Interaction between vegetation and Snowball phases in the late Proterozoic Earth
Silva, Laura
Between 2.4 and 0.6 Gy ago, our planet underwent several episodes of global glaciations, including the “Snowball Earth” case that ended 635 My ago. Causes of this last Snowball event presumably included a decreased greenhouse gas concentration and high continental albedo, both associated with the passage of the super-continent Rodinia at equatorial latitudes. When large continental masses are in equatorial regions, silicate weathering is enhanced, leading to decreased atmospheric CO 2 concentrat
