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.

Climate change is occurring, is caused largely by human activities, and poses significant risks for-and in many cases is already affecting-a broad range of human and natural systems. The compelling case for these conclusions is provided in Advancing the Science of Climate Change, part of a congressionally requested suite of studies known as America's Climate Choices. While noting that there is always more to learn and that the scientific process is never closed, the book shows that hypotheses about climate change are supported by multiple lines of evidence and have stood firm in the face of serious debate and careful evaluation of alternative explanations. As decision makers respond to these risks, the nation's scientific enterprise can contribute through research that improves understanding of the causes and consequences of climate change and also is useful to decision makers at the local, regional, national, and international levels. The book identifies decisions being made in 12 sectors, ranging from agriculture to transportation, to identify decisions being made in response to climate change. Advancing the Science of Climate Change calls for a single federal entity or program to coordinate a national, multidisciplinary research effort aimed at improving both understanding and responses to climate change. Seven cross-cutting research themes are identified to support this scientific enterprise. In addition, leaders of federal climate research should redouble efforts to deploy a comprehensive climate observing system, improve climate models and other analytical tools, invest in human capital, and improve linkages between research and decisions by forming partnerships with action-oriented programs.

This volume proposes to provide a concise, simple, well-illustrated book that explains past sea rise events, what scientists know about the present and future sea level rise, the consequences of rise, and how Floridians might prepare.

The Intergovernmental Panel on Climate Change (IPCC) is the leading international body for assessing the science related to climate change. It provides policymakers with regular assessments of the scientific basis of human-induced climate change, its impacts and future risks, and options for adaptation and mitigation. This IPCC Special Report on the Ocean and Cryosphere in a Changing Climate is the most comprehensive and up-to-date assessment of the observed and projected changes to the ocean and cryosphere and their associated impacts and risks, with a focus on resilience, risk management response options, and adaptation measures, considering both their potential and limitations. It brings together knowledge on physical and biogeochemical changes, the interplay with ecosystem changes, and the implications for human communities. It serves policymakers, decision makers, stakeholders, and all interested parties with unbiased, up-to-date, policy-relevant information. This title is also available as Open Access on Cambridge Core.

A must-read for Gulf Coast scientists, naturalists, and residents . . . From Florida to Mexico and along the shores of Cuba, the coasts of the Gulf of Mexico are vulnerable to sea-level rise because of their fragile and low-lying shorelines and adjacent coastal environments. In addition to wetlands, river deltas, beaches, and barrier islands, millions of people who live and work along the Gulf coast are susceptible to the affects of both intense storms in the short term and a gradual rise in sea level over the longer term. While global warming headlines any current discussion of this topic and is certainly a major factor in sea-level change, it is not the only factor. Earthquakes and other crustal shifts, the El Niño/La Niña phenomena, river impoundment and sedimentation, tides, and weather can all affect local, regional, and global sea levels. In Sea-Level Change in the Gulf of Mexico, Richard A. Davis Jr. looks at the various causes and effects of rising and falling sea levels in the Gulf of Mexico, beginning with the Gulf’s geological birth over 100 million years ago, and focusing on the last 20,000 years, when global sea levels began rising as the glaciers of the last major ice age melted. Davis reviews the current situation, especially regarding beach erosion and loss of wetlands, and offers a preview of the future, when the Gulf Coast will change markedly as the twenty-first century progresses. Amply illustrated and written in a clear, straightforward style, Sea-Level Change in the Gulf of Mexico is a valuable resource for anyone who cares deeply about understanding the past, present, and future of life along the coast of the Gulf of Mexico.

This book contains updated, reviewed versions of some selected papers on OC Sea-Level Changes and their EffectsOCO presented at the International Ocean and Atmosphere Pacific Conference (OAP 95), held in Adelaide, South Australia, 23OCo27 October 1995. In addition several reviewed articles on important topics not covered by the papers presented at OAP 95 were invited. The articles in this volume will find an audience among coastal developers, marine biologists and environmentalists. They cover a range of topics including the efforts of long-term sea-level rise on coastal flows and its impact on mangrove communities, the determination of long-term sea-level change relative to the vertical motion of the land, to the numerical modelling of short term sea-level changes due to tides, tsunamis and the weather.
