Pretty much none of these are based in any sort of evidence though. This time we have concrete evidence that our environment is in a runaway loop past the point of repair.

This is not “I declare that Jesus will return in 184 months and then the rapture will happen” like pretty much every other prediction of apocalypse. This is not “the Mayan calendar runs out this year so the world is going to end”. This is not “the Bible said we’re going to have Revelations this year”. This is known fact.
