I'm honestly too tired right now to correct the stupid of not understanding the original news story.... but fuck it, here's the short version:
sulfate particles, that are indeed considered pollutants, have a known property of reflecting solar radiation back into space. It's why they've been proposed as a geoengineering solution to global warming. It's why massive volcano eruptions can cause a decrease in temperatures for a while.
But unlike CO2, these particles have a limited time that they remain in the air. Meaning if you stop producing them, in this case as a consequence of manufacturing pollution, after not that much time, you're gonna notice a bit more solar energy making it to the planet surface.
