To help Americans anticipate how changing climate conditions might affect their homes and businesses, the United States Global Change Research Program conducts a comprehensive review of scientific information on climate trends and impacts in our country every four years. The 5th National Climate Assessment — often referred to as NCA5 — was published in 2023.

This Interactive Atlas provides access to data compiled for NCA5. Browse the collection for your own investigations, or access the data for custom analysis and mapping.

The Fifth National Climate Assessment is the US Government’s preeminent report on climate change impacts, risks, and responses. It is a congressionally mandated interagency effort that provides the scientific foundation to support informed decision-making across the United States.

The New York State Climate Impacts Assessment explores current and future climate change impacts to New York State communities, ecosystems, and economy. The New York State Energy Research and Development Authority (NYSERDA) assembled more than 250 New York–based, national, and Indigenous climate science experts and representatives from diverse communities and industries across the state to contribute to this assessment. The findings are intended to help residents, businesses, and decision-makers across the state plan and prepare for climate change impacts.

This study by Seth et al. provides up-to-date information on observed trends and projections of temperature and precipitation in Connecticut.

The City of New Haven has installed 286 right-of-way bioswales throughout the city as part of a multifaceted approach to reducing flooding in the downtown area. Right-of-way bioswales are engineered planted areas that are located on sidewalks. They are designed to capture and infiltrate stormwater into the ground that would otherwise directly enter a storm drain. These bioswales were installed as the result of various partnerships and funding opportunities related to flood prevention, localized drainage solutions, combined sewer overflow mitigation, research, and traffic calming projects.

This project consists of 750 feet of shoreline in Stratford, CT. The goal of the project was to protect the beach from coastal erosion and to help combat sea level rise. The steps consisted of adding a smooth cordgrass marsh, artificial shellfish reefs (reef balls), high marsh, and a coastal dune area. The site was awarded the “Best Restored Shore Area” from the American Shore and Beach Preservation Association. To adaptively manage the site, a second restoration project is being developed to extend the marsh seaward by 0.35 acres over an additional 250 feet of shore using a combination of bagged slipper shell and small, modular oyster castles near the marsh edge, along with additional cordgrass plantings in the intertidal zone.

In 2023, Long Island Sound Study, New York Sea Grant and Warren Pinnacle, in partnership with committed municipalities and marsh-conservation groups/organizations, developed a Plan to understand the benefits, threats and recommended conservation actions at seven focal areas across the harbors. The goal of the Plan is to inform local municipalities and marsh-conservation groups as to where they might focus their conservation efforts to maximize the conservation of marsh ecosystem services under sea-level rise conditions. Seven focal areas across Oyster Bay & Cold Spring Harbor: Frost Creek, Mill Neck Creek, West Shore Road, Bayville Bridge to Centre Island, Centre Island, Shore Road, and Lower Cold Spring Harbor.

In 2023, Long Island Sound Study and Warren Pinnacle, in partnership with committed municipalities and conservation groups/organizations, developed a Plan to understand the benefits, threats, and recommended conservation actions for the Stony Brook Harbor and West Meadow Creek marsh ecosystem. The goal of the Plan is to help inform conservation and restoration efforts to maximize marsh ecosystem services under rising sea levels.

This comprehensive study and plan, funded through the National Fish and Wildlife Foundation, Long Island Sound Futures Fund, identifies initial strategies to maintain and enhance the local watershed resources of Crab Meadow. It is meant to be a land management tool to guide the implementation of best practices. The plan was developed in consultation with many partners and stakeholders.

In 2023, Long Island Sound Study and Warren Pinnacle, in partnership with Westchester County and conservation groups/organizations, have developed a Plan to understand the benefits of, threats to, and recommended conservation actions for marsh ecosystems on Glen Island Park in New Rochelle, NY. The goal of the Plan is to help inform conservation and restoration efforts to maximize marsh ecosystem services under rising sea levels.

Coastal Resilience is a Connecticut-based decision support tool that provides local, regional, state and national stakeholders a step-wise process to guide decisions to reduce the ecological and socio-economic risks of coastal and inland hazards.

This mapper is intended to provide federal, state, and local managers with tools to estimate the vulnerability and ecosystem service potential of wetlands. It allows you to display information on the unvegetated to vegetated ratio (UVVR), marsh elevation, tidal range, and shoreline change rates for New York’s tidal wetlands.

Save the Sound’s Sound Health Explorer displays information on water quality for Long Island Sound beaches, embayments, and open waters.

Developed by The Nature Conservancy, this tool identifies priority road-stream and tidal crossings in Suffolk County for replacement or upgrades. Prioritization is based on social and ecological criteria. Additionally, it includes data on current and future projected flooding and marsh extent under various sea level rise scenarios. The tool is meant to be a screening tool for planning efforts.

The Long Island Tidal Wetlands Trends Analysis measures wetlands loss and changes in marsh condition within the Long Island Sound, Peconic, and South Shore estuaries including all or parts of Westchester, Bronx, Queens, Nassau, and Suffolk Counties between 1974 and 2005/2008. The results of this project are intended for use by environmental managers, conservation advocates and elected officials across a variety of regulatory agencies, environmental organizations, and governments.
