This report documents the efforts of seven partnerships to build resilience of natural resources in the United States. These partnerships demonstrate the benefits of using existing collaborative, landscape-scale conservation approaches to address climate change and other resource management challenges. Their goal is to build and maintain an ecologically connected network of terrestrial, coastal, and marine conservation areas that are likely to be resilient to climate change, demonstrating some ability to support a broad range of fish, wildlife, and plants under changing conditions.
Since 2010, United Nations Environment (UNEP) has produced annual Emissions Gap Reports based on requests by countries for an independent scientific assessment of how actions and pledges by countries affect the global greenhouse gas emissions trend, and how this compares to emissions trajectories consistent with the long-term goal of the United Nations Framework Convention on Climate Change. The difference has become known as the emissions gap. In addition to estimating the emissions gap, the reports focus on key options for achieving the emissions reductions necessary to bridge the gap, and provide an assessment of how these can be accelerated and scaled up. Countries have found these emissions gap assessments useful in informing the political process. This seventh Emissions Gap Report is based on requests by countries for an update that focuses on some of the key issues emerging with the adoption of the Paris Agreement and its specific long-term temperature goal.
The Western Regional Action Plan was developed to increase the production, delivery, and use of climate-related information to fulfill the NOAA Fisheries mission in the region, and identifies priority needs and specific actions to implement the NOAA Fisheries Climate Science Strategy in the West over the next three to five years. The California Current Large Marine Ecosystem (CCLME) spans the entire west coast of the continental U.S. and has significant seasonal, inter-annual, and inter-decadal fluctuations in climate that impact the marine food-web and fisheries. The CCLME is highly important economically and ecologically. Commercial and recreational fisheries in the CCLME contribute significantly to the U.S. economy, and a host of fish, bird, and mammal species depend on the productive waters and lipid-rich food web of the CCLME for their annual feeding migrations. Migrant species include several million metric tons of hake and sardine from the waters off southern California, several hundred million juvenile salmon from U.S. West Coast rivers, millions of seabirds from as far as New Zealand (sooty shearwaters) and Hawaii (Laysan and black-footed albatrosses), and tens of thousands of grey whales from Baja California and humpback whales from the Eastern North Pacific. These feeding migrations allow species to load up on energy reserves as an aid to survival during their winter months in southern extremes of their distribution. Climate-related physical processes that disrupt the CCLME ecosystem may result in negative impacts to U.S. fisheries, migrant species, and the people and communities that depend on these living marine resources.
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 makes a case for the One Water approach, highlighting successful strategies and real-world examples of One Water management in practice. The roadmap highlights approaches that water utilities, businesses, agricultural groups, and municipalities, are implementing to build a secure water future for all. The roadmap is organized around six arenas for action: Reliable and Resilient Utilities, Thriving Cities, Competitive Business and Industry, Sustainable Agricultural Systems, Social and Economic Inclusion, and Healthy Waterways.
This report provides educators and advisors information, perspective, and resources to help farmers in the Midwest and Northeast prepare for, cope with, and recover from the adverse impacts of a changing climate. Developed collaboratively by scientists, conservationists, and educators, the report translates the best available climate science into usable resources for making climate-informed decisions. Flexible and adaptive management are key to reduce risk, increase resilience to potential disruptions, and even take advantage of opportunities presented by climate change. The Adaptation Workbook provides a structured process to consider potential climate change impacts, management challenges and opportunities, and climate adaptation responses.
Climate change affects human health by making extreme heat more common, more severe, and last longer. That is expected to continue into the future. This handbook explains the connection between climate change and extreme heat events, and outlines actions citizens can take to protect their health during extreme heat. This resource builds on the 2006 Excessive Heat Events Guidebook from the Environmental Protection Agency (EPA), and includes up-to-date climate information from recent climate assessment reports, such as the 2014 Third National Climate Assessment, the 2016 Impacts of Climate Change on Human Health in the United States, and EPA’s 2016 Climate Change Indicators in the United States.
This report promotes a relatively simple solution to the problem of increasing heat and air pollution in cities: plant more trees. Trees cool the air by casting shade and releasing water vapor, and their leaves can filter out fine particulate matter (PM)—one of the most dangerous forms of air pollution, generated from burning biomass and fossil fuels.
The report documents analysis that tree planting efforts could improve the health of millions of people, and that trees are as cost-effective as many other common solutions. The report also shows that most of the cooling and filtering effects created by trees are fairly localized, so densely populated cities—as well as those with higher overall pollution levels—tend to see the highest overall return on investment (ROI) from tree plantings.
This report describes key accomplishments and highlights opportunities for federal agencies and stakeholders to work together on a shared climate resilience agenda. The report builds on lessons learned and outlines three major areas where opportunities exist for innovation, economic growth, and collaboration: through application of science-based data and tools, support for community resilience initiatives, and integration of climate resilience into federal agency missions, operations, and culture.
