Mounting evidence suggests that dramatic increases in ocean temperatures—a rise of... The scientific consensus is that the main cause of extinction was the flood basalt volcanic eruptions that created the Siberian Traps, [19] which released sulfur dioxide and carbon dioxide, resulting in euxinia and anoxia, [20] [21] elevating global temperatures, [22] [23] [24] and acidifying the oceans.The end-Permian mass extinction (ca. 251.9 Ma) was Earth’s largest biotic crisis as measured by taxon last occurrences (13–15).Large outpourings from Siberian Trap volcanism are the likely trigger of calamitous climatic changes, including a runaway greenhouse effect and ocean acidification, which had profound consequences for life on land and in the oceans (16–18).First, we need to be clear on what we mean by ‘mass extinction’. Extinctions are a normal part of evolution: they occur naturally and periodically over time. 1 There’s a natural background rate to the timing and frequency of extinctions: 10% of species are lost every million years; 30% every 10 million years; and 65% every 100 million years. 2 It would be wrong to assume that species ...Permian extinction, also called Permian-Triassic extinction or end-Permian extinction, a series of extinction pulses that contributed to the greatest mass extinction in Earth’s history.
