Coral Triangle could die by century's end: WWF

WWF said climate change could wipe out the world's richest ocean wilderness by the end of the century
Various kinds of corals grow in the marine protected area of Honda Bay located in Palawan island in western Philippines, 2008. Environmental group WWF said that climate change could wipe out the world's richest ocean wilderness by the end of the century without drastic cuts in greenhouse gas emissions.

Coral reefs could disappear entirely from the Coral Triangle region of the Pacific Ocean by the end of the century, threatening the food supply and livelihoods for about 100 million people, according to a new study from World Wildlife Fund.

Averting catastrophe will depend on quick and effective global action on climate change coupled with the implementation of regional solutions to problems of over-fishing and pollution, according to The Coral Triangle and Climate Change: Ecosystems, People and Societies at Risk, a WWF-commissioned study presented at the World Oceans Conference in Manado, Indonesia today.

"This area is the planet's crown jewel of coral diversity and we are watching it disappear before our eyes," said Catherine Plume, Director of the Coral Triangle Program for WWF-US. "But as this study shows, there are opportunities to prevent this tragedy while sustaining the livelihoods of millions who rely on its riches."

The report offers two dramatically different scenarios for the Coral Triangle, which is comprised of the coasts, reefs and seas of the countries of Indonesia, the Philippines, Malaysia, Papua New Guinea, the Solomon Islands and Timor Leste. The Coral Triangle occupies just one percent of the Earth's surface, but is home to fully 30 percent of the world's coral reefs, 76 percent of reef-building coral species and more than 35 percent of coral reef fish species. It is also serves as vital spawning grounds for other economically important fish such as tuna.

"In one scenario, we continue along our current climate trajectory and do little to protect coastal environments from the onslaught of local threats," said Queensland University Professor Ove Hoegh-Guldberg, who led the study. "In this world, people see the biological treasures of the Coral Triangle destroyed over the course of the century by rapid increases in ocean temperature, acidity and sea level, while the resilience of coastal environments also deteriorates under faltering coastal management. Poverty increases, food security plummets, economies suffer and coastal people migrate increasingly to urban areas."

The report also highlighted opportunities to avoid a worst-case scenario in the region through significant reductions in greenhouse gas emissions and international investment in strengthening the region's natural environments, solutions that would help to build a resilient and robust Coral Triangle in which economic growth, food security and natural environments are maintained.

"Climate change in the Coral Triangle is challenging but manageable, and the region would respond well to reductions in local environmental stresses from overfishing, pollution, and declining coastal water quality and health," Hoegh-Guldberg said.

Even under the best case scenario however, communities in the region can expect to experience dramatic losses of coral, rising sea level, increased storm activity, severe droughts and reduced food availability from coastal fisheries. But effective management of coastal resources would mean the communities would remain reasonably intact and more resilient in the face of such hardships.

WWF officials said world leaders have a role to play in helping Coral Triangle countries strengthen management of their marine resources and through international action on climate change.

"We must forge a strong international agreement to bring about sharp reductions in greenhouse gases at the UN Climate Conference at Copenhagen in December," Plume said.

At the rate that our oceans are cooling I bet that the corals will freeze to death by mid-June 2097. /- a month.

CO2, GLOBAL WARMING AND CORAL REEFS:
by Dr. Craig D. Idso (.pdf)

...The persistence of coral reefs through geologic time %u2013 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 %u2013 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.

What more can you say? Forget "Climate Change" and concentrate on polution.

Exactly but please add in a little for education :)

Sorry for repeat. The site was very slow, so I cancelled and tried again later. Seems both took.

Standing back a bit, I notice that corals have been around for millenia. I seriously doubt that they will disappear forever.
Now, humanity? Perhaps.

[Q]"WWF officials said world leaders have a role to play in helping Coral Triangle countries strengthen management of their marine resources and through international action on climate change."[/Q]

If that's true, why don't the elitist just tell teh "world leaders" to do so? I expect this is yet another scam to increase taxes on emissions rather than make any efforts to reduce pollution.
