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.

    Building on research that has only recently confirmed that the world endured a 500year cold snap, renowned archaeologist Brian Fagan shows how the increasing cold influenced familiar events from Norse exploration to the settlement of North America to the Industrial Revolution. This is a fascinating book for anyone interested in history, climate, and how they interact.

    The lens he invented was a brilliant feat of engineering that made lighthouses blaze many times brighter, farther, and more efficiently. Battling the establishment, his own poor health, and the limited technology of the time, Fresnel was able to achieve his goal of illuminating the entire French coast. At first, the British sought to outdo the new Fresnel-equipped lighthouses as a matter of national pride. Americans, too, resisted abandoning their primitive lamps, but the superiority of the Fresnel lens could not be denied for long. Soon, from Dunkirk to Saigon, shores were brightened with it.  The Fresnel legacy played an important role in geopolitical events, including the American Civil War. No sooner were Fresnel lenses finally installed along U.S. shores than they were drafted: the Union blockaded the Confederate coast; the Confederacy set about thwarting it by dismantling and hiding or destroying the powerful new lights.Levitt’s scientific and historical account, rich in anecdote and personality, brings to life the fascinating untold story of Augustin Fresnel and his powerful invention.

    When he emerged three years later, the summation of his efforts only hinted at what he'd experienced in one of the most dangerous regions on earth. Armed with an astonishing collection of zoological specimens, Du Chaillu leapt from the physical challenges of the jungle straight into the center of the biggest issues of the time--the evolution debate, racial discourse, the growth of Christian fundamentalism--and helped push each to unprecedented intensities. He experienced instant celebrity, but with that fame came whispers--about his past, his credibility, and his very identity--which would haunt the young man. Grand in scope, immediate in detail, and propulsively readable, Between Man and Beast brilliantly combines Du Chaillu's personal journey with the epic tale of a world hovering on the sharp edge of transformation.

    The thrill-seeking meteorologist and star of "Storm Chasers" has followed and faced down more violent tornadoes than anyone. "Into the Storm" brings readers into the mind of this man and his mission-collecting data that could save lives-in the terrifying, awe-inspiring world of big weather."Into the Storm" is also a fascinating look at the science of weather-what causes extreme conditions, its connection to climate change, and how a tornado gets its stovepipe structure.

    With winds estimated at over 225 miles per hour, it was the first recorded Category 5 hurricane to make landfall in the United States.Striking at a time before storms were named, the catastrophic tropical cyclone became known as the 1935 Labor Day Hurricane, and its aftermath was felt all the way to Washington, D.C. In the hardest hit area of the Florida Keys, three out of every five residents were killed, while hundreds of World War I veterans sent there by the federal government perished.By sifting through overlooked official records and interviewing survivors and the relatives of victims, Thomas Knowles pieces together this dramatic story, moment by horrifying moment. He explains what daily life was like on the Keys, why the veteran work force was there (and relatively unprotected), the state of weather forecasting at the time, the activities of the media covering the disaster, and the actions of government agencies in the face of severe criticism over their response to the disaster.The Labor Day Hurricane of 1935 remains one of the most intense to strike America's shores. Category 5 is a sobering reminder that even with modern meteorological tools and emergency management systems, a similar storm could cause even more death and destruction today.

    Shows how our concept of humankind has changed over time and argues our current understanding of what it means to be human has been shaken by new discoveries from science and philosophy.

    Considering the physiology and motivation of running from a scientific point of view, he wondered what he could learn from other animals.In Why We Run, Heinrich considers the flight endurance of birds, the antelope’s running prowess and limitations, and the ultra-endurance of camels to understand how human physiology can or cannot replicate these adaptations. With his characteristic blend of scientific inquiry and philosophical musings, Heinrich offers an original and provocative work combining the rigors of science with the passion of running.

    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.

    In The Ends of the World, Peter Brannen dives into deep time, exploring Earth’s past dead ends, and in the process, offers us a glimpse of our possible future.Many scientists now believe that the climate shifts of the twenty-first century have analogs in these five extinctions. Using the visible clues these devastations have left behind in the fossil record, The Ends of the World takes us inside “scenes of the crime,” from South Africa to the New York Palisades, to tell the story of each extinction. Brannen examines the fossil record—which is rife with creatures like dragonflies the size of sea gulls and guillotine-mouthed fish—and introduces us to the researchers on the front lines who, using the forensic tools of modern science, are piecing together what really happened at the crime scenes of the Earth’s biggest whodunits.Part road trip, part history, and part cautionary tale, The Ends of the World takes us on a tour of the ways that our planet has clawed itself back from the grave, and casts our future in a completely new light.

    

     Climate has been humanity's constant, if moody, companion. At times benefactor or tormentor, climate nurtured the first stirrings of civilization and then repeatedly visited ruin on empires and peoples. Eugene Linden reveals a recurring pattern in which civilizations become prosperous and complacent during good weather, only to collapse when climate changes -- either through its direct effects, such as floods or drought, or indirect consequences, such as disease, blight, and civil disorder. The science of climate change is still young, and the interactions of climate with other historical forces are much debated, but the evidence mounts that climate loomed over the fate of societies from arctic Greenland to the Fertile Crescent and from the lost cities of the Mayans in Central America to the rain forests of Central Africa. Taking into account the uncertainties in both science and the historical record, Linden explores the evidence indicating that climate has been a serial killer of civilizations. The Winds of Change looks at the present and then to the future to determine whether the accused killer is on the prowl, and what it will do in the future. The tragedy of New Orleans is but the latest instance in which a region prepared for weather disasters experienced in the past finds itself helpless when nature ups the ante. In the closing chapters, Linden explores why warnings about the dangers of climate change have gone unheeded and what is happening with climate today, and he offers perhaps the most explicit look yet at what a haywire climate might do to us. He shows how even a society prepared to absorb such threshold-crossing events as Katrina, the killer heat wave in Europe in 2003, or the floods in the American Midwest in the 1990s can spiral into precipitous decline should such events intensify and become more frequent. The Winds of Change places climate change, global warming, and the resulting instability in historical context and sounds an urgent warning for the future.

     From 1799 to 1804 German naturalist and adventurer Alexander von Humboldt conducted the first extensive scientific exploration of Latin America. At the completion of his arduous 6,000-mile journey, he was feted by Thomas Jefferson and presented to Napoleon, and, with the subsequent publication of his findings, he would be hailed as the greatest scientific genius of his age. Humboldt’s Cosmos tells the story of this extraordinary man who was equal parts Einstein and Livingstone, and of the adventure that defined his life. Gerard Helferich vividly recounts Humboldt’s expedition through the Amazon and over the Andes, highlighting his paradigm-changing discoveries along the way. During the course of the expedition, Humboldt cataloged more than 60,000 plants, set an altitude record climbing the volcano Chimborazo, and became the first to study the great cultures of the Aztecs and Incas. In the process, he revolutionized geology and laid the groundwork for modern sciences such as climatology, oceanography, and geography—and his contributions would influence future greats such as Charles Darwin and shape the course of science for centuries to come. Published in time for the bicentennial of the expedition’s completion in May 1804, Humboldt’s Cosmos is a dramatic tribute to one of history’s most audacious adventurers, whom Stephen Jay Gould noted “may well have been the world’s most famous and influential intellectual.”

    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.
