纪录片《地球劫难日》 第11期 理论缺陷

The geological record shows that when world temperatures rise abruptly¹ by 4/5 ℃, many species will die,

地质记录显示，当全球温度突然上升4-5℃时，很多物种都会灭绝，

but he could also see there was no evidence that such an increase would wipe out 95% of all life.

不过没有任何证据显示这类升温现象会导致95%的生物消亡。

His calculation showed that to do that would require a much bigger increase in temperature, perhaps double.

他的计算结果表明，要造成这种灾难，温度必须升得更高，或许是两倍。

Well, scientist estimate that a rapid temperature rise of maybe 10 ℃

科学家们算出只有当气温突然升高10℃时，

is going to be necessary to kill off so many animals and plants and everything else.

才有可能杀死这么多动物和植物以及其它生物。

5 ℃, the Siberian Traps with their 5℃, it would have created certainly climate change,

西伯利亚地盾造成全球升温5℃，这确实会引起气候剧变，

but a massive extinction²? I don't think so.

但至于引起生物大灭绝我觉得不太可能。

It seemed there was a flaw in Courtillot's theory.

看来Courtillot的理论确有缺陷。

The Siberian eruption³ would have been deadly, but not that deadly.

西伯利亚火山爆发的确很可怕，但还不至于如此具有毁灭性。

Something even more catastrophic must have been at work.

一定还有更恐怖的灾难。
