I've been away from my computer, so a belated thanks for that link to the Stanford site. I was very intrigued by the roughly contemporaneous events cited by Thompson, and your link is right on topic.

As for those events having been caused by the onset of the Bronze Age (per your post #21), what could be clearer?

Nature, good; humans, bad. Bad humans...bad, bad humans!
