Climate
The Earth's climate is changing because the orbit around the sun is not always the same.
Explanation
All the planets influence the movement of the Earth. As a result, the position of the earth's axis is not always at the same angle. Moreover, the axis wobbles a little. Sometimes the orbit is elliptical and the distance from the earth to the sun varies. This leads to climate fluctuations with cycles ranging from 21,000 to 2.4 million years.
The planets move so chaotically that their orbits are unpredictable.
