God had created the expanse of water in the heavens that shielded the earth from the sun. This is what He considered to be the the right way to build the earth. Then comes flood, and now you can see the sky and the water vapor canopy is gone. So would it be expected that after Armageddon, God would put it back to the way it was, the "right" way, or is mankind expected to live forever on an earth that was altered from its original, perfect design because of the badness of every living thing?
A more fundamental problem with the heavenly water expanse involves these factors:
- A vapor canopy with more than twelve inches of precipitable water would raise the temperature of the earth above boiling (Morton 1979). A vapor canopy of only four inches of water would raise the temperature of the earth to 144 degrees F. It is worth noting that several prominent creationists agree with this conclusion, yet their close colleagues continue to teach that there was a vapor canopy (Morton 2000).
- A vapor canopy capable of producing the global flood would have increased earth's atmospheric pressure from 15 PSI to 970 PSI.
- Some creationists try to solve the vapor canopy problems by moving the canopy out of the earth's atmosphere and into orbit. A canopy of orbiting ice would have been unstable (it could only exist in a ring much like Saturn's). It would have cooled the climate (probably just slightly) until it somehow collapsed to cause the flood. Then the release of its gravitational potential energy would have converted all the ice into superheated steam, not into a flood. - http://www.talkorigins.org/indexcc/CH/CH310.html
