Eruption of Alaska's Okmok volcano linked to period of extreme cold in ancient Rome

Scientists and historians have found evidence connecting an unexplained period of extreme cold in ancient Rome with an unlikely source: a massive eruption of Alaska's Okmok volcano, located on the opposite side of the Earth. A new study uses an analysis of tephra (volcanic ash) found in Arctic ice cores to link this period of extreme climate in the Mediterranean with the caldera-forming eruption of Alaska's Okmok volcano in 43 BCE.
