Am not much up to speed with the "snowball Earth" theories but apparently the paradigm has been that there was a very abrupt global warming from that state to one supporting the relatively high variety of pre-Cambrian life. This is now challenged by Greg J. Retallack of the University of Oregon, a specialist on the Ediacaran fossils:

I googled the title and got a few hits but so far they all lead back to the abstract and thence back to the original article. I'll keep looking.

I had thought some fairly active volcanism had an effect on breaking the freeze.
