CenoCO2

Code and data for Baysian timeseries models of Cenozoic pCO2 and temperature published by the CenCO2PIP Consortium.

data/

Data used in analyses.

  • 230902_proxies.xlsx Multiproxy paleo-CO2 data
  • Hansen13Russell.csv CO2 reconstruction from Hansen, et al. (2013)

  • 4_MainPlots.R Plotting for main manuscript
  • 5_SIPlots.R Supplemental information plotting
  • 6_OtherPlots.R Plotting for presentations and press
  • Helpers.R Functions used in other scripts
