Does anyone happen to know how, or even if, changes in sea level affect the Earth's atmosphere? I haven't been able to find anything about that online. I know that air pressure is the result of the downward force of the atmosphere on the Earth, but no where does it say it is affected by changes in sea level.
I feel very smug in suggesting that any change in barometric pressure would be significantly less than driving from New Orleans to Denver. The only mechanism would be to raise the atmosphere by 66 meters over most of the planet which would cause a minor decrease in the gravitational force on the atmosphere.

Re: Creationists
Sorry admins, I made another double post. I might as well make the most of it by pointing out that there isn't really a 'whirlpool' in the North Atlantic, just a gentle sinking of surface water. Every winter the NA surface waters cool and reach their point of maximum density, at which point they sink and form a current. Same mechanism as seasonal 'turnovers' in temperate lakes, but much larger scale.
Freshwater however is less dense and there is concern that increased freshwater input out of melting Greenland icecaps could put a low-density layer near the surface which would shut down the current, doing nasty things to Europe (glaciation) and perhaps other parts of the globe. I've heard professors claim that adherents to this notion believe such effects could begin on timescales of as little as a decade. The water itself takes thousands of years to make one circuit *but* a cutoff of energy would be felt almost instantly, just as individual electrons in a current flow about as fast as molasses but current changes travel down the wire at nearly the speed of light.

Re: an introductory article on the grand canyon from the creationist side
Hey Jazzlover,
Rather than cutting and pasting from YEC sites why don't you try using your own arguments? For example you could piece together your scenario of Grand Canyon formation and use the article as a reference. That way I could debate *you* instead of Austin, who is not present here to argue with us.

So I guess I'm asking the same question. What about it? Would raising the ocean levels up to just over 29,000 feet have a major impact on the atmoshpere?
Why would it? If I dug 29,000 feet of crust off the planet and sent it somewhere else, so that every point on Earth is now 29,000 ft lower, what difference would it be to the atmosphere? It would simply move in closer, and be under slightly more pressure because it is now 29,000 ft closer to the Earth's center of gravity. Further, if I pushed the bottom of the atmosphere up 29,000 feet the effect would be the same, and still minimal.
Suppose I have a glass tube that's 30,000 ft tall. The base of the tube is at sea level. The pressure stratification of the atmosphere inside is identical to the stratification outside. I seal both ends and carry it up to the summit of Everest. The same amount of air is still in the tube, and it is still stratified. The air at the base of the sealed tube is nearly at the same pressure it was at when the tube was at sea level. The slight difference is because the air is now further away from Earth's center, and, to put the difference in perspective, is directly proportional to the difference of my own weight at this altitude.
We instinctively believe that there must be "some" significant difference because of our personal experiences that the air at altitude is "different". But that misleads us under these conditions.

A count, by side of the debate, would still be interesting though.
I sill feel bad for "accidentally" stating that ice is denser than liquid water...and being caught.
