Carbon Dioxide is plant food. Earth is currently in a “CO2 famine”. The geologic record reveals that ice ages have occurred when CO2 was at 2000ppm to as high as 8000ppm. In addition, peer-reviewed studies have documented that there have been temperatures similar to the present day on Earth when carbon dioxide was up to twenty times higher than today’s levels. And, a peer-reviewed study this year found that the present day carbon dioxide level of 400ppm was exceeded – without any human influence – 12,750 years ago when CO2 may have reached up to 425 ppm.
It is thus good news that carbon dioxide levels have reached 400ppm and the greening of planter earth can continue. Read more:
