    Earth, born in a nuclear explosion, is a radioactive planet; without radiation, life would not exist. And while radiation can be dangerous, it is also deeply misunderstood and often mistakenly feared. Now Robert Peter Gale, M.D,—the doctor to whom concerned governments turned in the wake of the Chernobyl and Fukushima disasters—in collaboration with medical writer Eric Lax draws on an exceptional depth of knowledge to correct myths and establish facts. Exploring what have become trigger words for anxiety—nuclear energy and nuclear weapons, uranium, plutonium, iodine-131, mammogram, X-ray, CT scan, threats to the food chain—the authors demystify the science and dangers of radiation, and examine its myriad benefits, from safely sterilizing our food to the relatively low-risk fuel alternative of nuclear energy. This is the book for all readers who have asked themselves questions such as: What kinds of radiation, and what degree of exposure, cause cancer? What aftereffects have nuclear accidents and bombs had? Does radiation increase the likelihood of birth defects? And how does radiation work? Hugely illuminating, Radiation is the definitive road map to our post-Chernobyl, post-Fukushima world.

    The Collapse of Complex Societies, though written by an archaeologist, will therefore strike a chord throughout the social sciences. Any explanation of societal collapse carries lessons not just for the study of ancient societies, but for the members of all such societies in both the present and future. Dr. Tainter describes nearly two dozen cases of collapse and reviews more than 2000 years of explanations. He then develops a new and far-reaching theory that accounts for collapse among diverse kinds of societies, evaluating his model and clarifying the processes of disintegration by detailed studies of the Roman, Mayan and Chacoan collapses.

    . . . An extraordinary book.”—Anne Eisenberg, Scientific AmericanA companion to the man-made landscape that reveals how our industrial environment can be as dazzling as the natural world. Replete with the author's striking photographs, "Infrastructure" is a unique and spectacular guide, exploring all the major "ecosystems" of our modern industrial world, revealing what the structures are and why they're there, and uncovering beauty in unexpected places--awakening and fulfilling a curiosity you didn't know you had. Covering agriculture, resources, energy, communication, transportation, manufacturing, and waste, this is the "Book of Everything" for the industrial landscape. The objects that fill our everyday environment are streetlights, railroad tracks, antenna towers, highway overpasses, power lines, satellite dishes, and thousands of other manufactured items, many of them so familiar we hardly notice them. Larger and more exotic facilities have transformed vast tracts of the landscape: coal mines, nuclear power plants, grain elevators, oil refineries, and steel mills, to name a few. "Infrastructure" is a compelling and clear guide for those who want to explore and understand this mysterious world we've made for ourselves. 500 color illustrations.ContentsPreface1.

     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.

    In response, Jamail embarks on a journey to the geographical front lines of this crisis—from Alaska to Australia’s Great Barrier Reef, via the Amazon rainforest—in order to discover the consequences to nature and to humans of the loss of ice.We follow Jamail as he scales Denali, the highest peak in North America, dives in the Pacific only to find ghostly coral reefs, and explores the tundra of St. Paul Island where he meets the last subsistence seal hunters of the Bering Sea and witnesses its melting glaciers. Accompanied by climate scientists and people whose families have fished, farmed, and lived in the areas he visits for centuries, Jamail begins to accept the fact that Earth, most likely, is in a hospice situation. Ironically, this allows him to renew his passion for the planet’s wild places, cherishing Earth in a way he has never been able to before.le we still can.

    In making these things cheap, modern commerce has transformed, governed, and devastated Earth. In A History of the World in Seven Cheap Things, Raj Patel and Jason W. Moore present a new approach to analyzing today’s planetary emergencies. Bringing the latest ecological research together with histories of colonialism, indigenous struggles, slave revolts, and other rebellions and uprisings, Patel and Moore demonstrate that throughout history, crises have always prompted fresh strategies to make the world cheap and safe for capitalism. At a time of crisis in all seven cheap things, innovative and systemic thinking is urgently required. This book proposes a radical new way of understanding—and reclaiming—the planet in the turbulent twenty-first century.

