title: Chapter 6 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 6.22 (v20220815)

description: Data for Figure 6.22 from Chapter 6 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Figure 6.22 shows time evolution of the effects of changes in short-lived climate forcers (SLCFs) and hydrofluorocarbons (HFCs) on global surface air temperature (GSAT) across the WGI core set of Shared Socio-economic Pathways (SSPs). --------------------------------------------------- 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: Szopa, S., V.

The GSAT changes are based on the assessed historic and future evolution of effective radiative forcing (ERF; Section 7.3.5). The temperature responses to the ERFs are calculated with an impulse response function with an equilibrium climate sensitivity of 3.0°C for a doubling of atmospheric CO2 (feedback parameter of –1.31 W m–2 °C–1, see Cross-Chapter Box 7.1). The vertical bars to the right in each panel show the uncertainties (5–95% ranges) for the GSAT change between 2019 and 2100. Further details on data sources and processing are available in the chapter data table (Table 6.SM.3). --------------------------------------------------- Data provided in relation to figure --------------------------------------------------- Data provided in relation to Figure 6.22: - Data file: fig_timeseries_dT_p95-p50_HFCs_2019-2100_refyear2019.csv - Data file: fig_timeseries_dT_p95-p50_Sum_SLCF_Aerosols_Methane_Ozone_HFCs_2019-2100_refyear2019.csv - Data file: fig_timeseries_dT_p95-p50_aerosol-total-with_bc-snow_2019-2100_refyear2019.csv - Data file: fig_timeseries_dT_p95-p50_ch4_2019-2100_refyear2019.csv - Data file: fig_timeseries_dT_p95-p50_o3_2019-2100_refyear2019.csv - Data file: fig_timeseries_dT_recommendation_HFCs_2019-2100_refyear2019.csv - Data file: fig_timeseries_dT_recommendation_Sum_SLCF_Aerosols_Methane_Ozone_HFCs_2019-2100_refyear2019.csv - Data file: fig_timeseries_dT_recommendation_aerosol-total-with_bc-snow_2019-2100_refyear2019.csv - Data file: fig_timeseries_dT_recommendation_ch4_2019-2100_refyear2019.csv - Data file: fig_timeseries_dT_recommendation_o3_2019-2100_refyear2019.csv --------------------------------------------------- Notes on reproducing the figure from the provided data --------------------------------------------------- Panels were plotted using Python and the code has been embedded in Jupyter notebooks for reproducibility - code is available in the GitHub repository linked in the documentation. --------------------------------------------------- Sources of additional information --------------------------------------------------- The following weblinks are provided in the Related Documents section of this catalogue record: - Link to the figure on the IPCC AR6 website - Link to the report component containing the figure (Chapter 6) - Link to the Supplementary Material for Chapter 6, which contains details on the input data used in Table 6.SM.3 - Link to the GitHub repository containing the Jupyter notebooks used to run the code associated with this figure. - Link to the code for the figure, archived on Zenodo.
