None of the geoengineering solutions address the other major issue with our fossil fuel usage, which is ocean acidification. Even if we could just lower the temperature, lots of the CO2 pumped into the air gets absorbed into the oceans, like in a bottle of soda, making it more acidic. When this happens, it makes it harder for all the life at the bottom of the food chain to form, causing a mass die off at the base. If things get bad enough It could lead to the collapse of the food chain and we would just starve to death.
Excellent point. And if we put up a big space mirror, and then solve the CO2 problem to get ocean PH back to normal, now our lower solar incidence plus normal greenhouse gas levels will equal temperatures way too cold.
Imagine Keppler syndrome kicks in as a result of building it, and it causes an ice age down here and we lose contact with it and can’t move it.
Now we’re an ice ball with a sky cage we can’t escape.
