Beyond a hidden doorway a guarded elevator dropped them to the terraformer room at the center of gravity.

Terraformers call for a physical assault on such conditions.

At Geolab, Joaquim studied plugs that had been drilled from the Martian North Pole before it had been melted with an orbiting mirror… a strategy that terraformers hoped would chain-react into a greenhouse effect.

He always had clear skies, and, despite the best efforts of the terraformers, they would remain that way for the next few generations.

It was, in fact, the Oceanus Borealis that some terraformers talked about—but buried, deeply buried, and mostly frozen, and mixed with regolith and dense fines…

Even if all the technicians and Terraformers left, where would that leave the natives?

They're exploitationist. They want to rape the ecology so much, they might as well go live with the terraformers in the cities.

During their absence, the terraformers had transformed a hundred and twenty worlds into virtual Edens.

Here then was an attempt to allow a terraformer to create something not quite so homogeneous as many worlds in the Polity.
