Sea Level Projection Tool

Description

Under a warming climate, sea levels around the world have been rising and are projected to continue rising in the future.  The NASA Sea Level Projection Tool allows users to visualize and download the sea level projection data from the IPCC 6th Assessment Report (AR6). The goal of this tool is to provide easy and improved access and visualization to the consensus projections found in the report. 

The tool allows users to view both global and regional sea level projections from 2020 to 2150, along with how these projections differ depending on future scenario. Users can click on a point anywhere in the ocean to obtain the IPCC projection of sea level for that individual location. The contributions of different physical processes to future sea-level rise are also provided, indicating which processes will be the dominant drivers of future sea level for a given location. Finally, users can download the sea level projection data from the IPCC 6th AR6 in multiple formats. The projections shown in the tool are consistent with those in the IPCC 6th Assessment Report and information in the tool will be linked directly to the report when available. Sea level projections consider only processes for which projections can be made with at least medium confidence are provided, relative to the period 1995–2014 for five Shared Socioeconomic Pathway (SSP) scenarios (described in the IPCC 6 Assessment Report).
