Short summary
Short summary
Industrial aerosol increases in Asia and reductions in North America and Europe in 1980–2020 influenced climate changes over the Pacific Ocean differently. Asian aerosols caused El Niño-like temperature patterns and slightly weakened the natural variation in the North Pacific, while reduced emissions of western countries led to extensive warming in middle–high latitudes of the North Pacific. Human impacts on the Pacific climate may change when emission reduction occurs over Asia in the future.

Short summary
Rapid reduction in atmospheric methane is needed to slow the rate of global warming. Reducing anthropogenic methane emissions is a top priority. However, atmospheric methane is also impacted by rising natural emissions and changing sinks. Studies of possible atmospheric methane removal approaches, such as iron salt aerosols to increase the chlorine radical sink, benefit from a roadmapped approach to understand if there may be viable and socially acceptable ways to decrease future risk.

Short summary
Anthropogenic aerosol (AA) emission has shown a zonal redistribution since the 1980s, with a decline in the Western Hemisphere (WH) high latitudes and an increase in the Eastern Hemisphere (EH) low latitudes. This study compares the role of zonally asymmetric forcings affecting the climate. The WH aerosol reduction dominates the poleward shift of the Hadley cell and the North Pacific warming, while the EH AA forcing is largely confined to the emission domain and induces local cooling responses.
