Atolls, in an undeveloped state, will always be just a few feet about sea level. They are the result of an equilibrium between deposition and erosion. If the sea level were to drop, an undeveloped atoll (without walls, paving, etc) would erode downwards because of greater wind exposure. Attempting to fix the level of an atoll by paving it will not work in the long term, regardless of what the climate does.
- Retric 11y agoThat's more or less the definition of an Atoll, but nothing says something that used to be an Atoll needs to stay above water.
- 23452436 11y agoWhat's the function of "but" there?
- Retric 11y agoA less formal version of However used to denote contrast. In this case the difference between current state, and future state.
- 23452436 11y agoThere was nothing contrasting in the original reply. Just sayin'.
- Retric 11y agoTry rereading it, and note the words: "an Atoll" vs. "used to be an Atoll"
- ertyuiopas 11y agoIn your original reply, your first sentence was false. Your second sentence was an unrelated truism. No contrast, no point in in adding the connecting "but".
- Retric 11y agoReading your other posts demonstrates you are clueless about this and other topics. I would suggest a lot more research using textbooks to get a basic understanding going of chemistry, english, physics, and geology.
- 23452436 11y agoFind one error besides typos to back up your bloviating.
- Retric 11y ago"CO2 isn't even the main greenhouse gas, that's water vapor." That's ridiculously false. Nitrogen is the main greenhouse gas. It's also stable and thus not an issue for climate change, but trying to correct someone whose basic understanding is false is not worth the effort.
- 23452436 11y agoReply to the above: Oh, you've built a climate model? Is it one of the ones that doesn't work? That'd be all of them. You're wrong about your correction and abuse won't substitute well. Now find an error or quitcher bloviating, bolviator.
- Retric 11y agoAnd you still can't find the reply button? Also, note climate models are one thing weather models are another and weather models clearly do work. PS: Thermodynamics really takes differential equations, and I suggest you read up on both of them.
- dredmorbius 11y agoIf your primary form of deposition (coral formation) breaks down, a lot of former atols will be sub-optimal investments, in the "under-water" sense that means being under water.
- ertyuiopas 11y agoThe main deposit is sand, as I understand it. That's why atolls change shape a lot. On the whole, they're not even as stable as coral. Building (with paving) is just a bad idea.
- dredmorbius 11y agoMy understanding is seamount (underwater volcano) on which coral builds further toward the surface, from depths of < 200' (~60m), topped with sand which is almost certainly formed from coral. The sand topping will blow way in wind, but with slow sea rise, coral can build up. Coral cannot grow above sea level, so atolls are of necessity close to sea level. With rapid rise, particularly where coral growth is retarded (carbonate levels, other forms of coral blight), you'll lose that ability entirely, and the island will flood.

- 23452436 11y agoCorrect. Atolls (the bit above water) are mainly sand, regardless of the sand's origin. Not a good place to build.
