"But “terraforming” is an anachronism in the present. Glaciers-to-grassland should require heavy future tech, maybe weather control."
I agree that the idea of glaciers becoming grasslands is unrealistic. But I've always conceived this not as the LAND changing, just what it PRODUCES. The grasslands don't really become hills which you can mine. Instead, your engineers work intensively on the grassland so that it produces less food, but much more material for building stuff.
