研究揭示了2.94亿年前的火山爆发 导致了二氧化碳的激增 引发了古代全球变暖 Study reveals volcanic eruptions 294 million years ago caused CO2 spike, triggering ancient global warming.

来自圣安德鲁斯大学的科学家分析了化石大鼠贝壳,以研究在335至2.65亿年前的后白骨冰时代的二氧化碳水平。 Scientists from the University of St Andrews analyzed fossil brachiopod shells to study CO2 levels during the Late Palaeozoic Ice Age, 335 to 265 million years ago. 他们发现,由于火山爆发,导致全球变暖和冰融化,二氧化碳水平一直很低,直到大约2.94亿年前突然上升。 They found that CO2 levels remained low until a sudden rise around 294 million years ago due to volcanic eruptions, leading to global warming and ice melting. 该研究报告在《自然地球科学》中发表,强调二氧化碳在气候调节中的关键作用,并警告无节制排放今后的潜在影响。 The study, published in Nature Geoscience, highlights CO2's crucial role in climate regulation and warns of potential future impacts from unchecked emissions.
