Description:

Data for Figure 9.22 from Chapter 9 of the Working Group I (WGI) Contribution to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6). Figure 9.22 shows simulated versus observed permafrost extent and volume change by warming level. --------------------------------------------------- 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: Fox-Kemper, B., H.T.

Estimates of current permafrost extents based on physical evidence and reanalyses are indicated as black symbols – triangle: Obu et al. (2018); star: Zhang et al. (1999); circle: central value and associated range from Gruber (2012). Further details on data sources and processing are available in the chapter data table (Table 9.SM.9) --------------------------------------------------- Notes on reproducing the figure from the provided data --------------------------------------------------- The panels were plotted using Python and shell scripts (BASH files) - code is available via the link in the documentation. --------------------------------------------------- Sources of additional information --------------------------------------------------- The following weblinks are provided in the Related Documents section of this catalogue record: - Link to the figure on the IPCC AR6 website - Link to the report component containing the figure (Chapter 9) - Link to the Supplementary Material for Chapter 9, which contains details on the input data used in Table 9.SM.9 - Link to the data and code used to produce this figure and others in Chapter 9, archived on Zenodo. - Link to the code and output data for this figure, contained in a dedicated GitHub repository.