This handbook summarizes the current state of National Park Service (NPS) climate adaptation and key approaches currently in practice or considered for climate change adaptation in coastal areas in order to guide adaptation planning in coastal parks. The chapters focus on policy, planning, cultural resources, natural resources, facility management, and communication/education. The handbook highlights processes, tools, and examples that are applicable to many types of NPS plans and decisions. One chapter includes a case study of Hurricane Sandy response and recovery strategies, including changes to infrastructure. Another chapter features practical coastal infrastructure information, including cost per unit length of constructed features (including seawalls, beach nourishment, and nature-based features). The level of detail varies by topic depending on the state of research and practice in that field.
With insight from 26 campus and stakeholder advisors, the support of the USDA Agricultural Marketing Service’s Transportation Division, and input from regional food supply chain businesses throughout the region, this 68-page report details the process used to assess the Chicago region food system and findings through the three-year participatory research effort. It includes eleven sections with 17 figures to illustrate key concepts, along with extensive supporting materials. The report presents three innovations with proofs of concept that could be applied widely in the region and beyond to improve food distribution, both in rural and urban regions.
Blacksburg's Climate Action Plan represents both a short- and long-term set of strategies to pursue to reach the community’s energy and climate action goals. The long-range goal, established by Town Council in 2007, is to reduce community-wide greenhouse gas emissions by 80 percent below 1990 levels by 2050. Blacksburg’s Climate Action Plan is divided into six chapters covering the major sectors of the community responsible for Blacksburg’s greenhouse gas emissions. Citizens' priority strategies are reflected in each of the sector chapters in three ways: a set of “Individual Actions” that citizens can choose to adopt in their own lives, shorter time-horizon “Let’s Get Started” strategies, and longer-term “Looking Ahead” strategies.
The Alaska Regional Action Plan (ARAP) for the Southeastern Bering Sea was developed to increase the production, delivery, and use of climate-related information to fulfill the NOAA Fisheries mission in the region, and identifies priority needs and specific actions to implement the NOAA Fisheries Climate Science Strategy in the region over the next three to five years. NOAA’s Alaska Fisheries Science Center is responsible for marine resources in five large marine ecosystems—the southeastern Bering Sea, the Gulf of Alaska, the Aleutian Islands, the northern Bering and Chukchi seas, and the Beaufort Sea. The first ARAP focuses on the southeastern Bering Sea because it supports large marine mammal and bird populations and some of the most profitable and sustainable commercial fisheries in the United States. Climate-related changes in ocean and coastal ecosystems are already impacting the fish, seabirds, and marine mammals as well as the people, businesses, and communities that depend on these living marine resources.
As climate changes and ocean temperatures rise, the abundance, distribution, and life cycles of fish in federally managed ocean fisheries may change too. Federal agencies managing ocean fisheries have limited information to determine exactly how climate change might harm specific fish populations, and may not always understand the potential effects. To better manage climate-related risks, the report recommends (1) the development of guidance on how to incorporate climate information into the fisheries management process, and (2) finalizing Regional Action Plans for implementing the NOAA Fisheries Climate Science Strategy that incorporate performance measures for tracking achievement of the Strategy’s Objectives.
This Web toolkit raises airport operator awareness about vulnerabilities caused by significant weather events. The toolkit helps airports develop more robust contingency and recovery plans, in addition to their airport emergency plans. The toolkit focuses on events that are “rare but plausible”; that is, events that may have happened in the distant past, or in adjacent geographic areas, but are not common event types at the airport itself, and therefore may not be in the forefront of the airport managers’ minds.
This guide provides basic assistance to electric utilities and other stakeholders in assessing vulnerabilities to climate change and extreme weather and in identifying an appropriate portfolio of resilience solutions. The guide is also part of a broader DOE effort to inform preparedness, resilience planning, and response initiatives.
This two-part report is the result of workshops convened in 2015 and 2016. The Part 2 reports documents the second workshop, which brought federal and state coastal managers together with statutory authorities for review and permitting of marine aquaculture in federal waters off the coast of southern California with scientists and other stakeholders.

The report also highlights emerging technologies that the Department of Energy believes have the potential to transform our energy sector over the next five to ten years. These include fuel-efficient technologies for heavy trucks, smart building controls, and vehicle lightweighting. Along with updates in these areas, the report also highlights the accomplishments and potential of fuel cells, industrial energy management, grid-scale batteries, and big area additive manufacturing.
This two-part report is the result of workshops convened in 2015 and 2016. The Part 1 report documents participants' efforts to develop frames of reference and rationale for creation of an offshore finfish aquaculture industry in southern California.
This Health Impact Assessment was done in conjunction with the development of an adaptation plan, with the goal of ensuring that the strategies developed would be health-focused before implementation. By conducting the HIA during the Climate Change Adaptation Plan’s development, greater efficiencies were created in terms of addressing strategy-specific, health-related issues that could be avoided at the start, rather than discovering them after the strategies had already been implemented. This report is the culmination of the HIA process and summarizes each step of the assessment, including the HIA Project Team and Advisory Committee’s recommendations for improving the Climate Change Adaptation Plan. The adoption of these recommendations will increase the value relevance of the adaptation plan and benefit the health of the region.
