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.
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 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.
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.
This report provides the first state-wide assessment for Hawai'i documenting vulnerability to sea level rise. The report includes recommendations to reduce exposure and sensitivity to sea level rise and to increase capacity to adapt. It also provides recommendations based on emerging practices framed through extensive stakeholder consultations. It is considered a "living" report, and will be updated as further information is gathered. The framework of the report is intended to be used when facing other climate change threats affecting Hawai'i.
The Pacific Islands 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 Pacific Islands over the next three to five years. The Pacific Islands Region spans a large geographic area including the North and South Pacific subtropical gyres and the archipelagic waters of Hawaii, American Samoa, Guam, the Commonwealth of the Northern Marianas Islands, and the U.S. Pacific remote island areas. The Pacific Islands region supports a wide variety of ecologically and economically important species and habitats, from coral reefs to pelagic fish stocks. Climate-related changes in the region include a rise in ocean temperatures, reduced nutrients in the euphotic zone, an increase in ocean acidity, a rise in sea level, and changes in ocean currents. Many of these changes have already been observed and are projected to increase further. These changes will directly and indirectly impact insular and pelagic ecosystems and the communities that depend upon them.
The Hawai‘i Fresh Water Initiative was launched in 2013 to bring multiple, diverse parties together to develop a forward-thinking and consensus-based strategy to increase water security for the Hawaiian Islands. This Blueprint is the result of the work of the Hawai‘i Fresh Water Council, and provides Hawai‘i policy and decision makers with a set of solutions that have broad, multisector support in the fresh water community that should be adopted over the next three years to put Hawai‘i on a path toward water security. The ultimate goal of the initiative is to create 100 million gallons per day in additional, reliable fresh water capacity for the islands by 2030. The report outlines three aggressive water strategy areas with individual targets.
This report provides a basic summary of the observed and projected changes to the ecosystems in Hawai'i and their resulting impacts for residents.
This report examines climate change impacts in Hawai'i and also assesses the adaptive capacity of the Pacific Island communities.
This report assesses the state of climate knowledge, impacts, and adaptive capacity of Hawai‘i and the U.S.-Affiliated Pacific Islands (USAPI). Federal, state, and local government agencies, non-government organizations, businesses, and community groups worked together to produce the report. Its aim is to inform people about climate and help them prioritize their activities in the face of a changing climate.
This document sets forth a plan, required by Hawai'i's 2007 Session Laws, to achieve the maximum practically and technically feasible reductions in greenhouse gas emissions to or below 1990 levels of emissions by 2020.
This document, known as the COEMAP, provides a framework for community discussion and assessment of coastal erosion and beach loss in Hawai'i. The objective of COEMAP, and the public dialogue it seeks to foster, is to outline socioeconomic and technical mechanisms for conserving and restoring Hawai'i’s beaches in a framework of mitigating erosion impacts and reducing exposure to coastal hazards for future generations.
