WWF Coral Scare
Rising water temperatures, sea levels and acidity in the vast region threaten to destroy reefs in Southeast Asia's Coral Triangle, a region labelled the ocean's answer to the Amazon rainforest, the WWF report said. Saving the Coral Triangle will require countries to commit to deep cuts in carbon gas emissions when they gather for global climate talks in the Danish capital Copenhagen in December to work out a successor agreement to the Kyoto Protocol.
Cuts of 80 per cent below 1990 levels by 2050 would be needed to avert the worst effects...
Collapse of the reefs would send food production in the region plummeting by 80 percent and imperil the livelihoods of over 100 million people

CO2, GLOBAL WARMING AND CORAL REEFS:
by Dr. Craig D. Idso (.pdf)
...The persistence of coral reefs through geologic time – when temperatures were as much as 10-15°C warmer than at present, and atmospheric CO2 concentrations were 2 to 7 times higher than they are currently – provides substantive evidence that these marine entities can successfully adapt to a dramatically changing global environment.
Thus, the recent die-off of many corals cannot be due solely, or even mostly, to global warming or the modest rise in atmospheric CO2 concentration over the course of the Industrial Revolution.
The 18- to 59-cm warming-induced sea level rise that is predicted for the coming century by the IPCC – which could be greatly exaggerated if predictions of CO2-induced global warming are wrong – falls well within the range (2 to 6 mm per year) of typical coral vertical extension rates, which exhibited a modal value of 7 to 8 mm per year during the Holocene and can be more than double that value in certain branching corals. Rising sea levels should therefore present no difficulties for coral reefs. In fact, rising sea levels may actually have a positive effect on reefs, permitting increased coral growth in areas that have already reached the upward limit imposed by current sea levels.
The rising CO2 content of the atmosphere may induce changes in ocean chemistry (pH) that could slightly reduce coral calcification rates; but potential positive effects of hydrospheric CO2 enrichment may more than compensate for this modest negative phenomenon.
Theoretical predictions indicate that coral calcification rates should decline as a result of increasing atmospheric CO2 concentrations by as much as 40% by 2100. However, real-world observations indicate that elevated CO2 and elevated temperatures are having just the opposite effect.
In light of the above observations, and in conjunction with all of the material presented in this review, it is clear that climate-alarmist claims of impending marine species extinctions due to increases in both temperature and atmospheric CO2 concentration are not only not supported by real-world evidence, they are actually refuted by it.
