Burning coal caused the largest mass extinction in earth’s history — the Late Permian Mass Extinction, or the Great Dying.
. To this day, bivalves are widespread, while only a few orders of brachiopods remain.
Many researchers have speculated that the End-Permian may have catalyzed diversification among tetrapods. Though the extinction wiped many out permanently, the Early Triassic saw the creatures diversify and expand their ranges rapidly.The same factors that have driven anthropogenic global warming today drove global ecological collapse at the end of the Permian. An over-abundance of greenhouse gasses made the planet unlivable for most living organisms.
“It was the same climate change caused by the same greenhouse gasses as what we’re seeing today,” Elkins-Tanton says. “And it was almost the end of multicellular life on earth.”we can keep global warming to levels far below the ones that scorched the earth during the“The rate of change might not have been as fast as today, but it changed the temperature so much that it’s really the worst-case scenario of what might happen,”. “That’s why we should study it.
The future scenario, most-analogous to the End-Permian, would see humans continue to burn fossil fuels until few surviving organisms remained. It’s a scenario that may not represent the end of life on earth, but a fundamental change that would take millions of years to rebound from.
