When people burn fuels, carbon dioxide is not the only gas released. Many other gasses are released as well. Some of these gasses tend to reflect light rather than absorb it. This actually [i]reduces[/i] the amount of energy absorbed by Earth, causing a cooling effect. It could be that any increase in the greenhouse effect due to human-produced carbon dioxide is offset by the cooling caused by the other chemicals associated with human activity.
