What were CO2 levels in early and late Carboniferous, an what were mean levels? Who are the sources for these figures?

  • What do you mean under "who are the sources"? Do you mean who are these researchers who came up with these estimates, or do you mean what is the scientific basis for these estimations? – Ale..chenski Oct 12 '18 at 20:09
  • I have read that the Carboniferous was caused by the evolution of plant cellulose or lignin and fibres, and it took millions of years for microbes and animals and funghi to develop enzymes to dissolve it so it caused excess oxygen. Perhaps the co2 was caused by fires. – bandybabboon Oct 14 '18 at 02:41

Carboniferous CO2 levels may not have been unlike today's. Evidence for this is primarily from long term geochemical modeling work, as there are few direct proxies of sufficient age.

I can easily cite one source, as it's from my own paper, but please check the reference list for the other datasets. http://dx.doi.org/10.1016/j.chemgeo.2013.10.012 Phanerozoic CO2, fig. 5, p. 294
