For one, the relative roles of eccentricity, obliquity, and precession in controlling glacial onsets / terminations are still debated.

I have also seen your comments on WUWT where I read about your ideas on the termination of the glacial periods from a low vegetation / high dust environment as a result of low CO2 levels at the glacial peaks, which seems very plausible to me.

Few people have read paleo - climatology text books, are aware of the glacial / interglacial cycle, are aware that the paleoclimatic record has unequivocal evidence of cyclic gradual changes and cyclic abrupt climate events, are aware that the abrupt climate change events such as the abrupt termination of the last 22 interglacial periods lacks an explanation, are aware that all of the past interglacial periods are short (roughly 12,000 years) and that they have ended abruptly, and so on.
