Grand Canyon For Sale is a carefully researched investigation of the precarious future of America's public lands: our national parks, forests, wildlife refuges, monuments, and wildernesses. Taking the Grand Canyon as his key example, and using on-the-ground reporting as well as scientific research, Stephen Nash shows how accelerating climate change will dislocate wildlife populations and vegetation across hundreds of thousands of square miles of the national landscape. In addition, a growing political movement, well financed and occasionally violent, is fighting to break up these federal lands and return them to state, local, and private control. That scheme would foreclose the future for many wild species, which are part of our irreplaceable natural heritage, and also would devastate our national parks, forests, and other public lands. To safeguard wildlife and their habitats, it is essential to consolidate protected areas and prioritize natural systems over mining, grazing, drilling, and logging. Grand Canyon For Sale provides an excellent overview of the physical and biological challenges facing public lands.The book also exposes and shows how to combat the political activity that threatens these places in the U.S. today.

The emergence of high performance computers and sophisticated software technology has led to significant advances in the development and application of operations research. In turn, the growing complexity of operations research models has posed an increasing challenge to computational methodology and computer technology. This volume focuses on recent advances in the fields of computer science and operations research, on the impact of technological innovation on these disciplines, and on the close interaction between them. The papers cover many relevant topics: computational probability; design and analysis of algorithms; graphics, heuristic search and learning; knowledge-based systems; large-scale optimization; logic modelling and computation; modelling languages; parallel computation; simulation; and telecommunications.

Climate disruption is often discussed on a global scale, affording many a degree of detachment from what is happening in their own backyards. Yet the consequences of global warming are of an increasingly acute and serious nature.In Virginia Climate Fever, environmental journalist Stephen Nash brings home the threat of climate change to the state of Virginia. Weaving together a compelling mix of data and conversations with both respected scientists and Virginians most immediately at risk from global warming’s effects, the author details how Virginia’s climate has already begun to change. In engaging prose and layman’s terms, Nash argues that alteration in the environment will affect not only the state’s cities but also hundreds of square miles of urban and natural coastal areas, the 60 percent of the state that is forested, the Chesapeake Bay, and the near Atlantic, with accompanying threats such as the potential spread of infectious disease. The narrative offers striking descriptions of the vulnerabilities of the state’s many beautiful natural areas, around which much of its tourism industry is built.While remaining respectful of the controversy around global warming, Nash allows the research to speak for itself. In doing so, he offers a practical approach to and urgent warning about the impending impact of climate change in Virginia.

Archaeologists with expertise in stratigraphy, ceramic dating, obsidian hydration, and luminescence dating present historical and nontechnical reviews of the growth, development, and application of their techniques.
