Scenic vistas in most U.S. parklands are diminished by haze that reduces contrast, washes out colors, and renders distant landscape features indistinct or invisible. Protecting Visibility in National Parks and Wilderness Areas describes the current understanding of the nature and extent of haze in various regions of the United States. The book addresses the scientific and legal framework of efforts to protect and improve visibility, as well as methods for assessing the relative importance of anthropogenic emission sources that contribute to haze in national parks and for considering various alternative source control measures. The volume provides guidance on how to make progress toward the national goal of correcting and preventing visibility impairment due to human activities affecting large national parks and wilderness areas.

“Human beings have been smart enough to turn nature to their ends, generate vast wealth for themselves, and double their average life span. But are they smart enough to solve the problems of the 21st century?” -- Thomas Homer-Dixon In The Ingenuity Gap, Thomas Homer-Dixon, "global guru" (the Toronto Star), asks: is our world becoming too complex, too fast-paced to manage? The challenges facing us converge, intertwine, and remain largely beyond our ken. Most of suspect the "experts don't really know what's going on; that as a species we've released forces that are neither managed nor manageable. We are fast approaching a time when we may no longer be able to control a world that increasingly exceeds our grasp. This is "the ingenuity gap" -- the term coined by Thomas Homer-Dixon -- the critical gap between our need for practical, innovative ideas to solve complex problems and our actual supply of those ideas. Through gripping narrative stories and incidents that exemplify his arguments, he takes us on a world tour that begins with a heartstopping description of the tragic crash of United Airlines Flight 232 from Denver to Chicago and includes Las Vegas in its desert, a wilderness beach in British Columbia, and his solitary search for a little girl in Patna, India. He shows how, in our complex world, while poor countries are particularly vulnerable to ingenuity gaps, our own rich countries are not immune, and we are caught between a requirement for ingenuity and an increasingly uncertain supply. When the gap widens, political disintegration and violent upheaval can result, reaching into our own economies and daily lives in subtle ways. In compelling, lucid, prose, he makes real the problems we face and suggests how we might overcome them.

Managing the nation's air quality is a complex undertaking, involving tens of thousands of people in regulating thousands of pollution sources. The authors identify what has worked and what has not, and they offer wide-ranging recommendations for setting future priorities, making difficult choices, and increasing innovation. This new book explores how to better integrate scientific advances and new technologies into the air quality management system. The volume reviews the three-decade history of governmental efforts toward cleaner air, discussing how air quality standards are set and results measured, the design and implementation of control strategies, regulatory processes and procedures, special issues with mobile pollution sources, and more. The book looks at efforts to spur social and behavioral changes that affect air quality, the effectiveness of market-based instruments for air quality regulation, and many other aspects of the issue. Rich in technical detail, this book will be of interest to all those engaged in air quality management: scientists, engineers, industrial managers, law makers, regulators, health officials, clean-air advocates, and concerned citizens.
