Due to acid rain, countries lowered SO2 emissions from industry and power plants. But SO2 is also a coolant via cloud-seeding aerosols. See Glen Peters' tweet: globally -0.5°C from 2010-2019. A very short lifetime of mere days means, SO2 molecules cool only locally, while methane and CO2 heat all.

SO2 is emitted by burning coal and ship fuel, & in #volcanism.
The other major coolant NOx, also short-lived with regional not global direct forcing, is emitted by burning fossil fuels eg in cars, and lightening storms & biomass burning.
So when our emissions drop, local heating goes up: " #TerminationShock".

When I say "local heating goes up", I should add that via wind and land-atmosphere and ocean-atmosphere interaction, this local heating also has global repercussions. Eg., wind drives the warm-er air parcel across the globe. So a warmer China and Japan who ditched SO2 and NOx, also heat the #Pacific.

Lowering SO2 and NOx while N2O (fertilizer), CH4 and CO2 emissions still rise is rather stupid.
