At present, Lake Powell is less than half full. Bathtub rings ten stories tall encircle its blue water; boat ramps and marinas lie stranded and useless. To refill it would require surplus water—but there is no surplus: burgeoning populations and thirsty crops consume every drop of the Colorado River. Add to this picture the looming effects of global warming and drought, and the scenario becomes bleaker still. Dead Pool, featuring rarely seen historical photographs, explains why America built the dam that made Lake Powell and others like it and then allowed its citizens to become dependent on their benefits, which were always temporary. Writing for a wide audience, Powell shows us exactly why an urgent threat during the first half of the twenty-first century will come not from the rising of the seas but from the falling of the reservoirs.

    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.

    It didn’t stop anywhere in north Europe until August. Next came the four coldest winters in a millennium. Two separate animal epidemics killed nearly 80 percent of northern Europe’s livestock. Wars between Scotland and England, France and Flanders, and two rival claimants to the Holy Roman Empire destroyed all remaining farmland. After seven years, the combination of lost harvests, warfare, and pestilence would claim six million lives—one eighth of Europe’s total population. William Rosen draws on a wide array of disciplines, from military history to feudal law to agricultural economics and climatology, to trace the succession of traumas that caused the Great Famine. With dramatic appearances by Scotland’s William Wallace, and the luckless Edward II and his treacherous Queen Isabella, history’s best documented episode of catastrophic climate change comes alive, with powerful implications for future calamities.

    He wrote vast volumes about animals. He described them, classified them, told us where and how they live and how they develop in the womb or in the egg. He founded a science. It can even be said that he founded science itself.In The Lagoon, acclaimed biologist Armand Marie Leroi recovers Aristotle’s science. He revisits Aristotle’s writings and the places where he worked. He goes to the eastern Aegean island of Lesbos to see the creatures that Aristotle saw, where he saw them. He explores Aristotle’s observations, his deep ideas, his inspired guesses—and the things he got wildly wrong. He shows how Aristotle’s science is deeply intertwined with his philosophical system and reveals that he was not only the first biologist, but also one of the greatest.The Lagoon is both a travelogue and a study of the origins of science. And it shows how a philosopher who lived almost two millennia ago still has so much to teach us today.

    James Hansen—the nation’s leading scientist on climate issues—speaks out for the first time with the full truth about global warming: The planet is hurtling even more rapidly than previously acknowledged to a climatic point of no return.Although the threat of human-caused climate change is now widely recognized, politicians have failed to connect policy with the science, responding instead with ineffectual remedies dictated by special interests. Hansen shows why President Obama’s solution, cap-and-trade, which Al Gore has signed on to, won’t work; why we must phase out all coal; and why 350 parts per million of carbon dioxide in the atmosphere is a goal we must achieve if our children and grandchildren are to avoid global meltdown and the horrific storms of the book’s title. This urgent manifesto bucks conventional wisdom (including the Kyoto Protocol) and is sure to stir controversy, but Hansen—whose climate predictions have come to pass again and again, beginning in the 1980s when he first warned Congress about global warming—is the single most credible voice on the subject worldwide.Hansen paints a devastating, all-too-realistic picture of what will happen in the near future, mere years and decades from now, if we follow the course we’re on. But he is also an optimist, showing that there is still time to do what we need to save the planet. Urgent, strong action is needed, and this book will be key in setting the agenda going forward to create a groundswell, a tipping point, to save humanity—and our grandchildren—from a dire fate more imminent than we had supposed.

    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.

    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.

    1816 was a remarkable year—mostly for the fact that there was no summer. As a result of a volcanic eruption in Indonesia, weather patterns were disrupted worldwide for months, allowing for excessive rain, frost, and snowfall through much of the Northeastern U.S. and Europe in the summer of 1816.In the U.S., the extraordinary weather produced food shortages, religious revivals, and extensive migration from New England to the Midwest. In Europe, the cold and wet summer led to famine, food riots, the transformation of stable communities into wandering beggars, and one of the worst typhus epidemics in history. 1816 was the year Frankenstein was written. It was also the year Turner painted his fiery sunsets. All of these things are linked to global climate change—something we are quite aware of now, but that was utterly mysterious to people in the nineteenth century, who concocted all sorts of reasons for such an ungenial season.Making use of a wealth of source material and employing a compelling narrative approach featuring peasants and royalty, politicians, writers, and scientists, The Year Without Summer by William K. Klingaman and Nicholas P. Klingaman examines not only the climate change engendered by this event, but also its effects on politics, the economy, the arts, and social structures.

    After the Ice is the story of this momentous period--one in which a seemingly minor alteration in temperature could presage anything from the spread of lush woodland to the coming of apocalyptic floods--and one in which we find the origins of civilization itself.Drawing on the latest research in archaeology, human genetics, and environmental science, After the Ice takes the reader on a sweeping tour of 15,000 years of human history. Steven Mithen brings this world to life through the eyes of an imaginary modern traveler--John Lubbock, namesake of the great Victorian polymath and author of Prehistoric Times. With Lubbock, readers visit and observe communities and landscapes, experiencing prehistoric life--from aboriginal hunting parties in Tasmania, to the corralling of wild sheep in the central Sahara, to the efforts of the Guila Naquitz people in Oaxaca to combat drought with agricultural innovations.Part history, part science, part time travel, After the Ice offers an evocative and uniquely compelling portrayal of diverse cultures, lives, and landscapes that laid the foundations of the modern world.

