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.
This report is the first major product of the current Canadian national assessment, which launched in 2017 and intends to publish a series of authoritative reports between 2018 and 2021. This assessment focuses on answering the questions: how has Canada’s climate changed to date, why, and what changes are projected for the future? This initial report provides a climate science foundation for the other national assessment products. Its objectives are to assess current knowledge about how Canada’s climate is changing and why, and what changes are projected for the future, to help inform mitigation and adaptation decision making and to help raise public awareness and understanding of Canada’s changing climate. The CCCR is written for a broad range of professionals who are familiar with the topic of climate change but who may not have expertise in the physical sciences.

The report also provides recommendations to the Gulf Research Program to build and measure resilience in the Gulf of Mexico region.
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.
