What was the Late Antique Little Ice Age?

The Late Antique Little Ice Age was an extended period of cooling in the Northern Hemisphere during the sixth and seventh centuries AD. Triggered by major volcanic eruptions that blocked solar radiation, this prolonged cold spell caused widespread crop failures, famine, and hardship. The climate shift coincided with major historical disruptions, including the Plague of Justinian and the migration of early Slavic peoples.

What we know

• The Late Antique Little Ice Age was a long-lasting Northern Hemispheric cooling period occurring in the sixth and seventh centuries. [2]
• The cooling period was initiated by three large volcanic eruptions in 535/536, 539/540, and 547. [2, 4]
• Volcanic sulfate aerosols reduced solar radiation reaching Earth's surface, causing severe drops in European summer temperatures. [4]
• The climatic downturn contributed to crop failures, famine, millions of deaths, and the decline of the Roman Empire while influencing the migration of early Slavs. [2, 4]

Still open

• The exact geographical origins of the volcanic eruptions that caused the volcanic winter of 536 remain uncertain, with multiple possible locations proposed across different continents.
