Aftermath of a snowball Earth
JA Higgins, DP Schrag - Geochemistry, Geophysics …, 2003 - Wiley Online Library
Using a simple 3‐box model of the ocean‐atmosphere system, we simulate the cycling of
carbon and strontium in the aftermath of a global glaciation. Model simulations include the …

CO2 levels required for deglaciation of a “near‐snowball” Earth
TJ Crowley, WT Hyde, WR Peltier - Geophysical Research …, 2001 - Wiley Online Library
Geologic evidence suggests that in the Late Neoproterozoic (∼ 600 Ma) almost all land
masses were glaciated, with sea‐level glaciation existing even at the equator. A recent …
