Yeah, as a mass extinction event it is. However, I figured that took longer to escalate than one year, so it wouldn't quite work when answering the question of worst year to be alive
Ah, yes, the timescales may differ. I've always wondered how the estimates of those work for these geological events, as in, how do we estimate the "one-year-damage" curve or something like that. You're most likely right that the K-T may have had a higher peak in this respect.
It's so weird to try to reason about deep time, isn't it? It just goes beyond human intuition due to it's scale.
Also, thanks to your comment I double-check out the wiki page for the Permian-Triassic Extinction Event[0], and meteors being the cause hasn't been ruled out yet as a potential cause, in which case it might still win out!
