A handbook for scholars, students, policy makers, journalists, and peace and environmental activists.A handbook for scholars, students, policy makers, journalists, and peace and environmental activists, Nuclear Wastelands provides concise histories of the development of nuclear weapons programs of every declared and de facto nuclear weapons power, as well as detailed surveys of the health and environmental effects of this development both in these countries and in non-nuclear nations involved in nuclear weapons testing and uranium mining. Among the more obvious but largely deferred costs of the Cold War are those related to the management of radioactive waste. The world is burdened with thousands of unwanted nuclear devices and mounting surpluses of weapons-grade plutonium and enriched uranium. In addition, the process of weapons production and testing has left many lands, aquifers, rivers, lakes, and seas contaminated by a multitude of weapons-related poisons. This book follows the production process step by step and country by country from uranium mining to the final assembly and storage of weapons, analyzing the potential hazards of each step and compiling the most complete information available on the actual health and environmental effects, in each country involved. Nuclear Wastelands includes a wealth of information that has only recently come to light, particularly on the nuclear weapons program of the former Soviet Union. It also features critical analyses of official public communications concerning the health and environmental consequences of nuclear weapons production, bringing to light governmental secrecy and outright deception that have led to the subversion of democratic principles, and have camouflaged the damage done to the very people and lands the weapons were meant to safeguard.

Net zero emissions is only the beginning. Smith explains the need for carbon dioxide removal and even solar radiation management to preserve our societies and ecosystems.

Since 1945, the United States has manufactured and deployed more than 70,000 nuclear weapons to deter and if necessary fight a nuclear war. Some observers believe the absence of a third world war confirms that these weapons were a prudent and cost-effective response to the uncertainty and fear surrounding the Soviet Union's military and political ambitions during the cold war. As early as 1950, nuclear weapons were considered relatively inexpensive— providing "a bigger bang for a buck"—and were thoroughly integrated into U.S. forces on that basis. Yet this assumption was never validated. Indeed, for more than fifty years scant attention has been paid to the enormous costs of this effort—more than $5 trillion thus far—and its short and long-term consequences for the nation. Based on four years of extensive research, Atomic Audit is the first book to document the comprehensive costs of U.S. nuclear weapons, assembling for the first time anywhere the actual and estimated expenditures for the program since its creation in 1940. The authors provide a unique perspective on U.S. nuclear policy and nuclear weapons, tracking their development from the Manhattan Project of World War II to the present day and assessing each aspect of the program, including research, development, testing, and production; deployment; command, control, communications, and intelligence; and defensive measures. They also examine the costs of dismantling nuclear weapons, the management and disposal of large quantities of toxic and radioactive wastes left over from their production, compensation for persons harmed by nuclear weapons activities, nuclear secrecy, and the economic implications of nuclear deterrence. Utilizing archival and newly declassified government documents and data, this richly documented book demonstrates how a variety of factors—the open-ended nature of nuclear deterrence, faulty assumptions about the cost-effectiveness of nuclear weapons, regular misrepresentati

The central thesis of this book is that the genetic structures of living beings are internal biological expressions of the ecosystems they need to survive. That is why living beings contribute to the reproduction of ecosystems by their everyday acts of living, in a global-scale symbiosis. Inter-species genetic engineering creates new types of living beings, which could not arise naturally and which are being introduced without a sound understanding of their ecological impacts. The potential for nasty ecological surprises, possibly greater than anything seen with chemicals, is outlined in this monograph, which is based on fundamental theoretical arguments, illustrated with many examples.

In the 1970s the world became aware of a huge danger: the destruction of the stratospheric ozone layer by CFCs escaping into the atmosphere, and the damage this could do to human health and the food chain. So great was the threat that by 1987 the UN had succeeded in coordinating an international treaty to phase out emissions; which, over the following 15 years has been implemented. It has been hailed as an outstanding success. It needed the participation of all the parties: governments, industry, scientists, campaigners, NGOs and the media, and is a model for future treaties. This volume provides the authoritative and comprehensive history of the whole process from the earliest warning signs to the present. It is an invaluable record for all those involved and a necessary reference for future negotiations to a wide range of scholars, students and professionals.

Nature is fragile, environmentalists often tell us. But the lesson of this book is that it is not so. The truth is far more worrying. Nature is strong and packs a serious counterpunch . . . Global warming will very probably unleash unstoppable planetary forces. And they will not be gradual. The history of our planet's climate shows that it does not do gradual change. Under pressure, whether from sunspots or orbital wobbles or the depredations of humans, it lurches-virtually overnight. —from the Introduction Fred Pearce has been writing about climate change for eighteen years, and the more he learns, the worse things look. Where once scientists were concerned about gradual climate change, now more and more of them fear we will soon be dealing with abrupt change resulting from triggering hidden tipping points. Even President Bush's top climate modeler, Jim Hansen, warned in 2005 that "we are on the precipice of climate system tipping points beyond which there is no redemption." As Pearce began working on this book, normally cautious scientists beat a path to his door to tell him about their fears and their latest findings. With Speed and Violence tells the stories of these scientists and their work-from the implications of melting permafrost in Siberia and the huge river systems of meltwater beneath the icecaps of Greenland and Antarctica to the effects of the "ocean conveyor" and a rare molecule that runs virtually the entire cleanup system for the planet. Above all, the scientists told him what they're now learning about the speed and violence of past natural climate change-and what it portends for our future. With Speed and Violence is the most up-to-date and readable book yet about the growing evidence for global warming and the large climatic effects it may unleash.

Why did Al Gore, after angry opposition to the Vietnam War, submit to the draft? What happened in Vietnam that made him sullen and bitter? After renouncing politics, what set him back on the track mapped out for him? What made him claim (falsely) that he invented the Internet? How closely is he allied with the tobacco industry? What is the real nature of his partnership with Bill Clinton? How was it altered by the Lewinsky affair? INVENTING AL GORE addresses these issues and more as it unveils the true motivations, ideals, and idiosyncracies of one of Washington's most inscrutable men. Bill Turque, who covered both of Gore's vice presidential campaigns and the Clinton White House, draws on extensive access to Gore's key advisers, friends, and family. He unmasks a man who in private can sing and dance to George Strait's music but in public measures every comment and gesture with legendary caution. As Turque details, Gore's great political albatross -- a lack of empathy -- was hatched during his lonely childhood as the product of ambitious political parents who groomed him for the presidency. Turque's keen analysis also uncovers the genesis of Gore's questionable fund-raising and of a political platform laden with worthy but emotionally safe planks such as bioethics, global warming, and the Internet. In addition, Inventing Al Gore illuminates how personal tragedies have shaped his political life and the remarkable influence that women, from his mother to Naomi Wolf, have had on his career. INVENTING AL GORE reveals Gore to be one of the most intelligent, idealistic men in Washington, yet one who is repeatedly prone to prevarication, exaggeration, and avoidance of hard issues. Turque offers a meticulously researched narrative filled with colorful, insightful details that sharpen the debate over whether Gore can outgrow his limitations and excel in the office he has prepared for all his life.
