It says that variations in earth's movements, specifically in its orbit around the sun, these variations lead to differences in the amount of solar energy that reaches the earth.

这一假设认为，地球运行的变化，特别是绕太阳轨道的变化，会导致太阳到达地球能量的不同。

They were started by slow and subtle shifts in the orbit of the Earth that changed the amount and distribution of radiation reaching us from the sun.

地球轨道缓慢而微弱的变化改变了阳光照射我们的数量和辐射的分布，从而引发了这些变化。

That is, the amount of debris... Currently in orbit has reached a threshold where it will continually collide with itself, further increasing the population of orbital debris.

这就是说，现在在轨道上的残骸的数量已经到达了一个数值，然后它们就会慢慢开始自己相互碰撞，这样就会产生新的碎片。

They warn that the amount of junk in Earth's orbit is increasing and, as it does,the risks to satellites and space vehicles,also rise.
