Calling Scully and Mulder... :-)
There is a verse in the Bible that says He rolled back the Heavens like a scroll. I would welcome it if that is what it is. I do not believe in man-made global warming for one the idiots that say it is a fact say for a fact we had an ice age after a tropical earth. So what is it naturally without man? Tropical Dinos drove SUV and had too many factories. Tropical plant life has been found in the antarctic.
