Faust Evidence for the Postconquest Demographic Collapse of the Americas in Historical CO2Levels 2006 14 .pdf application/pdf 6662 557 67 ABSTRACT: This article promotes the hypothesis that the massive demographic collapse of the native populations of the Americas triggered by the agricultural fields soon recovered by forests, which in due turn fixed atmospheric CO2 in significant quantities. This hypothesis is supported by measurements of atmospheric CO2 levels in ice cores from Law Dome, Antarctica. resulting from forest reclamation of abandoned agricultural fields in the Americas of the indigenous population of the Americas over forest sequestration to a reduction of atmospheric CO2. The area bears evidence of agricultural fields and their abandonment in preHispanic times: a strong expansion occurred during the so-called Yotoco period, Atmospheric CO2 measurements from the Law Dome ice core DSS (plotted with data from Etheridge et al. models, and taking into consideration that these climate sensitivities refer to equilibrium conditions, we can expect a global temperature change of –0.1 to –0.2 K, ./cache/work_uxxtdvwgwferfhhdsccsgir2wu.pdf ./txt/work_uxxtdvwgwferfhhdsccsgir2wu.txt
