Scientific paper

Several scenarios for prevascular plant weathering are presented. The rise of vascular plants is examined in order to determine how levels of atmospheric CO2 could have been affected. It is concluded that in order to prohibit unreasonably high levels of atmospheric CO2, weathering during the Precambrian and early Paleozoic must have taken place under essentially closed-system abiotic conditions (linear feedback) or via strong regulation by primitive biota.
