Well, if people are still around in 3100 (I think they will be), and are not in a state of semi-savagery, then this may be the first time such an event is headed off. It's simple enough to scatter carbon black over vast tracts of Greenland and the Arctic Ocean to ratchet back up the amount of sunlight received if it falls off. So this "little ice age" scenario is susceptible to even a low-tech manipulation.

Fact is, there will be economic effects on Earth due to changes in solar output in almost any conceivable technological environment. So we may be able to stave off the temperature effects but that means less resources for other things and thus more competition for what resources remain.
History shows that climate has a huge effect on economic organization. Basically colder times require more centralized energy use. This tends to make for larger governments as well -- since govt. seeks higher tax revenues.
The last time we went from a cold period to a warming trend, about 1500 years ago, the Roman Empire fell. Greater economic self-sufficiency leads to more people who won't put up with the politicians' re-distribution schemes.
