Interagency Sea Level Rise Scenario Tool
Interagency Sea Level Rise Task Force (hosted by NASA) · released 2022, from the Interagency Sea Level Rise Technical Report
Visit Interagency Sea Level Rise Scenario Tool
A map of U.S. tide-gauge points where you pick a decade (relative to 2000) and a scenario from Low to High to see projected relative sea-level rise at that gauge, with a full projection for each gauge out to 2150. It gives values at points rather than flood-extent areas.

Strengths and Limitations
- Top 3 strengths
- The federal reference scenarios that state and local guidance builds on
- A full projection per gauge, out to 2150
- Openly licensed source data
- Top 3 limitations
- Point values at tide gauges only, no flood-extent areas
- Only a handful of gauges along the California coast
- Relative sea-level rise only, with no storm surge or flooding depth
