 The amount of aerosol you'd have to put into the stratosphere to cool things down, and you would try to do that in a sort of globally uniform way, is pretty tiny compared to the amount of aerosol that we're accidentally already dumping into the lower part of the atmosphere we call the troposphere. So while there are many potential risks of doing this so-called solar radiation management, I don't think it's going to have that much effect regionally on hurricanes.
