Here is the problem with that graph. For the last few years we have been getting cooler. If the CO2 levels exploding means we are heating the earth, and we are the cause of most of the climate change, it's imposable to get colder (unless we have lowered the CO2).
If that graph is right, then the CO2 levels must have very little effect on global warming compared to other factors. That chart proves CO2 levels mean nothing (or almost nothing).
