A team of scientists has identified an additional force that likely contributed to a mass extinction event 250 million years ago. Its analysis of minerals in southern China indicate that volcano eruptions produced a “volcanic winter” that drastically lowered earth’s temperatures--a change that added to the environmental effects resulting from other phenomena at the time.
The research, which appears in the journal Science Advances, examined the end-Permian mass extinction (EPME), which was the most severe extinction event in the past 500 million years, wiping out 80 to 90 percent of species on land and in the sea.
“As we look closer at the geologic record at the time of the great extinction, we are finding that the end-Permian global environmental disaster may have had multiple causes among marine and non-marine species,” says Michael Rampino, a professor in New York University’s Department of Biology and one of the authors of the paper.
