This paper uses arguments of geochemical mass balance to arrive at an estimate of the partial pressure of carbon dioxide in the terrestrial atmosphere very early in earth history. It appears that this partial pressure could have been as large as 10 bars. This large estimate depends on two key considerations.
WebSep 27, 2012 · In the 1950s, Nobel prize-winning American chemist Harold Urey proposed that the early atmosphere would have been largely reducing, based on the preponderance of hydrogen in the solar system (Urey 1952). Chemists use the terms “oxidizing” and “reducing” to describe the elements that carbon typically bonds with in an atmosphere.
