I can't believe that global warming will kill off the reefs.

I just took a statistics class related to corporate operations. It was interesting to hear that 70-80% of "hunches" are wrong. Sure people/corps get by but many times over they don't attack the "correct" problem - just the symptoms. (this is probably why a lot of insurance companies are starting to support chinese/alternative medecines like herbs/accupuncture. Current drugs are $$ and many times they treat symptoms or cause other problems)

I'm not sure if there is a good way to chemically deal with chronically low pH without throwing other parameters out of whack. It's not something anyone in the hobby will have to worry about within our lifetimes though. In the wild, a fall-behind state starts at a much higher pH than in captivity since we eliminate most of the bioeroders, competitors, and disturbances corals contend with. In the wild a pH of 7.8 would be the end of active reef growth, but in captivity we can still get positive (if slow) net growth. Our corals don't have to deal with parrotfish, rock boring sponges/clams/urchins/algae, hurricanes, uncontrolled macroalgae, etc. like they do in the wild. As a result, as long as calcification is still even slightly energetically favorable you can still get positive net growth and no ecological succession in captivity.

What is this hole I'm digging? Just because I don't agree with a theory that other people agree with I'm looking silly? Have ANY of my responses to this thread been serious? After reading interweb discussions for the past 12 years I've came to same conclusion, nobody changes their opinion over the interweb.
Life is a terminal disease, lighten up dude and don't be a sheep.

Calcification is just another chemical reaction. Changing the pH changes how energetically favorable it is. At higher pH, around 8.2, it's very favorable and proceeds easily. As the pH gets lower, it becomes less and less favorable until eventually it reaches equilibrium and then reverses (like in a calcium reactor). As it becomes less favorable, it also becomes more costly to the animal to calcify. So, yes growth rate is affected by pH. That's why the corals would be falling behind. Their growth would slow while bioerosion and disturbance stay the same.

I don't really think the gov. would be able to confiscate if we've already obtained the corals well before the reefs were destroyed....And as far as global warming goes, I really don't feel it's an issue. Yes, temps and water levels are higher but from other studies "scientists" have found that this is just a natural cycling of the earth. We've went through times like this before based on sediment studies in the ocean and so forth...ENOUGH OF THIS SCIENTIFIC GARBAGE, The reefs will be fine as long as us "reefers" do our deeds and aquaculture all our corals and stop taking corals from the wild when plenty are available in the aquarium "market"...

Please clear up this scientific garbage and educate us about this evidence that any natural cycles alone can explain the current degrees of warming. When was the last time the predicted changes occurred and what were reefs like then?

The last time there was a global warming event was 55 million years ago during the Paleocene-Eocene thermal maximum. The event was primarily fueled by the release of frozen methane deposits and increased the global temperature around 5C. It upset oceanic and atmospheric circulation, lead the extinction of many deep sea and sandbed (benthic zone) creatures and reshaped species and life on land leading to the emergence of the mammals we see today.
The last time a global warming event occured as a result of greenhouse gasses was 180 million years ago during the jurassic period. The medieval warming period that occured 800-1300 AD was not a global event. In the medieval warming period changes in ocean currents led to warmer than usual climates in Europe but colder than usual climates were experienced elsewhere such as Central America.

Well, at least you used the quotation marks correctly.

wow!
If the reefs are destroyed, you have huge, global events and conditions to worry about, playing with little frags will be the smallest of your concerns.

I doubt GW.
This why: I live in tahiti French Polynesia and we have got a cooling trend in the Southern Pacific for a few years.
This years NZ summer is quite too cool, even for the Caledonians out there.
I made a nice encounter with a Mommy Humpback Whale feeding her baby in the Lagoon on Nov 15, 2007, while usally the whale season here goes from June to Halloween.
I have a bad feeling about the GW fear being promoted over and over by Nuclear industry until most people accepts a fresh start in the Nuclear energy production as a means to avoid GW.
In my view nuclear energy is much more dangerous to life on earth (and Sea) than A few hypothetical additional °C (that already ocurred in the Past without destroying life on Earth.
