The 2024 U.S. Sea Level Report Cards from the Virginia Institute of Marine Science (VIMS) reveal that Gulf Coast states, particularly Louisiana and Texas, continue to experience some of the fastest rates of sea-level rise in the country.
Published annually, the VIMS sea-level report uses observed tide gauge data to track sea-level trends across the United States and project future changes based on this long-term record. This year’s edition debuts a sleek, user-friendly interactive map that compiles data from 35 coastal communities, offering localized insights and projections through 2050.
A key finding in this year’s report is the accelerated sea-level rise now being observed in the southeastern U.S., including Georgia and South Carolina. Along the East Coast, sea levels are rising steadily, driven in part by meltwater redistribution from the Greenland ice sheet. Meanwhile, much of the West Coast has shown unexpected stability, defying earlier predictions.
The VIMS dashboard is grounded in over 55 years of tide-gauge measurements from locations stretching from Alaska to Florida. This long-term dataset allows for precise tracking of both historical trends and accelerating rates of sea-level change at each site.
Each report card includes monthly sea level averages, notes short-term anomalies like storm surges, and incorporates longer-term climate influences such as El Niño. Importantly, the projections factor in observed acceleration and compare future water levels under both linear and accelerating scenarios, providing a range of possibilities within a 95% confidence interval to aid coastal planning and risk management.
You can explore sea-level rise projections for other countries (as well as additional regions within the United States) using the Climate Change Sea-Level Map. Climate Risk’s Coastal Risk Map also lets you assess your flood risk based on projected sea-level rise, coastal flooding, elevation, and specific timeframes. By sharing your location with the map, you can view potential flood risks for different years and sea-level scenarios.
