1816 was The Year Without A Summer. At the time people in Europe didn't know why it didn't heat up that summer, but it was a catastrophe for humans who lived in the northern hemisphere, in every sense of the word.
Catastrophe: an event causing great and often sudden damage or suffering; a disaster. "a national economic catastrophe"
> The year 1816 is known as the Year Without a Summer because of severe climate abnormalities that caused average global temperatures to decrease by 0.4–0.7 °C (0.7–1 °F).[1] Summer temperatures in Europe were the coldest on record between the years of 1766–2000.[2] This resulted in major food shortages across the Northern Hemisphere.[3] > > Evidence suggests that the anomaly was predominantly a volcanic winter event caused by the massive 1815 eruption of Mount Tambora in April in the Dutch East Indies (known today as Indonesia). This eruption was the largest in at least 1,300 years (after the hypothesized eruption causing the extreme weather events of 535–536), and perhaps exacerbated by the 1814 eruption of Mayon in the Philippines.

1816 Summer in France was 3 degrees celcius cooler than average: https://en.wikipedia.org/wiki/Year_Without_a_Summer#/media/F...
How do you prepare for both a certain "volcanic winter"-type events (losing growing seasons in the northern latitudes) and the possibility of anthropogenic climate change?
How many people would die if we had two volcanoes go off, in 2022 and 2023, like what happened in 1814 and 1815?

My understanding is the 1814 and 1815 volcanic eruptions reduced the amount of heat absorbed by the oceans [0]. By 1816 the oceans were super-chilly, and didn't have enough heat to give off for Europe to have a normal summer.

Climate is variable. Deal with it. Volcanoes are much more of a threat to humans than slow moving disasters.
