The snowball Earth hypothesis: testing the limits of global change
PF Hoffman, DP Schrag - Terra nova, 2002 - Wiley Online Library
The gradual discovery that late Neoproterozoic ice sheets extended to sea level near the
equator poses a palaeoenvironmental conundrum. Was the Earth's orbital obliquity > 60 (…
