Abstract

Geological records witness extensive glaciations in the late Ediacaran, ranging from ~580 to 560 Ma or younger. However, the explanation of maintenance for this regionally diachronous and globally continuous glacial epoch is still unclear. Here, using the Earth system model (CESM 1.2.2) and the revised weathering model, we demonstrate that the newly exposed regions with high weatherability from glaciated continents to ice-free tropics, controlled by true polar wander (TPW), could increase weathering rate to maintain uninterrupted late Ediacaran ice age, especially during 575–565 Ma. The atmospheric CO2 level would be
