Most of us are familiar with the term climate change but few of us understand the science behind it. We don’t fully comprehend how climate change will affect us, and for that reason we might not consider it as pressing a concern as, say, housing prices or unemployment. This book explains the scientific knowledge about global climate change clearly and concisely in engaging, nontechnical language, describes how it will affect all of us, and suggests how government, business, and citizens can take action against it.
Climate engineeringâ€”which could slow the pace of global warming by injecting reflective particles into the upper atmosphereâ€”has emerged in recent years as an extremely controversial technology. And for good reason: it carries unknown risks and it may undermine commitments to conserving energy. Some critics also view it as an immoral human breach of the natural world. The latter objection, David Keith argues in A Scientistâ€™s Case for Climate Engineering, is groundless; we have been using technology to alter our environment for years.
The future is not what it used to be because we can no longer rely on the comforting assumption that it will resemble the past. Past abundance of fuel, for example, does not imply unending abundance. Infinite growth on a finite planet is not possible.
The vast majority of scientists agree that human activity has significantly increased greenhouse gases in the atmosphere--most dramatically since the 1970s. Yet global warming skeptics and ill-informed elected officials continue to dismiss this broad scientific consensus.
The biosphere—the Earth’s thin layer of life—dates from nearly four billion years ago, when the first simple organisms appeared. Many species have exerted enormous influence on the biosphere’s character and productivity, but none has transformed the Earth in so many ways and on such a scale as Homo sapiens. In Harvesting the Biosphere, Vaclav Smil offers an interdisciplinary and quantitative account of human claims on the biosphere’s stores of living matter, from prehistory to the present day.
Human survival depends on a continuing supply of energy, but the need for ever-increasing amounts of it poses a dilemma: How can we find energy sources that are sustainable and ways to convert and utilize energy that are more efficient? This widely used textbook is designed for advanced undergraduate and graduate students as well as others who have an interest in exploring energy resource options and technologies with a view toward achieving sustainability on local, national, and global scales.
We will not find â€śexposure to burning coalâ€ť listed as the cause of death on a single death certificate, but tens of thousands of deaths from asthma, chronic obstructive pulmonary disease, lung cancer, heart attacks, strokes, and other illnesses are clearly linked to coal-derived pollution. As politicians and advertising campaigns extol the virtues of â€śclean coal,â€ť the dirty secret is that coal kills. In The Silent Epidemic, Alan Lockwood, a physician, describes and documents the adverse health effects of burning coal.
Greater knowledge and transparency are often promoted as the keys to solving a wide array of governance problems. In Instituting Nature, Andrew Mathews describes Mexicoâ€™s efforts over the past hundred years to manage its forests through forestry science and biodiversity conservation. He shows that transparent knowledge was produced not by official declarations or scientistsâ€™ expertise but by encounters between the relatively weak forestry bureaucracy and the indigenous people who manage and own the pine forests of Mexico.
Biological sewage treatment, like electricity, power generation, telephones, and mass transit, has been a key technology and a major part of the urban infrastructure since the late nineteenth century. But sewage treatment plants are not only a ubiquitous component of the modern city, they are also ecosystems--a hybrid variety that incorporates elements of both nature and industry and embodies multiple contradictions.
Over the course of nearly thirty years, the environmental justice movement has changed the politics of environmental activism and influenced environmental policy. In the process, it has turned the attention of environmental activists and regulatory agencies to issues of pollution, toxics, and human health as they affect ordinary people, especially people of color. This book argues that the environmental justice movement has also begun to transform science and engineering.
