In what has become one of science's greatest riddles, these large animals vanished in North and South America around the time humans arrived at the end of the last great ice age. Part paleontological adventure and part memoir, Twilight of the Mammoths presents in detail internationally renowned paleoecologist Paul Martin's widely discussed and debated "overkill" hypothesis to explain these mysterious megafauna extinctions. Taking us from Rampart Cave in the Grand Canyon, where he finds himself "chest deep in sloth dung," to other important fossil sites in Arizona and Chile, Martin's engaging book, written for a wide audience, uncovers our rich evolutionary legacy and shows why he has come to believe that the earliest Americans literally hunted these animals to death.As he discusses the discoveries that brought him to this hypothesis, Martin relates many colorful stories and gives a rich overview of the field of paleontology as well as his own fascinating career. He explores the ramifications of the overkill hypothesis for similar extinctions worldwide and examines other explanations for the extinctions, including climate change. Martin's visionary thinking about our missing megafauna offers inspiration and a challenge for today's conservation efforts as he speculates on what we might do to remedy this situation—both in our thinking about what is "natural" and in the natural world itself.

    In The Story of the Earth in 25 Rocks, Donald R. Prothero tells the fascinating stories behind the discoveries that shook the foundations of geology. In twenty-five chapters—each about a particular rock, outcrop, or geologic phenomenon—Prothero recounts the scientific detective work that took us from the unearthing of exemplary specimens to tectonic shifts in how we view our planet and history.Prothero follows in the footsteps of the scientists who asked—and answered—geology’s biggest questions: How do we know how old the earth is? What happened to the supercontinent Pangea? How did ocean rocks end up at the top of Mount Everest? What can we learn about our planet from meteorites and moon rocks? The Story of the Earth in 25 Rocks answers these questions through expertly chosen case studies, such as Pliny the Elder’s firsthand account of the eruption of Vesuvius; the granite outcrops that led a Scottish scientist to theorize that the landscapes he witnessed were far older than Noah’s Flood; the gypsum deposits under the Mediterranean Sea that indicate that it was once a desert; and how trying to date the age of meteorites revealed the dangers of lead poisoning. Each of these breakthroughs filled in a piece of the puzzle that is the earth, with scientific discoveries dovetailing with each other to offer increasingly solid evidence of the geologic past. Summarizing a wealth of information in an entertaining, approachable style, The Story of the Earth in 25 Rocks is essential reading for the armchair geologist, the rock hound, and all who are curious about the earth beneath their feet.

    They attracted followers ranging from Thomas Jefferson, who laid out mastodon bones on the White House floor, to twentieth-century doctors who used their knowledge of new species to conquer epidemic diseases. Acclaimed science writer Richard Conniff brings these daredevil "species seekers" to vivid life. Alongside their globe-spanning tales of adventure, he recounts some of the most dramatic shifts in the history of human thought. At the start, everyone accepted that the Earth had been created for our benefit. We weren't sure where vegetable ended and animal began, we couldn't classify species, and we didn't understand the causes of disease. But all that changed as the species seekers introduced us to the pantheon of life on Earth—and our place within it.

    We find animals and plants where we do because, over time, the continents have moved, separating and uniting in a long, slow dance; because sea levels have risen, cutting off one bit of land from another; because new and barren volcanic islands have risen up from the sea; and because animals and plants vary greatly in their ability to travel, and separation causes the formation of new species. This is the story of how life has responded to, and has in turn altered, the ever-changing Earth. And it includes many fascinating tales--of pygmy mammoths and elephant birds and of radical ideas by bold young scientists.

    Geological Survey, a lively and revealing history of the world's most disruptive natural disasters, their impact on our culture, and new ways of thinking about the ones to comeNatural disasters emerge from the same forces that give our planet life. Earthquakes have provided us with natural springs. Volcanoes have given us fertile soil. A world without floods would be a world without rain. It is only when these forces exceed our ability to withstand them that they become disasters. Together, these colossal events have shaped our cities and their architecture; elevated leaders and toppled governments; influenced the way we reason, feel, fight, unite, and pray. The history of natural disasters is a history of ourselves.The Big Ones is a look at some of the most devastating disasters in human history, whose reverberations we continue to feel today. It considers Pompeii, and how a volcanic eruption in the first century AD challenged and reinforced prevailing views of religion for centuries to come. It explores the California floods of 1862, examining the failures of our collective memory. And it transports us to today, showing what Hurricane Katrina and the 2004 Indian Ocean tsunami can tell us about governance and globalization. With global temperatures rising, natural disasters are striking with greater frequency. More than just history, The Big Ones is a call to action. Natural disasters are inevitable; human catastrophes are not. With this energizing and richly researched book, Jones offers a look at our past, readying us to face down the Big Ones in our future.

