Sea Level Explorer
Track Sea Level Change Worldwide
View past, present, and future sea level rise and impacts for coastal locations around the world.
Sea Level Explorer
The Sea Level Explorer was developed by NASA in collaboration with the United States Department of Defense, United States Department of State, The World Bank, and the United Nations Development Programme. The Explorer delivers the latest information on past, present and future sea level change for every coastal country on Earth. This information is delivered in an accessible way, coupling easy-to-understand explanations for why sea level is changing to global and authoritative sources of data. These include projections from the latest IPCC 6th Assessment Report and data from tide gauges and satellites covering the globe. Through the partnership of leading organizations that provide sea level information and tackle impacts on a global scale, this new platform provides a hub for concerned citizens and stakeholders to understand what is happening with sea level rise and coastal impacts where they are located.

About the Data
Under a warming climate, sea levels have been rising worldwide and are expected to continue, posing challenges for coastal planners and policymakers. The Sea Level Explorer, using recent observations from tide gauges and satellites, provides both recent and future flooding insights, helping stakeholders make informed decisions.
The Explorer also integrates the latest projections from the IPCC’s 6th Assessment Report (AR6) and allows users to view sea level projections globally and regionally from 2020 to 2150. By clicking on specific ocean points, users can access IPCC-based projections and see contributions from various physical processes driving sea level rise, such as ice melt and ocean warming.
Designed for a broad audience, the tool also offers options to download data directly, linking information back to the IPCC’s findings and ensuring accessibility to the consensus observations and projections essential for understanding future sea level impacts.
