No volcanic winter in East Africa from ancient Toba eruption: The supereruption 74,000 years ago did not trigger major environmental disruption that caused human populations in East Africa to decline, say geoscientists.

via Science Daily, 06 Feb 2018: The Toba supereruption on the island of Sumatra about 74,000 years ago did not cause a six-year-long ‘volcanic winter’ in East Africa and thereby cause the human population in the region to plummet, according to new research based on an analysis of ancient plant remains from lake cores. The new findings disagree with the Toba catastrophe hypothesis, which says the eruption and its aftermath caused drastic, multi-year cooling and severe ecological disruption in East Africa.
