The Beloved Community is a vision for our future where all people share equally in the wealth and bounty of the earth, where we protect its abundance, diversity, and beauty for future generations. In this vision of liberation, racism, exploitation, and domination are replaced by democracy, cooperation, interdependence, and love. To get there, we pursue transformative, systems-change solutions. What do we mean by this? The root causes of the problems our communities face—like climate change, racism, and economic inequality—are all deeply connected. Since the problems are connected, so are the solutions. The purpose of this toolkit is to put us on the path toward achieving this vision. Through the context of building equity and resilience into climate adaptation planning, we introduce strategies to transform our communities and, by extension, society. Our ultimate goal is to create lasting and systemic change. At the same time, we recognize the urgency of the issues our communities face and the need to take action now. That is why we pursue change at every scale—from policy changes to community-based projects—to institute the transformative change we need to uphold our vision of the beloved community.

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.

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.

From Mayor Mitchell J. Landrieu's Introduction: As we marked the 10th anniversary of Hurricane Katrina in 2015, we launched the world’s first comprehensive city resilience strategy, Resilient New Orleans, combining local expertise with global best practices to confront our most urgent threats, adapt our city to our changing natural environment, invest in equity, create flexible and reliable systems, and prepare for future shocks. 

It is not enough to plan for how we will adapt to climate change. We must end our contribution to it. As the world committed to action in Paris in 2015, so too did we. I signed the Global Covenant of Mayors on Climate & Energy, adding New Orleans to the team of more than 7,400 cities in 119 countries worldwide committed to taking climate action.

In the aftermath of Tropical Storms Irene and Sandy, the population centers of Greater New Haven and Bridgeport recognized significant exposure and vulnerability to their infrastructure, environment, and socioeconomic assets from extreme weather events and a changing climate. To counteract immediate and longer-term risks and broaden dialogue on community resilience building, the Southern Connecticut Regional Framework for Coastal Resilience project was launched. The overarching goal of this project was prioritizing actions and strengthening partnerships by providing proactive risk assessment, community engagement, conceptual design of on-the-ground projects, and this Final Report. The principal purpose of the project was to advance a Regional Resilience Framework—built on projects and partnerships—needed to help improve resilience for over 591,000 residents that represent over 30 percent of Connecticut’s coast. A core goal of this project was to strengthen the resilience of existing and future ecosystems, including a diverse suite of services and co-benefits, alongside existing and future development activities within a population center critical to the state of Connecticut’s future.
