[en] The role of continental weathering in the global carbon cycle is presented, focussing on the CO2 consumption and bicarbonate production rates. The different effects of silicate and carbonate weathering are worked out to derive constraints that the combined carbon and alkalinity
budgets have to fulfil. The influence of variations of continental weathering on atmospheric CO2 on glacial-interglacial time scales are analysed and illustrated with results from sensitivity tests carried out with the ocean carbon cycle model MBM-MEDUSA.
