 I was watching a documentary on YouTube about, they called it the world's worst year, I think it was 535 A.D. or somewhere in there, where worldwide famine, just social unrest, massive extinction-level events, and they had traced it back to a massive eruption at Mount Krakatoa. Mount Krakatoa, yes. So there's your particulate matter in the air kind of creating a veil. Maybe it's similar.
