If temperature gets too low, we flick a switch and open one or more of the mirror windows to let in light.
I don't think we have the resources to do that though. Unless we started colonizing Mars and mining asteroids, tech that's almost a century away.
We could do it now. It's just expensive and we can't really be bothered.
I'd argue we should be colonizing the ocean beforehand anyway, as it'll allow us to experiment in the social structure of enclosed colonies, net us more wealth/resources in the meantime, develop tech usable in space colonization, and be far, far less dangerous.
(A broken colony base on mars is basically fucked unless they hold on for a year or so. A broken colony base in the ocean can be rescued if they can just hold on for a few hours.)
That allows us to work out the kinks.
Plus, development of undersea colonies would allow us to put funds into the industries necessary for space colonization. After a while, those lobbies will do the job for us.
Billion dollar industries pressuring the government to expand into mars and such.
Undersea colonization could also be the answer to renewable energy, with the undersea colonies being the major producers of electricity from thermal vents, and hydroelectricity.
