- Achieve net zero emissions by 2050 across all sectors;
- Reduce energy burdens for rural and marginalized communities;
- Limit the use of chemicals, substances, or products that contribute to climate change; and
- Build and encourage climate adaptation and resilience of Vermont communities and natural systems.
The Climate Action Plan serves as a guide for the Vermont Legislature in setting policy that supports climate change solutions for Vermonters and Vermont's landscape.
A range of resources documenting report preparation are available in the Climate Action Plan Appendices.
The central recommendation of this report, submitted to the National Climate Task Force, is that the pursuit of a decade-long national conservation effort be faithful to eight core principles. These principles—which include a commitment to collaboration, support for voluntary and locally led conservation, and honoring of Tribal sovereignty and private property rights—are essential ingredients to building and maintaining broad support, enthusiasm, and trust for this effort. These principles are also indispensable to achieving durable outcomes that meaningfully improve the lives of Americans.
In 2020, New York City's Mayor’s Office of Resiliency initiated an engagement process, called the Climate Knowledge Exchange, to align research with climate resiliency and adaptation needs. This report is the first in an annual series that will maintain a public agenda for climate research in NYC. The report communicates NYC’s research needs to external partners, including academic scientists, federal researchers, philanthropic foundations, and community organizations. This in turn will catalyze new and creative partnerships to develop credible and actionable research products that address NYC’s most pressing climate challenges. The report includes the engagement methodology and survey text used with various agencies.
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). Threatened resources include high-value coastal infrastructure and the millions of dollars that ocean ecosystems add to the CNMI economy annually. This report provides guidance for decision makers seeking to better understand the implications of climate variability and change for CNMI and its communities and identifies the additional information and research needed to support responses that enhance resilience and help CNMI to withstand the changes to come.
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.

By working together to identify solutions and bring about positive change, we can reduce the risks faced by current and future generations.
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.
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 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.
Climate change is causing significant and far-reaching impacts on the Great Lakes and the Great Lakes region.

The frequency and severity of disasters over the last few decades have presented unprecedented challenges for communities across the United States. 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.
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 special report from the Intergovernmental Panel on Climate change describes the impacts of global warming of 1.5 °C above pre-industrial levels. The report also describes potential global greenhouse gas emission pathways, in the context of strengthening the global response to the threat of climate change, sustainable development, and efforts to eradicate poverty.
This guide contains five modules that provide best practices on conducting vulnerability assessments, collaboration among stakeholders, communicating drought preparedness and response strategies, and where to find (and how to use) data on drought.

