New high-resolution lake records from Lake Chala near Kilimanjaro show Mount Toba's 74,000-year eruption cooled eastern Africa by about 0.5°C for roughly 18 months, a far milder regional impact than once imagined and not clearly indicating a global threat; researchers caution that conclusions come from a single site and more records are needed to assess worldwide effects.
New archaeological and tephra evidence from Africa shows that the 74,000-year-old Toba eruption, though vastly larger than Mt. St. Helens, did not trigger a uniform human extinction; sites in South Africa and Ethiopia reveal continuous habitation and adaptive behaviors—microlithic tool trends, early bow-and-arrow tech, and sophisticated foraging—dated to the eruption period. These findings revise, but do not fully dismiss, the Toba catastrophe hypothesis and highlight refugia and migration pathways out of Africa via arid periods and dry‑season river corridors known as blue highways.
Microscopic glass shards from the Toba supervolcano eruption in Ethiopia suggest that early modern humans survived the event by adapting to extreme arid conditions, shifting their diet to include more fish. This challenges the idea that humans couldn't survive in such climates and offers an alternate theory for human dispersal out of Africa. The study also provides evidence that humans were flexible in their adaptations and could overcome environmental challenges, contradicting the popular belief that the Toba eruption nearly drove humans to extinction.
