Impact of global cooling on Early Cretaceous high pCO2 world during the Weissert Event

Impact of global cooling on Early Cretaceous high pCO2 world during the Weissert Event

Modelling and sea surface temperature proxy data from the Weddell Sea document a 3–4 °C drop coinciding with the Early Cretaceous Weissert Event. Temperature data worldwide confirm a 3.0 °C global mean surface cooling, equivalent to a ~40% drop in atmospheric pCO2, favouring local polar ice.
