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

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.

I think it was in SuperFreakanomics where they explored the viability of releasing the equivalent to volcano smoke into the atmosphere to shade the earth. The research was based on earth cooling after certain types of volcano eruptions.

I think the scientist conclusion was that it was pretty viable but introduces way too many other issues. The biggest being, who gets to control the earth thermostat.
