A strong, but fading El Niño contributed to temperature and rainfall extremes, including record-setting drought. Experts and coastal managers should factor in locally and regionally specific information on climatic, physical, ecological, and biological processes and on the culture and economy of coastal communities. It builds on the 2014 National Climate Assessment and reviews and synthesizes key contributions to the published literature. This document also describes EPA’s approach and criteria for selecting indicators for the report. Gnatz, Mary Hayden, Maria Eugenia Ibarraran Viniegra, Elena Jiménez Cisneros, Michael D. This report documents climate change related impacts and responses for various sectors and regions, with the goal of better informing public and private decision-making at all levels. From a combined survey of physical and chemical water properties and biological sampling along the Washington–Oregon–California coast in August 2011, the authors show that large portions of the shelf waters are corrosive to pteropods in the natural environment. Chapter 4 presents analyses of how changes in ocean acidification may affect the economics of marine fisheries in regions of the Arctic and on food security and cultural issues for coastal Arctic indigenous communities.

Acknowledging the rising demand for data that can be used to characterize how climate change affects health, this report assesses recent analyses that quantify observed and projected health impacts. Meyer, Amrutasri Nori-Sarma, Landy Sánchez Peña, Catherine Ngo, Greg Oulahen, Diana Pape, Ana Peña del Valle, Roger Pulwarty, Ashlinn Quinn, Daniel Runfola, Fabiola S. Udall, Fiona Warren, Kate Weinberger, and Tom Wilbanks (contributing authors). Global Change Research Program (USGCRP) with the results of research and observations from across the U. and around the world, including reports from the U. The report draws from a large body of scientific, peer-reviewed research, as well as a number of other publicly available sources. They show a strong positive correlation between the proportion of pteropod individuals with severe shell dissolution damage and the percentage of undersaturated water in the top 100 m with respect to aragonite. Chapter 5 presents an overall summary of the major findings and gaps in knowledge on Arctic Ocean acidification. Arctic Monitoring and Assessment Programme (AMAP), Oslo, Norway.The report assesses needs, options, opportunities, constraints, resilience, limits, and other aspects associated with adaptation. The scientists said that their study was the first to prove the link between rising ocean acidification and the potential decrease in planet-cooling sulfur dioxide aerosols. The site was designed to allow local governments, small business owners and natural resource managers to plan for a future of warming-fueled extreme weather.
It provides a detailed update on global climate indicators, notable weather events, and other data collected by environmental monitoring stations and instruments located on land, water, ice, and in space." "An overview of findings is presented in the Abstract and Introduction. A national ocean acidification data management and information exchange program will ensure that ocean and Great Lakes acidification information reaches scientists, decision makers, and the public in a timely manner. Link: type: Report Description: Excess carbon dioxide in the atmosphere, in addition to contributing to climate change, is absorbed by the ocean, making sea water more acidic and leading to a suite of changes in ocean chemistry.Chapter 2 features global-scale climate variables; Chapter 3 highlights the global oceans; and Chapter 4 includes tropical climate phenomena including tropical cyclones. Preliminary evidence suggests ocean acidification will have negative effects on corals, shellfish, and other marine life, with wide-ranging consequences for ecosystems, fisheries, and tourism.The Arctic and Antarctic respond differently through time and are reported in separate chapters (5 and 6, respectively). This report, requested by Congress, reviews the current state of knowledge and identifies gaps in understanding, and provides scientific advice to help guide the national ocean acidification research program. Committee on the Development of an Integrated Science Strategy for Ocean Acidification Monitoring, Research, and Impacts Assessment; National Research Council. record_id=12904# Resource type: Online article Description: In a Swedish fford, European researchers are conducting an ambitious experiment aimed at better understanding how ocean acidification will affect marine life.Chapter 2 features global-scale climate variables; Chapter 3 highlights the global oceans; and Chapter 4 covers tropical climate phenomena including tropical cyclones. A key characteristic of abrupt climate changes is that they can unfold faster than expected, planned for, or budgeted for, forcing a reactive, rather than proactive mode of behavior. Committee on Understanding and Monitoring Abrupt Climate Change and Its Impacts; Board on Atmospheric Sciences and Climate; Division on Earth and Life Studies; National Research Council. The chapter also examines both abrupt climate changes in the physical climate system itself and abrupt climate impacts in physical, biological, or human systems that are triggered by a steadily changing climate. The approach can be used by local and state planners to objectively evaluate different policy options for effectiveness and cost/benefit.The Arctic and Antarctic respond differently through time and are reported in separate chapters (5 and 6, respectively). : This report covers the physical science basis of climate change, including: analysis of greenhouse gas emissions and their atmospheric concentrations, as well as the global carbon cycle; coverage of the atmosphere, the land-surface, the oceans, and all of the major components of the cryosphere (land-ice, glaciers, ice shelves, sea-ice and permafrost); paleoclimate, extreme events, sea level, future projections, abrupt climate change and tipping points; and explanations of some of the common misconceptions surrounding climate change science. In this study, CERI is applied to RI two communities; Charlestown representing a typical coastal barrier system directly exposed to ocean waves and high erosion rates, with predominantly low density single family residences and Warwick located within Narragansett Bay, with more limited wave exposure, lower erosion rates, and higher residential housing density.

Richardson, David Schoeman, Sergio Signorini, William Skirving, Dáithí Stone, William Sydeman, Rui Zhang, Ruben van Hooidonk (contributing authors). : This report provides an updated look at the issue of abrupt climate change and its potential impacts; considering not only abrupt changes to the climate system itself, but also abrupt impacts and tipping points that can be triggered by gradual changes in climate. CERI has been designed as an on line Geographic Information System (GIS) based tool, and hence is fully compatible with current flooding maps, including those from FEMA.
