a group, they were to change irrevocably and dramatically our understanding of the world is told by Brenda Maddox with a storyteller's skill and a fellow scientist's understanding. The effect is absorbing, revelatory and strikingly original. - See more at: http://www.bloomsbury.com/uk/reading-...

    Bercovici marries humor and legitimate scientific intrigue, rocketing readers across nearly fourteen billion years and making connections between the essential theories that give us our current understanding of topics as varied as particle physics, plate tectonics, and photosynthesis. Bercovici’s unique literary endeavor is a treasure trove of real, compelling science and fascinating history, providing both science lovers and complete neophytes with an unforgettable introduction to the fields of cosmology, geology, genetics, climate science, human evolution, and more.

    This claim is not only false, but its presence in the debate is an insult to science." With these words, the authors begin a detailed analysis of one of the most controversial topics of the day. The authors make a compelling case against claims of a scientific consensus. The purported proof of such a consensus consists of sloppy research by nonscientists, college students, and a highly partisan Australian blogger. Surveys of climate scientists, even those heavily biased in favor of climate alarmism, find extensive disagreement on the underlying science and doubts about its reliability. The authors point to four reasons why scientists disagree about global warming: a conflict among scientists in different and often competing disciplines; fundamental scientific uncertainties concerning how the global climate responds to the human presence; failure of the United Nations Intergovernmental Panel on Climate Change (IPCC) to provide objective guidance to the complex science; and bias among researchers. The authors offer a succinct summary of the real science of climate change based on their previously published comprehensive review of climate science in a volume titled Climate Change Reconsidered II: Physical Science. They recommend that policymakers resist pressure from lobby groups to silence scientists who question the authority of the IPCC to claim to speak for climate science. More than 50,000 copies of the first edition were sold or given away in five months to elected officials, civic and business leaders, scientists, and other opinion leaders. The response from the science community and experts on climate change has been overwhelmingly positive. To meet demand for more copies, we have produced this second revised edition. Changes include a foreword by Marita Noon, at the time executive director of Energy Makes America Great, Inc. Some of the discussion in Chapter 1 has been revised and expanded thanks to feedback from readers of the first edition. Graphs in Chapters 4, 5, and 6 are now full color, and new graphs have been added.

    Turner's clear, insightful prose and Anton's masterly illustrations combine to offer specialists and newcomers alike an accurate and accessible guide to the evolution of cats.

    Many were fantastic, bizarre creatures that still capture our imagination: the super-predator Tyrannosaurus, the plate-backed Stegosaurus, and the long-necked, long-tailed Diplodocus. Dinosaurs: The Ultimate Guide to How They Lived taps into our enduring interest in dinosaurs, shedding new light on different dinosaur groups. Leading paleontology experts Darren Naish and Paul Barrett trace the evolution, anatomy, biology, ecology, behavior, and lifestyle of a variety of dinosaurs. They also remind us that dinosaurs are far from extinct: they present evidence supporting the evolution of dinosaurs to birds that exist today as approximately ten thousand different species. Throughout their narrative Naish and Barrett reveal state-of-the-art new findings shaping our understanding of dinosaurs. Readers will discover, for example, how the use of CT-scanning enables scientists to look inside dinosaur skulls, thus gaining new insight into their brains and sense organs. Dinosaurs is a must-have for all those wanting to keep up to date about these dynamic, complicated creatures.

    But how much do these types of entertainment really tell us about recent scientific discoveries and the latest research into the world of the dinosaur?This is the first book explain how scientists have been able to put together a picture of how dinosaurs looked, what they ate, and how they moved and interacted with each other. Taking a new approach to the subject, David Norman combines different areas of science, such as anatomy, genetics, forensics, and engineering design, to piece together the latest evidence of how animal life evolved on earth. Norman engagingly lays out the history of dinosaur research, from the speculation over ancient myths about dragons, to the latest virtual reality animation sequences and engineering design analysis. He also discusses the role that informed speculation and luck has played in many of the major discoveries.This book is a fantastic introduction for those just beginning to take an interest in dinosaurs and a must-read for true dinosaur-lovers who want to know not just the latest theories and discoveries, but how scientists achieved them.

