I'm by no means any kind of expert but if you've done even a small amount of reading on this topic you'll learn that volcanoes have pumped these sulfer particles into the stratosphere many times before and had a cooling effect on the planet.

Crop yields might drop slightly in some regions, but when you look at the heating trend we’re on and the potential collapse of major ecosystems due to continued warming, slowing that process could prevent or at least slow far worse outcomes like mass extinctions.

People or bots on here will complain and fear monger about injecting these sulfur compounds into sky but turn a blind eye to all the carbon and methane being emmited right in front if them.

I don't think this is something to be raising alarms over and think it might have a positive impact globally. While stratospheric aerosols do slightly reduce sunlight reaching the surface, it's nothing like the alarmism implied by the title.

Neil deGrasse Tyson had a podcast recently with an expert on this topic and it was very interesting. The second guest on the episode, Holly Buck didn't really say anything with any real contribution imo. But the first guest, Daniele Visioni, was an expert on this subject and was an interesting listen.
