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.

Global Warming: The preferred religion of the scientifically illiterate.

Ceist - I couldn't agree with you more. But when money and religion are involved, and there are people who value them above all else, then the lies begin. - trafn

You are completely misunderstanding their use of the word "accumulation"! - Climate Scientist.

The Stefan-Boltzman equation doesn't come up with the correct temperature if greenhouse gases are not considered - Hank

:*sigh* Not the "raw data" crap. - Leafsdude

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
