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.
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.
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.
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 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 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 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.
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.
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.
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.
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.
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.

The Arctic is changing at a startling pace. Understanding the role of freshwater in these changes—both how Arctic freshwater systems are affected by climate change, and how changes to the Arctic freshwater system will affect other environmentally relevant processes—is critical to understanding how these changes will affect the lives of people living in the Arctic and beyond. This report is intended to inform the non-expert reader about these changes to the freshwater systems in the Arctic, and their implications.
The SECURE Water Report identifies climate change as a growing risk to Western water management and cites warmer temperatures, changes to precipitation, snowpack and the timing and quality of streamflow runoff across major river basins as threats to water sustainability. Water supply, quality and operations; hydropower; groundwater resources; flood control; recreation; and fish, wildlife and other ecological resources in the Western states remain at risk.
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.
The State of Maine is experiencing shifts in atmospheric and oceanographic conditions that put it at the precipice of abrupt climate change. This report—part of the Department of Homeland Security's Regional Resiliency Assessment Program (RRAP)—focuses on the local and regional consequences of climate disruptions and their impacts on critical infrastructure in the Casco Bay region, the most developed and populous region in Maine. The report identifies vulnerabilities that may potentially affect the region’s ability to maintain its critical infrastructure systems and recover from the impacts of climate change.
The U.S. Environmental Protection Agency produced this publication with assistance from federal, state, local, and academic partners. It is designed to help community officials, emergency managers, meteorologists, and others plan for and respond to excessive heat events. The guidebook highlights best practices that have been employed to save lives during excessive heat events in different urban areas. Originally published in June 2006, its Appendix A—a list of federal resources—was updated in March 2016.
As climate has warmed over recent years, a new pattern of more frequent and more intense weather events has unfolded across the globe. Climate models simulate such changes in extreme events, and some of the reasons for the changes are well understood. Warming increases the likelihood of extremely hot days and nights, favors increased atmospheric moisture that may result in more frequent heavy rainfall and snowfall, and leads to evaporation that can exacerbate droughts.
Event attribution can answer questions about how much climate change influenced the probability or intensity of a specific type of weather event. As event attribution capabilities improve, they could help inform choices about assessing and managing risk, and in guiding climate adaptation strategies. This report examines the current state of science of extreme weather attribution, and identifies ways to move the science forward to improve attribution capabilities.
Rapidly rising seas threaten to drown tidal marshes and diminish the benefits provided to people and wildlife by these valuable coastal ecosystems. Increasingly, government agencies and non-government organizations are harnessing the power of computer-based models of marsh ecosystems to inform management and policy strategies to sustain tidal marshes. This report covers the entire modeling lifecycle, from developing a modeling approach and working with data to communicating modeling results. While some of the information pertains specifically to the northeastern United States, the report is also intended as a useful resource for modeling of marsh migration in other regions. The report is available online, with a printer-friendly version also available for download.
Drought threatens our country’s natural resources, economy, and overall health. Increasingly, NOAA is charged with providing and improving information that helps stakeholders at all levels manage water resources in a more resilient and climate-smart manner. Working with input from farmers, ranchers, natural resource managers, and other drought-impacted industries and populations, NOAA research has worked to improve drought monitoring and prediction for better planning and mitigation of impacts.
Occupational exposure to heat can result in injuries, disease, reduced productivity, and death. To address this hazard, the National Institute for Occupational Safety and Health evaluated the scientific data on heat stress and hot environments and updated these criteria (last updated in 1986). This revision includes information about physiological changes that result from heat stress; evidence to redefine heat stroke and associated symptoms; and updated information on physiological monitoring and personal protective equipment and clothing that can be used to control heat stress.
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.
On Earth Day 2015, Connecticut Governor Malloy issued Executive Order 46 creating the Governor’s Council on Climate Change, also known as the GC3. The Council is to examine the effectiveness of existing policies and regulations designed to reduce greenhouse gas emissions and identify new strategies to meet the state’s greenhouse gas emissions reduction target of 80 percent below 2001 levels by 2050. It will do so, in part, by developing interim state-wide greenhouse gas reduction targets for years between 2020 and 2050 and by identifying short- and long-term statewide strategies to achieve the necessary reductions.
Climate.gov's El Niño-Southern Oscillation—or ENSO—page provides information on the current status of El Niño and La Niña, plus links to forecasts, maps, and videos from across NOAA that help explain the impacts of the ENSO on the U.S.
Urban populations are facing increasing challenges from numerous natural and man-made pressures, such as rapid urbanisation, climate change, terrorism, and increased risks from natural hazards. Cities must learn to adapt and thrive in the face of these diverse challenges—they must learn how to build resilience in an uncertain world. Armed with this knowledge and understanding, governments, donors, investors, policy makers, and the private sector will be able to develop effective strategies to foster more resilient cities. Supported by the Rockefeller Foundation, the City Resilience Index is being developed by Arup. It builds on extensive research undertaken by Arup to establish an accessible, evidence-based definition of urban resilience, which culminated in the publication of the City Resilience Framework (CRF) in April 2014. This provides a holistic articulation of city resilience, structured around four dimensions and 12 goals that are critical for the resilience of our cities. This structure also forms the foundations of the CRI.
The Global Warming Solutions Act of 2008 required the Massachusetts Secretary of Energy and Environmental Affairs to set a limit on greenhouse gas emissions that would lead to a 10–20 percent reduction in emissions by 2020, and an 80 percent reduction by 2050. This update to Massachusetts' 2010 Climate Action Plan includes recommendations on how to achieve this goal.
Flooding and sea level rise are challenges the City of Charleston has taken seriously for centuries. However, this City that we love is experiencing the effects more frequently than ever. In the 1970s Charleston experienced an average of 2 days of tidal flooding per year and it is projected that the City could experience 180 days of tidal flooding in 2045. Identifying initiatives that will improve our ability to withstand these effects is timely. This
Sea Level Rise Strategy Plan is that comprehensive inventory of initiatives.
This report documents recommendations made by the Virginia Climate Commission and describes how they were acted upon. Highlights include appointment of a Chief Resilience Officer and development of a protocol for sea level rise projections. The report also makes 113 recommendations to help Virginia adapt to the consequences of climate change, and to reduce Virginia’s contributions to the problem.
This peer-reviewed scientific assessment identifies climate change effects on global food security. Climate change is likely to diminish continued progress on global food security through production disruptions that lead to local availability limitations and price increases, interrupted transport conduits, and diminished food safety, among other causes. The assessment is a contribution to the U.S. National Climate Assessment, is called for under the President’s Climate Action Plan, and was led by the U.S. Department of Agriculture.
With the goal of creating a cleaner San Diego for future generations, the City of San Diego’s Climate Action Plan calls for eliminating half of all greenhouse gas emissions in the City and aims for all electricity used in the city to be from renewable sources by 2035. The Climate Action Plan is a package of policies that will benefit San Diego’s environment and economy. It will help create new jobs in the renewable energy industry, improve public health and air quality, conserve water, more efficiently use existing resources, increase clean energy production, improve quality of life, and save taxpayer money. The plan identifies steps the City of San Diego can take to achieve the 2035 targets, including creating a renewable energy program, implementing a zero waste plan, and changing policy to have a majority of the City’s fleet be electric vehicles. The Climate Action Plan helps achieve the greenhouse gas reduction targets set forth by the State of California. The City’s first Climate Action Plan was approved in 2005 and a commitment to update the plan was included in the City’s 2008 General Plan update.
