    Post The worst year ever to be alive was caused by two volcanos in 536 A.D.

    I wasn't even aware this was a historical mystery until now.

    Why 536 was ‘the worst year to be alive’
    By Ann Gibbons, Nov. 15, 2018 , 2:00 PM

    Ask medieval historian Michael McCormick what year was the worst to be alive, and he's got an answer: "536." Not 1349, when the Black Death wiped out half of Europe. Not 1918, when the flu killed 50 million to 100 million people, mostly young adults. But 536. In Europe, "It was the beginning of one of the worst periods to be alive, if not the worst year," says McCormick, a historian and archaeologist who chairs the Harvard University Initiative for the Science of the Human Past.

    A mysterious fog plunged Europe, the Middle East, and parts of Asia into darkness, day and night—for 18 months. "For the sun gave forth its light without brightness, like the moon, during the whole year," wrote Byzantine historian Procopius. Temperatures in the summer of 536 fell 1.5°C to 2.5°C, initiating the coldest decade in the past 2300 years. Snow fell that summer in China; crops failed; people starved. The Irish chronicles record "a failure of bread from the years 536–539." Then, in 541, bubonic plague struck the Roman port of Pelusium, in Egypt. What came to be called the Plague of Justinian spread rapidly, wiping out one-third to one-half of the population of the eastern Roman Empire and hastening its collapse, McCormick says.
    There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.

    It seems the historical mystery was not that a volcanic eruption(s) caused the unusually cold climate in those years but precisely which volcano. Tree ring and ice core data from Greenland and Antarctica had already pointed to volcanoes as the cause. The article discusses new ice core evidence that shows volcanic fragments matching that which would be produced from Iceland.

    Ice cores really are a fabulous record of the past. Good article.