    But they are relative newcomers there. They evolved in North America and retain their greatest diversity in South America, while the only wild dromedaries are in Australia.This is a classic example of the contradictions of 'native' and 'invasive' species, a hot issue right now as the flip-side of biodiversity. Do we need to fear invaders? Can we control them? Do we choose the right targets? And are the natives always good guys?Thompson puts forward a fascinating array of narratives to explore this crucial question.

    It's weirder than we are capable of imagining. And we're all in it together: humans, blue whales, rats, birds of paradise, ridiculous numbers of beetles, molluscs the size of a bus, the sexual gladiators of slugs, bdelliod rotifers who haven't had sex for millions of years and creatures called water bears: you can boil them, freeze them and fire them off into space without killing themWe're all part of the animal kingdom, appearing in what Darwin called 'endless forms most beautiful and most wonderful'. In this breathtakingly audacious book Simon Barnes has brought us all together, seeking not what separates us but what unites us. He takes us white-water rafting through the entire animal kingdom in a book that brings in deep layers of arcane knowledge, the works of Darwin and James Joyce, Barnes's own don't-try-this-at-home adventures in the wild, David Attenborough and Sherlock Holmes.

    But such is Stephen Jay Gould's command of paleontology and evolutionary theory, and his gift for brilliant explication, that he has brought dust and dead bones to life, and developed an immense following for the seeming arcana of this field.In Time's Arrow, Time's Cycle his subject is nothing less than geology's signal contribution to human thought--the discovery of "deep time," the vastness of earth's history, a history so ancient that we can comprehend it only as metaphor. He follows a single thread through three documents that mark the transition in our thinking from thousands to billions of years: Thomas Burnet's four-volume Sacred Theory of the Earth (1680-1690), James Hutton's Theory of the Earth (1795), and Charles Lyell's three-volume Principles of Geology (1830-1833).Gould's major theme is the role of metaphor in the formulation and testing of scientific theories--in this case the insight provided by the oldest traditional dichotomy of Judeo-Christian thought: the directionality of time's arrow or the immanence of time's cycle. Gould follows these metaphors through these three great documents and shows how their influence, more than the empirical observation of rocks in the field, provoked the supposed discovery of deep time by Hutton and Lyell. Gould breaks through the traditional "cardboard" history of geological textbooks (the progressive march to truth inspired by more and better observations) by showing that Burnet, the villain of conventional accounts, was a rationalist (not a theologically driven miracle-monger) whose rich reconstruction of earth history emphasized the need for both time's arrow (narrative history) and time's cycle (immanent laws), while Hutton and Lyell, our traditional heroes, denied the richness of history by their exclusive focus upon time's Arrow.

    In the 1990s he and his colleagues made headlines with the discovery that the last ice age came to an abrupt end over a period of only three years. Here Alley offers the first popular account of the wildly fluctuating climate that characterized most of prehistory--long deep freezes alternating briefly with mild conditions--and explains that we humans have experienced an unusually temperate climate. But, he warns, our comfortable environment could come to an end in a matter of years."The Two-Mile Time Machine" begins with the story behind the extensive research in Greenland in the early 1990s, when scientists were beginning to discover ancient ice as an archive of critical information about the climate. Drilling down two miles into the ice, they found atmospheric chemicals and dust that enabled them to construct a record of such phenomena as wind patterns and precipitation over the past 110,000 years. The record suggests that "switches" as well as "dials" control the earth's climate, affecting, for example, hot ocean currents that today enable roses to grow in Europe farther north than polar bears grow in Canada. Throughout most of history, these currents switched on and off repeatedly (due partly to collapsing ice sheets), throwing much of the world from hot to icy and back again in as little as a few years.Alley explains the discovery process in terms the general reader can understand, while laying out the issues that require further study: What are the mechanisms that turn these dials and flip these switches? Is the earth due for another drastic change, one that will reconfigure coastlines or send certain regions into severe drought? Will global warming combine with natural variations in Earth's orbit to flip the North Atlantic switch again? Predicting the long-term climate is one of the greatest challenges facing scientists in the twenty-first century, and Alley tells us what we need to know in order to understand and perhaps overcome climate changes in the future.

    Edward O. Wilson eloquently describes how the species of the world became diverse and why that diversity is threatened today as never before. A great spasm of extinction — the disappearance of whole species — is occurring now, caused this time entirely by humans. Unlike the deterioration of the physical environment, which can be halted, the loss of biodiversity is a far more complex problem — and it is irreversible. Defining a new environmental ethic, Wilson explains why we must rescue whole ecosystems, not only individual species. He calls for an end to conservation versus development arguments, and he outlines the massive shift in priorities needed to address this challenge. No writer, no scientist, is more qualified than Edward O. Wilson to describe, as he does here, the grandeur of evolution and what is at stake. "Engaging and nontechnical prose. . . .

A profound and enduring contribution." — Alan Burdick, Audubon

    Traveling through the dizzying expanse of geologic time—from prehistoric art in Norwegian sea caves, to the blue depths of the Greenland ice cap, to a deep-sunk "hiding place" where nuclear waste will be stored for 100,000 years to come—Underland takes us on an extraordinary journey into our relationship with darkness, burial, and what lies beneath the surface of both place and mind.Global in its geography and written with great lyricism, Underland speaks powerfully to our present moment. At once ancient and urgent, this is a book that will change the way you see the world.