Shaktoolik, a community on the eastern edge of Norton Sound in Alaska, faces considerable threats from erosion and flooding. The community decided to take a “defend in place” approach to erosion, allowing residents to remain at the current village site for the immediate future, although residents have indicated that they are interested in eventually relocating. This Strategic Management Plan provides the “blueprint” or framework for how the community and agencies will proceed to make Shaktoolik a more resilient community and to support their “defend in place” efforts.
Climate change impacts ecosystems in many ways, from effects on species to phenology to wildfire dynamics. Assessing the potential vulnerability of ecosystems to future changes in climate is an important first step in prioritizing and planning for conservation. Although assessments of climate change vulnerability commonly are done for species, fewer have been done for ecosystems. To aid regional conservation planning efforts, this report assesses climate change vulnerability for ecosystems in the Southeastern United States and Caribbean.
The cold temperatures of Alaska have led to the storage of vast quantities of soil and vegetation carbon, yet high-latitude ecosystems are potentially more vulnerable to higher temperature changes than ecosystems in the temperate zone. In particular, these increases in temperature may expose the substantial stores of carbon in the region to loss from more wildfire and permafrost thaw, which could turn the ecosystems of Alaska into a net carbon source. The assessment of Alaska ecosystem carbon stocks and fluxes, as well as methane fluxes, as reported here was conducted to better understand the baseline and projected carbon distributions and potential responses to a rapidly changing environment.
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.
This guide provides a step-by-step approach for incorporating climate change information into new or existing conservation plans in coastal environments. The guide’s six steps draw from existing strategic conservation planning frameworks, but focus on climate considerations and key resources specifically relevant to the coastal environment, including coastal watersheds.
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 report provides guidance for evaluating how sea level rise and storm surge hazards may impact the ability to provide electricity service, and for identifying and implementing solutions to enhance resilience. The document includes examples of various tools, methods, and information resources that can assist in resiliency planning. In addition, climate resilience challenges and opportunities for different types of generation, transmission, and distribution assets are identified. It also includes general methods on how to estimate the costs and benefits of resilience measures.
An analysis of 45 years of U.S. Forest Service records from the western U.S. show that the number of large fires on Forest Service land is increasing dramatically. The area burned by these fires is also growing at an alarming rate.
Communities and nations of the 21st century face a great challenge: to protect people from the harm caused by an increasingly volatile climate. The damaging impacts of climate change will grow as the climate changes and adaptation fails to keep pace, unless societies take steps to increase their resilience through aggressive action on both climate mitigation and adaptation.
This report focuses on adaptation, where choosing among possible actions is often not straightforward or intuitive, and highlights 15 principles for decision makers to use to prioritize investments in climate change adaptation.
A number of utilities across the country participating in the Department of Energy's Partnership for Energy Sector Climate Resilience have completed climate change vulnerability assessments. They used a variety of approaches to examine vulnerabilities affecting different categories of utility assets and operations, and the climate stressors of concern varied by region and by utility. This report details current practices, lessons learned, and needs identified by partners in conducting these assessments.
The U.S. Government Accountability Office examined the approaches of five governments on enhancing resilience through climate change adaptation. This report focuses on fiscal exposure to climate-related risks and describes how selected governments have approached enhancing resilience to weather-related disasters through climate change adaptation and steps the U.S. government has taken to enhance resilience through climate change adaptation.
In 2014, the U.S. Geological Survey, in cooperation with the Association to Preserve Cape Cod, the Cape Cod Commission, and the Massachusetts Environmental Trust, began an evaluation of the potential effects of sea-level rise on water table altitudes and depths to water on central and western Cape Cod, Massachusetts. Researchers found that the potential does exist for groundwater inundation in some areas, but the effects of sea-level rise on depths to water and infrastructure likely will not be substantial on a regional level.
This guide (NIST Special Publication 1190) outlines a practical six-step planning process to help communities establish affordable priorities and allocate resources to improve their resilience. With the guide, community leaders can incorporate resilience-driven, short- and long-term goals into their exising plans in order to preserve and enhance economic competitiveness.
This assessment strengthens and expands our understanding of climate-related health impacts by providing a more definitive description of climate-related health burdens in the United States. It builds on the 2014 National Climate Assessment and reviews and synthesizes key contributions to the published literature. The findings represent an improvement in scientific confidence in the link between climate change and a broad range of threats to public health, while recognizing populations of concern and identifying emerging issues. The overall findings underscore the significance of the growing risk climate change poses to human health in the United States.
A multi-agency team of researchers developed this Department of Defense report to provide regionalized sea level and extreme water level scenarios for the years 2035, 2065, and 2011 for 1,774 military sites worldwide. The information included in the report is meant to assist decision makers and others in making robust choices to manage their risk of future sea level and extreme water levels.
President Obama issued this Memorandum and Action Plan on building long-term drought resilience under his Climate Action Plan. The document elucidates the role of the National Drought Resilience Partnership, a team of federal agencies, in helping communities manage the impact of drought by linking information—such as forecasts and early warnings—with drought preparedness strategies in critical sectors like agriculture, municipal water systems, tourism, and transportation.
