    But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come.

    Melting glaciers, warming oceans, droughts-it's clear that today's world is getting hotter. But while we know the agony of a sunburn or the comfort of our winter heaters, do we really understand heat? A bestselling scientist and nature writer who goes to any extreme to uncover the answers, Bill Streever sets off to find out what heat really means. Let him be your guide and you'll firewalk across hot coals and sweat it out in Death Valley, experience intense fever and fire, learn about the invention of matches and the chemistry of cooking, drink crude oil, and explore thermonuclear weapons and the hottest moment of all time-the big bang. Written in Streever's signature spare and refreshing prose, Heat is an adventurous personal narrative that leaves readers with a new vision of an everyday experience-how heat works, its history, and its relationship to daily life.

    In what began as groundbreaking three-part series in the New Yorker, for which she won a National Magazine Award in 2006, Kolbert cuts through the competing rhetoric and political agendas to elucidate for Americans what is really going on with the global environment and asks what, if anything, can be done to save our planet. Now updated and with a new afterword, Field Notes from a Catastrophe is the book to read on the defining issue and greatest challenge of our times.

    Here are astounding animals of every stripe: Dung beetles that steer by the light of the Milky Way. Ants and bees that rely on patterns of light invisible to humans. Sea turtles and moths that find their way using Earth’s magnetic field. Humpback whales that swim thousands of miles while holding a rocksteady course. Birds that can locate their nests on a tiny island after crisscrossing an ocean.The age of viewing animals as unthinking drones is over. As Supernavigators makes clear, a stunning array of species command senses and skills—and arguably, types of intelligence—beyond our own. Weaving together interviews with leading animal behaviorists and the groundbreaking discoveries of Nobel Prize–winning scientists, David Barrie reveals these wonders in a whole new light.

    It was to last five years and transform him from an amiable and somewhat aimless young man into a scientific celebrity. Even more vitally, it was to set in motion the intellectual currents that culminated in the arrival of The Origin of Species in Victorian drawing-rooms in 1859. His journal, reprinted here in a shortened version, is vivid and immediate, showing us a naturalist making patient observations, above all in geology. As well as a profusion of natural history detail, it records many other things that caught Darwin’s eye, from civil war in Argentina to the new colonial settlements of Australia. The editors have provided an excellent introduction and notes for this Penguin Classics edition, which also contains maps and appendices, including an essay on scientific geology and the Bible by Robert FitzRoy, Darwin’s friend and captain of the Beagle.

    Legendary geologist J Harlen Bretz was the first to explore the area, starting in the 1920s. This dramatic book tells the story of this scientific maverick — how he came to study the region, his radical theory that a flood of biblical proportions created it, and how a campaign by the mainstream geologic community tried to derail him for pursuing an idea that satellite photos would confirm decades later.

    The passage of nine days, which is how long a drop of water typically stays in Earth's atmosphere, is something we can easily grasp. But spans of hundreds of years--the time a molecule of carbon dioxide resides in the atmosphere--approach the limits of our comprehension. Our everyday lives are shaped by processes that vastly predate us, and our habits will in turn have consequences that will outlast us by generations. Timefulness reveals how knowing the rhythms of Earth's deep past and conceiving of time as a geologist does can give us the perspective we need for a more sustainable future.Marcia Bjornerud shows how geologists chart the planet's past, explaining how we can determine the pace of solid Earth processes such as mountain building and erosion and comparing them with the more unstable rhythms of the oceans and atmosphere. These overlapping rates of change in the Earth system--some fast, some slow--demand a poly-temporal worldview, one that Bjornerud calls "timefulness." She explains why timefulness is vital in the Anthropocene, this human epoch of accelerating planetary change, and proposes sensible solutions for building a more time-literate society.This compelling book presents a new way of thinking about our place in time, enabling us to make decisions on multigenerational timescales. The lifespan of Earth may seem unfathomable compared to the brevity of human existence, but this view of time denies our deep roots in Earth's history--and the magnitude of our effects on the planet.

    Deliberately hiding from the outside world, they are the unconquered, the last survivors of an ancient culture that predates the arrival of Columbus in the New World.  In this gripping first-person account of adventure and survival, author Scott Wallace chronicles an expedition into the Amazon’s uncharted depths, discovering the rainforest’s secrets while moving ever closer to a possible encounter with one such tribe—the mysterious flecheiros, or “People of the Arrow,” seldom-glimpsed warriors known to repulse all intruders with showers of deadly arrows. On assignment for National Geographic, Wallace joins Brazilian explorer Sydney Possuelo at the head of a thirty-four-man team that ventures deep into the unknown in search of the tribe. Possuelo’s mission is to protect the Arrow People. But the information he needs to do so can only be gleaned by entering a world of permanent twilight beneath the forest canopy.Danger lurks at every step as the expedition seeks out the Arrow People even while trying to avoid them. Along the way, Wallace uncovers clues as to who the Arrow People might be, how they have managed to endure as one of the last unconquered tribes, and why so much about them must remain shrouded in mystery if they are to survive. Laced with lessons from anthropology and the Amazon’s own convulsed history, and boasting a Conradian cast of unforgettable characters—all driven by a passion to preserve the wild, but also wracked by fear, suspicion, and the desperate need to make it home alive—The Unconquered reveals this critical battleground in the fight to save the planet as it has rarely been seen, wrapped in a page-turning tale of adventure.

