Book Description
Tide gauges show that global sea level has risen about 7 inches during the 20th century, and recent satellite data show that the rate of sea-level rise is accelerating. As Earth warms, sea levels are rising mainly because ocean water expands as it warms; and water from melting glaciers and ice sheets is flowing into the ocean. Sea-level rise poses enormous risks to the valuable infrastructure, development, and wetlands that line much of the 1,600 mile shoreline of California, Oregon, and Washington. As those states seek to incorporate projections of sea-level rise into coastal planning, they asked the National Research Council to make independent projections of sea-level rise along their coasts for the years 2030, 2050, and 2100, taking into account regional factors that affect sea level. Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future explains that sea level along the U.S. west coast is affected by a number of factors. These include: climate patterns such as the El Niño, effects from the melting of modern and ancient ice sheets, and geologic processes, such as plate tectonics. Regional projections for California, Oregon, and Washington show a sharp distinction at Cape Mendocino in northern California. South of that point, sea-level rise is expected to be very close to global projections. However, projections are lower north of Cape Mendocino because the land is being pushed upward as the ocean plate moves under the continental plate along the Cascadia Subduction Zone. However, an earthquake magnitude 8 or larger, which occurs in the region every few hundred to 1,000 years, would cause the land to drop and sea level to suddenly rise.

Book Description
The tragedy of the 2004 Indian Ocean tsunami has led to a rapid expansion in science directed at understanding tsunami and mitigating their hazard. A remarkable cross-section of this research was presented in the session: Tsunami Generation and Hazard, at the International Union of Geodesy and Geophysics XXIV General Assembly in Perugia, held in July of 2007. Over one hundred presentations were made at this session, spanning topics ranging from paleotsunami research, to nonlinear shallow-water theory, to tsunami hazard and risk assessment. A selection of this work, along with other contributions from leading tsunami scientists, is published in detail in the 28 papers of this special issue of Pure and Applied Geophysics: Tsunami Science Four Years After the Indian Ocean Tsunami. Part I of this issue includes 14 papers covering the state-of-the-art in tsunami modelling and hazard assessment. Another 14 papers are published in Part II focusing on observations and data analysis.

Book Description
While the coast of the Pacific Northwest becomes ever more populated and developed, its beaches and cliffs continue to be altered by ocean currents and winter storms. Coastal oceanographer Paul Komar reminds readers of the area's geological and cultural history and the ever-present problem of erosion. He issues an urgent call for changes in shoreline management and attitudes toward development. 41 figures. 20 maps. 112 photos.

Book Description
Post-World War II Oregon was a place of optimism and growth, a spectacular natural region from ocean to high desert that seemingly provided opportunity in abundance. With the passing of time, however, Oregon’s citizens — rural and urban — would find themselves entangled in issues that they had little experience in resolving. The same trees that provided income to timber corporations, small mill owners, loggers, and many small towns in Oregon, also provided a dramatic landscape and a home to creatures at risk. The rivers whose harnessing created power for industries that helped sustain Oregon’s growth — and were dumping grounds for municipal and industrial wastes — also provided passageways to spawning grounds for fish, domestic water sources, and recreational space for everyday Oregonians. The story of Oregon’s accommodation to these divergent interests is a divisive story between those interested in economic growth and perceived stability and citizens concerned with exercising good stewardship towards the state’s natural resources and preserving the state’s livability. In his second volume of Oregon’s environmental history, William Robbins addresses efforts by individuals and groups within and outside the state to resolve these conflicts. Among the people who have had roles in this process, journalists and politicians Richard Neuberger and Tom McCall left substantial legacies and demonstrated the ambiguities inherent in the issues they confronted.
