It's Sulphur Dioxide. SO2. It's released from volcanoes when they erupt and is used in food preservation. It doesn't block a lot of visible light but it blocks infrared more effectively.
If you trust the models in the IPCC reports then when very large volcanoes erupt then there is a "detectable" 0.9F (0.5C) decrease in average temperature for a few months semi regionally afterwards.
It's highly likely that releasing this in the upper atmosphere will not have the same (utterly marginal) "effect;" however, it will contribute to acidified rain. Retarded^2.
The cooling is generally attributed to the dust raised into the atmosphere, which does block all the spectrum to an extent increased over normal. If SO2 blocks infrared light, it should cause an increase in surface temperature. But the point is for it to form sulfurous acid from humid air, which will condense into droplets.
The observational data is true, regardless of the IPCC models (which I mistrust). The association of cooling in the aftermath of volcanic eruptions is noted as historical events, in some cases causing the absence of a summer.
They have observed the negative effect from the reduction of SO2 in marine Diesel exhaust from merchant ships (fewer cloud trails), so the effect is plausible---but there would need to be a massive program to produce any meaningful effect.

Why would that be true?

The problem is, not always, because this is all based on ice core samples. And we have high level samples for which no recorded volcano exists leading to this climate gem:
High absorption coefficient of infrared light by water vapor (and CO2) is the basis of the "greenhouse effect", the scattering of infrared light which results in nearly half of it returning to the Earth surface from the sky. SO2 would presumably be part of it.
1816, "The Year Without a Summer," resulting from the titanic eruption of Tambora in the Indonesian archipelago. And from other large volcanic eruptions. No ice cores necessary. This is all on record. https://en.wikipedia.org/wiki/Year_Without_a_Summer All kinds of things can cause a broken leg. Increased clouds result in decreased albedo, resulting in lowered surface temperature.
Kind of funny when you come back at me echoing what I told you in the first place. (By the way, the USGS gets it wrong. SO2 creates sulfurous acid, H2SO3. You need sulfur trioxide, SO3, to get sulfuric acid, H2SO4.)
