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

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.

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.

本数据集为政府间气候变化专门委员会（Intergovernmental Panel on Climate Change, IPCC）第六次评估报告（Sixth Assessment Report, AR6）第一工作组（Working Group I, WGI）第七章图7.8的配套数据。图7.8展示了1750年至2019年归因后的全球地表气温变化（Global Surface Air Temperature, GSAT），该结果基于两层模拟器（补充材料7.SM.2）生成，采用本章推导的有效辐射强迫（Effective Radiative Forcing, ERF，见图2.10）作为强迫场，并将气候响应约束至跨章节专栏7.1中所述关键气候指标的评估区间内。

--------------------------------------------------- 数据集包含内容 ---------------------------------------------------
本数据集包含：基于两层模拟器（补充材料7.SM.2）生成的1750年至2019年归因后全球地表气温变化（GSAT），该数据采用本章推导的有效辐射强迫（ERF，见图2.10）作为强迫场，并将气候响应约束至跨章节专栏7.1中所述关键气候指标的评估区间内。
气温贡献组分如下：
- 二氧化碳（carbon dioxide, CO₂）
- 甲烷（methane, CH₄）
- 一氧化二氮（nitrous oxide, N₂O）
- 其他混合温室气体（well-mixed greenhouse gases, WMGHGs）
- 臭氧（ozone, O₃）
- 气溶胶
- 其他人为强迫
- 总人为强迫
- 太阳强迫
- 火山强迫
- 总强迫
本次展示的结果为包含2237个成员的集合的中位数，该集合覆盖了强迫与气候响应的不确定性（部分组分的2019年最优估计与不确定性见图7.7）。阴影不确定性带表示极有可能（5%~95%）的区间。关于数据来源与处理的更多细节可查阅本章数据表（表7.SM.14）。
