Scientists used a supercomputer to model interactions in the atmosphere. The table shows the predicted average global temperature of Earth compared to atmospheric carbon dioxide concentration, in parts per million (ppm), based on that model.

Which statement correctly describes the relationship between the data shown in the table?

A Higher carbon dioxide concentrations will likely coincide with a decrease in temperature.

B Carbon dioxide is the only factor that affects the average global temperature.

C Higher carbon dioxide concentrations will likely coincide with an increase in temperature.

D Average global temperature is a constant value and is independent of atmospheric carbon dioxide.

Higher carbon dioxide concentrations will likely coincide with an increase in temperature.
