Prized as “the best stone in Britain” by Roman invaders who carved jewelry out of it, coal has transformed societies, expanded frontiers, and sparked social movements, and still powers our electric grid. Yet coal’s world-changing power has come at a tremendous price, including centuries of blackening our skies and lungs—and now the dangerous warming of our global climate. Ranging from the “great stinking fogs” of London to the rat-infested coal mines of Pennsylvania, from the impoverished slums of Manchester to the toxic streets of Beijing, Coal is a captivating narrative about an ordinary substance with an extraordinary impact on human civilization.

    They are found on the Moon, where fifty-six miles of car tracks lie nearly perfectly preserved, etched into the lunar landscape almost exactly as they were left nearly a half-century ago. The ends of these trails mark the farthest extremes to which mankind has ventured, the limits of a species that was born to wander.The tracks were left by crews of the last three manned missions to the Moon—Apollos 15, 16, and 17. Over the decades since, the achievements of these astronauts have dimmed in the shadow cast by the first Moon landing, Apollo 11. But as Earl Swift brilliantly uncovers, in so many ways the earlier missions were but a prelude for the final acts; for while Neil Armstrong and Buzz Aldrin trod a chunk of flat lunar plain smaller than a football field, the final three Apollos each commanded a mountainous area the size of Manhattan—traveling miles across the broken, desolate lunar surface, conducting experiments, and collecting more than a quarter-ton of prized geologic samples. Often treated as little more than historical footnotes, they were the true explorers of the Moon. And they succeeded for one very American reason: they drove.So-called “Moon cars” had been the stuff of science fiction since before the Wright brothers flew. But it was only after World War II that engineers and scientists took up the challenge of how to move astronauts and equipment across extraterrestrial landscapes. The result was the Lunar Roving Vehicle—a true engineering marvel that was developed piecemeal through the late 1950s and 1960s, deployed on the final three Apollo missions, and revolutionized the exploration of the moon.In this fast-moving exploration of the lunar rover and the scientific discoveries it enabled, Swift puts the reader alongside the men who dreamed of the rover, designed it, troubleshot its flaws, and drove it on the lunar surface. Finally shining a deserved spotlight on these overlooked yet crucial missions and the fascinating characters involved in them, Across the Airless Wilds is a celebration of human genius, perseverance, and daring.

    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.

    After World War II, it reshaped the global order-whoever could master uranium could master the world. Marie Curie gave us hope that uranium would be a miracle panacea, but the Manhattan Project gave us reason to believe that civilization would end with apocalypse. Slave labor camps in Africa and Eastern Europe were built around mine shafts and America would knowingly send more than six hundred uranium miners to their graves in the name of national security. Fortunes have been made from this yellow dirt; massive energy grids have been run from it. Fear of it panicked the American people into supporting a questionable war with Iraq and its specter threatens to create another conflict in Iran. Now, some are hoping it can help avoid a global warming catastrophe. In "Uranium," Tom Zoellner takes readers around the globe in this intriguing look at the mineral that can sustain life or destroy it.

    Whether or not we take heed, these urgent crises of industrial agriculture will define our future.In Perilous Bounty, veteran journalist and former farmer Tom Philpott explores and exposes the small handful of seed and pesticide corporations, investment funds, and magnates who benefit from the trends that imperil us, with on-the-ground dispatches featuring the scientists documenting the damage and the farmers and activists who are valiantly and inventively pushing back. Resource scarcity looms on the horizon, but rather than pointing us toward an inevitable doomsday, Philpott shows how the entire wayward ship of American agriculture could be routed away from its path to disaster. He profiles the farmers and communities in the nation's two key growing regions developing resilient, soil-building, water-smart farming practices, and readying for the climate shocks that are already upon us; and he explains how we can help move these methods from the margins to the mainstream.

    Generating cataclysmic volcanic eruptions and large earthquakes, the hotspot helped lift the Yellowstone Plateau to more than 7,000 feet and pushed the northern Rockies to new heights, forming unusually large glaciers to carve the landscape. It also created the jewel of the U.S. national park system: Yellowstone. Meanwhile, forces stretching apart the western U.S. created the mountainous glory of Grand Teton National Park. These two parks, with their majestic mountains, dazzling geysers, and picturesque hot springs, are windows into the Earth's interior, revealing the violent power of the dynamic processes within. Smith and Siegel offer expert guidance through this awe-inspiring terrain, bringing to life the grandeur of these geologic phenomena as they reveal the forces that have shaped--and continue to shape--the greater Yellowstone-Teton region. Over seventy illustrations--including fifty-two in full color--illuminate the breathtaking beauty of the landscape, while two final chapters provide driving tours of the parks to help visitors enjoy and understand the regions wonders. Fascinating and informative, this book affords us a striking new perspective on Earth's creative forces.

