A little while ago you were arguing, with Photizo, that the similarity of all the Flood stories argued for a common inspirational event. At that time the non-fundies (the religious theist, the areligious theist, the religious atheist, and the areligious atheist, all together) pointed out to you that Flood stories worldwide have little in common besides a Flood and ensuing hardship.
In modern climate change mythologies, all the weather events we see world wide, are being attributed to manmade impact. The two myths of the great flood and the man made climate change, have the same thing in common, in that man upsets the natural balance, requiring the god/earth to create exaggerated events that are deadly until balance is restored.
In modern times, we one might attribute this change to natural events all places on earth. But then, as now, man is held responsible for this impending global scale catastrophe, because man went unnatural with respect the earth and aroused the wrath of the gods/earth.
The only real difference between these two mythologies is who is the bad guy. The great flood stories choose the righteous by God as the innocent. Now, it is the atheists and liberals who are innocent in their mythology, because they have repented of carbon emissions. The evil bible toter religion who are conservative=republican=business are the evil ones that will be purged by man if they don't repent. There is a competition for religious devotion.
This mythology will not last for thousands of years unless the predictions come true. Then it will be a teaching moment.
