TED-ED: The colossal consequences of supervolcanoes - Alex Gendler

The video discusses the 1816 'Year Without a Summer,' caused by the 1815 eruption of Mount Tambora, a supervolcano. This eruption led to global climate anomalies, crop failures, and societal unrest. Historical eruptions like Huaynaputina and others have also had significant impacts, including famines and civilization collapses. The video explains the dangers of explosive calderas, such as the one under Yellowstone, and the challenges in predicting and mitigating supervolcano eruptions. Despite current monitoring efforts, the potential for a civilization-ending eruption remains a concern.
