Its a far more valid conclusion with statistical data to back it up. The atmosphere tends to go in patterns and cycles, this is a scientific fact. It's reasonable to conclude that when statistics indicate a certain pattern produces certain outcomes it's worth looking in to.
After all, this is how seasonal forecasting is done even though this is in its infancy. Large scale patterns like El Niño's generally correlate with wetter patterns in this area and a better chance for cold weather. There are various other factors that affect it too but that's just one example. What Ron posted is an interesting correlation that is worth looking further into. He actually took the time to do research and back up his statements with statistical analysis, if you're going to criticize it you should come up with some facts to indicate otherwise. Just my 2 cents.
