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.

This report reviews the evidence to establish which sources of sea-level rise projections are credible for the Pacific islands region. It examines the strengths, weaknesses, and uncertainties associated with various sources of information on sea-level rise in the Pacific. It aims to provide advisory standards for the planning, testing, and design of Asian Development Bank projects in the area.

These proceedings include papers on Sea Level Rise in Australia and the Pacific, The Effects of Sea Level Changes on Tropical Island Climate Shifts in the Pacific, as well as other related topics.

Prepared for the 2013 National Climate Assessment and a landmark study in terms of its breadth and depth of coverage, Climate Change and the Pacific Islands was developed by the Pacific Islands Regional Climate Assessment, a collaborative effort engaging federal, state, and local government agencies, non-government organizations, academician, businesses, and community groups to inform and prioritize their activities in the face of a changing climate. The book assesses the state of knowledge about climate change indicators, impacts, and adaptive capacity of the Hawaiian archipelago and the US-Affiliated Pacific Islands. The book provides the basis for understanding the key observations and impacts from climate change in the region, including the rise in surface air and sea-surface temperatures, along with sea levels, and the changes in ocean chemistry, rainfall amount and distribution, weather extremes, and widespread ecosystem changes. Rich in science and case studies, it examines the latest climate change impacts, scenarios, vulnerabilities, and adaptive capacity and offers decision makers and stakeholders a substantial basis from which to make informed choices that will affect the well-being of the region’s inhabitants in the decades to come.

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.

This edited volume addresses the impacts of climate change on Pacific islands, and presents databases and indexes for assessing and adapting to island vulnerabilities. By analyzing susceptibility variables, developing comprehensive vulnerability indexes, and applying GIS techniques, the book's authors demonstrate the particular issues presented by climate change in the islands of the Pacific region, and how these issues may be managed to preserve and improve biodiversity and human livelihoods. The book first introduces the issues specific to island communities, such as high emissions impacts, and discusses the importance of the lithological traits of Pacific islands and how these physical factors relate to climate change impacts. From here, the book aims to analyze the various vulnerabilities of different island sectors, and to formulate a susceptibility index from these variables to be used by government and planning agencies for relief prioritization. Such variables include tropical cyclones, built infrastructures, proximity to coastal areas, agriculture, fisheries and marine resources, groundwater availability, biodiversity, and economic impacts on industries such as tourism. Through the categorization and indexing of these variables, human and physical adaptation measures are proposed, and support solutions are offered to aid the inhabitants of affected island countries. This book is intended for policy makers, academics, and climate change researchers, particularly those dealing with climate change impacts on small islands.
