America S Most Vulnerable Coastal Communities

"Sea level is rising, and yet Americans continue to develop beaches with little regard. In this volume, a group of coastal geologists discusses the startling saga of ten U.S. East and Gulf Coast shoreline communities (plus Puerto Rico and some western Europe strands) and the problems created by their inevitable interaction with natural processes in this highly dynamic geologic environment. The authors discuss the geologic context of the hazards of each site as the history of societal responses and their environmental impacts. Response to the natural coastal processes that threaten lives and buildings is carried out in a context of local, state and national politics with fixed short-term engineering solutions (beach replenishment, seawalls) generally favored over longer-term approaches (moving back, prohibition of seawalls). This essential GSA Special Paper foreshadows the impending rise of sea level and the myriad of shoreline responses and political controversies it will provoke."--Publisher's description.

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.

Tens of millions of Americans are at risk from sea level rise, increased tidal flooding, and intensifying storms. A Blueprint for Coastal Adaptation identifies a bold new research and policy agenda and provides implementable options for coastal communities responding to these threats. In this book, coastal adaptation experts present a range of climate adaptation policies that could protect coastal communities against increasing risk, including concrete financing recommendations. Coastal adaptation will not be easy, but it is achievable using varied approaches. A Blueprint for Coastal Adaptation will inspire innovative and cross-disciplinary thinking about coastal policy at the state and local level while providing actionable, realistic policy and planning options for adaptation professionals and policymakers.

Climate change is predicted to increase the frequency and magnitude of coastal storms around the globe, and the anticipated rise of sea levels will have enormous impact on fragile and vulnerable coastal regions. In the U.S., more than 50% of the population inhabits coastal areas. In Planning for Coastal Resilience, Tim Beatley argues that, in the face of such threats, all future coastal planning and management must reflect a commitment to the concept of resilience. In this timely book, he writes that coastal resilience must become the primary design and planning principle to guide all future development and all future infrastructure decisions. Resilience, Beatley explains, is a profoundly new way of viewing coastal infrastructure—an approach that values smaller, decentralized kinds of energy, water, and transport more suited to the serious physical conditions coastal communities will likely face. Implicit in the notion is an emphasis on taking steps to build adaptive capacity, to be ready ahead of a crisis or disaster. It is anticipatory, conscious, and intentional in its outlook. After defining and explaining coastal resilience, Beatley focuses on what it means in practice. Resilience goes beyond reactive steps to prevent or handle a disaster. It takes a holistic approach to what makes a community resilient, including such factors as social capital and sense of place. Beatley provides case studies of five U.S. coastal communities, and “resilience profiles” of six North American communities, to suggest best practices and to propose guidelines for increasing resilience in threatened communities.

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.

Hurricane- and coastal-storm-related losses have increased substantially during the past century, largely due to increases in population and development in the most susceptible coastal areas. Climate change poses additional threats to coastal communities from sea level rise and possible increases in strength of the largest hurricanes. Several large cities in the United States have extensive assets at risk to coastal storms, along with countless smaller cities and developed areas. The devastation from Superstorm Sandy has heightened the nation's awareness of these vulnerabilities. What can we do to better prepare for and respond to the increasing risks of loss? Reducing Coastal Risk on the East and Gulf Coasts reviews the coastal risk-reduction strategies and levels of protection that have been used along the United States East and Gulf Coasts to reduce the impacts of coastal flooding associated with storm surges. This report evaluates their effectiveness in terms of economic return, protection of life safety, and minimization of environmental effects. According to this report, the vast majority of the funding for coastal risk-related issues is provided only after a disaster occurs. This report calls for the development of a national vision for coastal risk management that includes a long-term view, regional solutions, and recognition of the full array of economic, social, environmental, and life-safety benefits that come from risk reduction efforts. To support this vision, Reducing Coastal Risk states that a national coastal risk assessment is needed to identify those areas with the greatest risks that are high priorities for risk reduction efforts. The report discusses the implications of expanding the extent and levels of coastal storm surge protection in terms of operation and maintenance costs and the availability of resources. Reducing Coastal Risk recommends that benefit-cost analysis, constrained by acceptable risk criteria and other important environmental and social factors, be used as a framework for evaluating national investments in coastal risk reduction. The recommendations of this report will assist engineers, planners and policy makers at national, regional, state, and local levels to move from a nation that is primarily reactive to coastal disasters to one that invests wisely in coastal risk reduction and builds resilience among coastal communities.
