The sub-heading says that annual CO2 levels have little impact on the annual temperature change. Looking at this data objectively, it is very difficult to claim that there is any correlation between the changes of the CO2 concentration in the atmosphere and the changes in the surface temperature! This states the real lesson of the data better than the sub-heading of the graph does.
This is consistent with my understanding of the basic physics of the Earth's climate as I have discussed it numerous times. The effect of atmospheric CO2 is very, very small. It is probably actually a cooling effect, just as that of water vapor certainly is.
The changes in the temperature anomaly from one year to the next are the differences between a year's temperature anomaly and that of the next year from this data set.

Once again there is little reason to be concerned about the emissions of CO2 due to using fossil fuels. So why is the Obama regime, and his EPA in particular, claiming that carbon dioxide is a pollutant. Plants certainly do not think it is anything of the sort. Increased crops and natural vegetation provide us many benefits:
- Increased food supplies for people and livestock
- A decrease in arid land areas
- Moderation of day to night temperature variations
- Increased oxygen production
