Climatic change may have triggered the mass extinction at the end of the Permian period
Step-by-step explanation:
This climatic change is believed to have been brought up by a massive volcanic eruption that spewed millions of tonnes of carbon dioxide, hydrogen sulfide, and pyroclast into the atmosphere. The resulting abrupt climatic change, as a result, caused the extinction of approximately 96% of the species that existed at the time. It is identified as the largest extinction event in the earth’s history.
