Scientists have unlocked the mystery behind Earth’s deadliest mass extinction: it wasn’t just about climate change—it was about metabolism. Creatures with faster metabolisms, like today’s fish and snails, survived the ocean’s deadly heat and low oxygen, while sluggish brachiopods perished. Triggered by volcanic CO2, the event mirrors our current climate crisis, warning that rising temperatures could overwhelm even ancient survivors. New experiments show how oxygen demands spiked under heat, revealing why today’s oceans may face similar fate if we don’t act. Listen in comfort:Get a discount on…
