- outworlder 7y agoYou are very optimistic if you are talking about "cities" in that timeframe.

Placing reflectors in a lagrange point to control the amount of solar energy reaching Earth with be child's play. Even once it enters the red giant phase, it'll be several hundred million years before it consumes Earth.
