Our beaches are eroding, sinking, washing out right under our houses, hotels, bridges; vacation dreamlands become nightmare scenes of futile revetments, fills, groins, what have you-all thrown up in a frantic defense against the natural system. The romantic desire to live on the seashore is in doomed conflict with an age-old pattern of beach migration. Yet it need not be so. Conservationist Wallace Kaufman teams up with marine geologist Orrin H. Pilkey Jr. , in an evaluation of America's beaches from coast to coast, giving sound advice on how to judge a safe beach development from a dangerous one and how to live at the shore sensibly and safely.
An internationally recognized expert on the geology of barrier islands, Orrin H. Pilkey is one of the rare academics who engages in public advocacy about science-related issues. He has written dozens of books and articles explaining coastal processes to lay readers, and he is a frequent and outspoken interviewee in the mainstream media. Here, the colorful scientist takes on climate change deniers in an outstanding and much-needed primer on the science of global change and its effects. After explaining the greenhouse effect, Pilkey, writing with son Keith, turns to the damage it is causing: sea level rise, ocean acidification, glacier and sea ice melting, changing habitats, desertification, and the threats to animals, humans, coral reefs, marshes, and mangroves. These explanations are accompanied by Mary Edna Fraser's stunning batiks depicting the large-scale arenas in which climate change plays out. The Pilkeys directly confront and rebut arguments typically advanced by global change deniers. Particularly valuable are their discussions of "Climategate," a manufactured scandal that undermined respect for the scientific community, and the denial campaigns by the fossil fuel industry, which they compare to the tactics used by the tobacco companies a generation ago to obfuscate findings on the harm caused by cigarettes.
Noted coastal geologist Orrin Pilkey and environmental scientist Linda Pilkey-Jarvis show that the quantitative mathematical models policy makers and government administrators use to form environmental policies are seriously flawed. Based on unrealistic and sometimes false assumptions, these models often yield answers that support unwise policies. Writing for the general, nonmathematician reader and using examples from throughout the environmental sciences, Pilkey and Pilkey-Jarvis show how unquestioned faith in mathematical models can blind us to the hard data and sound judgment of experienced scientific fieldwork. They begin with a riveting account of the extinction of the North Atlantic cod on the Grand Banks of Canada. Next they engage in a general discussion of the limitations of many models across a broad array of crucial environmental subjects. The book offers fascinating case studies depicting how the seductiveness of quantitative models has led to unmanageable nuclear waste disposal practices, poisoned mining sites, unjustifiable faith in predicted sea level rise rates, bad predictions of future shoreline erosion rates, overoptimistic cost estimates of artificial beaches, and a host of other thorny problems. The authors demonstrate how many modelers have been reckless, employing fudge factors to assure "correct" answers and caring little if their models actually worked. A timely and urgent book written in an engaging style, Useless Arithmetic evaluates the assumptions behind models, the nature of the field data, and the dialogue between modelers and their "customers."
Take this book to the beach; it will open up a whole new world. Illustrated throughout with color photographs, maps, and graphics, it explores one of the planet's most dynamic environments--from tourist beaches to Arctic beaches strewn with ice chunks to steaming hot tropical shores. The World's Beaches tells how beaches work, explains why they vary so much, and shows how dramatic changes can occur on them in a matter of hours. It discusses tides, waves, and wind; the patterns of dunes, washover fans, and wrack lines; and the shape of berms, bars, shell lags, cusps, ripples, and blisters. What is the world's longest beach? Why do some beaches sing when you walk on them? Why do some have dark rings on their surface and tiny holes scattered far and wide? This fascinating, comprehensive guide also considers the future of beaches, and explains how extensively people have affected them--from coastal engineering to pollution, oil spills, and rising sea levels.
