Well... someone's right about Global Climate Change...
"Late Carboniferous to Early Permian time (315 mya -- 270 mya) is the only time period in the last 600 million years when both atmospheric CO2 and temperatures were as low as they are today (Quaternary Period )." (emphasis mine)
Looks like we’ll need to pump a lot more CO2 into the atmosphere just to make the environment more “natural”.
