So much for carbon dioxide being a “harmless” gas.The worst mass extinction in Earth’s history may have been caused by huge amounts of carbon dioxide that accumulated in the atmosphere and the ocean after colossal volcanic eruptions in Siberia 252 million years ago, according to a new study.

In addition to coating ancient Siberia with thick lava, the famed eruptions also released massive amounts of carbon dioxide into the atmosphere, which the study says may have turned the oceans sharply acidic. That acidity is thought to have driven a “global environmental calamity” that killed 90 percent of Earth’s species — also known as the “Great Dying” between the Permian and Triassic periods.
