In 1986, an enigmatic cloud surfaced from an African lake. Due to its greater density than air, the cloud descended upon a neighboring village. Tragically, the inhabitants, both human and animal, fell unconscious, resulting in the loss of thousands of lives. The key question is: What unfolded? Within this puzzling cloud lay 300,000 tons of carbon dioxide. Astonishingly, geologists continue to grapple with the mystery of its trigger, as its release remains a puzzle to this day.
