The geological record shows that when world temperatures rise abruptly by 4/5 ℃, many species will die,
地質(zhì)記錄顯示，當(dāng)全球溫度突然上升4-5℃時(shí)，很多物種都會(huì)滅絕，
but he could also see there was no evidence that such an increase would wipe out 95% of all life.
不過沒有任何證據(jù)顯示這類升溫現(xiàn)象會(huì)導(dǎo)致95%的生物消亡。
His calculation showed that to do that would require a much bigger increase in temperature, perhaps double.
他的計(jì)算結(jié)果表明，要造成這種災(zāi)難，溫度必須升得更高，或許是兩倍。
Well, scientist estimate that a rapid temperature rise of maybe 10 ℃
科學(xué)家們算出只有當(dāng)氣溫突然升高10℃時(shí)，
is going to be necessary to kill off so many animals and plants and everything else.
才有可能殺死這么多動(dòng)物和植物以及其它生物。
5 ℃, the Siberian Traps with their 5℃, it would have created certainly climate change,
西伯利亞地盾造成全球升溫5℃，這確實(shí)會(huì)引起氣候劇變，
but a massive extinction? I don't think so.
但至于引起生物大滅絕我覺得不太可能。
It seemed there was a flaw in Courtillot's theory.
看來Courtillot的理論確有缺陷。
The Siberian eruption would have been deadly, but not that deadly.
西伯利亞火山爆發(fā)的確很可怕，但還不至于如此具有毀滅性。
Something even more catastrophic must have been at work.
一定還有更恐怖的災(zāi)難。
