What If Every Volcano on Earth Erupted at Once

January 15, 2022: one underwater volcano in Tonga threw a plume about 58 kilometers high. The USGS counts about 1,350 potentially active volcanoes on land. This is the thought experiment. All of them. Same hour. A science what-if, not a forecast. Counts and climate figures are public-record ranges. When a number is an estimate, we say about. 0:00 One volcano, then 1,350 0:38 T Equals Zero 1:54 The First Hour 3:03 Who Lives Close 4:02 The Sky Closes 5:12 And It Gets Worse 6:44 The Laki Fog 7:43 The Ocean Floor 8:40 What Does Not Happen 9:46 After The Ash Thought experiment only. Not a prediction that this can happen. Magma chambers do not share a switch. #volcano #whatif #scienceexplainer #eruption #climate #Tambora #Pinatubo #earthscience Tags: volcano, what if, science, eruption, Tambora, climate, Ring of Fire, earth science Visuals are original AI-generated stills.
