I recall one post on how Earth came out of a snowball, which explanation may be a possibility but then again there may be other explanations (eg., oceanic volcanos splitting in the ice and thereby releasing some water vapour, soot deposits changing albedo, even meteor collision — who knows given the lack of evidence).

Seems to me David's mistake is not noticing that the rapid events are internal to the climate system, not external; they may cause fast changes in albedo for example for a while; and they are modeled, see Dr. Bitz's work on Arctic sea ice, or any model including volcanos or Atlantic deep water currents etc..
