Chapter 7 of the Working Group I Contribution to the IPCC Sixth Assessment Report - data for Figure 7.6 (v20220721)
Abstract
Data for Figure 7.6 from Chapter 7 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6).
Figure 7.6 shows the change in effective radiative forcing (ERF) from 1750 to 2019 by contributing forcing agents (carbon dioxide, other well-mixed greenhouse gases (WMGHGs), ozone, stratospheric water vapour, surface albedo, contrails and aviation-induced cirrus, aerosols, anthropogenic total, and solar).

List of data provided
---------------------------------------------------
This dataset contains:
Change in effective radiative forcing (ERF) from 1750 to 2019 by the following contributing forcing agents:
- Carbon dioxide
- Other well-mixed greenhouse gases (WMGHGs)
- Ozone
- Stratospheric water vapour
- Surface albedo
- Contrails and aviation-induced cirrus
- Aerosols
- Anthropogenic total
- Solar
Solid bars represent best estimates, and very likely (5–95%) ranges are given by error bars.
Non-CO2 WMGHGs are further broken down into contributions from methane (CH4), nitrous oxide (N2O) and halogenated compounds.
Surface albedo is broken down into land-use changes and light-absorbing particles on snow and ice.
Aerosols are broken down into contributions from aerosol–cloud interactions (ERFaci) and aerosol–radiation interactions (ERFari). For aerosols and solar, the 2019 single-year values are given (Table 7.8), which differ from the headline assessments in both cases. Volcanic forcing is not shown due to the episodic nature of volcanic eruptions.
Further details on data sources and processing are available in the chapter data table (Table 7.SM.14)
