Do you feel similarly about freezing CO2 out of the air in the interior of Antarctica and burying it as dry ice? The natural temperatures are within spitting distance of the freezing point already (supposedly there have been occasional natural CO2 snows, although this is dubious because of the low partial pressure). Seems like it would be much less intrusive overall, although it would undoubtedly cost trillions to accomplish at scale.

Not the person you're replying to, but I think these two things are very different. I expect that the results of injecting substances into our upper atmosphere in large quantities are essentially impossible to model with high degrees of accuracy, and the consequences if things go wrong could be catastrophic. This freezing CO2 in Antarctica thing presumably does have some failure modes, but I imagine none of them are as comprehensibly terrible as if we were to screw up the atmosphere.
