Fig. 4

Time series and linear trends (per 50 yr) of 5-yr mean annual AI anomalies over the globe (a), NH (b), and SH (c) for CMIP6 simulations. The ensemble means of historical ALL simulations are indicated with solid grey lines. The ensemble means for original future projection are given in dark blue and red solid lines for SSP3 − 7.0 and SSP5 − 8.5 ensembles, respectively, with blue and red shading represent the 5–95% ranges. The dashed lines indicate the corrected AI anomalies using the ALL scaling factors from 1-forcing analyses. The vertical solid and dashed bars show the trend uncertainty spread of original and corrected AI anomalies for SSP3 − 7.0 and SSP5 − 8.5 ensembles as labelled, respectively, with the dots indicating the mean values.
