Jurassic, 3 C warmer, CO2 1950 ppm, 60 million years ago, birds evolved

Pliocene, 3 C warmer, CO2 415 ppm, 4 million years ago, big sharks

Eemian, 3 C warmer, CO2 280 ppm, 125000 years ago, modern humans evolved

If anyone thinks today's climate can be considered normal, I would disagree completely.

I have to ask, how was the average global atmospheric temperature of the Jurassic calculated? For what time/date was the temperature calculated?

Same for the Pliocene.

Into the Night has already shattered any hope of relationship between atmospheric CO2 levels and really anything else.


p.s. - Can't you cite anything other than Wikipedia? You are begging for a summary dismissal of your entire thread.

IB STILL hasn't explained what Planck's Law means. Just more hand waving that it applies to everything and more asserting that the greenhouse effect 'violates' it.- Ceist
