Well, I'm sure in a limited case it wouldn't be that dangerous. But yeah, regarding the nuclear detonations, that's why I think it would have to be a last resort. Like, last resort as in a situation where humanity is in danger of extinction or in making Earth mostly uninhabitable.
In that case we should adopt a more cavalier attitude toward nuclear weapons. If we allow at least one nuclear exchange between two nations we could help offset the effects of global warming for a good while longer.
