Neither the trigger for the initiation, nor the reason for the ending of such phases, are well understood. Here we discuss some mechanical effects of the impact of asteroids 5\u201310 km in diameter on the Snowball Earth environment. An impact of this scale is the largest impact that is statistically predictable for 10\u201360 Myr time periods. The impact cratering itself (shock waves, impact crater formation) is not powerful enough to change the natural climate evolution path on Earth. However, the products of impact (mainly\u2014water vapor) can be quickly distributed over a substantial part of the globe, influencing the global circulation (e.g., facilitating cloud formation). It is a question for future studies to confirm if such an event (which is possible statistically during this interval) may or may not have influenced the global climate of the Snowball Earth, and\/or contributed to deglaciation.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Christian Koeberl, Boris A.