    But how has the earth itself determined our destiny? Our planet wobbles, driving changes in climate that forced the transition from nomadism to farming. Mountainous terrain led to the development of democracy in Greece. Atmospheric circulation patterns later on shaped the progression of global exploration, colonization, and trade. Even today, voting behavior in the south-east United States ultimately follows the underlying pattern of 75 million-year-old sediments from an ancient sea. Everywhere is the deep imprint of the planetary on the human.From the cultivation of the first crops to the founding of modern states, Origins reveals the breathtaking impact of the earth beneath our feet on the shape of our human civilizations.

    It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.

    But to a geologist, stones are richly illustrated narratives, telling gothic tales of cataclysm and reincarnation. For more than four billion years, in beach sand, granite, and garnet schists, the planet has kept a rich and idiosyncratic journal of its past. Fulbright Scholar Marcia Bjornerud takes the reader along on an eye-opening tour of Deep Time, explaining in elegant prose what we see and feel beneath our feet. Both scientist and storyteller, Bjornerud uses anecdotes and metaphors to remind us that our home is a living thing with lessons to teach. She shows how our planet has long maintained a delicate balance, and how the global give-and-take has sustained life on Earth through numerous upheavals. But with the rapidly escalating effects of human beings on their home planet, that cosmic balance is being threatened -- and the consequences may be catastrophic. Containing a glossary and detailed timescale, as well as vivid descriptions and historic accounts, Reading the Rocks is literally a history of the world, for all friends of the Earth.

    Flannery describes the development of North America's deciduous forests and other flora, and tracks the immigration and emigration of various animals to and from Europe, Asia, and South America, showing how plant and animal species have either adapted or become extinct. The story takes in the massive changes wrought by the ice ages and the coming of the Indians, and continues right up to the present, covering the deforestation of the Northeast, the decimation of the buffalo, and other facets of the enormous impact of frontier settlement and the development of the industrial might of the United States. Natural history on a monumental scale, The Eternal Frontier contains an enormous wealth of fascinating scientific details, and Flannery's accessible and dynamic writing makes the book a delight to read. This is science writing at its very best -- a riveting page-turner that is simultaneously an accessible and scholarly trove of incredible information that is already being hailed by critics as a classic. "Tim Flannery's account ... will fascinate Americans and non-Americans alike." -- Jared Diamond, author of Guns, Germs, and Steel "No one before Flannery ... has been brave enough to tackle the whole pageant of North America." -- David Quammen, the New York Times Book Review "Tim Flannery's book will forever change your perspective on the North American continent ... Exhilarating." -- John Terborgh, The New York Review of Books "Full of engaging and attention-catching information about North America's geology, climate, and paleontology." -- Patricia Nelson Limerick, the Washington Post Book World "Natural history par excellence." -- Kirkus Reviews (starred review) "This gutsy Aussie may have read our landscape and ecological history with greater clarity than any native son." -- David A. Burney, Natural History "A fascinating, current, and insightful look at our familiar history from a larger perspective." -- David Bezanson, Austin-American Statesman "The scope of [Flannery's] story is huge, and his research exhaustive." -- Lauren Gravitz, The Christian Science Monitor

    And before there were fish in the sea, there were cephalopods - the ancestors of modern squid and Earth’s first truly substantial animals. Cephalopods became the first creatures to rise from the seafloor, essentially inventing the act of swimming. With dozens of tentacles and formidable shells, they presided over an undersea empire for millions of years. But when fish evolved jaws, the ocean’s former top predator became its most delicious snack. Cephalopods had to step up their game. Many species streamlined their shells and added defensive spines, but these enhancements only provided a brief advantage. Some cephalopods then abandoned the shell entirely, which opened the gates to a flood of evolutionary innovations: masterful camouflage, fin-supplemented jet propulsion, perhaps even dolphin-like intelligence. Squid Empire is an epic adventure spanning hundreds of millions of years, from the marine life of the primordial ocean to the calamari on tonight’s menu. Anyone who enjoys the undersea world—along with all those obsessed with things prehistoric—will be interested in the sometimes enormous, often bizarre creatures that ruled the seas long before the first dinosaurs.

