A link to the code to plot the figure archived on Zenodo is provided in the Related Documents section of this catalogue record. --------------------------------------------------- List of data provided --------------------------------------------------- This dataset contains: - (a) Equilibrium climate sensitivity (ECM) estimates. Assessment methods: - Process understanding - Instrumental record - Paleoclimates - Emergent constraints - Combined assessment - CMIP6 ESMs - (b) Transient climate response (TCR) estimates. Assessment methods: - Process understanding - Instrumental record - Paleoclimates - Emergent constraints - Combined assessment - CMIP6 ESMs Assessed ranges are taken from Tables 7.13 and 7.14 for ECS and TCR respectively. Note that for the ECS assessment based on both the instrumental record and paleoclimates, limits (i.e., one-sided distributions) are given, which have twice the probability of being outside the maximum/minimum value at a given end, compared to ranges (i.e., two-tailed distributions) which are given for the other lines of evidence. For example, the extremely likely limit of greater than 95% probability corresponds to one side of the very likely (5–95%) range. Best estimates are given as either a single number or by a range represented by a grey box. CMIP6 model values are not directly used as a line of evidence but presented on the Figure for comparison. ECS values are taken from Schlund et al. (2020) and TCR values from Meehl et al. (2020); see Supplementary Material 7.SM.4. 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 7.18: - Data file: ecs_for_faq.csv - Data file: tcr_for_faq.csv Data is also provided in xlsx format, which is the format used by the plotting script linked in the Related Documents section.
