I have often argued that since CO2 is plant food it cannot be pollution. It merely causes an increase in plant life wherever the CO2 happens to be. IIRC there was a huge spike in ocean algae in the past due to high CO2 levels. The Earth wants to survive. It adapts to do so. It is not static as some would have you believe. It changes. Even when man comes in and screws everything up (c.f. Salton Sea) the ecology adjusts and rolls on. Even Chernobyl is teeming with life. It may be different than it was but life goes on. What is the likely cause of all this global warming? CFCs. What happens when we match the climate predictions to the actual results? This.