    Chief among these naysayers was the French Count and world-renowned naturalist Georges-Louis Leclerc de Buffon, who wrote that the flora and fauna of America (humans included) were inferior to European specimens. Thomas Jefferson—author of the Declaration of Independence, U.S. president, and ardent naturalist—spent years countering the French conception of American degeneracy. His Notes on Virginia systematically and scientifically dismantled Buffon’s case through a series of tables and equally compelling writing on the nature of his home state. But the book did little to counter the arrogance of the French and hardly satisfied Jefferson’s quest to demonstrate that his young nation was every bit the equal of a well-established Europe. Enter the giant moose. The American moose, which Jefferson claimed was so enormous a European reindeer could walk under it, became the cornerstone of his defense. Convinced that the sight of such a magnificent beast would cause Buffon to revise his claims, Jefferson had the remains of a seven-foot ungulate shipped first class from New Hampshire to Paris. Unfortunately, Buffon died before he could make any revisions to his Histoire Naturelle, but the legend of the moose makes for a fascinating tale about Jefferson’s passion to prove that American nature deserved prestige. In Mr. Jefferson and the Giant Moose, Lee Alan Dugatkin vividly recreates the origin and evolution of the debates about natural history in America and, in so doing, returns the prize moose to its rightful place in American history.

    It also contains one of the world's largest supplies of natural gas, a resource that has been dismissed as inaccessible until recently. Technological developments that combine horizontal drilling with hydraulic fracturing ("fracking") have removed physical and economic barriers to extracting hundreds of trillions of cubic feet of gas from bedrock deep below the Appalachian basin. Beginning in 2006, the first successful Marcellus gas wells by Range Resources, combined with a spike in the value of natural gas, spurred a modern-day gold rush a "gas rush" with profound ramifications for environmental policy, energy markets, political dynamics, and the lives of the people living in the Marcellus region. Under the Surface is the first book-length journalistic overview of shale gas development and the controversies surrounding it.Control over drilling rights is at stake in the heart of Marcellus country northeast Pennsylvania and central New York. The decisions by landowners to work with or against the companies and the resulting environmental and economic consequences are scrutinized by neighbors faced with similar decisions, by residents of cities whose water supply originates in the exploration area, and by those living across state lines with differing attitudes and policies concerning extraction industries. Wilber's evenhanded treatment gives a voice to all constituencies, including farmers and landowners tempted by the prospects of wealth but wary of the consequences, policymakers struggling with divisive issues, and activists coordinating campaigns based on their respective visions of economic salvation and environmental ruin. Wilber describes a landscape in which the battle over the Marcellus ranges from the very local yard signs proclaiming landowners' allegiances for or against shale gas development to often conflicting municipal, state, and federal legislation intended to accelerate, delay, or discourage exploration.For millions of people with a direct stake in shale gas exploration in the Marcellus or any number of other emerging shale resources in the United States and worldwide, or for those concerned about the global energy outlook, Under the Surface offers a worthwhile and engaging look at the issues.

    However, their impact has not been limited to debates about geology and evolution: attempts to explain their existence has shaken religion at its very roots, and they have remained a subject of ceaseless fascination for people of all ages and backgrounds. In this readable and wide-ranging book, Keith Thomson provides a remarkably all-encompassing explanation of fossils as a phenomenon. How did Darwin use fossils to support his theory of evolution? What are living fossils? What fossils will we leave behind for future generations to examine? Beyond the scientific aspects, Thomson highlights the impact of fossils on philosophy and mythology, our concept of time, and today's popular culture. From the black market to the Piltdown Man, and from mythological dragons to living dinosaurs, fossils hold a permanent place in the popular imagination.
