"One of those rare books that’s both sweeping and specific, scholarly and readable…What makes the book stand out is its wealth of historical detail." —Elizabeth Kolbert, The New Yorker The history of the twentieth century is most often told through its world wars, the rise and fall of communism, or its economic upheavals. In his startling book, J. R. McNeill gives us our first general account of what may prove to be the most significant dimension of the twentieth century: its environmental history. To a degree unprecedented in human history, we have refashioned the earth's air, water, and soil, and the biosphere of which we are a part. Based on exhaustive research, McNeill's story—a compelling blend of anecdotes, data, and shrewd analysis—never preaches: it is our definitive account. This is a volume in The Global Century Series (general editor, Paul Kennedy).
" ... Concise explanations and descriptions - easily read and readily understood - of what we know of the chain of events and processes that connect the Sun to the Earth, with special emphasis on space weather and Sun-Climate."--Dear Reader.
The second edition of this fully integrated introductory text for courses in environmental studies and physical geography builds on the resounding success of the first edition, providing a comprehensive account of modern environmental issues and the physical and socio-economic framework in which they are set. It explains the principles and applications of the different parts of the Earth's system: the lithosphere, atmosphere, hydrosphere and the biosphere, and explains the interrelationships within and between these systems. It explores the present environmental crisis, examines how the planet Earth fits into the wider universe and explores human-environment interactions.
Natural and man-made changes in the environment create a very complex picture. This book analyzes this picture and provides snapshots of different areas of interest and to make suggestions for future work on cleaning and stabilizing the Earth's environment. Starting with conventional energy generation and moving on to renewable energies, this book analyzes and calculates their environmental impact and the lesser known aspects of their "cradle-to-grave" life cycle such as the irreversible environmental damage done during the manufacturing of solar and wind equipment and during the installation, operation, and decommissioning of large scale hydro, solar, and wind power plants.
How are human societies changing the global environment? Is sustainable development really possible? Can environmental risks be avoided? Is our experience of nature changing? This book shows how questions about the environment cannot be properly answered without taking a sociological approach. It provides a comprehensive guide to the ways in which sociologists have responded to the challenge of environmental issues as diverse as global warming, ozone depletion, biodiversity loss and marine pollution. It also covers sociological ideas such as risk, interpretations of nature, environmental realism, ecological modernization and globalization. Environmentalism and green politics are also introduced. Unlike many other texts in the field, the book takes a long-term view, locating environmental dilemmas within the context of social development and globalization. The Environment: A Sociological Introduction is unique in presenting environmental issues at an introductory level that assumes no specialist knowledge on the part of readers. The book is written in a remarkably clear and accessible style, and uses a rich range of empirical examples from across the globe to illustrate key debates. A carefully assembled glossary and annotated further reading suggestions also help to bring ideas to life. The book will be a valuable resource for students in a range of disciplines, including sociology, geography and the environmental sciences, but also for anyone who wants to get to grips with contemporary environmental debates.
NEW YORK TIMES BESTSELLER NATIONAL BESTSELLER In this urgent, singularly authoritative book, Bill Gates sets out a wide-ranging, practical--and accessible--plan for how the world can get to zero greenhouse gas emissions in time to avoid an irreversible climate catastrophe. Bill Gates has spent a decade investigating the causes and effects of climate change. With the help and guidance of experts in the fields of physics, chemistry, biology, engineering, political science and finance, he has focused on exactly what must be done in order to stop the planet's slide toward certain environmental disaster. In this book, he not only gathers together all the information we need to fully grasp how important it is that we work toward net-zero emissions of greenhouse gases but also details exactly what we need to do to achieve this profoundly important goal. He gives us a clear-eyed description of the challenges we face. He describes the areas in which technology is already helping to reduce emissions; where and how the current technology can be made to function more effectively; where breakthrough technologies are needed, and who is working on these essential innovations. Finally, he lays out a concrete plan for achieving the goal of zero emissions--suggesting not only policies that governments should adopt, but what we as individuals can do to keep our government, our employers and ourselves accountable in this crucial enterprise. As Bill Gates makes clear, achieving zero emissions will not be simple or easy to do, but by following the guidelines he sets out here, it is a goal firmly within our reach.
Mathematics for the Environment shows how to employ simple mathematical tools, such as arithmetic, to uncover fundamental conflicts between the logic of human civilization and the logic of Nature. These tools can then be used to understand and effectively deal with economic, environmental, and social issues. With elementary mathematics, the book se
Taking an interdisciplinary approach, this book explores what makes the conditions on Earth 'just right' to sustain life.
