Fig. 2: Changes in stratospheric temperature and age of air caused by SO2 or calcite injections for 2020 boundary conditions.

From: Injecting solid particles into the stratosphere could mitigate global warming but currently entails great uncertainties

Fig. 2

Left column: zonally averaged temperature anomaly compared to the reference run for SO2 (top row) or calcite (bottom row). Right column: corresponding anomaly of the age of air (AoA) in months. Dotted area: statistically significant within the 95% confidence interval (t-test). See Supplementary Fig. 5 for zonal mean wind, H2O and ozone anomalies for 2020 GHG and ODS conditions and Supplementary Fig. 6 for 2090 conditions.
