Chapter 7 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 7.17 (v20220721)
Abstract
Data for Figure 7.17 from Chapter 7 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6).
Figure 7.17 shows time evolution of the effective radiative forcing (ERF) to the CO2 concentration increased by 1% per year until year 70 (equal to the time of doubling) and kept fixed afterwards, and surface temperature response to the CO2 forcing calculated using the emulator.

List of data provided
---------------------------------------------------
This dataset contains:
- (a) Idealized radiative forcing. Time evolution of the effective radiative forcing (ERF) to the CO2 concentration increased by 1% per year until year 70 (equal to the time of doubling) and kept fixed afterwards (white line). The likely and very likely ranges of ERF indicated by light and dark orange have been assessed in Section 7.3.2.1.
- (b) Emulated temperature response. Surface temperature response to the CO2 forcing calculated using the emulator with a given value of ECS, considering uncertainty in ΔF2×CO2, α, and κ associated with the ocean heat uptake and efficacy (white line). The likely and very likely ranges are indicated by cyan and blue, respectively. For comparison, the temperature response to abrupt doubling of the CO2 concentration is displayed by a grey curve.
The mean, likely and very likely ranges of ECS and TCR are shown at the right (the values of TCR also presented in panel b).
Further details on data sources and processing are available in the chapter data table (Table 7.SM.14).
