For the six states of the U.S. Southwest (Arizona, California, Colorado, Nevada, New Mexico, and Utah)i , January 2020 through August 2021 have been exceptional in the instrumental climate record since 1895, with the lowest total precipitation and the third-highest daily average temperatures recorded, which together imposed an unyielding, unprecedented, and costly drought. This exceptional drought punctuates a two-decade period of persistently warm and dry conditions throughout the region.
This report presents key findings from evaluative research investigating the Pacific Islands Climate Change Cooperative's (PICCC) achievements in the Hawaiian Islands between 2009 and 2018. Based on interviews and a survey, the report describes the foundational conditions from which the PICCC set out to establish a landscape conservation framework, the challenges it faced, its goals and achievements, and transferable lessons from the experience for any conservation community working with limited resources across large expanses of land and ocean.
This Guide is written for practitioners already using or wanting to use future climate information in their work, but who are not familiar with the underlying assumptions and choices surrounding climate data. Here, we introduce the climate model scenarios that are used to “drive” climate models forward in time. These scenarios are a combination of socioeconomic and climate forcing pathways. We summarize differences between these scenarios for the Great Lakes region to show users how their choice of model scenario affects future temperature and precipitation projections.
This report provides step-by-step guidance and lessons learned on how to effectively engage with community members to understand climate impacts and to develop more equitable climate resilience strategies. Community-based organizations have repeatedly emphasized that to equitably and successfully carry out climate resilience solutions, it’s imperative to directly engage with community members to deeply understand how these threats directly impact them. Likewise, to formulate solutions that are equitable and truly work—and to get utilities and city officials to prioritize equitable investments in under-invested areas—organizations must directly engage with members of the community when identifying solutions. The toolkit provides real-world case studies, a project planning and facilitation guide, and extensive lists of references and resources.
This report aims to build the capacity of organizations to serve as catalysts in supporting members of their communities stepping into leadership roles, as well as engaging them meaningfully in defining the scope of local climate change risks and impacts and formulating and implementing equitable solutions alongside key partners. This guide was developed using qualitative data collected through a series of interviews with experts from around the country who are designing, managing, and implementing community-based leadership development programs. Although not all of these programs directly address climate change and environmental justice, this collection of diverse programming illustrates the broad ways in which communities address leadership development and grassroots engagement in local decision making. This tool provides a comprehensive picture of training and capacity-building theory and practice, and showcases programs that are diverse in content, audience, geography, outcome, and practice.
This report brings together researchers, clinicians, public health experts, climate scientists, tribal experts, and community leaders from throughout Montana to focus on ways climate change impacts the health of Montanans, both now and in the future. The assessment highlights the most likely climate impacts—heat, wildfires, drought, and flood—on physical and mental health, and recommends important steps that communities, health professionals, and individuals can take to lessen those impacts.
Hotter weather, stronger typhoons, coral reef death, and physical and mental health risks are among the major challenges detailed in this report on climate change in the Commonwealth of the Northern Mariana Islands (CNMI).

The 2020 State Climate Strategy informs policymaking on how Nevada will achieve the ambitious targets established by SB 254 and provides an integrated framework for evaluating climate policies that make sense for Nevada. This will optimize effectiveness of each given policy and therefore maximize the benefits for all Nevadans. By taking a smart, strategic approach to addressing climate change in Nevada, the state can fully capture the economic benefits of clean technologies and lead the way in the neighboring Western states.
As sea levels rise along the Northeastern U.S., coastal forest ecosystems are being impacted. To better enable climate-smart decision-making, the U.S. Department of Agriculture Northeast Climate Hub engaged researchers at Rutgers University to conduct a synthesis of the current state of knowledge concerning how Northeastern U.S. coastal forests, specifically those in mid-Atlantic and southern New England states (VA, MD, DE, NJ, NY, CT, and MA), are responding to impacts from climate change. Drawing upon the scientific literature, expert interviews, and a January 2020 convening of scientists and land managers at the U.S. National Agricultural Library, Beltsville, Maryland, this synthesis identifies key knowledge gaps as well as potential management approaches.
