"Geology experts find evidence of dual mass extinctions 260 million years ago

(...) In a study published in the journal Earth and Planetary Science Letters, researchers say their analysis provides evidence that the oxygen-deprived oceans precipitated two mass extinctions around 259 million and 262 million years ago during the Middle Permian Period.

By studying these ancient extinctions, researchers can better predict how modern-day global warming could affect the ocean's food chain.

"We are studying the biocrisis in the Permian Period, but similar warming is happening today because of human events," said Thomas Algeo, a study co-author and University of Cincinnati professor of geosciences. "Humans are mimicking the effects of volcanic eruptions as a consequence of the release of carbon into the atmosphere."
