Figure 5.37 | Cumulative carbon dioxide (CO2) uptake by land and ocean carbon sinks in response to stratospheric sulphur dioxide (SO2) injection. Results are shown for a scenario with 50-year (2020−2069) continuous stratospheric SO2 injection at a rate of 5 Tg yr–1appplied to a RCP4.5 baseline scenario (GeoMIP experiment G4; Kravitz et al., 2011), followed by termination in year 2070. Anomalies are shown relative to RCP4.5 for the multi-model ensemble mean and for each of six Earth system models (ESMs) over the 50-year period of stratospheric SO2 injection (left-hand side), and over 20 years after termination of SO2 injection (right-hand side). Adapted from Plazzotta et al. (2019). Further details on data sources and processing are available in the chapter data table (Table 5.SM.6).
