摘要

It is generally agreed that the level of atmospheric CO_2 on the time scale of millions of years is controlled mainly by a combination of degassing from the Earth's interior balanced by the uptake of CO_2 via the weathering of Ca and Mg silicate minerals. The CO_2 is converted to dissolved HCO_3~- during weathering, and this carbon is carried to the sea by rivers and precipitated there as Ca and Mg carbonate minerals.
