A new study published in Nature Communications reveals that the Permian mass extinction, known as the "Great Dying," was exacerbated by the collapse of tropical rainforests. This loss significantly reduced the planet's carbon storage capacity, leading to prolonged extreme heat. Researchers analyzed fossil data from China, reconstructing vegetation maps before, during, and after the extinction. The findings highlight a climate tipping point: irreversible damage from rainforest loss, even if carbon emissions cease. This poses a dire warning for the future, as current global warming threatens similar rainforest collapse.
