That's a new one. I hadn't heard that one before. I'll have to add it to
my list of other ones.

If the Earth has an excess of electrons and some of them move away to some
distance, what is it that causes a voltage difference to appear?

Electrons migrate very high. Storm clouds are to 18 km high. But electron
migrate higher. In sunny day the electrons are emitted intensely by thermo-
and photo- emission. In such time H2O aggregates contain more electrons
(than in night) and migrate higher.
We do not know how high is absolute Earth voltage but in clear air is lower.

FYI, I've been in a location with a clear sky that had more "charge" than
other areas. After noticing my 2m ham antenna on the car was giving me
1/4 inch arcs to the frame of the car, I decided it was best to leave the
area. The sky was clear. By the time I was 4 miles away, the spot I was
at had big cloud starting to billow up from it.

In sticky air is plenty of electrons but the voltage is relatively low. So
you have only 1/4 inch SPARKS (In sparks electrons oscillate - in arc no).
After condensation the voltage rises.

So why that one spot and not another spot in the same clear sky?

Thats are details.

Your topic is about the Faraday paradox. At analysing such phenomenon you
must take into account that on all elements and in the air is an excess of
electrons.
