About 252 million years ago, Siberian volcanoes heated Earth's oceans until much of marine life effectively suffocated — and scientists have now confirmed the same deadly combination of warming and oxygen loss is developing again today. - Space Daily

A 2026 PNAS study links end-Permian extinction patterns to temperature-dependent hypoxia, while modern observations show oceans are warming and losing oxygen. The mechanisms align, but the ancient catastrophe is not a direct forecast of present conditions.

About 252 million years ago, a cascade of environmental changes pushed life in the oceans beyond its physiological limits. Massive volcanism in what is now Siberia loaded the atmosphere with greenhou… [+8453 chars]
