"Mega El Niños" linked to Earth's largest mass extinction

A recent study reveals that a series of "mega El Niños" contributed to the largest mass extinction event, known as the Great Dying, around 252 million years ago. This event resulted in the extinction of approximately 90% of ocean species and 75% of terrestrial species. Volcanic eruptions in Siberia triggered extreme climate changes, leading to prolonged droughts and flooding, exacerbating the crisis.
