Bummer, I'm attempting to plan a trip to dive that early next year.

It will still be there in large part. This is a 10 year old story. Coral bleaching is a world wide problem. Pollution and fresh water runoff are also coral stessors that make it harder for them to deal with warming.
I wtinessed it first hand in my tank when. All iit took was 2 days of 90 degree+ temps and I lost all my sps corals and had to frag my lps to save them. I was out of the country when it happened and had a friend stop by every couple of days to feed.

A little off topic, but sort of related. National Geographic had on a show about the effects of global warming on the glaciers of Greenland. Melting ice has bored holes straight thru the glacier, 1/4 mile down to the bedrock. All this water is providing lubrication for the ice to slide into the ocean. They said there is enough ice in Greenland to raise the ocean level 4 feet worldwide.

Because of the global warming the Polar Bear population could dissapear by 2050 one of the world's largest predators gone. The only place on the planet you would see one would be the zoo.

Yet the guy in the cube next to me has tons of information that Globla Warming is not man-made, but a natural occurnance.

It is a natural occurence, but it should take millions of years to do what we have done is decades. We have contributed to the problem that cycles all by itself with all the CO2 we add to the atmosphere, along with the destruction of the forests that naturally clean it out. Really sad how we have ignored the planet so indiscrimanently.

The "scientific" community denying global warming now reminds me of the "scientific" community denying the ill effects of tobacco in the 70's.
The difference is that anybody can see global warming/climate change with their naked eyes.
That term alone "climate change" makes me mad, as "global warming" is much scarier, and therefore a better motivator to get humans to do something about it. There are very large powerful forces, with lots of money and political influence, which would like us to keep on sucking down oil at the same rate or quicker, regardless of the consequences.
Kyoto now!

"There are very large powerful forces, with lots of money and political influence,"
Correct, on both sides of the equation. To my knowledge there has been no definitive conclusion on the topic. Should we err on the side of caution, perhaps but I've seen as much (if not more) presented scientific evidence of it being cyclical as anything else. When Al Gore has to include digitally created scenes from Hollywood movies in his 'documentary' (and not label them as such), it hurts the cause more than helps it.

What are the very large powerful forces with lots of money and political influence that want us to STOP sucking down oil? Tree huggers? Birkenstock? The Audubahn society? The environmental lobby is quite weak compared to that of big oil and big business.
As to definitive conclusions, I'd cite to international global opinion as manifested by treaties and pacts like the Kyoto Protocol. Defer to the experts as I always say.
But this is all just my opinion. I like the reefs the way they are, well, better the way they were 14 years ago when I was certified. Last summer I returned to where I was trained. A national park (in the ocean) off the coast of the Florida Keys called John Pennycamp State park. The bleaching and overall blandness struck me. To be fair, it's impossible to measure how much is due to global warming, chemicle change, hurricanes, etc.

Well we've got the Al Gore crowd to start with.....
'As to definitive conclusions, I'd cite to international global opinion as manifested by treaties and pacts like the Kyoto Protocol. Defer to the experts as I always say'
I guess you get to decide which scientists are the right ones? I can cite as many on the opposite side of the discussion
'it's impossible to measure how much is due to global warming, chemicle change, hurricanes, etc.'
Where 'etc' = normal cyclical events within the history of the planet

While Al Gore is very large (oh geeze, that was wrong), it's a tough sell that the environmentalists have lots of money and political influence as compared to big oil/business. The status quo is a very powerful force.
I don't decide which scientiests are the right ones, their methods do. Expert scientists who have worked in the field, and followed a strict scientific method have come to almost international solidarity on the issue, once again as manifested by International  treaties and coalistions like the Kyoto protocol, or the United Nations panel on Climate Change. These represent wide swaths of the international demographic, not just interested parties from one geographic location who have financial gain or loss to motivate them.
It is my view and opinion that any "debate" left on the issue, is akin to the "debate" going on in the 70's about whether tobacco was really bad for you. I don't consider the outliers working for big tobacco or big oil "scientists, or experts" regardless of what their curriculum vitae says. I consider them (hmm... how to say this) "painted ladies of the night."
Twalcott it's apparent that we are not going to change each other's minds, so I agree to disagree  , though I do enjoy a good civil discussion/debate  . I'm not even sure we disagree since you've already said it is better to err on the side of caution. You're right, it's not like we can just go somewhere else if this whole "earth" thing doesn't work out.

Agreed, I'd hate to have to list the 600+ accredited scientists and academia who have taken the opposite view. My little fingers would fall off

What's sad is that the world will be fine without us humans (in fact, you know very well the earth would be much better off), but we are only here on this planet for a brief stint of time, and the earth will be just fine when we are gone. The earth is millions of years old and we can try and screw up the planet as much as we want to, but it will survive and still be here when we are gone.
The true problem is that we are killing of species of plants/animals that will not make it back. We are killing things that my grandkids won't have the benefit of enjoying.
Sorry for sounding like a PITA (pain in the ...), but think globally and act locally.

I live in Queensland, Australia and I have recently been diving on the GBR. It's still fantastic diving! Sure the corals are in danger...but why not do coral research WHILE diving?
I am currently working with a professor and scientist at the University of Queensland to produce a DVD to send out world wide about Coral Bleaching and a simple chart designed for coral research. They have also come up with a way (while snorkelling OR diving) to do coral research with a non invasive and simplistic chart.
If anyone is interested, visit coralwatch.org
and any more questions - I have quite an extensive knowledge about coral bleaching and wouldn't mind sharing it with you all!

Heck yeah I'm interested. Why don't you tell us what exactly bleaching is, how it affects corals, what the causes are and how to stop it? After "bleached" can coral return to their natural healthy state? Are some corals immune to bleaching and if so why?

Bleaching is the expulsion of zooanthellae resulting in tissue discoloration (white appearance). Bleaching does not mean a coral is dead since the tissue is still evident, can regenerate, and is a normal occurrence within the oceans and our aquariums. Massive bleaching, stress reaction, can compromise overall health of an ecosystem by depleting nutritional values, forcing the corals to utilize other nutritional means, and decreasing overall disease and predation protection by not being able to produce immunity responses. The causes are numerous and can intertwine, but always stemming from stress. Just about anything you can think of will stress corals, from temperature fluctuations and starvation to disease and predation. Corals that are more sensitive to change, such as Acropora, are more vulnerable to bleaching events.

Zooxanthellae are algae which live in reef-building corals. They supply the nutrients that make it possible for the corals to grow and reproduce quickly enough to create reefs. Zooxanthellae provide the corals with food in the form of photosynthetic products.
Zooxanthellae leave the coral under stressful conditions; heat; low salinity caused by FW runoff; turbity (also from runoff), etc. This causes the coral to lose it's color (bleach) and appear white. Sometimes coral can come back from such events, but sps corals (e.g Acropora) generally do not.
I had this happen in my tank in November 2006 when I was out of the country for a month. I had a friend stopping in every 2-3 days to feed the tank and check on things. I did not comtemplate a mild week of weather so I did not leave a window cracked open as I normally due. Due the lights over the tank the condo got into the 90's for 3 days and so did the tank. I lost all my sps corals, had to frag my leathers and thought I had lost my lps corals too. Some of them did manage a miraculous revival.
