Regional adaptation fora (RAFs) are regional climate change adaptation conferences associated with the National Adaptation Forum. There are six RAFs: the California Adaptation Forum, the Carolinas Climate Resilience Conference, the Great Lakes Adaptation Forum, Local Solutions: Eastern Climate Preparedness Conference, the Southeast Florida Climate Change Compact Summit, and the Southwest Adaptation Forum. This report presents analysis and information drawn from the 2018 RAFs to gain insight about the state of the field, assess opportunities for the field to leverage the RAFs to accelerate dissemination and uptake of promoting promising adaptation practices across regions, and determine how the American Society of Adaptation Professionals can best support the RAFs going forward. The top finding is that RAFs are moving the needle for adaptation professionals and the field. The report serves as a testament to the need for, and value of, regional adaptation fora and encourages increased investment in these events and greater coordination between them.

The Global Change Research Act of 1990 mandates that the U.S. Global Change Research Program deliver a report to Congress and the President no less than every four years that “1) integrates, evaluates, and interprets the findings of the Program…; 2) analyzes the effects of global change on the natural environment, agriculture, energy production and use, land and water resources, transportation, human health and welfare, human social systems, and biological diversity; and 3) analyzes current trends in global change, both human-induced and natural, and projects major trends for the subsequent 25 to 100 years.” The Fourth National Climate Assessment (NCA4) fulfills that mandate in two volumes. This report, Volume II, draws on the foundational science described in Volume I, the Climate Science Special Report. Volume II focuses on the human welfare, societal, and environmental elements of climate change and variability for 10 regions and 18 national topics, with particular attention paid to observed and projected risks, impacts, consideration of risk reduction, and implications under different mitigation pathways. Where possible, NCA4 Volume II provides examples of actions underway in communities across the United States to reduce the risks associated with climate change, increase resilience, and improve livelihoods. This assessment was written to help inform decision makers, utility and natural resource managers, public health officials, emergency planners, and other stakeholders by providing a thorough examination of the effects of climate change on the United States.

Shorelines with high boat wake and wave energy face especially rapid erosion and habitat loss. A new living shoreline design from researchers at the University of Florida and the Guana Tolomato Matanzas Reserve that uses gabion-breaks has proven successful in high-energy environments. The gabion-break design uses two lines of defense to reduce erosion along the marsh edge—porous wooden breakwalls placed in front of structures that will foster oyster growth. This manual for restoration practitioners describes a collaborative research project that tested gabion-breaks along the Atlantic Intracoastal Waterway in northeast Florida. It discusses the project’s results and details the steps to use gabion-breaks, including planning, design, maintenance, monitoring, and costs.

This analysis examines what's at risk for U.S. coastal real estate from sea level rise. Millions of Americans living in coastal communities will face more frequent and disruptive high-tide flooding; as this flooding increases, it will reach a threshold where normal routines become impossible and coastal residents, communities, and businesses are forced to make difficult, often costly choices. For this analysis, that threshold is defined as flooding that occurs 26 times per year (on average, once every other week) or more, a level of disruption referred to as chronic inundation. The results identify the number of residential and commercial properties at risk of chronic inundation—and the total current property value, estimated population, and property tax base affected—for the entire coastline of the lower 48 states.

As incomes rise and populations grow, especially in the world’s hotter regions, the use of air conditioners is becoming increasingly common. In fact, the use of air conditioners and electric fans already accounts for about a fifth of the total electricity in buildings around the world–or 10 percent of all global electricity consumption. Over the next three decades, the use of ACs is set to soar, becoming one of the top drivers of global electricity demand. This new analysis by the International Energy Agency shows how new standards can help the world avoid facing such a “cold crunch” by helping improve efficiency while also staying cool.

The goal of this concerted effort is to help Thurston County (Washington) and the broader South Puget Sound region prepare for and adjust to climate change. The Thurston Regional Planning Council crafted this document with a $250,000 National Estuary Program grant from the U.S. Environmental Protection Agency and significant in-kind support from the community. Partners included representatives from tribes, municipalities, universities, nonprofits, businesses, and other entities within the project area: three geographically diverse watersheds (Nisqually, Deschutes, and Kennedy-Goldsborough) within Thurston County that drain into Puget Sound. The watersheds encompass beaches, rivers, lakes, wetlands, highlands, forests, farms, ranches, cities, towns, and tribal reservations. It is the Council's hope that other communities throughout the Puget Sound region, state, and nation will replicate this project’s science-based assessments, innovative public-engagement efforts (including development of a resilience game), collaborative planning processes, economic analyses, and comprehensive actions.
