Yannick Donnadieu and I have a paper coming out in EPSL in a few months where we study runoff changes throughout the Cretaceous, and find a very strong effect of the paleogeography, which can be stronger than the effect of CO2.

Rather than questioning the primary role of the atmospheric CO2, our modelling results allow us to put forward that the atmospheric CO2 is not the whole story and that, owing to the overwhelming effect and interplay between the paleogeography, the water cycle and the seasonal response, the climate system may undergo subtle climatic changes (as the 4 °C global warming simulated here between the Aptian and the Maastrichtian runs).

Petroleum geologists tend to be sedimentary geologists and sedimentary geology is essentially a combination of paleogeography and paleoclimatology.

... unless one examines snowball earth cycles, or considers the impact of historical changes in solar radiance and paleogeography on surface temperature.

This geographic distribution of anoxic conditions points towards the importance of paleogeography, basin restriction, and nutrient fluxes as key controls on the occurrence of extreme deoxygenation.

The model was initialized with Late Permian paleogeography and 10 × pre-industrial pCO2 level.

The spread of anoxia and euxinia differ between OAEs on their regional distribution as a consequence of paleogeography.

In such models, plate tectonics would evolve with a complete history of vertical motions, sea - level change, and paleogeography (e.g., Gurnis, 1992).
