Longer Snowball Earth deglaciation could have driven multiple phases of sea level rise and fall

Snowball Earth defines periods of our planet's history when ice spanned the globe, even reaching the equator. The planetary-scale freeze is thought to have been driven by ice sheet expansion triggering a climatic tipping point that led to runaway ice-albedo feedbacks: the ice sheets reflected incoming solar radiation back to space, causing climate cooling and continued ice sheet formation.