    It hold the remains of an ancient sea where dozens of strange creatures lived—a forgotten corner of evolution preserved in awesome detail. In this book Stephen Jay Gould explores what the Burgess Shale tells us about evolution and the nature of history.

    Scientists around the world are currently monitoring the sixth extinction, predicted to be the most devastating extinction event since the asteroid impact that wiped out the dinosaurs. This time around, the cataclysm is us. In prose that is at once frank, entertaining, and deeply informed, The New Yorker writer Elizabeth Kolbert tells us why and how human beings have altered life on the planet in a way no species has before. Interweaving research in half a dozen disciplines, descriptions of the fascinating species that have already been lost, and the history of extinction as a concept, Kolbert provides a moving and comprehensive account of the disappearances occurring before our very eyes. She shows that the sixth extinction is likely to be mankind's most lasting legacy, compelling us to rethink the fundamental question of what it means to be human.

    How they got here, persevered, and ultimately thrived is a story that resonates from the Pleistocene to our modern era. The lower sea levels of the Ice Age exposed a vast land bridge between Asia and North America, but the land bridge was not the only way across. Different people arrived from different directions, and not all at the same time.The first explorers of the New World were few, their encampments fleeting. The continent they reached had no people but was inhabited by megafauna--mastodons, giant bears, mammoths, saber-toothed cats, five-hundred-pound panthers, enormous bison, and sloths that stood one story tall. The first people were hunters--Paleolithic spear points are still encrusted with the proteins of their prey--but they were wildly outnumbered and many would themselves have been prey to the much larger animals.Atlas of a Lost World chronicles the last millennia of the Ice Age, the violent oscillations and retreat of glaciers, the clues and traces that document the first encounters of early humans, and the animals whose presence governed the humans' chances for survival. A blend of science and personal narrative reveals how much has changed since the time of mammoth hunters, and how little. Across unexplored landscapes yet to be peopled, readers will see the Ice Age, and their own age, in a whole new light.

    Alexander von Humboldt (1769 – 1859) was an intrepid explorer and the most famous scientist of his age. In North America, his name still graces four counties, thirteen towns, a river, parks, bays, lakes, and mountains. His restless life was packed with adventure and discovery, whether he was climbing the highest volcanoes in the world or racing through anthrax-infected Siberia or translating his research into bestselling publications that changed science and thinking. Among Humboldt's most revolutionary ideas was a radical vision of nature, that it is a complex and interconnected global force that does not exist for the use of humankind alone. Now Andrea Wulf brings the man and his achievements back into focus: his daring expeditions and investigation of wild environments around the world and his discoveries of similarities between climate and vegetation zones on different continents. She also discusses his prediction of human-induced climate change, his remarkable ability to fashion poetic narrative out of scientific observation, and his relationships with iconic figures such as Simón Bolívar and Thomas Jefferson. Wulf examines how Humboldt's writings inspired other naturalists and poets such as Darwin, Wordsworth, and Goethe, and she makes the compelling case that it was Humboldt's influence that led John Muir to his ideas of natural preservation and that shaped Thoreau's Walden.With this brilliantly researched and compellingly written book, Andrea Wulf shows the myriad fundamental ways in which Humboldt created our understanding of the natural world, and she champions a renewed interest in this vital and lost player in environmental history and science.

    Europe suffered through a record freeze as the American West was hit with massive floods and snowstorms; in the western Pacific, meanwhile, some island nations literally went bone dry and had to have water flown in on transport planes.Such effects are not new: climatologists now know the El Niño and other climate anomalies have been disrupting weather patterns throughout history. But until recently, no one had asked how this new understanding of the global weather system related to archaeology and history. Droughts, floods, heat and cold put stress on cultures and force them to adapt. What determines whether they adapt successfully? How do these climate stresses affect a people's faith in the foundations of their society and the legitimacy of their rulers? How vulnerable is our own society to climate change?In this dazzlingly original new book, archaeologist Brian Fagan shows that short-term climate shifts have been a major—and hitherto unrecognized—force in history. El Niño-driven droughts have brought on the collapse of dynasties in Egypt; El Niño monsoon failures have caused historic famines in India; and El Niño floods have destroyed whole civilizations in Peru. Other short-term climate changes may have caused the mysterious abandonment of the Anasazi dwellings in the American Southwest and the collapse of the ancient Maya empire, as well as changed the course of European history.This beautifully written, groundbreaking book opens a new door on our understanding of historical events.
