Interaction between vegetation and Snowball phases in the late Proterozoic Earth
This study numerically demonstrates that the evolution of land vegetation was a critical factor in preventing subsequent Snowball Earth episodes by lowering continental albedo, thereby making global glaciation unlikely under current solar luminosity and CO2 levels even with equatorial continents, whereas the bare, high-albedo Rodinia supercontinent combined with lower solar output could trigger Snowball states at significantly higher CO2 concentrations.
