These data sets contain the sea level projections associated with the Intergovernmental Panel on Climate Change Sixth Assessment Report. The dataset groups contain the full set of samples for the global projections (see IPCC AR6 WGI Sea Level Projections global) as well as summary relative sea level projections (see IPCC AR6 WGI Sea Level Projections regional and, without the AR6 estimate of background sea level process rates, see IPCC AR6 WGI Sea Level Projections regional novlm). The confidence output files correspond most directly to the figures and tables in the report.
The IPCC AR6 sea level change projection files are provided in a simplified format but represent a more complicated workflow involving combinations of multiple lines of evidence for the various individual contributors to sea level change. It's highly recommended using the data as provided in the confidence output files to remain consistent with the assessment in IPCC AR6 Chapter 9 (see IPCC AR6 WGI Sea Level Projections HowTos for details).
Required Acknowledgements and Citation: In order to document the impact of these sea level rise projections, users of the data are obligated to cite chapter 9 of WGI contribution to the IPCC AR6, the FACTS model description paper, and the version of the data set used. When using these data in a publication, please include the information provided in IPCC AR6 WGI Sea Level Projections Acknowledgments.
