This thesis presents a set of model studies of climate interactions with terrestrial rock weathering using the University of Victoria Earth System Climate Model (UVic ESCM); several different sets of weathering parameterizations are investigated within the context of two very important periods of Earth's climatic history. Firstly, we examine the importance of the rock weathering feedback mechanism during the last deglacial period (ca. 16,000 – 4,000 BCE) with four box-model parameterizations of terrestrial weathering. The deglacial climate change in the model was driven by changes in orbital parameters, prescribed atmospheric CO2 variability, and prescribed removal of continental ice sheets. Over the course of the 12,000-year simulation ...
