E_2_02 — Toba Supervolcano and the 74,000 BP Genetic Bottleneck

Approximately 74,000 years ago, the Toba supervolcano on the island of Sumatra (modern Indonesia) produced the largest volcanic eruption in the last 2 million years: a VEI-8 (Volcanic Explosivity Index maximum) event tha

E_3_19 — Volcanic Aerosol Forcing and Historical Climate Disruption

Explosive volcanic eruptions inject sulfur dioxide (SO₂) into the stratosphere, where it converts to sulfate aerosol particles (H₂SO₄) that reflect incoming solar radiation and cool Earth's surface for 1–3 years. This pr
