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

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).
