In the last few years other researchers using different climate models have found similar, but not identical, results. In general, though, it appears that the more explicitly the study represents the ocean physics in the model ... Webb[1] Modeling studies of the Neoproterozoic snowball Earth offer two variations for snowball conditions, the original “hard” snowball Earth where the ocean is completely covered by sea ice, and an alternate slushball Earth or “soft” snowball, where there is an equatorial oasis of open water. We use the University of Victoria Earth System Climate Model to show that … rd the
