Just for the record, I haven't finished the paper so bear with me here.

I like the solar connection. It points to what I've been arguing for years: that the sun most certainly does play a role in climate here on Earth.

But this isn't a global warming thread.

The trouble is the correlation, while strong, hasn't actually been proven. We're in a period of low solar activity right now after a period of intense activity. The next several years could count as a natural test of this paper's theory.

Here's what's interesting about that. There is a persistent hypothesis that as far as I know has never been disproved: that low solar activity can trigger volcanic eruptions.

Yep. Combined with Napier and Clube's Taurid dust loading at this same time period. :)) (Sorry, had to throw that in there!)

Let's talk about the historical record. What do the historical chroniclers of the time say?

(Sorry, I just had to throw that in too!)
