climate change future projection IPCC IPCC-AR6 IPCC-DDC sea level WGI

Summary: 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.

Description: Sea level projections considering 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 and five different future Global Mean Surface Temperatures (from 2080-2100). The SSP scenarios are described in sections TS1.3 and 1.6 and Cross-Chapter Box 1.4 of the Working Group 1 contribution.
In the sea level projections, likely ranges are assessed based upon the combination of uncertainty in the temperature change associated with an emissions scenarios and uncertainty in the relationships between temperature and drivers of projected sea level change, such as thermal expansion, ocean dynamics, and glacier and ice sheet mass loss. In general, 17th-83rd percentile results are interpreted as likely ranges, reflecting the use of the term likely to refer to a probability of at least 66%. Note, Fewer global climate model simulations are available after 2100, which can lead to discontinuity in projections between 2100 and immediately following decades, particularly in regions where dynamic sea level effects are an important contributor.
To indicate the potential impact of deeply uncertain ice sheet processes, about which there is currently a low level of agreement and limited evidence, low confidence projections are also provided for SSP1-2.6 and SSP5-8.5. For both the Greenland and Antarctic ice sheets, the low confidence projections integrate information from the Structured Expert Judgement study of Bamber et al. (2019). For the Antarctic ice sheet, the low confidence projections> projections also incorporate results from a simulation study that incorporates Marine Ice Cliff Instability (DeConto et al., 2021). The results shown are 17th-83rd percentile projections, but are not assessed as likely ranges because of the low agreement and limited evidence. See section 9.6 and Box 9.4 for more details. For more information on the use of likelihood and confidence language by the Intergovernmental Panel on Climate Change, see Box 1.1.
