We probably can't prevent another ice age. If it doesn't come on suddenly we might be able to do so. Massive burning of fossil fuels, using some of that energy to release CO2 and other greenhouse gasses from other sources. If we have centuries we could even put in place large object in space to reflect extra light on to the earth. There are other ideas that could be tried as well. Of course all of that (esp. the astronomical engineering part) would be expensive, and also it could have unpredictable consequences in other ways (for example ocean acidification might be a somewhat exaggerated problem, but if we were deliberately trying to produce as much CO2 as possible...) , all while using a lot of important resources. And there is always a chance that the prediction that started the effort was wrong, so we warm things up too much instead of just countering an ice age. The existing understanding of climate isn't solid enough to make reliable predictions.
