Historical events during which all liquid water on the surface of the Earth was frozen, the so-called snowball Earth (Kirschvink 1992; Hoffman et al. 1998), have occurred
at least three times, i.e., 2.43, 0.717, and 0.650 Gyr ago (Hoffman 2019).

* Although the trigger responsible for such an event is still under debate, including a hypothesis claiming a connection of the first event (the Huronian glaciation) to the Great Oxidation Event (Kirschvink et al. 2000)。

* we propose that the mechanism for snowball Earth could be wobbly passages of the solar system through spiral arms based on the hypothetical strong cooling effect owing to an increase in cloudiness seeded by an enormous influx of cosmic rays (Svensmark 2007). [https://arxiv.org/abs/2010.05962v1]
