Hopefully—if we have enough of a civilisation at the time. Reglaciation seems likely to only really be a threat after a major disaster or setback—I figure. Otherwise, we can just adjust the climate controls. The chances of such a major setback may seem slender—but perhaps are not so small that we can afford to be blazee about the matter. What we don’t want is to fall down the stairs—and then be kicked in the teeth.
If reglaciation starts, could it be stopped by sprinkling coal dust on some of the ice?
