 Abstract: The sensitivity of the global river-borne flux of Ca2+ to atmospheric PCO2 was obtained from model simulations under the assumption of saturation of CaCO3. The response was subdivided into contributions from changes in runoff, temperature and partial CO, pressure and these were then used to parameterize the different direct and indirect effects of a changing climate on carbonate weathering and equilibria. The parameterizations are comparable/compatible to those of Walker et at. (1981) for silicate weathering, but are taken directly from models demonstrating the potential of this approach in weathering studies. [References: 10]
