|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.

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
