AR6 WGI Report – List of corrigenda to be implemented The corrigenda listed below will be implemented in the Supplementary Material during copy-editing. CHAPTER 7 SUPPLEMENTARY MATERIAL Document Section Page :Line Detailed info on correction to make (Chapter, (based on the Annex, Supp. final pdf FGD Mat…) version) 7SM 7.SM.1.3.1 5:41 Replace “contrails, aviation induced cirrus aerosols,” with “contrails and aviation-induced cirrus, aerosols,” 7SM 7.SM.1.3.1 6.5 Replace “ACCMIP” with “AeroCom” 7SM 7.SM.1.3.1 6.13 to 6.16 Delete the sentence “Newer CMIP6 model results were not used as fewer model results are available and the complexity of aerosol schemes and internal mixing in these models makes attribution of aerosol forcing to precursors more difficult than in CMIP5-era models. » 7SM 7.SM.1.3.1 6:13 Replace “Newer CMIP6 model results were not used as fewer model results are available and the complexity of aerosol schemes and internal mixing in these models makes attribution of aerosol forcing to precursors more difficult than in CMIP5-era models” by “Section 7.SM.1.3.2 explains the rationale for choosing these coefficients.” 7SM 7.SM.1.3.2 7:53 After sentence “…to generate the time series of ERFari.” insert “These forcing contributions are based on modelling results from Myhre et al. (2013a), with scalings and uncertainty ranges for each component selected such that the total ERFari assessment of –0.3 ± 0.3 W m-2 is preserved. These estimates of per-species ERFari are independent of the headline assessments in Chapter 6, and differ particularly for BC (Section 6.4.2) where total BC ERFari is assessed to be +0.145 W m-2. The emulators in Chapter 7 are run with more positive ERF values for BC and more negative values for OC, SO2 and NH3 to preserve the assessed uncertainty range for total ERFari while maintaining a Gaussian uncertainty distribution for the forcing contribution from each species. As many aerosol precursors are co- emitted, the stronger best-estimate contributions per species used here offset each other and the time evolution and present-day values of total ERFari are broadly consistent between Chapter 6 and Chapter 7. It should be re-iterated here that the Chapter 7 values are not per-species assessments of ERFari and are used for the calibration and projection of climate in emulators.” 7SM 7.SM.1.4 8:14 Replace “4.36” by “4.35” 7SM 7.SM.1.4 10:4 Replace “4.36” by “4.35” 7SM 7.SM.2.2 11:36 Insert “SPM Figure 4b,” before “Chapter 1” 7SM 7.SM.2.4 12:53 Insert new subsection 7.SM.2.4: “7.SM.2.4 Supporting information for SPM Figure 4b A similar exercise was performed for the anthropogenic contributions to future warming shown in SPM Fig. 4b. As no natural forcing is included in this exercise, a long pre-industrial spin-up is not required and only the period 1750–2100 was run using the constrained two-layer model. As in Section 7.SM.2.3, 2,237 ensemble members are used, sampling the full assessed uncertainty ranges in effective radiative forcing and climate response. In these simulations, the baseline case is all anthropogenic forcing, with one component removed at a time and the differences in warming reported. Contributions to future warming are reported for CO2, other non-CO2 1 greenhouse gases (including ozone and stratospheric water vapour from methane oxidation), and other anthropogenic components. The latter category includes aerosols, land-use change, contrails and light-absorbing particles on snow and ice. The analysis is performed for SSP1-1.9, SSP1- 2.6, SSP2-4.5, SSP3-7.0 and SSP5-8.5. Temperature projections are reported for 2081–2100 relative to a 1850–1900 baseline.” 7SM 7.SM.7 39 In Table 7.SM.14: Row 1, Column 1: “Figure number / Table number / Chapter section (for calculations)” replace with “Figure number” 7SM 7.SM.1 39 In Table 7.SM.14: Row 2, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 39 In Table 7.SM.14: Row 3, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 39 In Table 7.SM.14: Row 4, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 39 In Table 7.SM.14: Row 5, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 39 In Table 7.SM.14: Row 6, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 39 In Table 7.SM.14: Row 2, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 39 In Table 7.SM.14: Row 4, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 39 In Table 7.SM.14: Row 4, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 40 In Table 7.SM.14: Row 1, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 40 In Table 7.SM.14: Row 2, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 40 In Table 7.SM.14: Row 3, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 40 In Table 7.SM.14: Row 4, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 40 In Table 7.SM.14: Row 5, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 40 In Table 7.SM.14: Row 6, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 40 In Table 7.SM.14: Row 2, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 40 In Table 7.SM.14: Row 4, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 40 In Table 7.SM.14: Row 5, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 40 In Table 7.SM.14: Row 6, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 46 In Table 7.SM.14: Row 2, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 46 In Table 7.SM.14: Row 3, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 46 In Table 7.SM.14: Row 5, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 46 In Table 7.SM.14: Row 2, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 46 In Table 7.SM.14: Row 3, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 46 In Table 7.SM.14: Row 5, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 47 In Table 7.SM.14: Row 3, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 47 In Table 7.SM.14: Row 5, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 47 In Table 7.SM.14: Row 7, Column 7: “https://github.com/chrisroadmap/ar6” replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.1 47 In Table 7.SM.14: Row 3, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 47 In Table 7.SM.14: Row 5, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 47 In Table 7.SM.14: Row 7, Column 6: Delete “(Smith et al., 2021)” 7SM 7.SM.1 48 In Table 7.SM.14: Row 1, Column 7: “https://github.com/chrisroadmap/ar6” 2 replace with “https://github.com/IPCC-WG1/Chapter-7” 7SM 7.SM.3 Table 7.SM.4 Add “5.00” Fourth row, fourth column (i.e ECS for upper assessed ranges) 7SM 7.SM.3 Table 7.SM.4 Add “2.53” Fourth row, fifth column (i.e ECS for lower CICERO- SCM) 7SM Update the Data Table with omitted data citations for climate model data. 3 Final Government Distribution 7.SM IPCC AR6 WGI 1 2 7.SM Chapter 7: The Earth’s energy budget, climate feedbacks, 3 and climate sensitivity - Supplementary Material 4 5 6 Lead Authors: 7 Chris Smith (United Kingdom), Zebedee R.
