Summary: This data set contains detailed elements the sea level projections associated with the Intergovernmental Panel on Climate Change Sixth Assessment Report. In particular, it contains relative sea level projection distributions for all the workflows described in AR6 WGI 9.6.3.2, as well as distributions for the components contributing to relative sea level change.
These data may be of use for users who want to substitute their own estimates. Regional projections can also be accessed through the NASA/IPCC Sea Level Projections Tool at https://sealevel.nasa.gov/ipcc-ar6-sea-level-projection-tool. See https://zenodo.org/communities/ipcc-ar6-sea-level-projections for additional related data sets.

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.
