As volcanoes continue to erupt,

随着火山继续喷发

levels of carbon dioxide steadily built up in theatmosphere.

大气层中的二氧化碳含量稳定上升

until around 630 million years ago,

直至大约6亿3千万年前

the layer of carbon dioxide became so thick

二氧化碳层的厚度已经足够

that it trapped enough heat to release the planet from its endless winter.

它截留的热量足以让地球摆脱冰冻的掌控

At last, a thaw began.

终于，冰雪开始消融

Fierce storms pounded the planet.

猛烈的暴风雨肆虐整个行星

and Earth's cold and slushy climate began to warm.

地球的天气开始变暖

In just a few hundred years,

短短数百年时间里

temperatures would rise dramatically,

气温大幅上升

and Earth's would never be the same.

地球不将不再一样

Fortunately,over time our planet's climate stabilised

幸运的是，随着时间流逝 气候逐渐稳定

and Earth slowly returned to normal.

地球缓慢地恢复正常

Volcanoes had set the stage for a dynamic new era.

火山设好了一个新时代的舞台
