My handy heuristic for headlines like this: Is it a scary new trend that means something or did other factors suppressing its natural emergence decline? Or is it a matter of observation?

A recent real-world example was the detection of two different objects entering the solar system. The naive speculation was "they came on the same plane, so they must be alien!" But the reality is more mundane: the new detection method that found them, while flexible, started by looking at that plane. So of course both objects it detected were on that plane.
