Extended Data Fig. 1: Conceptual model for reverse weathering as a stabilizer of the long-term global carbon cycle and climate.
From: Reverse weathering as a long-term stabilizer of marine pH and planetary climate
Reverse weathering regulates atmospheric \({p}_{{{\rm{CO}}}_{{\rm{2}}}}\) through the establishment of a stabilizing feedback with marine pH (a pH thermostat). This feedback operates in conjunction with the silicate weathering feedback (dependence of chemical weathering and erosion on temperature and rainfall) to stabilize climate. A more potent reverse-weathering buffer, which is to be expected under high-silica Precambrian conditions, greatly strengthens the pH buffering capacity of oceans.
