The civilization that lived on thermal wells

I pose an assumption.  Intelligent live faces multiple extinctions via volcanic instability.  I base this on the resiliency of life to recover such that it always starts before the planet is geologically stable.

Let us assume we are that first species to survive the fate, locally. We have controlled the earths's crust to make it circular with  circular orbit. We use a thermal well system as a local control gyro for the equations of motion. A global well and pipe system, we move the hot spots of the earths crust to the cold spots.

There is an alternative elliptical orbit more stable to long term geological stability, even if it means we spiral a bit. The seasons become more uniform, ice line stable.  Pump in seawater, get steam out. CO2 is removed in the process. Something like the Cal via duct, a huge man made ocean river pumped deep into the cascade volcanic range. Followed by huge steam powered electrical generation. Bury the salts and carbons into the crust, create great freshwater storage ponds and lakes.

We cause another longer term problem, the earth no longer responds to solar perturbation, and will spiral downward, slightly.  Ultimately the longer term still implies planetary escape. Or we may look to a more elliptical system, one in which we expend more thermal energy shaping an elliptical orbit with short summers. Then we pay a wobble price, but we don't care, we have technology to respond fast enough in freezing and melting earth's crust. We can literally fly this baby by changing its shape= and expenseing the wobble cost.

Drill, drill, drill as lil Bush said.
