Data for Figure 12.SM.2 from Chapter 12 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Figure 12.SM.2 shows regional projections for the number of days per year with NOAA Heat Index exceeding 41°C for different scenarios, time horizons and global warming levels. --------------------------------------------------- How to cite this dataset --------------------------------------------------- When citing this dataset, please include both the data citation below (under 'Citable as') and the following citation for the report component from which the figure originates: Ranasinghe, R., A.C.

Available from https://www.ipcc.ch/ --------------------------------------------------- Figure subpanels --------------------------------------------------- This figure has 43 subpanels (AR6 regions). --------------------------------------------------- List of data provided --------------------------------------------------- This dataset contains: - regional averages over 43 AR6 regions of the number of days per year with NOAA Heat Index exceeding 41°C (median value and the 10th-90th percentile range of model ensemble values across each model ensemble) over land areas for the WGI reference AR6 regions (defined in Chapter 1) for: - CMIP6 historical, ssp126 and ssp585 - CMIP5 and CORDEX historical, RCP2.6 and RCP8.5 - for the ‘recent past’ (1995-2014), mid-term (2041-2060) and long-term (2081-2100) time periods - and for three global warming levels (defined relative to the preindustrial period 1850-1900): 1.5°C, 2°C and 4°C --------------------------------------------------- Data provided in relation to figure --------------------------------------------------- Data provided in relation to Figure 12.SM.2 The regional averages for all the subpanels (AR6 regions) are stored in three json files: - CMIP5_HI41_AR6_regional_averages.json: data for the CMIP5 multi-model ensemble - CMIP6_HI41_AR6_regional_averages.json: data for the CMIP6 multi-model ensemble - CORDEX_HI41_AR6_regional_averages.json: data for the CORDEX multi-model ensemble The content of the files is organized as follows: - level 1 key: - GWL: string: 1.5, 2, 3, 4 or - name of the time slice: baseline or ${scenario}_${horizon}, with: - ${scenario}: the scenario: ssp126 or ssp585 for CMIP6, rcp26 or rcp85 for CMIP5 and CORDEX - ${horizon}: mid (mid-term) or far (long-term) - level 2 keys: name of the AR6 region - value: list with: - first element: the multi-model ensemble 10th percentile (lower bounds of the vertical lines) - second element: the multi-model ensemble median (the dots) - third element: the multi-model ensemble 90th percentile (upper bounds of the vertical lines) NOAA is the National Oceanic and Atmospheric Administration. CMIP5 is the fifth phase of the Coupled Model Intercomparison Project. CMIP6 is the sixth phase of the Coupled Model Intercomparison Project CORDEX is The Coordinated Regional Downscaling Experiment from the WCRP. SSP126 is the Shared Socioeconomic Pathway which represents the lower boundary of radiative forcing and development scenarios, consistent with RCP2.6. SSP585 is the Shared Socioeconomic Pathway which represents the upper boundary of radiative forcing and development scenarios, consistent with RCP8.5. RCP2.6 is the Representative Concentration Pathway for 2.6 Wm-2 global warming by 2100. RCP8.5 is the Representative Concentration Pathway for 8.5 Wm-2 global warming by 2100. --------------------------------------------------- Notes on reproducing the figure from the provided data --------------------------------------------------- Jupyter notebooks containing the data files and code used to plot this figure are stored in the 'scripts' GitHub repository linked in the documentation. --------------------------------------------------- Sources of additional information --------------------------------------------------- The following weblinks are provided in the Related Documents section of this catalogue ...
