Most of the earth's population would survive the immediate horrors of a nuclear holocaust, but what long-term climatological changes would affect their ability to secure food and shelter? This sobering book considers the effects of fine dust from ground-level detonations, of smoke from widespread fires, and of chemicals released into the atmosphere. The authors use mathematical models of atmospheric processes and data from natural situations--e.g., volcanic eruptions and arctic haze--to draw their conclusions. This is the most detailed and comprehensive probe of the scientific evidence published to date.

Opportunities in Chemistry is based on the contributions of hundreds of American chemists in academia and industry and should be taken as the best available consensus of the chemical community regarding its intellectual frontiers and the economic opportunities that lie beyond them," says Science. This volume addresses the direction in which today's chemical research is heading, including recent developments, technological applications, and the ways advances in chemistry can be used to improve the human condition. In addition, the book examines economic and political implications of chemical research and lists resources for basic research and education in the chemical sciences.

How damaging is acid rain? Current opinions differ widely, in part because for every proposed link between acid rain and adverse environmental effects an alternative explanation based on other phenomena can be or has been proposed, and in many cases cannot be readily dismissed. The specific areas addressed in this volume include the emissions of sulfur and nitrogen oxides, precipitation chemistry, atmospheric sulfates and visibility, surface water chemistry, sediment chemistry and abundance of diatom taxa, fish populations, and forest productivity. The book then draws conclusions about the acid deposition-phenomenon relationship, identifying phenomena which are directly acid deposition-caused and suggesting others apparently caused by human activities unrelated to acid deposition.

Experts agree that the nation would benefit if more young people "turned on" to the sciences. This book is designed as a tool to do just that. It is based on Opportunities in Chemistry, a National Research Council publication that incorporated the contributions of 350 researchers working at the frontiers of the field. Chemistry educators Janice A. Coonrod and the late George C. Pimentel revised the material to capture the interest of today's student. A broad and highly readable survey, the volume explores: * The role of chemistry in attacking major problems in environmental quality, food production, energy, health, and other important areas. * Opportunities at the leading edge of chemistry, in controlling basic chemical reactions and working at the molecular level. * Working with lasers, molecular beams, and other sophisticated measurement techniques and tools available to chemistry researchers. The book concludes with a discussion of chemistry's role in society's risk-benefit decisions and a review of career and educational opportunities.

Mono Basin is a closed hydrologic basin spanning the border between California and Nevada. Los Angeles has been diverting streams since 1941 that normally would flow into Mono Lake. It has been predicted that continued diversion will have major ecological consequences for the natural resources of the Mono Basin National Forest Scenic Area. This book studies the ecological risk assessment that considers the effects of water diversions on an inland saline lake. It examines the hydrology of the Mono Basin, investigates the lake's physical and chemical systems, studies the biological relationships, and predicts the effects of changes in lake levels on the ecosystem.

Ozone depletion in the stratosphere and increases in greenhouse gases in the troposphere are both subjects of growing concern--even alarm--among scientists, policymakers, and the public. At the same time, recent data show that these atmospheric developments are interconnected and in turn profoundly affect climatic conditions. This volume presents the most up-to-date data and theories available on ozone depletion, greenhouse gases, and climatic change. These questions and more are addressed: What is the current understanding of the processes that destroy ozone in the atmosphere? What role do greenhouse gases play in ozone depletion?

When waterfowl began to die from selenium poisoning at Kesterson National Wildlife Refuge in California's San Joaquin Valley, considerable alarm arose among environmental and agricultural specialists. This new volume suggests that Kesterson is not a unique problem and the events there offer important lessons for the future. Irrigation-Induced Water Quality Problems uses the San Joaquin experience to suggest how we can prepare for similar problems elsewhere. As one committee member put it, "There will be elsewheres"--trace elements and organic contaminants are being concentrated by irrigation in many river basins. This book addresses how the Kesterson crisis developed, how irrigation can endanger water quality, and how economic, legal, and other factors impede our ability to respond to water quality problems. The committee explores how to study these problems, unraveling complex issues and clarifying the varying perspectives of farmers, environmentalists, scientists, and other key figures.This dispassionate analysis of a controversial topic will be useful to policymakers, resource managers, and agricultural specialists and farmers, as well as specialists in hydrology, water quality, irrigation, law, and environmental quality. It will also be useful as a case study in the environmental policy classroom.

Geodesy has undergone technological and theoretical changes of immense proportions since the launching of Sputnik. The accuracy of current satellite geodetic data has approached the centimeter level and will improve by one or two orders of magnitude over the next decade. This bodes well for the application of geodetic data to the solution of problems in solid earth, oceanic and atmospheric sciences. The report Geodesy in the Year 2000 addresses many areas of investigation that will benefit from this improvement in accuracy.
