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?

The fact that the Antarctic ice-core plot of carbon dioxide and temperature have peaks and valleys that occur at the same time suggests that there is a correlation between the two variables. However, it does not necessarily provide evidence for causation in either direction, so we cannot conclude A or B. The fact that the peaks and valleys occur at the same time suggests that the variables are related, but we cannot determine the exact nature of that relationship without additional evidence.
