Yes, genius, a ball can only have fallen if it was once in a higher position.

There is a physical mechanism for these changes.
In the case of the ball, it falls because of the gravitational pull at the Earth's surface. In the case of the global temperature,
it is warming from the increased greenhouse effect due to human activities.
All you have is correlation of what you think are causes with what you think are their effects. The Earth has been much warmer than it is now. Not only did life survive but it also demonstrates that there are cycles in play that over-ride mere human pollution.
The Volstock ice cores show this record of climate cycles long before a modern human being ever lit a fire.

In order to show 'climate change' is continuing, AGW zealots have to fiddle with the temperature data, as they were caught doing here:
