STUDY NOTES: Multiproxy paleo-CO2 data from Kowalczyk et al. 2018, contributed to the Paleo-pCO2 Database.
ABSTRACT SUPPLIED BY ORIGINATOR: Proxy estimates of atmospheric CO2 are necessary to reconstruct Earth's climate history. Confidence in paleo-CO2 estimates can be increased by comparing results from multiple proxies at a single site, but so far this strategy has been implemented only for marine-based techniques. Here we present CO2 estimates for the well-studied early Paleocene Castle Rock site in Colorado using four paleobotanical proxies. Median estimates range from 470 to 813 ppm, demonstrating fair correspondence. The synthesis yields a median of 616 ppm (352-1110 ppm at 95% confidence), considerably higher than previous early Paleocene CO2 estimates (~300 ppm). Ash bed geochronology by the high-precision U-Pb method places the Castle Rock assemblage at 63.844 ± 0.097 Ma (fully propagated 2sigma error). When these results are placed into the broader context of other Cenozoic CO2 estimates from plant-gas-exchange approaches and coeval estimates of global mean surface temperature, a pattern emerges of an Earth system sensitivity around 3C per CO2 doubling during the Paleocene and Eocene, a time with little land ice, then steepening to >7C after the Eocene once land ice was present on Antarctica.
Purpose Records of changes in solar irradiance, volcanic aerosols, atmospheric trace gases, and other properties thought to influence climate in the past.
