|today's climate compared to those of Jurassic, Pliocene, Eemian, and why today is not normal31-12-2015 01:28|
|Tai Hai Chen★★★★☆
|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.
