-The dual blow of a little ice age and yet another pandemic. In the 530s and 540s, volcanic eruptions rocked the globe. We have long known that in the year 536 there was no summer; for about 15 months, the sun seemed to shine only dimly, unnerving people worldwide. -
-First, in AD 536, there was a massive eruption in the Northern Hemisphere. Second, in AD 539/40, a tropical volcano erupted. The result was not just a year of darkness but truly staggering global cooling: The decade 536 to 545 was the coldest decade of the last 2000 years,
-with average summer temperatures in Europe falling by up to 2.5 degrees Celsius. And this was no passing phenomenon. For a century and a half, colder temperatures prevailed across large parts of the Northern Hemisphere. Just as the climate started to turn colder,-
-the plague appeared on the Southern shores of the Mediterranean — in AD 541. This was true bubonic plague, caused by the bacterium Yersinia pestis, the agent of the more famous medieval Black Death. The plague is at root a disease of rodents, -
-and had been endemic among social burrowing rodents in central Asia. It probably traveled to Rome across the trading networks that carried silks from China to the Mediterranean. The plague first spread from one rodent species to another, carried by fleas -
-ultimately infecting black rats, which live in close quarters with humans. Once the bacterium reached the rats of the Roman Empire, it was mayhem.
