[HTML][HTML] Climate and ocean circulation in the aftermath of a Marinoan snowball Earth
L Ramme, J Marotzke - Climate of the Past, 2022 - cp.copernicus.org
When a snowball Earth deglaciates through a very high atmospheric CO 2 concentration,
the resulting inflow of freshwater leads to a stably stratified ocean, and the strong …

Climate responses to the splitting of a supercontinent: implications for the breakup of Pangea
Reconstructing deep time climate often relies on a limited number of data points, which can
hinder inference of the large‐scale climate state. Here we use an Earth system model with …
