My impression was that stratospheric aerosol injection has been kept out of the public consciousness deliberately. If the public discussed it now, they’d learn quickly about things like termination shock, and the calculable consequences to weather systems depending on where the sulphur is injected (eg Inject over Norway and mess up el Nino), and come to the conclusion that it’s a pretty undesirable option. If, however, it’s left to the last minute, fossil fuels can continue, and then use this as a “last resort” card.
