It's not "impending doom." It's a cycle. That means that there are years of drought, and years of good rain, and this fellow might have a useable way to predict which is which. It helps in planning crops, water useage, and other activities. The nice thing about cycles is, just wait awhile, and it changes. It's not "doom."

That is a FR "running joke" graphic.

Perhaps if you'd read it in context of the post to which it was a *reply*, you'd have seen that.

If nothing else, my advice to Google 'metonic cycle' should've been a tipoff to the sarcasm, therein.

This guy is simply 'discovering' what's been known by "primitives" for a very long time.
Ancient cultures have been using the metonic cycle to "predict" agricultural trends for millennia.

For instance, part of the arrangement of Stonehenge keeps track of the metonic cycle.
