1: There are most certainly accurate measurements of orbital distance, probably accurate to a few miles or less (to gravitational centers, not surfaces), and probably calculated back millions of years. I wasn't inspired to try and look them up.

2: The temperature changes caused by the microscopic variations in this measurement over millions of years are lost completely in the noise. The tiniest belch in the solar output, or almost any other astronomical factor connected to climate, would wash it out completely.

In any case, the variation in orbital distance over time is extremely constant, never changes drastically, and is spread over hundreds of millions of years.

There is no connection between the mean distance of the Earth and the sun, and abnormal climate changes.

I swear on everything I hold sacred that this is true.

Please, please, don't go there. Your theory is baseless.
