The Intergovernmental Panel on Climate Change (IPCC) is the United Nations body for assessing the science related to climate change. The IPCC was created to provide policymakers with regular scientific assessments on climate change, its implications and potential future risks. As part of this effort, the IPCC surveys and distills the scientific literature and provides consensus projections on future sea levels across the globe under a range of possible future scenarios. The most recent iteration of the IPCC’s work, the 6th Assessment Report from Working Group I, was released on August 9th, 2021.
The PO.DAAC is pleased to announce the availability of the dataset for the global and regional sea level projections from the IPCC 6th Assessment Report (AR6). The projections cover the time-period from 2020 to 2150 and are provided for all future scenarios covered in the AR6. Projections for individual processes that cause sea level to change are also included in the dataset. Globally averaged projections, regional projections on a regular global grid, and local projections at individual tide gauge locations are all provided.
The global projections data [411 KB], the regional and local projections data [9.11 GB] and a document detailing the specific contents of each dataset can be found here. The projections contained in the datasets are consistent with those in the IPCC 6th Assessment Report and the report will be linked to when available.
Additionally, 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 datasets. Scripts for visualizing the location-specific data from the Sea Level Projection Tool and full AR6 projection dataset can be found on the PO.DAAC GitHub under ipcc-ar6 repository.
