I don't think that's an option when you have neighboring cities that are played by other people.

I believe your city will impact theirs and vice-versa.

Wait, so what happens if I build lots of nuclear plants then let them all melt down? Does that affect neighboring cities that other people are actually playing?

I believe it is designed to affect neighboring cities, yes. And this is basically what happens in real life... and then war.

Any idea how they are going to handle griefers then? I can't imagine they are just going to ban people who habitually don't take care of nuclear plants placed on the map's edge.
