The incompatibility of ice-core CO2 data with reconstructions of biotic CO2 sources

Abstract
Analyses of the compatibility between postulated releases of biotic carbon and changes in atmospheric CO2 concentration must properly consider the history of changes in each quantity. A history of atmospheric CO2 changes obtained from ice-cores is compared to a history of biotic CO2 releases obtained from ecosystem modelling. It is shown that these two records are incompatible with any linear time-invariant model of oceanic uptake of CO2. DOI: 10.1111/j.1600-0889.1987.tb00102.x
