Compare Report Card Values

Our report cards project sea-level height relative to land in the year 2050 for 32 U.S. coastal localities. Here we summarize the latest projections for easier comparison. For a general understanding of why sea level varies from place to place and year to year, visit our Processes page. To view the suite of processes influencing sea-level trends at a regional scale, visit our East Coast, Gulf Coast, and West Coast pages. For full technical details, read our report.

Our most-likely 2021 projections of sea level in 2050 (orange dots) exceed for all East and Gulf coast localities the worst-case scenario considered in the latest assessment from the U.N.’s Intergovernmental Panel on Climate Change (blue dotted line). The plotted value of 0.28 meters is higher than the 0.23-meter value cited in the IPCC’s sixth assessment report to account for the 0.5-meter rise in sea level observed between the mid-points of the different tide-gauge intervals used to calculate the VIMS and IPCC sea-level baselines. For details, see text and our background pages.

 

Trend Values for Latest Year

Below we compare the latest rise rates and acceleration values for each of our NOAA tide stations. Together, these values determine the year-to-year changes in sea level relative to land at each station. Mouse over and tab the charts for further details.

*Note that we include Key West in both our East Coast and Gulf Coast analyses.
