This report presents the results of EcoAdapt’s efforts to survey adaptation action in marine fisheries management by examining the major climate impacts on marine and coastal fisheries in the United States, assessing related challenges to fisheries management, and presenting examples of actions taken to decrease vulnerability and/or increase resilience. First, we provide a summary of climate change impacts and secondary effects on fisheries, focusing on changes in air and water temperatures, precipitation patterns, storms, ocean circulation, sea level rise, and water chemistry.
While previous research has documented marine fish and invertebrates shifting poleward in response to warming climates, less is known about the response of fisheries to these changes. By examining fisheries in the northeastern United States over the last four decades of warming temperatures, we show that northward shifts in species distributions were matched by corresponding northward shifts in fisheries. The proportion of warm-water species caught in most states also increased through time.
This integrated research project, which ran from 2007-2008, was initiated to better understand the implications of projected climate change impacts and adaptation responses on southern Ontario’s fish, fisheries, and water resources. Climate change will have predominantly negative effects on species and habitats, and resulting economic effects are expected to be devastating to the region. In addition, changes in temperature and precipitation patterns will require alterations to water resources planning and management.
The Working Group II contribution to the AR5 (WGII AR5) has 30 chapters, a Technical Summary, and a Summary for Policymakers. The WGII AR5 considers the vulnerability and exposure of human and natural systems, the observed impacts and future risks of climate change, and the potential for and limits to adaptation. The chapters of the report assess risks and opportunities for societies, economies, and ecosystems around the world.
The impact of climate change on cold-water ecosystems—and the cold-adapted native salmonids present in these systems—is the subject of a substantial body of research.. Recently, scientists have developed a number of datasets and analyses that provide insight into projections of climate change e ects on native salmonid populations in the northern U.S. Rockies region.
The Western Regional Action Plan outlines present and prioritizes future efforts to increase the production, delivery, and use of the climate-related information needed to help fulfill NOAA Fisheries’ mission and implement the NOAA Fisheries’ Climate Science Strategy (NCSS) in the CCLME over the next three to five years.
