New High-Resolution Sea-Level Rise Projections Released for U.S.
New High-Resolution Sea-Level Rise Projections Released for U.S.
US · Published Jul 15, 2026
A new geospatial dataset has been developed to provide detailed projections of sea-level rise (SLR) and its potential impacts across the United States and its territories.
This dataset integrates data from the 2022 NOAA technical report and the US Army Corps of Engineers' Sea-Level Rise Calculator.

Impact & Risks

The dataset highlights areas at risk of inundation due to rising sea levels, with significant implications for coastal communities, infrastructure, and ecosystems. Variability in tidal dynamics and data resolution may lead to localized uncertainties, particularly in regions like Puerto Rico and the Pacific Northwest. The projections are most reliable for near-term scenarios but become less certain for later decades due to increasing variability in SLR estimates. These insights are critical for policymakers, urban planners, and community groups to prioritize adaptation measures and mitigate risks associated with SLR.
