Acknowledging the impending worldwide catastrophe of rising seas in the twenty-first century, Orrin H. Pilkey and Keith C. Pilkey outline the impacts on the United States' shoreline and argue that the only feasible response along much of the U.S. shoreline is an immediate and managed retreat.

The geologists Orrin H. Pilkey and J. Andrew G. Cooper sound the alarm in this frank assessment of our current relationship with beaches and the grim future if we do not change the way we understand and treat our irreplaceable shores.

Melting ice sheets and warming oceans are causing the seas to rise. By the end of this century, hundreds of millions of people living at low elevations along coasts will be forced to retreat to higher and safer ground. Because of sea-level rise, major storms will inundate areas farther inland and will lay waste to critical infrastructure, such as water-treatment and energy facilities, creating vast, irreversible pollution by decimating landfills and toxic-waste sites. This big-picture, policy-oriented book explains in gripping terms what rising oceans will do to coastal cities and the drastic actions we must take now to remove vulnerable populations.The authors detail specific threats faced by Miami, New Orleans, New York, and Amsterdam. Aware of the overwhelming social, political, and economic challenges that would accompany effective action, they consider the burden to the taxpayer and the logistics of moving landmarks and infrastructure, including toxic-waste sites. They also show readers the alternative: thousands of environmental refugees, with no legitimate means to regain what they have lost. The authors conclude with effective approaches for addressing climate-change denialism and powerful arguments for reforming U.S. federal coastal management policies.

From the Carolina Outer Banks to New York's Fire Island, from Iceland to the Netherlands and Colombia to Vietnam, barrier islands protect much of the world's coastlines from the ravages of the sea. This title identifies coastal plains, Arctic, and delta - each with its own geological characteristics and particular morphologies.

An internationally recognized expert on the geology of barrier islands takes on climate change deniers in an outstanding and much-needed primer on the science of global change and its effects.

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.

Part of the "Living with the Shore" series, this book provides a guide to one of America's most popular shorelines. It features diagrams and photographs that illustrate coastal processes and aid in understanding the impact of hurricanes and northeasters, wave and current dynamics, as well as the environmental destruction due to over-development.

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 "e;correct"e; 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 "e;customers."e;

On Shishmaref Island in Alaska, homes are being washed into the sea. In the South Pacific, small island nations face annihilation by encroaching waters. In coastal Louisiana, an area the size of a football field disappears every day. For these communities, sea level rise isn't a distant, abstract fear: it's happening now and it's threatening their way of life.In The Rising Sea, Orrin H. Pilkey and Rob Young warn that many other coastal areas may be close behind. Prominscientists predict that the oceans may rise by as much as seven feet in the next hundred years. That means coastal cities will be forced to construct dikes and seawalls or to move buildings, roads, pipelines, and railroads to avert inundation and destruction.The question is no longer whether climate change is causing the oceans to swell, but by how much and how quickly. Pilkey and Young deftly guide readers through the science, explaining the facts and debunking the claims of industry-sponsored "e;skeptics."e; They also explore the consequences for fish, wildlife-and people.While rising seas are now inevitable, we are far from helpless. By making hard choices-including uprooting citizens, changing where and how we build, and developing a coordinated national response-we can save property, and ultimately lives. With unassailable research and practical insights, The Rising Sea is a critical first step in understanding the threat and keeping our heads above water.
