NASA Sea Level Projection Tool

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 Assessment Report 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 6th Assessment Report).

What you can do with it

Input

  • Select a coastal location and climate scenario.
  • Explore global and regional sea-level projections.
  • Examine the contribution of different physical drivers of sea-level rise.

Output

  • Sea-level projection maps and graphs.
  • Downloadable datasets.
  • Global and regional projections up to 2150.
  • Information on contributing physical processes.

Use it to

  • Explore future sea-level rise.
  • Compare sea-level scenarios.
  • Support coastal risk assessments.
  • Understand the drivers of future sea-level change.

Why is it relevant to climate adaptation

Makes IPCC AR6 sea-level projections accessible through an interactive and location-specific interface. Particularly useful for users who need authoritative information on future sea-level rise and want to understand why projections differ between locations and scenarios.

Used in

  • Coastal climate-risk assessment worldwide.
  • Use of IPCC AR6 sea-level projections for coastal planning.
  • Analysis of regional differences in sea-level rise.
  • Examination of physical contributors such as glacier melt, thermal expansion and ice-sheet change.
