title: Chapter 7 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 7.8 (v20220721)

description: Data for Figure 7.8 from Chapter 7 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Figure 7.8 shows attributed global surface air temperature change (GSAT) from 1750 to 2019 produced using the two-layer emulator (Supplementary Material 7.SM.2), forced with ERF derived in this chapter (displayed in Figure 2.10) and climate response constrained to assessed ranges for key climate metrics described in Cross-Chapter Box 7.1. --------------------------------------------------- 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: Forster, P., T.

A link to the code to plot the figure archived on Zenodo is provided in the Related Documents section of this catalogue record. --------------------------------------------------- List of data provided --------------------------------------------------- This dataset contains: Attributed global surface air temperature change (GSAT) from 1750 to 2019 produced using the two-layer emulator (Supplementary Material 7.SM.2), forced with ERF derived in this chapter (displayed in Figure 2.10) and climate response constrained to assessed ranges for key climate metrics described in Cross-Chapter Box 7.1. The temperature contributions are expressed as follows: - carbon dioxide (CO2) - methane (CH4) - nitrous oxide (N2O) - other well-mixed greenhouse gases (WMGHGs) - ozone (O3) - aerosols - other anthropogenic forcings - total anthropogenic - solar - volcanic - total forcing The results shown are the medians from a 2237-member ensemble that encompasses uncertainty in forcing and climate response (year-2019 best estimates and uncertainties are shown in Figure 7.7 for several components). Shaded uncertainty bands show very likely (5–95%) ranges. Further details on data sources and processing are available in the chapter data table (Table 7.SM.14). --------------------------------------------------- Data provided in relation to figure --------------------------------------------------- Data provided in relation to Figure 7.8: - Data file: fig7.8.csv ERF stands for Effective Radiative Forcing. --------------------------------------------------- Notes on reproducing the figure from the provided data --------------------------------------------------- Data and figures are produced by the Jupyter Notebooks that live inside the notebooks directory of the Chapter 7 GitHub repository, which is linked in the 'Related Documents' section. Within the processing chain, every notebook is prefixed by a number. To reproduce all results in the chapter, the notebooks should be run in numerical order. --------------------------------------------------- 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 7) - Link to the Supplementary Material for Chapter 7, which contains details on the input data used in Table 7.SM.1 to 7.SM.7. - Link to the code for the figure, archived on Zenodo - Link to the Chapter 7 GitHub repository - Link to the notebook for plotting figure
