Estimate of mid-Pliocene Paleo-pCO2 for ODP Hole 130-806 (Table 1)
Three million years ago, prior to the onset of northern hemisphere glaciation, global mean temperatures may have been as much as 3.5 °C warmer than at present. We present evidence, based on the carbon isotopic composition of marine organic matter, that atmospheric CO2 levels at this time were on ave...