    Passed through, negotiated, unnamed, ignored, the edgelands have become the great wild places on our doorsteps, places so difficult to acknowledge they barely exist. Edgelands forms a critique of what we value as 'wild', and allows our allotments, railways, motorways, wasteland and water a presence in the world, and a strange beauty all of their own.Paul Farley and Michael Symmons Roberts - both well-known poets - have lived and worked and known these places all their lives, and in Edgelands their journeying prose fuses, in the anonymous tradition, to allow this in-between world to speak up for itself. They write about mobile masts and gravel pits, business parks and landfill sites in the same way the Romantic writers forged a way of looking at an overlooked - but now familiar - landscape of hills and lakes and rivers. England, the first country to industrialise, now offers the world's most mature post-industrial terrain, and is still in a state of flux: Edgelands takes the reader on a journey through its forgotten spaces so that we can marvel at this richly mysterious, cheek-by-jowl region in our midst.

    From the thawing tundra linking a Yup'ik village in Alaska to its hunter-gatherer past to the shifting sand dunes revealing the impressively preserved homes of neolithic farmers in Scotland, Jamie explores how the changing natural world can alter our sense of time. Most movingly, she considers, as her father dies and her children leave home, the surfacing of an older, less tethered sense of herself. In precise, luminous prose, Surfacing offers a profound sense of time passing and an antidote to all that is instant, ephemeral, unrooted.

    And so, in this rich and original work that explores the Gulf through our human connection with the sea, environmental historian Jack E. Davis finally places this exceptional region into the American mythos in a sweeping history that extends from the Pleistocene age to the twenty-first century.Significant beyond tragic oil spills and hurricanes, the Gulf has historically been one of the world's most bounteous marine environments, supporting human life for millennia. Davis starts from the premise that nature lies at the center of human existence, and takes readers on a compelling and, at times, wrenching journey from the Florida Keys to the Texas Rio Grande, along marshy shorelines and majestic estuarine bays, profoundly beautiful and life-giving, though fated to exploitation by esurient oil men and real-estate developers.Rich in vivid, previously untold stories, The Gulf tells the larger narrative of the American Sea—from the sportfish that brought the earliest tourists to Gulf shores to Hollywood’s engagement with the first offshore oil wells—as it inspired and empowered, sometimes to its own detriment, the ethnically diverse groups of a growing nation. Davis' pageant of historical characters is vast, including: the presidents who directed western expansion toward its shores, the New England fishers who introduced their own distinct skills to the region, and the industries and big agriculture that sent their contamination downstream into the estuarine wonderland. Nor does Davis neglect the colorfully idiosyncratic individuals: the Tabasco king who devoted his life to wildlife conservation, the Texas shrimper who gave hers to clean water and public health, as well as the New York architect who hooked the “big one” that set the sportfishing world on fire.Ultimately, Davis reminds us that amidst the ruin, beauty awaits its return, as the Gulf is, and has always been, an ongoing story. Sensitive to the imminent effects of climate change, and to the difficult task of rectifying grievous assaults of recent centuries, The Gulf suggests how a penetrating examination of a single region's history can inform the country's path ahead.

    It is part journey, part history, and it concludes with awkward questions about the future of Britain's landscapes. Nick Crane's story begins with the melting tongues of glaciers and the emergence of a gigantic game-park tentatively being explored by a vanguard of Mesolithic adventurers who have taken the long, northward hike across the land bridge from the continent. The Iron Age develops into a pre-Roman 'Golden Era' and Nick Crane looks at what the Romans did (and didn't) contribute to the British landscape. Major landscape 'events' (Black Death, enclosures, urbanisation, recreation, etc.) are fully described and explored, and he weaves in the role played by geology in shaping our cities, industry and recreation, the effect of climate (and the Gulf Stream), and of global economics (the Lancashire valleys were formed by overseas markets). The co-presenter of BBC's Coast also covers the extraordinary benefits bestowed by a 6,000-mile coastline. The 10,000-year story of the British landscape culminates in the 21st century, which is set to be one of the most extreme centuries of change since the Ice Age.Nick Crane brilliantly illustrates how Britain and its landscapes became so wonderfully diverse.

    Gorongosa National Park in Mozambique was nearly destroyed in a brutal civil war, then was reborn and is now evolving back to its original state. Edward O. Wilson’s personal, luminous description of the wonders of Gorongosa is beautifully complemented by Piotr Naskrecki’s extraordinary photographs of the park’s exquisite natural beauty. A bonus DVD of Academy Award–winning director Jessica Yu’s documentary, The Guide, is also included with the book.Wilson takes readers to the summit of Mount Gorongosa, sacred to the local people and the park’s vital watershed. From the forests of the mountain he brings us to the deep gorges on the edge of the Rift Valley, previously unexplored by biologists, to search for new species and assess their ancient origins. He describes amazing animal encounters from huge colonies of agricultural termites to spe­cialized raider ants that feed on them to giant spi­ders, a battle between an eagle and a black mamba, “conversations” with traumatized elephants that survived the slaughter of the park’s large animals, and more. He pleads for Gorongosa—and other wild places—to be allowed to exist and evolve in its time­less way uninterrupted into the future.As he examines the near destruction and rebirth of Gorongosa, Wilson analyzes the balance of nature, which, he observes, teeters on a razor’s edge. Loss of even a single species can have serious ramifications throughout an ecosystem, and yet we are carelessly destroying complex biodiverse ecosystems with unknown consequences. The wildlands in which these ecosystems flourish gave birth to humanity, and it is this natural world, still evolving, that may outlast us and become our leg­acy, our window on eternity.
