Short summary
This study investigates the coupling of climate and the carbon and hydrologic cycles in Asia ~ 113 million years ago to provide a more complete continental perspective on a dynamic climate interval associated with global ocean anoxic events. We find relatively cool conditions and a close coupling between the amount of CO2 in the atmosphere, air temperature and rainfall in Asia. To quantify these shifts, chemical measurements from continental soils which formed during this interval are utilized.
