Way cool. Is this weather or climate change?
A restless planet for sure.

Stunning!
Global map of lightning frequency--strikes/km2/yr. The high lightning areas are on land located in the tropics.
On Earth, the lightning frequency is approximately 40–50 times a second or nearly 1.4 billion flashes per year and the average duration is 0.2 seconds made up from a number of much shorter flashes (strokes) of around 30 microseconds.
