But did not debris from the Taurid stream lead the the worldwide cataclysm 12,800 years ago? I’ve read debris from the Taurid stream could happen at any time the earth is exposed to that stream
The megafauna extinction at that time has been attributed to a one-time debris stream from a supernova. In a way though, it’s more comforting to attribute these things to something predictable and cyclical.

That’s said to be the gist of this paper:

I haven’t been able to make sense of it yet (not an astronomer/astrophysicist), but the theory is that around 2030 the Earth’s orbit will pass through a denser section of the debris field that produces the Taurid meteor showers, leading to some significant meteor impacts.
