This video is part of a story at http://climateXchange.aspacnet.org/story_64.html
Corals get up to 90% of their energy supply from the zooxanthellae that live within them. Stressful conditions (including high water temperature) cause the corals to expel their zooxanthellae. Bleached corals begin to starve once they bleach.
The Great Barrier Reef has been affected by mass bleaching events. Widespread bleaching occurred in 1998 and again in 2002. In both of these years, bleaching was recorded on 50-60 per cent of reefs.
More recently in the summer of 2006, reefs in the southern part of the Great Barrier Reef were affected by bleaching. Unusually high sea temperatures around inshore reefs caused 40% of corals to die at these reefs.
We can all make a difference to the health of the reef by minimising our contributions to climate change by reducing our greenhouse gas emissions.

Sidd, That's a really neat setup. My tank and is only about 6 tmonhs old and i know i still have a long way to go. I was almost convinced that i need to add chemical supplements to keep it running but thats changed after reading your post.I still... read more » | |

Dec 17, 2009 - that's just what the major oil companies and mining industries want you to believe. There's much more evidence for climate change occuring then there is against it. Plus studies against climate change occuring is usually paid for by industries that will benefit from this. Such studies are not usually even published in scientific journals where they can be critiqued by other scientists.

Dec 28, 2009 - Only in America. Meanwhile in the rest of the Western world (who are, curiously, more science literate - look it up) are deciding on the proper course of action to prevent further social and ecological problems, than those already being caused. Yes that's right. That media anti-science bullshit you get in the USA ... that's called "politics" ... and it's because your media is corporate owned. Run by money, to protect money.

Apr 6, 2010 - i understand global warming is devastating coral reefs such as the great barrier, but wouldnt climate change just relocate the corals else where in the ocean?

May 11, 2010 - eew, no. this is bad, but there are better ways to solve these problems than taking more from the public

Oct 14, 2010 - GREAT VIDEO!!! EDUCATION IS THE KEY TO SAVING OUR REEFS. The Aquarium of Niagara (Niagara Falls, NY) is in the running for a grant through the Pepsi Refresh Project. The goal is to build an educational reef display, as well as start a coral propagation program. In order to get the grant they need people to vote for their project. You can vote by texting 102344 To: 73774 or search "Niagara Reef" for more info. For more info search "Niagara Reef" on Facebook.

Dec 5, 2010 - this was incredibly interesting, so how does he write underwater again?

Dec 7, 2010 - we should stop saying "This could accelerate Global warming" rather its like a "Domino Effect in Climate Change" ... if one piece FALLS most of the other pieces could fall..... one example would be .... during 2003 Europe heat wave plants in Europe actually REVERSED their photosynthesis... it was that hot .... and actually started taking in Oxygen and releasing CO2 in the Air..... more recently millions of "Seashell Storms" on Pakistani beaches daily... check out my video on my page.....

Sep 13, 2011 - Anyone who studies geology will tell you life has been living through hundreds of millions of years of temperature changes and there have been numerous occasions where mass extinctions have taken place, however we humans, along with lots of other animals, are still here today. global warming will not kill everything, it will just put stress on the resources we still have unless we act to stop it.

Oct 21, 2011 - For any Australians, please sign this petition in the hope the government will fund renewable energy to achieve zero carbon emissions in the not too distant future - aycc.org.au/repoweraustralia/ (it should be the first link in the search) -thankyou, Australian Youth Climate Coalition. Your interest in this issue will benefit humanity and all other species.

Nov 22, 2011 - wow this is of a major importance !!! but why is she such happy !?
alon nir Says:
Nov 22, 2011 - it takes about 1 year for this corals to grow 1 cm !! think about how fast bleeching happen compared to the growth!

Feb 29, 2012 - Doubt global warming? The oceans are rising an average of 3 millimeters per year, that's directly measurable, confirmed science. Any idiot can confirm it.  Where is this increased volume coming from? I'll give you a hint: it's not coming from space.

Apr 22, 2009 - This is not good. If the reefs vanish, the fish that live in them die. Those small fish supply food to all the other creatures in the ocean. Basically, when you kill the bottom of the food chain, everything above it dies too. LET'S STOP GLOBAL WARMING!!! Happy Earth Day.
