Once again Koan... you are not even close. Permian age was 290 million years ago. However, one report I found states 400 ppm was typical of the Pliocene atmosphere some 3 million years ago. In that ancient 400 ppm world, sea level is estimated to have been 10 to 40 m higher than it is now ecology.com Why didn't your great extinction occur back then? After all, Humans were busy evolving from chimpanzees during that period. According to "End of World is Here" alarmists like yourself, most life on the planet should have been destroyed.
