Low sunspot - high snowfall correlation

[Cougar]

The data produces a fairly strong correlation between a low number of sunspots and a greater than average snowfall (or at least a lower average temperature). So the correlation is there, but I've not seen a definitive explanation as to the actual causation. That is, WHY does the number of sunspots have this effect?

This NASA webpage discusses possible relationships between sunspots/solar activity and weather/climate. Effects may be to both temperature and precipitation, so that might affect snowfall.

But I'd like to actually see this correlation, and see how strong it really is. And is it to total planet-wide snowfall, or something more regional, or what?

In the old days the sales of furs and pelts in North America and Canada correlated with sunspots, maybe they still do, it was thought to be because of rainfall and snowfall.
