纪录片《地球劫难日》 第09期 火山冬天

（单词翻译）

Using the evidence from Laki, Courtillot now built a model of how the Siberian Traps might have destroyed the world.

利用拉基的证据，Courtillot建立了一个模型解释西伯利亚地盾如何摧毁整个世界。

First, there would have been eruptions² sending thousands of tons of dust and ashes into the sky.

首先火山喷发将数千吨的尘埃送上天空.

Slowly the sun would have been blocked out and temperatures would have fallen.

阳光渐渐被阻挡，气温不断下降。

First we'll enter a winter, a volcanic³ winter,

首先造成全球性的冬天：火山冬天，

the dust and the sulphur will cool the atmosphere after each eruption¹ for years or tens of years.

每次喷发产生的尘埃和硫磺都会使大气降温，它会持续几年甚至几十年。

It would have been like a nuclear winter lasting⁴ decades.

这类似于核冬天，延续数十年之久。

But that would have been just the beginning.

但这仅仅只是开始。

As the sky's cleared, vast quantities of gas given off by the burning lava⁵

随着天空逐渐晴朗，熔岩挥发出的大量气体，

would have slowly wrapped the earth in a blanket of carbon dioxide, an extremely powerful greenhouse gas.

慢慢包围了整个地球，形成一个二氧化碳罩，二氧化碳是相当强大的温室气体。

Gradually, over thousands of years there would have been massive global warming.

渐渐地，几千年后地球上又出现了全球大变暖的现象。

The carbon dioxide will lead to a greenhouse effect and the cold will be replaced by unusual hot time.

二氧化碳会造成温室效应，严寒再次被高温所取代。

So you get the double hit, you're cold for a while and then hot for a longer time.

所以地球遭受了双重打击，先是一阵严寒，然后再是长期的炎热。

So that altogether after a million years, the earth would be different.

这些因素共同作用的100万年后，地球肯定已是面目全非。

The climate would be different and a mass extinction⁶ would have happened.

气候剧变，这势必会造成生物大灭绝。
