Abstract At the end of the Precambrian, the Earth was entirely covered by ice. Paleomagnetic evidence has revealed that glacial deposits had formed at the lowest latitudes. This happened twice, during the Sturtian and Marinoan glaciations.

Thin Ice on the Snowball Earth
2013Global ice-covered conditions during a Neoproterozoic snowball Earth seem inconsistent with the survival of eukaryotic algae. The presence of thin ice in the tropics remains a viable alternative to resolve this paradox. The simple method of McKay [2000] for computing ice thickness has been improved by considering separately a short wavelength interval (

Abstract Because of its high albedo, the Snowball Earth seemed inescapably frozen. However, volcanism progressively delivered CO2 in the atmosphere. The ice-covered lands could not provide a CO2 sink by atmospheric weathering. Therefore, the atmospheric CO2 content increased until a threshold when the extreme greenhouse effect resulted ...