The authors of the guide also developed and included two attractive, user-friendly handouts that can be easily customized and reproduced for community outreach.
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.
As a key part of the Fourth National Climate Assessment (NCA4), the U.S. Global Change Research Program (USGCRP) oversaw the production of this stand-alone report of the state of science relating to climate change and its physical impacts. The Climate Science Special Report (CSSR) is designed to be an authoritative assessment of the science of climate change, with a focus on the United States, to serve as the foundation for efforts to assess climate-related risks and inform decision making about responses.
As Volume 1 of NCA4, CSSR serves several purposes, including providing (1) an updated and detailed analysis of the findings of how climate change is affecting weather and climate across the United States; (2) an executive summary and 15 chapters that provide the basis for the discussion of climate science found in the second volume of NCA4; and (3) foundational information and projections for climate change, including extremes, to improve “end-to-end” consistency in sectoral, regional, and resilience analyses within the second volume. CSSR integrates and evaluates the findings on climate science and discusses the uncertainties associated with these findings. It analyzes current trends in climate change, both human-induced and natural, and projects major trends to the end of this century. As an assessment and analysis of the science, CSSR provides important input to the development of other parts of NCA4, and their primary focus on the human welfare, societal, economic and environmental elements of climate change. Much of the underlying report is written at a level more appropriate for a scientific audience, though the Executive Summary is intended to be accessible to a broader audience.
With support from the Minnesota Pollution Control Agency, the Region Nine Development Commission created this plan to assess South Central Minnesota’s vulnerability to climate change and create strategies for the region to adapt to climate change. Region Nine, working in tandem with a Climate Change Adaptation Task Force, identified eight top priority sectors to prioritize the planning process: agriculture, water, human health, energy, transportation, forests, ecosystems, business, and economy. The result of the planning process was real, actionable strategies that can be used as a guide to initiate discussions and begin a planning process in Region Nine communities.
This Technical Report presents results from a large set of sectoral impact models that quantify and monetize climate change impacts in the U.S., with a primary focus on the contiguous U.S., under moderate and severe future climates. The report summarizes and communicates the results of the second phase of quantitative sectoral impacts analysis under the Climate Change Impacts and Risk Analysis (CIRA) project. The effort is intended to inform the fourth National Climate Assessment (NCA4) of the U.S. Global Change Research Program (USGCRP). The goal of this work is to estimate climate change impacts and economic damages to multiple U.S. sectors (e.g., human health, infrastructure, and water resources) under different scenarios. Though this report does not make policy recommendations, it is designed to inform strategies to enhance resiliency and protect human health, investments, and livelihoods.
This guidebook results from the culmination of a year of dialogue among diverse stakeholders in southeastern Connecticut who defined challenges and solutions from extreme weather, climate change, and shifting social and economic conditions. Participants included representatives from nine municipalities, public and private utilities, public health departments, chambers of commerce, major employers, conservation organizations, academic institutions, community non-profits, and state agencies, among others. The dialogue captured six themed planning sectors (water, food, ecosystem services, transportation, energy, and regional economy) in a process that used surface and integrated solutions to address singular and multiple challenges across planning sectors. The guidebook provides a quick reference resource to help shape and inform actions that will advance a regional resilience framework for southeastern Connecticut; an accompanying Summary of Findings captures the project's final outcomes and conclusions, as well as providing a comprehensive account of the objectives, process, and details.
This user-friendly summary is based on the 2015 report “City of Long Beach Climate Resiliency Assessment Report" and “Appendices” prepared by the Aquarium of the Pacific at the request of Mayor Robert Garcia. The report includes clear infographics that describe current and projected conditions in the city. It also describe what the city is currently doing and what else the city and its residents can do.
This report documents that the average temperature in 2015 was over one degree higher than pre-industrial times and that the period 2011–2015 was the warmest five-year period on record, consistent with established warming trends. The report further documents that in 2015 another milestone was reached, with globally averaged CO2 levels of 400 parts per million (ppm). The year 2016 is on track to be even warmer and will be the first year in which CO2 at the Mauna Loa Observatory remains above 400 ppm all year, and for many generations to come.
The probability of extreme climate events since 2011, especially those involving extreme high temperatures, has been substantially increased by climate change, often by a factor of 10 or more. The single most significant event in humanitarian terms, with over 250,000 lives lost, was the 2011–2012 famine in the Horn of Africa, where drought was a major factor.
This report features observed trend data on 37 climate indicators, including U.S and global temperatures, ocean acidity, sea level, river flooding, droughts, and wildfires. It documents rising temperatures, shifting patterns of snow and rainfall, and increasing numbers of extreme climate events, such as heavy rainstorms and record high temperatures. Many of these observed changes are linked to the rising levels of carbon dioxide and other greenhouse gases in our atmosphere, caused by human activities.
This document provides final guidance for federal agencies on how to consider the impacts of their actions on global climate change in their National Environmental Policy Act (NEPA) reviews, providing a framework for agencies to consider both the effects of a proposed action on climate change, as indicated by its estimated greenhouse gas emissions, and the effects of climate change on a proposed action. The memorandum applies to all types of proposed federal agency actions that are subject to NEPA analysis and guides agencies on how to address the greenhouse gas emissions from federal actions and the effects of climate change on their proposed actions within the existing NEPA regulatory framework.
The National Centers for Environmental Information (NCEI) is the nation's scorekeeper in terms of addressing severe weather and climate events in their historical perspective. As part of its responsibility of monitoring and assessing the climate, NCEI tracks and evaluates climate events in the U.S. and globally that have great economic and societal impacts. Found on these webpages are information on the weather and climate events that have had the greatest economic impact from 1980 to 2015. The U.S. has sustained 188 weather and climate disasters since 1980 where overall damages/costs reached or exceeded $1 billion (including CPI adjustment to 2015). The total cost of these 188 events exceeds $1 trillion.
In January 2015, Long Beach Mayor Robert Garcia asked the Aquarium of the Pacific to take a lead in assessing the primary threats that climate change poses to Long Beach, to identify the most vulnerable neighborhoods and segments of the population, and to identify and provide a preliminary assessment of options to reduce those vulnerabilities. Over the course of 2015, the Aquarium hosted and participated in meetings and workshops with academic and government scientists, business and government leaders, local stakeholders, and Long Beach residents to discuss key issues facing our community as the result of climate change. This report, completed in December 2015, represents the culmination of these efforts. The report offers detailed assessments of the five main threats of climate change to Long Beach: drought, extreme heat, sea level rise and coastal flooding, deteriorating air quality, and public health and social vulnerability. It also provides an overview of what is currently being done to mitigate and adapt to these threats, and other options to consider. Finally, this report presents a series of steps and actions that city leaders and community stakeholders can use as a template for making Long Beach a model of a climate resilient city.
King County, Washington's Strategic Climate Action Plan sets forth strategies for reducing greenhouse gas emissions and preparing for climate change impacts.
Successfully negotiating climate change challenges will require integrating a sound scientific basis for climate preparedness into local planning, resource management, infrastructure, and public health, as well as introducing new strategies to reduce greenhouse gas emissions or increase carbon sequestration into nearly every sector of California’s economy. This Research Plan presents a strategy for developing the requisite knowledge through a targeted body of policy-relevant, California-specific research over three to five years (from early 2014), and determines California’s most critical climate-related research gaps.
This report builds on Maine’s earlier report from 2009—it is not intended as a comprehensive revision of all aspects of the original report. This update focuses on highlights of the understanding in 2015 of past, present, and future trends in key indicators of a changing climate specific to Maine, and recent examples of how Maine people are experiencing these changes.
