In this talk, I will use the available data to discuss the possibility that erosion, weathering fluxes and sediment accumulation have remained constant over the last ten (or more) million years. Two important implications are: (1) global climate change may not change global denudation rates, because the nature and sign of landscape responses are varied; and (2) tectonic and climatic perturbations are accommodated in the long term by changes in landscape form. This work undermines the hypothesis that increased weathering due to late Cenozoic mountain building or climate change was the primary agent for the decrease in global temperatures.
