Carbon in Earth

Once you are in this geostationary orbit right over the tower, just lower your carbon nanotube cable down from the satellite, tether it to the tower here on Earth.

一旦你来到这个塔旁的地球静止轨道，只需把碳纳米管电缆从卫星上放低然后将其系在位于地球的塔端。

Volcanic carbon dioxide in Earth's early atmosphere kept Earth warm enough for life to begin during the time when the Sun was too dim to provide much warmth.

地球早期大气中的火山二氧化碳使地球足够温暖，保证生命在太阳过于昏暗而无法提供足够热量的时候能够得以孕育。

The molecules of carbon dioxide in the Earth's atmosphere affect the heat balance of the Earth by acting as a one-way screen.

地球大气层中的二氧化碳分子像一个单向屏一样影响着地球的热量平衡。
