The State Climate Summaries provided here were initially produced to meet the demand for state-level climate information in the wake of the Third U.S. National Climate Assessment. This 2022 version provides new information and extends the historical climate record to 2020 for each state. The summaries cover assessment topics directly related to NOAA’s mission, specifically historical climate variations and trends, future climate model projections of climate conditions during the 21st century, and past and future conditions of sea level and coastal flooding. Additional background information and links are given below.
Safe and secure water supplies are a continuing fundamental pursuit for life in the West. This 2021 Report provides an assessment of climate change impacts to water uses in the West and adds a new set of West-wide information based in paleohydrology. This report describes our collaborative actions taken to increase the reliability of water and power deliveries since 2016, including: science and research, planning, infrastructure sustainability, efficient hydropower production, and on-the-ground actions to meet needs for irrigation, municipalities, power, Tribes, and the environment.
In the third quarter of 2017, Hurricanes Harvey, Irma and Maria revealed some significant vulnerabilities in the national and regional supply chains of Texas, Florida, the U.S. Virgin Islands, and Puerto Rico. Drawing on lessons learned during the 2017 hurricanes, this report explores future strategies to improve supply chain management in disaster situations. It makes recommendations to strengthen the roles of continuity planning, partnerships between civic leaders with small businesses, and infrastructure investment to ensure that essential supply chains will remain operational in the next major disaster. Focusing on the supply chains food, fuel, water, pharmaceutical, and medical supplies, the recommendations of this report will assist FEMA as well as state and local officials, private sector decision makers, civic leaders, and others who can help ensure that supply chains remain robust and resilient in the face of natural disasters.
This guide is designed to help transportation practitioners understand how and where nature-based and hybrid solutions can be used to improve the resilience of coastal roads and bridges. It summarizes the potential flood-reduction benefits and co-benefits of these strategies, then follows the steps in the project delivery process, providing guidance on considering nature-based solutions in the planning process, conducting site assessments, key engineering and ecological design considerations, permitting approaches, construction considerations, and monitoring and maintenance strategies. The guide also includes appendices with site characterization tools, decision support for selecting nature-based solutions, suggested performance metrics, and links to additional tools and resources.
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.
The EWN Atlas is a collection of 56 projects illustrating a diverse portfolio of contexts, motivations, and successful outcomes, presented and considered from an Engineering With Nature® perspective to reveal the usefulness of nature-based approaches and the range of benefits that can be achieved. Engineering With Nature is an initiative of the U.S. Army Corps of Engineers enabling more sustainable delivery of economic, social, and environmental benefits associated with water resources infrastructure. EWN intentionally aligns natural and engineering processes to efficiently and sustainably deliver economic, environmental, and social benefits through collaborative processes.
Green infrastructure can help to maximize the environmental, economic, and social benefits of parks. This guide from EPA encourages partnerships between park agencies and stormwater agencies to promote the use of green infrastructure on park lands to improve park lands and access to parks, better manage stormwater, increase community resiliency to shifting weather patterns, and provide funding to implement and maintain park enhancements that benefit the community. Using a stepwise approach for building relationships with potential partners, the guide includes information on how to identify and engage partners, build relationships, involve the community, leverage funding opportunities, and identify green infrastructure opportunities. It includes recommendations on the types of projects that are most likely to attract positive attention and funding and that provide a wide range of benefits. Included case studies from across the country illustrate approaches presented in the guide.
This report summarizes findings from a workshop held in El Paso, Texas, on July 13, 2016. The El Paso-Juárez-Las Cruces region is home to approximately 2.4 million people, most of whom are living in or near the urban centers of Ciudad Juárez (Chihuahua), El Paso, and Las Cruces (New Mexico). These cities share characteristics, such as a high proportion of residents of Hispanic origin, median income below the U.S. national average, and a range of climate-related environmental issues that include drought, flooding, air pollution, dust storms, and frequent occurrences of extremely high temperatures during the late spring and early summer. With hotter temperatures and more frequent and persistent heat waves projected for the El Paso-Juárez-Las Cruces region, it is critical to develop more robust systems of institutions, social learning, and partnerships to understand risks and strengthen public health resilience.
The Gulf of Mexico 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 Gulf of Mexico over the next three to five years. The Gulf contains a diverse range of habitats, including unique coral systems atop salt domes, high relief carbonate banks, and shallow coastal ecosystems that support a variety of commercially and recreationally important marine fish and shellfish. Understanding how the major climate drivers affect the distribution and abundance of marine species, their habitats, and their prey is important to effective management. Climate-related factors expected to impact the Gulf of Mexico include warming ocean temperatures, sea level rise, and ocean acidification.
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.
Historically, studies about climate hazards and social vulnerability have been conducted in separate silos. The Social Vulnerability Index (SoVI) is the first study of its kind to examine both the potential impact of natural hazards and which populations are most likely to be negatively affected. This research, commissioned by Oxfam America, includes a series of layered maps that depict social and climate change-related hazard vulnerability. The maps assist in identifying hotspots in the U.S. Southeast, which are at significant risk in the face of four particular climate change-related hazards: drought, flooding, hurricane force winds, and sea level rise. The specific region of focus is the 13-state region of the US Southeast: Alabama, Arkansas, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, South Carolina, Tennessee, Texas, and Virginia. Roughly 80 percent of all U.S. counties that experience persistent poverty (defined as a county in which at least 20 percent of the population experiences poverty for three decades or more) lie in this region.
A collection of case studies and information about how coastal communities can plan for and adapt to climate change. These resources represent a national guide for how coastal communities can plan and adapt. Case study issues range from coastal managers addressing sea level rise in Rhode Island to coral bleaching caused by rising sea temperatures in Florida.
As global temperatures increase, sea levels rise, and weather patterns change, the stewards of our nation's infrastructure are challenged to consider how these changes may affect the country's roads, airports, rail, transit systems, and ports. This study focuses on potential impacts of climate change on human infrastructure in the U.S. Gulf Coast region.
