O2 is not the tail that wags the dog. CO2 is a trace essential gas, but without it life on earth would be impossible. Carbon dioxide fertilizes algae, trees, and crops to provide food for humans and animals. We inhale oxygen and exhale CO2. Slightly higher atmospheric CO2 levels cannot possibly supplant the numerous complex and inter-connected forces that have always determined Earth’s climate.
Increased CO2 levels are hardly something to fear. The current average level of CO2 in the air is 390 parts per million (ppm), well below the historical norm. Indeed, observes Morano,
Scientists note that geologically speaking, the Earth is currently in a ‘CO2 famine’ and that the geologic record reveals that ice ages have occurred when CO2 was at 2000 ppm to as high as 8000 ppm. 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.
