I was reading some material on Roman History up to the failure of Rome in the 500s AD. It seems there were quite a lot of pandemics besides the 2 or 3 famous ones, particularly as the weather and growing conditions appeared to get worse not long after 200 AD.
My son and I were recently talking about whether the monster explosion recently of the Sunda volcano would affect our weather. I Googled and found that there would only be about 2% of the amount of ash as produced by I think they said Pinitubo, so not much to worry about. This caused by it being an explosion in water and thus not a lot of dry ash.
Ergot poisoning would explain the recent rise in violent “protests” as well as the current rise in violent deaths. Ergot poisoning could also explain Russia’s psychotic perception of a non-existent threat from Ukraine.
