What would happen if we put a giant glass tinted dome over each city? (lemdro.id)

In this scenario, we aren't trapped in the dome. There are openings and doors, so we can get out, cycle in fresh air, etc.

Is this a viable ~~solution to~~ way to avoid the effects of climate change? Would it be cooler in the dome? Would there be any negative repercussions? Would clouds form inside the dome? Could it rain in the dome? Would the rain be more toxic than usual because car fumes wouldn't dilute as well? Could outside lightning break the dome if it got struck? Would there be a single point in the dome that the sunlight would be directed to that everyone would just have to avoid, else they just burst into flame?

Sorry but I have so many questions about this. Apparently there was a show about the situation, but all I remember is that it wasn't very good. Hank from Breaking Bad was in it.

A large swarm of satellites, forming an adjustable solar shade, sitting around L1 for Earth-Sun is likely the best approach we would have. The swarm wouldn't be in a geosynchronous orbit, though, but instead a heliosynchronous one.

Wouldn't anything sizable enough to make a noticeable difference immediately act like a solar kite and be wisked off into space, L1 or not? They'd have to all have force sources(ionic engines or something) to counteract the force. I wonder how practical something like that would even be on something of that scale. Interesting to think about.

Whisked off into space by what, exactly?

Solar wind

Solar wind is not going to just yeet stuff around like that. It'll have some sort of impact, but it's not like, you know, actual wind.

For something that is positioned at L1 for an indefinite amount of time, with a large enough area to be effective as a solar shroud, it'll definitely have an impact.

That kind of shroud is effectively a solar sail without the ship attached.
