A CO(2) greenhouse efficiently warmed the early Earth and decreased seawater (18)O/(16)O before the onset of plate tectonics
The low (18)O/(16)O stable isotope ratios (δ(18)O) of ancient chemical sediments imply ∼70 °C Archean oceans if the oxygen isotopic composition of seawater (sw) was similar to modern values. Models suggesting lower δ(18)O(sw) of Archean seawater due to intense continental weathering and/or low degre...
