Nicolas Kokel Wrote:Put in a different way, if mankind were to make a gigantic bonfire and burn all the plants and trees in one go, it would add only about 70 ppm of CO2 to the atmosphere and the total atmospheric CO2 would become about 480 ppm.

The ice cores drilled at Vostok Station in Antarctica indicate that at the height of the last major glaciation event, 18,000 years ago, CO2 dropped to roughly 180 ppm (left lower peak on the graph here below). This is only 30 ppm above the level of starvation for most plant species, which is 150 ppm.
