Mate, I cut my teeth on Geology. I studied it at University some 34 years ago, albeit just up to second year level and I have been following developments since then.  I even worked in the geochemical field for about 10 years.

Paleoclimatology is not hairbrained, but once you get back as far as the Mesozoic, it becomes very speculative. The plethora of varying theories on the paleoclimate of the Mesozoic alone should be enough to convince you of that.

I'd love to see your calculations. What atmospheric concentration of carbonyl sulphide do you use to come to that (highlighted) conclusion?   (I have of course heard of the faint sun paradox, but there has been a fair bit of work carried out on sulphur isotopes in the last decade.)
