536 was considered the worst year ever, to be alive.

Kinda puts 2020 into perspective.

> Ask medieval historian Michael McCormick what year was the worst to be alive, and he's got an answer:

This seems likely to be biased by asking a "medieval historian". Are we surprised that his answer came from the period he studies?

there were also the 4.2 kiloyear event (2200BC) that caused the collase of the old kingom and akkadian empire. [1] the bronze age collapse around 1200BC is now also partly explained by a climate event, that drove the sea people into warmer regions [2]; the black death in the middle ages may also have something to do with climate [3]; It looks as if every millenium there is a climate event that is causing some big changes.

536 may have been the worst year in history, but it wasn't the worst of all time: https://en.wikipedia.org/wiki/Population_bottleneck#Humans

Who knows how 2021 will be. We should also prepare for a 536 type event. With 8 billion people to feed I wonder the effect it would have nowadays.

Maybe the Younger Dryas would have been close to as bad...

Now I'm wondering (and worried) about the possibility of intentionally triggering volcanic eruptions to cool down a heating planet.

Not a good idea as the emanated Sulphur dioxide is a terrible greenhouse gas.

Indeed, but the smoke reduces heat penetration (otherwise the aforementioned ice ages wouldn't have occurred).
