2022 Technical Report | Resources – U.S. Sea Level Change

Key Takeaways

Sea Level Rise

Sea level along the U.S. Coastline is predicted to rise 10 - 12 inches0.25 - 0.5 meters over the next 30 years.

Flooding

In the next 30 years, flooding is expected to occur, on average, more than 10 times as often as it does today.

Emissions

Failing to curb future emissions could cause an additional 1.5 to 5 feet0.5 to 1.5 meters of rise by the end of this century.

Tracking

Continuously tracking how and why sea level is changing is an important part of informing plans for adaptation.

The Sea Level Rise Technical Report provides the most up-to-date sea level rise scenarios available for all U.S. states and territories; decision-makers will look to it for information.

Data Download

Download the sea level scenarios and extreme water level projections from the 2022 Technical Report.

This multi-agency effort, representing the first update since 2017, offers sea level scenarios out to the year 2150 and information to help communities assess potential changes in average tide heights and height-specific threshold frequencies as they strive to adapt to sea level rise.
