Feedbacks between weathering and atmospheric CO2 over the last 100 million years.

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

In an attempt to develop the formulation for weathering in long-term carbon cycle models, equations are drawn for calculating various possibilities of a CO2-productivity feedback upon weathering. Results of an analysis of the dependence of weathering rate on T and CO2 P, the connection between CO2 P in the atmosphere and in soils, the effects of a variable terrestrial biosphere on weathering, and other effects demonstrate the capacity of the terrestrial biosphere for moderating changes in climate and CO2 P and delineate the limitations to the strength of the CO2-productivity feedback functioning through the direct effects upon soil CO2. -M.S.
