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.

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 projections that exclude the background term (representing primarily land subsidence or uplift). It includes probability distributions for all the workflows described in AR6 WGI 9.6.3.2. P-boxes derived from these distributions are available in the sister entry 'IPCC-DDC_AR6_Sup_PBox '. These data may be of use for users who want to substitute their own estimates of the background term. 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.

This data set contains detailed elements of the sea level projections associated with the Intergovernmental Panel on Climate Change Sixth Assessment Report. In particular, it contains relative sea level projections for all of the p-boxes described in AR6 WGI 9.6.3 (see sister entries 'IPCC-DDC_AR6_Sup_PBox_PP' and 'IPCC-DDC_AR6_Sup_PBox_PPr'), as well as a variant excluding the AR6 estimates of background sea level change (see sister entries 'IPCC-DDC_AR6_Sup_PBox_woBC' and 'IPCC-DDC_AR6_Sup_PBox_woBCr'). 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.

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.
