Fig. 4: Global temperature response to anthropogenic aerosol reduction and marine cloud brightening.

Spatial distribution of surface air temperature (SAT, K) changes due to (A,D) the changes in anthropogenic aerosols under SSP1-1.9 scenario, (B,E) marine cloud brightening (MCB) sea salt aerosol injection, and (C,F) the combined effect of anthropogenic aerosol changes and MCB sea salt aerosol injection from the fully-coupled simulations. The top and bottom panels show the changes in 2050 (average of 2045–2054) and 2095 (average of 2091–2100), respectively, relative to 2025 (average of 2020–2030). The stippled areas indicate results are statistically significant at the 95% confidence level based on the Student’s t-test.
