>Change my mind.
I have no interest in what you beleive.
However some readers may be interested in a couple of obvious points that spring to mind.
First up the source Ruddiman has a ten year more recent eddition
https://www.amazon.co.uk/Earths-Climate-Future-William-Ruddiman/dp/131915400X/ref=pd_lpo_sbs_14_t_0?_encoding=UTF8&psc=1&refRID=FNAJRPPHR87XAHQZCF0X
This will include a lot of work by the likes of Tripati et al 2009 that had significant refinements to Miocene CO2 and temperatures.
Secondly the sources cited predate Royer 2004 (and his more recent works including one about a year ago) that look at Phanerozoic coupling of CO2 and temperature. Its sort of a review piece in rather than new research but it shows the over all trend.
​
>Weathering fluxes are modified over time as changes occur in global temperature, continental size, position and relief, and land plant colonization. This includes incorporating solar radiation, due to the slow stellar evolution of the sun, and the CO2 greenhouse effect in general circulation model (GCM) calculations of global mean surface temperature and river runoff. Volcanic degassing is guided by the abundance of volcanics, seafloor spreading rates, and the carbonate content of subducting oceanic crust.
This is the changing luminosity of our star over time
​
It has increased at about 30%, this increase is non linear so the past couple of hundred million years are given at a heuristic of 1% per 100 million years. That is to say a graph of CO2 over times scales of billions of years, without mapping it against solar output is nonsense.
Another quick aside it mentions Ordovician climate but with sources from about 2007, Young 2010 has significantly updated our understanding of the evolution of CO2 and temperature during this period.
​
In short this appears to be very out of date, missing vital context and a bit of a mish mash of mixed papers trying to push a conclusion.
As always you mileage may vary and all corrections offered in good faith welcomed.
