The Antarctic ice-core plot of carbon dioxide (ppm) shows peaks and valleys at about the same times as the temperature plot has peaks and valleys, over 400,000 years. What can we conclude based on this fact alone?
A) There is a correlation between the carbon dioxide concentration and the average temperature.
B) Higher carbon dioxide concentrations cause higher global average temperatures.
C) Higher global average temperatures cause higher global carbon dioxide concentrations.
D) The carbon dioxide concentration is inversely related to the global average temperature.
