You are right that the similarity of the trend over a period of several years is not significant, and I would hope that few readers would take it seriously. But I also imagine that I can see in this (and a proper statistical study could be done to confirm or contradict this) that there ARE correlations in the short term. These are the more interesting.

Honestly, that graph doesn't make a lot of sense to me. You could tie so many things together in the same way, but that doesn't mean its true.

Statistically I can make a graph of any number of unrelated things and make them look related. As I told my stats 101 students over and over Correlation does not mean Causation.