    The price of gas and food are climbing, unemployment remains high, the housing market has tanked, consumer and government debt is soaring, and the recovery is slowing. Facing the prospect of a second collapse of the global economy, humanity is desperate for a sustainable economic game plan to take us into the future.Here, Jeremy Rifkin explores how Internet technology and renewable energy are merging to create a powerful "Third Industrial Revolution." He asks us to imagine hundreds of millions of people producing their own green energy in their homes, offices, and factories, and sharing it with each other in an "energy internet," just like we now create and share information online.Rifkin describes how the five-pillars of the Third Industrial Revolution will create thousands of businesses, millions of jobs, and usher in a fundamental reordering of human relationships, from hierarchical to lateral power, that will impact the way we conduct commerce, govern society, educate our children, and engage in civic life.Rifkin's vision is already gaining traction in the international community. The European Union Parliament has issued a formal declaration calling for its implementation, and other nations in Asia, Africa, and the Americas, are quickly preparing their own initiatives for transitioning into the new economic paradigm.The Third Industrial Revolution is an insider's account of the next great economic era, including a look into the personalities and players -- heads of state, global CEOs, social entrepreneurs, and NGOs -- who are pioneering its implementation around the world.

    But did you know that the primary driver of climate change isn’t plastics, or cars, or airplanes? Did you know that it’s actually our industrialized food system? In this fascinating new book, authors Nil Zacharias and Gene Stone share new research, intriguing infographics, and compelling arguments that support what scientists across the world are beginning to affirm and uphold: By making even minimal dietary changes, anyone can have a positive, lasting impact on our planet. If you love the planet, the only way to save it is by switching out meat for plant-based meals, one bite at a time.

    Haraway offers provocative new ways to reconfigure our relations to the earth and all its inhabitants. She eschews referring to our current epoch as the Anthropocene, preferring to conceptualize it as what she calls the Chthulucene, as it more aptly and fully describes our epoch as one in which the human and nonhuman are inextricably linked in tentacular practices. The Chthulucene, Haraway explains, requires sym-poiesis, or making-with, rather than auto-poiesis, or self-making. Learning to stay with the trouble of living and dying together on a damaged earth will prove more conducive to the kind of thinking that would provide the means to building more livable futures. Theoretically and methodologically driven by the signifier SF—string figures, science fact, science fiction, speculative feminism, speculative fabulation, so far—Staying with the Trouble further cements Haraway's reputation as one of the most daring and original thinkers of our time.

    Now William Dunham gives them the attention they deserve.Dunham places each theorem within its historical context and explores the very human and often turbulent life of the creator — from Archimedes, the absentminded theoretician whose absorption in his work often precluded eating or bathing, to Gerolamo Cardano, the sixteenth-century mathematician whose accomplishments flourished despite a bizarre array of misadventures, to the paranoid genius of modern times, Georg Cantor. He also provides step-by-step proofs for the theorems, each easily accessible to readers with no more than a knowledge of high school mathematics.A rare combination of the historical, biographical, and mathematical, Journey Through Genius is a fascinating introduction to a neglected field of human creativity.

    The heat index, which measures how the temperature actually feels on the body, would hit 126 degrees by the time the day was over. Meteorologists had been warning residents about a two-day heat wave, but these temperatures did not end that soon. When the heat wave broke a week later, city streets had buckled; the records for electrical use were shattered; and power grids had failed, leaving residents without electricity for up to two days. And by July 20, over seven hundred people had perished-more than twice the number that died in the Chicago Fire of 1871, twenty times the number of those struck by Hurricane Andrew in 1992—in the great Chicago heat wave, one of the deadliest in American history.Heat waves in the United States kill more people during a typical year than all other natural disasters combined. Until now, no one could explain either the overwhelming number or the heartbreaking manner of the deaths resulting from the 1995 Chicago heat wave. Meteorologists and medical scientists have been unable to account for the scale of the trauma, and political officials have puzzled over the sources of the city's vulnerability. In Heat Wave, Eric Klinenberg takes us inside the anatomy of the metropolis to conduct what he calls a "social autopsy," examining the social, political, and institutional organs of the city that made this urban disaster so much worse than it ought to have been.Starting with the question of why so many people died at home alone, Klinenberg investigates why some neighborhoods experienced greater mortality than others, how the city government responded to the crisis, and how journalists, scientists, and public officials reported on and explained these events. Through a combination of years of fieldwork, extensive interviews, and archival research, Klinenberg uncovers how a number of surprising and unsettling forms of social breakdown—including the literal and social isolation of seniors, the institutional abandonment of poor neighborhoods, and the retrenchment of public assistance programs—contributed to the high fatality rates. The human catastrophe, he argues, cannot simply be blamed on the failures of any particular individuals or organizations. For when hundreds of people die behind locked doors and sealed windows, out of contact with friends, family, community groups, and public agencies, everyone is implicated in their demise.As Klinenberg demonstrates in this incisive and gripping account of the contemporary urban condition, the widening cracks in the social foundations of American cities that the 1995 Chicago heat wave made visible have by no means subsided as the temperatures returned to normal. The forces that affected Chicago so disastrously remain in play in America's cities, and we ignore them at our peril.

