And they didn't even need to make up Global Warming!
Gomorrah was a city on Soviet Earth many years ago in Demon Lord Dante. It was a high tech sci fi city with the city of Sodom and people lived in peace. But then an alien of energy who has no physical forme called God came over. So he goes to Earth and orders the people of Sodom to bow to him and let him have their bodies. They don't consent so He pulls a Weinstein and punishes them by killing/reviving them with His psychic powers. The Sodomites hatred for God let them absorb the psychic powers and evolve into what we now call Demons. He then used his energy to make the atmosphere of Gomorrah rain endlessly to flush em out in a flood. The survivors of this became modern dat Satanists. Then He split into billions of streams of ectoplasm and infected apes who evolved into modern day humans who forgot their connection to him.
