I hope you understand the difference between isolated ions
existing in the air and the air being ionized into a
conducting path. Isolated ions is not corona.

Nevertheless, air is in a constant state of conduction. It may
only be picoamps per square meter but it still exists and it's
what causes the earth to be a lousy capacitor.
