| Summary: | The burning of biomass that often accompanies deforestation and other changes in land use is believed to be a major contributor to documented increases in the concentration of atmospheric CO{sub 2}. Using three models of carbon turnover in the atmosphere and ocean, we simulate changes in atmospheric CO{sub 2} that result from the addition of CO{sub 2} from industrial sources and terrestrial ecosystems disturbed by changes in land use. We simulate atmospheric response to different histories of terrestrial biospheric CO{sub 2} release, and we compare these simulations with the history of atmospheric CO{sub 2} obtained from ice core measurements and atmospheric monitoring stations. 63 refs., 12 figs., 1 tab.
