    "abstract": "Data for Figure 7.11 from Chapter 7 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6).\r\n\r\nFigure 7.11 shows the temperature dependence of the feedback parameter, α (W m–2 °C–1), as a function of global mean surface air temperature anomaly relative to pre-industrial, for ESM simulations and paleoclimate proxies. \r\n\r\n---------------------------------------------------\r\n How to cite this dataset\r\n ---------------------------------------------------\r\n 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:\r\nForster, P., T.

The light blue shaded square extends across the assessed range of α (Table 7.10) on the y-axis, and on the x-axis extends across the approximate temperature range over which the assessment of α is based (taken as from zero to the assessed central value of ECS; see Table 7.13). \r\n\r\nFurther details on data sources and processing are available in the chapter data table (Table 7.SM.14).\r\n\r\n---------------------------------------------------\r\n Data provided in relation to figure\r\n ---------------------------------------------------\r\n Data provided in relation to Figure 7.11:\r\n \r\n - Data file: Figure7_11.csv\r\n\r\nESM stands for Earth System Model.\r\nGSAT stands for Global Surface Air Temperature.\r\n\r\n ---------------------------------------------------\r\n Notes on reproducing the figure from the provided data\r\n ---------------------------------------------------\r\nThe data provided is the output data of the figure which can be used to reproduce the figure.