An intensified pattern of wildfire is emerging in Alaska as rapidly increasing temperatures and longer growing seasons alter the state's environment. This publication aims to convey the rapidly changing patterns of wildfire in Alaska by looking into the phases of fire. Patterns emerging in the 21st century are the primary focus, with earlier histories of management, climate, and fire being drawn upon for context.
This report presents recommendations for how state governments can develop climate-resilience financial systems that help local communities invest in protecting residents, businesses, public infrastructure, private property, and natural resources from climate-driven stresses and shocks. To help states consider and act on the recommendations, a State Climate Resilience Action Checklist (page 50) identifies the essential actions that states need to take to build a comprehensive approach to resilience, including a financial system. The report also offers an Inventory of Climate Resilience Actions.

The report also includes chapters on sea level rise, trends involving interactions of multiple aspects of the climate system (including inland flooding, wildfire, forest ecosystem changes, urban heat island effects, and air pollution), and findings relevant to engineering design standards.
Each region of the United States experiences climate change and its impacts on health differently, due to the regions’ location-specific climate exposures and unique societal and demographic characteristics. This document describes the various health impacts climate change will have on different regions of the United States as outlined in the Fourth National Climate Assessment (NCA4), actions taken by the CDC Climate and Health Program’s health department partners to prepare for and respond to climate change in their communities, and relevant tools and resources.
While all people living in the United States are affected by climate change, some communities and some populations are more vulnerable to changing climate conditions than others. This final report from a NOAA-funded project in New Jersey highlights current evidence regarding impacts of changing climate-related coastal hazards on socially vulnerable populations, identify opportunities to address needs of socially vulnerable populations as part of coastal community climate resilience planning, and outlines possible options for coastal management policy that may enhance efforts to address needs of socially vulnerable populations as part of coastal community resilience efforts.
Planning for climate change resiliency is an increasingly pressing requirement for communities throughout the world and the Delaware Valley Regional Planning Commission (DVRPC) region. In order to help local officials, non-profits, and communities with this process, numerous planning tools have been developed by a wide range of public and private agencies. Accordingly, the purpose of this paper is to explain, organize, and prioritize the tools that currently exist in order to select ones that are broadly accessible to a wide range of organizations, applicable across a range of sectors, and not overly redundant. During this selection process, a list of over 60 tools was winnowed down to a final toolkit of 18 that are particularly useful at any stage in the resiliency planning process and can be used for communities throughout the DVRPC region.
This report and the accompanying community spotlights provide an overview of climate change science, reasons why action is needed, how science supports decision making and planning, ways to adapt to climate change and limit the severity of its effects, and how such efforts can help build resiliency. The report illustrates the ways in which science can help individuals, communities, businesses, and government agencies make informed decisions. By working together to identify solutions and bring about positive change, we can reduce the risks faced by current and future generations.
The Fish and Wildlife Relevancy Roadmap is a practical guide that state and provincial fish and wildlife conservation agencies can use to overcome barriers to broader relevance, public engagement, and support. The roadmap is not prescriptive and provides multiple pathways to respond to the diverse social, economic, demographic, political, and environmental changes that states and provinces face. The Roadmap was developed by a team of over 60 leaders from state, federal, provincial, and private conservation organizations and others with an interest in conservation.
Alaska has recently experienced profound environmental change related to extreme weather events and deviations from the historical climate. Sustained warmth, sea ice loss, coastal flooding, river flooding, and major ecosystem changes have impacted the daily lives of Alaskans around the state. The International Arctic Research Center and the University of Alaska Fairbanks have documented these changes, and are providing individuals, Alaska businesses, communities, government, and others with the resources they need to better assess impacts and develop adaptation strategies.
Communities in Hawai'i are highly vulnerable to natural disasters such as hurricanes, tsunamis, floods, seasonal high waves, earthquakes, volcanic eruptions, lava flows, and sea level rise. Since a changing climate is expected to worsen the effects of these natural hazards, planners and communities must work together to prepare for long term disastor recovery. The study developed statewide guidance documents and tools to improve community resilience to coastal hazards and sea level rise, thereby encouraging communities to focus on recovery practices before a disaster hits.