    But most people who lived during the 10,000 years before the nineteenth century thought just the opposite. Drawing on archaeology, anthropology, biology, and history, Ian Morris explains why. Fundamental long-term changes in values, Morris argues, are driven by the most basic force of all: energy. Humans have found three main ways to get the energy they need--from foraging, farming, and fossil fuels. Each energy source sets strict limits on what kinds of societies can succeed, and each kind of society rewards specific values. But if our fossil-fuel world favors democratic, open societies, the ongoing revolution in energy capture means that our most cherished values are very likely to turn out not to be useful any more. Foragers, Farmers, and Fossil Fuels offers a compelling new argument about the evolution of human values, one that has far-reaching implications for how we understand the past--and for what might happen next. Originating as the Tanner Lectures delivered at Princeton University, the book includes challenging responses by classicist Richard Seaford, historian of China Jonathan Spence, philosopher Christine Korsgaard, and novelist Margaret Atwood.

    In this disturbing new book, Lovelock guides us toward a hard reality: soon, we may not be able to alter the oncoming climate crisis. Lovelock’s influential Gaia theory, one of the building blocks of modern climate science, conceives of the Earth, including the atmosphere, oceans, biosphere and upper layers of rock, as a single living super-organism, regulating its internal environment much as an animal regulates its body temperature and chemical balance. But now, says Lovelock, that organism is sick. It is running a fever born of the combination of a sun whose intensity is slowly growing over millions of years, and an atmosphere whose greenhouse gases have recently spiked due to human activity. Earth will adjust to these stresses, but on time scales measured in the hundreds of millennia. It is already too late, Lovelock says, to prevent the global climate from “flipping” into an entirely new equilibrium state that will leave the tropics uninhabitable, and force migration to the poles. The Revenge of Gaia explains the stress the planetary system is under and how humans are contributing to it, what the consequences will be, and what humanity must do to rescue itself.

    Lured by the promise of riches, thousands of settlers left behind the forests, rain, and fertile soil of the eastern United States in favor of the rough-hewn lands of the American West. The dramatic terrain they struggled to cross is so familiar to us now that it is hard to imagine how frightening—even godforsaken—its sheer rock faces and barren deserts seemed to our forebears.        Hard Road West brings their perspective vividly to life, weaving together the epic overland journey of the covered wagon trains and the compelling story of the landscape they encountered. Taking readers along the 2,000-mile California Trail, Keith Meldahl uses the diaries and letters of the settlers themselves—as well as the countless hours he has spent following the trail—to reveal how the geology and geography of the West directly affected our nation’s westward expansion. He guides us through a corrugated landscape of sawtooth mountains, following the meager streams that served as lifelines through an arid land, all the way to California itself, where colliding tectonic plates created breathtaking scenery and planted the gold that lured travelers west in the first place. “Alternates seamlessly between vivid accounts of the 19th-century journey and lucid explanations of the geological events that shaped the landscape traveled. . . . The reader comes away with both an appreciation for the arduous cross-continental wagon journey and an understanding of the events that created such a vast and difficult landscape.”—Library Journal “[Meldahl] draws on his professional knowledge to explain the geology of the West, showing how centuries of geological activity had a direct effect on the routes taken by the travelers. . . . Meldahl provides a novel account of the largest overland migration since the Crusades.”—Science News

    He shows how a forensic approach to volcanology reveals the richness and complexity behind cause and effect, and argues that important lessons for future catastrophe risk management can be drawn from understanding events that took place even at the dawn of human origins.

    In America, energy consumed by home air-conditioning, and the resulting greenhouse emissions, have doubled in just over a decade, and energy to cool retail stores has risen by two-thirds. Now the entire affluent world is adopting the technology. As the biggest economic crisis in eighty years rolls across the globe, financial concerns threaten to shove ecological crises into the background. Reporting from some of the world’s hot zones—from Phoenix, Arizona, and Naples, Florida, to southern India—Cox documents the surprising ways in which air-conditioning changes human experience: giving a boost to the global warming that it is designed to help us endure, providing a potent commercial stimulant, making possible an impossible commuter economy, and altering migration patterns (air-conditioning has helped alter the political hue of the United States by enabling a population boom in the red-state Sun Belt).While the book proves that the planet’s atmosphere cannot sustain even our current use of air-conditioning, it also makes a much more positive argument that loosening our attachment to refrigerated air could bring benefits to humans and the planet that go well beyond averting a climate crisis. Though it saves lives in heat waves, air-conditioning may also be altering our bodies’ sensitivity to heat; our rates of infection, allergy, asthma, and obesity; and even our sex drive. Air-conditioning has eroded social bonds and thwarted childhood adventure; it has transformed the ways we eat, sleep, travel, work, buy, relax, vote, and make both love and war. The final chapter surveys the many alternatives to conventional central air-conditioning. By reintroducing some traditional cooling methods, putting newly emerging technologies into practice, and getting beyond industrial definitions of comfort, we can make ourselves comfortable and keep the planet comfortable, too.
