GLOBAL ELECTRIC CIRCUIT. “The voltage difference between ground and ionosphere is 200,000 to 500,000 volts (200 to 500 kV). Even in fair weather, a slight current of 2 pA (picoamps, or 0.0000000000001 A) flows from every square meter of ground upward to the ionosphere. Thunderstorms alone send 1 A of current skyward. Indeed, the flash rate for a storm is directly related to its current flow. While this view is widely accepted, it has not been proven by hard data.”
