Actually, what was being predicted 50 years ago when I took an astronomy course, was that in the next few years one of the periodic sun cycles, the 88 year one, would have us seeing drought conditions like the dust bowl/depression years. Incidentally, have you seen the Phoenix dust blows?
The thing about natural cycles is they’re actually artificial, because they’re constructed to try to make something which is essentially random into something basically predictable and repeating; IOW, they’re not cycles anyway. :’)
The philosopher Hume asked the question to the effect, is it more likely that nature sometimes runs out of its course, or that human testimony is fallible?
It was meant as a rhetorical question, but the actual answer is, what we regard as the course of nature *is* human testimony.
