Oh no it’s absolutely worse in the long term. We have the choice of being super-fucked or ultra-fucked. If we blast sulphur into the atmosphere we might get to enjoy one generation of having food and water (maybe).
Slowing things down would be putting the sulphur back in diesel and spraying it from jets in the upper atmosphere. Any reduction in pollution at this point will just accelerate warming as we lose the cooling effect from the particulates in the atmosphere.
Maybe if you were sitting sideways in the cockpit and did it very abruptly with the flight control computer disabled (only a few jets can even disable it). It’s the sustained G loading that makes you black out or red out.
