I think you can trace that weirdness all the way down to the act/omission doctrine underlying Judeo-Christian ethical systems; in most situations it is considered way worse to cause harm by action than by inaction. I do like the “we are already doing geoengineering” angle, it flips the narrative a bit. But I think people will still find the cases to be very different; at the end of the day nobody’s goal with emitting CO2 is climate change, it’s just a side-effect. Vs the explicit goal of (positive) climate change with geoengineering.