The Central Council of the Tlingit and Haida Indian Tribes of Alaska (Tlingit & Haida) is a federally recognized Indian Tribe that serves 20 villages and communities stretching over 43,000 square miles within the Alaska Panhandle. The Tlingit and Haida membership is among the largest, most isolated, and most geographically dispersed of Native or Tribal populations nationwide. The region encompasses a 525-mile strip of coastline and interior waterways, bordered by Canada on the north, south, and east, with the Gulf of Alaska on the west.
The Central Council recognizes that wild salmon, berries, clams, herring, halibut, yellow cedar and other species important for subsistence, cash and culture are at risk. In response, they have released a 53-page climate change adaptation plan. The document is a roadmap for prioritizing, monitoring, and responding to threats stemming from warming air and ocean temperatures, caused by increasing levels of greenhouse gases trapped in the atmosphere.

The guidance provided by this report is designed to help all communities create disaster debris management plans. It assists communities in planning for natural disaster debris before disasters—such as hurricanes, earthquakes, tornadoes, volcanoes, floods, wildfires, and winter storms—occur by providing useful, relevant information intended to increase community preparedness and resiliency. The report includes recommended components of a debris management plan, suggested management options for various natural disaster debris streams, a collection of case studies that highlights how several communities prepared for and managed debris generated by recent natural disasters, resources to consult in planning for natural disasters, and the EPA’s recommended pre-incident planning process to help prepare communities for effective disaster debris management.
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.
Flooding is the natural hazard with the greatest economic and social impact in the United States, and these impacts are becoming more severe over time. This report contributes to existing knowledge on urban flooding by examining real-world examples in specific metropolitan areas: Baltimore, Houston, Chicago, and Phoenix. The report identifies commonalities and variances among the case study metropolitan areas in terms of causes, adverse impacts, unexpected problems in recovery, or effective mitigation strategies, as well as key themes of urban flooding. It also relates, as appropriate, causes and actions of urban flooding to existing federal resources or policies.

This report summarizes the existing portfolio of relevant or related resilience measurement efforts and notes gaps and challenges associated with them. It describes how some communities build and measure resilience, and offers four key actions that communities could take to build and measure their resilience to address gaps identified in current community resilience measurement efforts. The report also provides recommendations to the Gulf Research Program to build and measure resilience in the Gulf of Mexico region.
This plan represents the efforts of the State of Minnesota in fulfilling the responsibility for hazard mitigation planning. The purpose of this plan is to identify the state’s major hazards, assess the vulnerability to those hazards, and take steps to reduce vulnerability using the technical and program resources of Minnesota agencies. The process has included consideration of current and expected future impacts from Minnesota’s already changing climate, as relevant to hazard mitigation planning. The plan identifies goals and recommends actions and initiatives for the state government to adapt to, reduce, and/or prevent injury and damage from hazardous events.
Georgetown Climate Center (GCC) prepared this report to help the Eastern Shore Climate Adaptation Partnership (ESCAP) identify strategies for adapting to increasing sea level rise and flood risk in the Eastern Shore region of Maryland. ESCAP worked with the Eastern Shore Regional GIS cooperative to assess sea level rise vulnerabilities in the six counties and two municipalities that participate in ESCAP. GCC and the University of Maryland Environmental Finance Center helped to identify potential legal and policy options for enhancing flood resilience in Eastern Shore communities. This report summarizes how more rural jurisdictions, like those on the Eastern Shore, can enhance flood resilience by updating local land use ordinances and floodplain regulations and by pursuing other non-regulatory options, including acquiring flood-prone properties, preserving open space in the floodplain, and coordinating regionally on public outreach and education programs.
This report offers the first national assessment of the scope and consequences of urban flooding in the United States. Researchers analyzed available data concerning urban flooding, surveyed municipal flood and stormwater managers, and met with professionals whose disciplines intersect with urban flooding at the local, state, and national level. The research team's findings affirm that urban flooding is a national and significant source of economic loss, social disruption, and housing inequality. This report presents the full results of the study, addresses governance issues that affect urban flood risk reduction, examines critical challenges, and offers recommendations for actions.
