Lightning has started underground coal- and peat fires that burn for decadesif not longer.
I once drove a millenial chick uber-insane by telling her that if AGW even existed it was still a “natural” process...because if she believed we were just intelligent apes, we were a product of nature and therefore natural; as animals our impact on the environment was also therefore a “natural” force. She had a complete conniption over semantics and was mad I was enjoying myself so much.
“Man’s pollution is NOT natural!!”
“When a bear poops in the woods, is that natural?”
“Yes!!!”
“If a man poops in the woods, is that natural?”
“NO!!!”
“Are you trying to say then, that Man is an alien from space??”
I was informed I was a “hater” and a few other choice things ;)
