It’s all them damn penguins dancing that’s doin it!...........
You might be on to something.
The penguin dances COULD be starting vibrations at frequencies and amplitudes sufficient to MOVE the heavier than air CFCs ALONG the ice and UP the mountain slopes where they are LAUNCHED into the air by the “Mountain Waves” with enough velocity to reach the stratosphere.
Yeah! THAT’S what’s happening.
...little did we know that it was the penguins all along...