    Explaining why the whole is sometimes smarter than the sum of its parts, Johnson presents surprising examples of feedback, self-organization, and adaptive learning. How does a lively neighborhood evolve out of a disconnected group of shopkeepers, bartenders, and real estate developers? How does a media event take on a life of its own? How will new software programs create an intelligent World Wide Web? In the coming years, the power of self-organization -- coupled with the connective technology of the Internet -- will usher in a revolution every bit as significant as the introduction of electricity. Provocative and engaging, Emergence puts you on the front lines of this exciting upheaval in science and thought.

    We want to embrace renewable energy sources like wind and solar, and rely less on dirty fossil fuels. We don’t want to keep pumping so many heat-trapping gases into the atmosphere. Any transition from a North American power grid that uses mostly fossil fuels to one that is predominantly clean requires a massive building spree—billions of dollars’ worth. Enter Michael Skelly, an infrastructure builder who began working on wind energy in 2000, when many considered the industry a joke. Eight years later, Skelly helped create the second largest wind power company in the United States—which was sold for $2 billion. Wind energy was no longer funny; it was well on its way to generating a substantial percentage of the electricity in the United States. Acclaimed journalist and author of The Boom, “the best all-around book yet on fracking” (San Francisco Chronicle), Russell Gold tells the story of this pioneer whose innovations, struggles, and persistence represent the groundbreaking changes underway in American energy. InSuperpower, we meet Skelly’s financial backers, a family that pivoted from oil exploration to renewable energy; the farmers ready to embrace the new “cash crop”; the landowners prepared to go to court to avoid looking at overhead wires; and utility executives who concoct fiendish ways to block renewable energy. Gold also shows how Skelly’s innovative company, Clean Line Energy, conceived the idea for a new power grid that would allow sunlight where abundant to light up homes thousands of miles away in cloudy states, and take wind from the Great Plains to keep air conditioners running in Atlanta. Thrilling, provocative, and important, Superpower is a fascinating look at America’s future.

    Our interconnected world is susceptible to sudden and dramatic shocks and stresses: a cyber-attack, a new strain of virus, a structural failure, a violent storm, a civil disturbance, an economic blow. Through an astonishing range of stories, Judith Rodin shows how people, organizations, businesses, communities, and cities have developed resilience in the face of otherwise catastrophic challenges:• Medellin, Colombia, was once the drug and murder capital of South America. Now it’s host to international conferences and an emerging vacation destination.• Tulsa, Oklahoma, cracked the code of rapid urban development in a floodplain.• Airbnb, Toyota, Ikea, Coca-Cola, and other companies have realized the value of reducing vulnerabilities and potential threats to customers, employees, and their bottom line.• In the Mau Forest of Kenya, bottom-up solutions are critical for dealing with climate change, environmental degradation, and displacement of locals.• Following Superstorm Sandy, the Rockaway Surf Club in New York played a vital role in distributing emergency supplies.As we grow more adept at managing disruption and more skilled at resilience-building, Rodin reveals how we are able to create and take advantage of new economic and social opportunities that offer us the capacity to recover after catastrophes and grow strong in times of relative calm.
