Rising Seas, Changing Coasts
This site provides federally supported data visualizations coupled with explanations and science education to help communities prepare for challenges that will affect our coastal environments. By showing how sea levels are changing regionally, the site provides a foundation to inform decision-making related to coastal planning, resource management, and emergency operations.

Federal agencies have been working together on the topic of sea level rise for over a decade, conducting collaborative research to produce sea level rise projections for the U.S. as a critical input to the National Climate Assessment. In 2024, after years of informal collaboration, the U.S. Global Change Research Program officially adopted the Interagency Task Force on Sea Level Change as an interagency working group.

The mission of the Interagency Task Force on Sea Level Change is to foster meaningful interagency collaboration, co-development, and consensus on the science of sea level change and its associated impacts on ecosystems, communities, and economies.
