Re: Ararat & the Black Sea

If you're not trying to prove the biblical flood then what are you trying to prove? If you're saying that the biblical account of the flood is an exaggeration then why bother trying to prove that all life could be wiped out by a flood. If your account of the flood is plausible then it's equally as plausible to say that Noah was a bronze age guy who built himself a raft to survive a local flood (say the Black Sea flood) and his story has been exaggerated since.

Why wouldn't the heat be given up to space?

Radiation is by far the least efficient form of heat transfer, heat would radiate out into space but at such a slow rate that the heat left in the atmosphere would cook anyone on earth.

Is the amount of heat generated linear in fashion in comparison to the tempurature?
In other words, the hotter it gets, the harder it is to get hotter?

I'm not sure what you're trying to say here.

Another thought, if the process that was causing the evaporation was thrusting the water higher up in the atmosphere than usual, it would be subjected to lower atmospheric pressure, which would reduce the boiling point, and it may actually boil off, and lose a lot of its energy, and heat. What do you think?

Meteorology is not my bag so I have no answer to this. But even if the water "lost" its heat/energy, where would it go? Energy can be neither created nor destroyed, it only changes forms. If the water "lost" the energy something would have to gain it. The energy/heat would be transferred to something else and you'd be back to cooking the planet.

If it lost its heat, it would lose it to space. Space is mighty cold.

So you're saying that all the water vapour will rise up to the very very edge of the atmosphere, lose its heat to space and then come back down as rain?. That's ludicrous. Water vapour condenses into liquid water when its temperature drops to a certain point, if the water vapour doesn't cool down until it hits the end of the atmosphere that means the atmosphere has to be incredibly hot down at ground level.

Not only that it would be colder than the atmosphere as it fell back down, and would have a cooling effect

As rain falls it gains kinetic energy from motion and thermal energy from air friction. Rain gets hotter as it falls.

Going back to my first paragraph, the rain coming down from the edge of space would gather an insane amount of kinetic energy that would be released when it hit the ground, again increasing the temperature on the ground. Once again you're having a giant barbecue with Noah and the animals.

edited to add: I reccomend going down to your nearest library and picking up introductory texts in meteorology and heat transfer. Study them in your free time.
