Usage

Details

Atmospheric co2 data since the Jurassic taken from Mayhew et al., (2008, 2012) and derived from the GeoCarb-III model (Berner and Kothavala, 2001). The data are eported as the ratio of the mass of co2 at time t to that at present. The format is a dataframe with the two following variables:

age

a numeric vector corresponding to the geological age, in Myrs before the present

co2

a numeric vector corresponding to the estimated co2 at that age
