Imagine if you could one day somehow triangulate a meteor impact causing that event by looking at the patten of how certain trees on certain geographic locations were affected. But might just be a volcano. Boring in comparison but not for the people that had to live through it. So after 2020, we know exactly what's going to happen if that goes down again, right? A third will deny it entirely (sun is fine, just a hoax, air was always that bad, get back to work).
