Climate Change And Coastal Ecosystems

Produced by a Leading Aquatic ScientistA narrative account of how estuaries around the world are being altered by human forces and human-induced global climate changes, Climate Change and Coastal Ecosystems: Long-Term Effects of Climate and Nutrient Loading on Trophic Organization chronicles a more than 40-year-old research effort conducted by Dr.

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.

Coastal marine systems are among the most ecologically and socio-economically vital on the planet. It is now widely acknowledged that coastal and marine environments are experiencing enhanced changes as a result of natural and anthropogenic induced causes. Physical impacts of climate change, such as sea-level rise and extreme inundation events, pose a considerable threat to coastal settlements and the coastal ecosystems that provision and support them. Increases in concentrations of greenhouse gases projected for the 21st century are expected to lead to increased mean global air and ocean temperatures. Anthropogenically induced global climate change has profound implications for marine ecosystems and the economic and social systems that depend upon them. The relationship between temperature and individual performance is reasonably well understood, and much climate-related research has focused on potential shifts in distribution and abundance driven directly by temperature. Climate Change and Coastal Ecosystems covers the pioneer of the coastal and marine resources sector review of potential impacts on shorelines, estuaries, coastal wetlands, coral reefs, and ocean margin ecosystems. It reviews recent advances in our understanding of the physical and chemical nature of climate change in coastal oceans. Also, it examines the likely ecological responses to climate change as well as the proximate effects of environmental change, including impacts on individuals, populations and communities are addressed. The broader ecological responses that will emerge from these proximal impacts; emergent responses include alterations in biologically and socio-economically important patterns and processes ranging from primary productivity to biogeography to evolution are considered. This book considers major knowledge gaps and research needs in order to: assess the risk climate change poses to coastal settlements, coastal ecosystems and the interplay between the two; develop appropriate adaptation strategies for coastal settlements and ecosystems; and ascertain how land-based activities and adaptation strategies will influence the adaptive capacity of coastal ecosystems. This book will appeal to students, practitioners, as well as a beneficial guide for researchers working on riverine, estuarine, and coastal marine systems.

Explores how two coastal ecosystems are responding to the pressures of human expansion The Northern Adriatic Sea, a continental shelf ecosystem in the Northeast Mediterranean Sea, and the Chesapeake Bay, a major estuary of the mid-Atlantic coast of the United States, are semi-enclosed, river-dominated ecosystems with urbanized watersheds that support extensive industrial agriculture. Coastal Ecosystems in Transition: A Comparative Analysis of the Northern Adriatic and Chesapeake Bay presents an update of a study published two decades ago. Revisiting these two ecosystems provides an opportunity to assess changing anthropogenic pressures in the context of global climate change. The new insights can be used to inform ecosystem-based approaches to sustainable development of coastal environments. Volume highlights include: Effects of nutrient enrichment and climate-driven changes on critical coastal habitats Patterns of stratification and circulation Food web dynamics from phytoplankton to fish Nutrient cycling, water quality, and harmful algal events Causes and consequences of interannual variability The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.

Each year, floods cause an enormous amount of global economic and social damage, impacting transportation systems, water supplies, agriculture, and health. Response management to catastrophic floods require increased measures involving integrated planning, adaptation, and recovery strategies in order to protect against human loss. Decision Support Methods for Assessing Flood Risk and Vulnerability is a pivotal reference source that provides vital research on the application of effective models and tools focused on the diagnosis of vulnerability to flooding risks and evaluates and measures the impact of floods on socio-economic wellbeing. While highlighting topics such as hydrological events, soil erosion, and flood vulnerability, this publication explores methods of identifying appropriate adaptation strategies. This book is ideally designed for researchers, students, academicians, policymakers, government officials, and technology developers seeking current empirical research findings to be used to improve the overall understanding of the flood phenomenon.

This volume incorporates theoretical and practical knowledge through case studies and reviews to serve as a baseline of information for coastal ecosystem research, and discusses the impacts of pollution, industrialisation, agriculture and climate change on coastal ecosystem biogeochemistry and biodiversity. The case studies address the role of coastal ecosystems as a carbon sink which is getting impacted by anthropogenic disturbances. Through this analysis, the book covers various strategies for the conservation and management of coastal ecosystems, considering their unique ecological and biogeochemical attributes and region-specific threats and impacts. The book will be of interest to a wide range of readers including students, researchers and professionals in coastal ecosystem science, coastal pollution, climate change adaptation, biodiversity conservation and environmental management.

This book describes critical environmental issues that face coastal ocean and Great Lakes areas, including eutrophication, habitat modification, hydrologic and hydrodynamic disruption, exploitation of resources, toxic effects on ecosystems and humans, introduction of nonindigenous species, global climate change and variability, and shoreline erosion and hazardous storms. These issues can be approached through science activities (including research, monitoring, and modeling) discussed in this book and through coordination among federal agencies.
