One of the favorites in the climate blame-game is the alleged dying off of coral reefs due to global warming from man-made CO2..

But that is turning out to be false, too. The online Frankfurter Allgemeine Zeitung writes today that climate change is not responsible for the dying off of the Caribbean coral reefs after all, citing a new report by the International Union for the Conservation of Nature (IUCN).

The IUCN writes (emphasis added):

Climate change has long been thought to be the main culprit in coral degradation. While it does pose a serious threat by making oceans more acidic and causing coral bleaching, the report shows that the loss of parrotfish and sea urchin – the area’s two main grazers – has, in fact, been the key driver of coral decline in the region. An unidentified disease led to a mass mortality of the sea urchin in 1983 and extreme fishing throughout the 20th century has brought the parrotfish population to the brink of extinction in some regions. The loss of these species breaks the delicate balance of coral ecosystems and allows algae, on which they feed, to smother the reefs. [...]

‘Even if we could somehow make climate change disappear tomorrow, these reefs would continue their decline,’ says Jeremy Jackson, lead author of the report and IUCN’s senior advisor on coral reefs.”​

Surprise. Another climate myth gets debunked.

Er, the Parrotfish and sea urchin were killed off because of ManMade Global Climate Disprution!

Denier!!

AGW AKBAR!!!!!


DEATH TO THE DENIERS!!!

Nope.. Gotta be Global Warming. Either that 0.5degC or that 0.1 pH change..
I ain't buying no Exxon funded science on this..


Seriously, watch the 8minute video on that page.. It's back to the good ole days of special interests ruining the environment and
we can oppose them and turn things around.. Hope springs ....... That the enviro movement will quit preaching doom and destruction and hopelessness and get back to work...

:up:

Science and environmentalism IS BACK IN STYLE !!!!!!

The loss of the urchin and decline of the parrotfish are both old news. The same is true of their impact of their decline on coral reefs. Coral and algae benefit from a rather delicate and complex symbiosis. Their are corals that have died from high temperatures, but I have not heard charges that the Caribbean reefs are dying from climate change.

Here is the opening paragraph of Wikipedia's article "Environmental Issues with Coral Reefs

Coral reefs are dying around the world.[1]

Human impact on coral reefs is significant. Coral reefs are dying around the world.[1] In particular, coral mining, pollution (organic and non-organic), overfishing, blast fishing and the digging of canals and access into islands and bays are serious threats to these ecosystems. Coral reefs also face high dangers from pollution, diseases, destructive fishing practices and warming oceans.[2] In order to find answers for these problems, researchers study the various factors that impact reefs. The list of factors is long, including the ocean's role as a carbon dioxide sink, atmospheric changes, ultraviolet light, ocean acidification, biological virus, impacts of dust storms carrying agents to far flung reefs, pollutants, algal blooms and others. Reefs are threatened well beyond coastal areas.

IUCN - From despair to repair: Dramatic decline of Caribbean corals can be reversed



The results show that the Caribbean corals have declined by more than 50% since the 1970s. But according to the authors, restoring parrotfish populations and improving other management strategies, such as protection from overfishing and excessive coastal pollution, could help the reefs recover and make them more resilient to future climate change impacts.
“The rate at which the Caribbean corals have been declining is truly alarming,” says Carl Gustaf Lundin, Director of IUCN’s Global Marine and Polar Programme. “But this study brings some very encouraging news: the fate of Caribbean corals is not beyond our control and there are some very concrete steps that we can take to help them recover.”

The report also shows that some of the healthiest Caribbean coral reefs are those that harbour vigorous populations of grazing parrotfish. These include the Flower Garden Banks National Marine Sanctuary in the northern Gulf of Mexico, Bermuda and Bonaire, all of which have restricted or banned fishing practices that harm parrotfish, such as fish traps and spearfishing. Other countries are following suit.
“Barbuda is about to ban all catches of parrotfish and grazing sea urchins, and set aside one-third of its coastal waters as marine reserves,” says Ayana Johnson of the Waitt Institute’s Blue Halo Initiative which is collaborating with Barbuda in the development of its new management plan. “This is the kind of aggressive management that needs to be replicated regionally if we are going to increase the resilience of Caribbean reefs.”
Reefs where parrotfish are not protected have suffered tragic declines, including Jamaica, the entire Florida Reef Tract from Miami to Key West, and the U.S. Virgin Islands.

The days of blaming GW for every enviro crisis are numbered. We WILL start to solve these issues once science is allowed to operate properly. In the words of the lead author, "the days of doing nothing are over".............

But these do:

Coral Reefs ? Global Issues
The above-mentioned Status of Coral Reefs Around the World, 2004 also notes (p. 21) that “The major emerging threat to coral reefs in the last decade has been coral bleaching and mortality associated with global climate change.”

--

Additional scientific research, reported by Greenpeace fears climate change will eliminate reefs from many areas:

If climate change is not stopped, coral bleaching is set to steadily increase in frequency and intensity all over the world until it occurs annually by 2030—2070.

This would devastate coral reefs globally to such an extent that they could be eliminated from most areas of the world by 2100. Current estimates suggest that reefs could take hundreds of years to recover. The loss of these fragile ecosystems would cost billions of dollars in lost revenue from tourism and fishing industries, as well as damage to coastal regions that are currently protected by the coral reefs that line most tropical coastlines.​

Extinction of coral reefs | Natural History Museum
Extinctions of marine organisms are not as well-documented as extinctions of land-living animals. But that does not make them less important.

The oceans are home to 230,000 known kinds of life, but scientists think that as many as 80% of species on the planet may yet be undiscovered, the majority of which live in the ocean. Until we identify more of these species, we will not know how many of them are becoming extinct due to global warming.​

WWF - Impacts of global warming on corals
One of the most visually dramatic effects of climate change on corals has been bleaching. When the ocean warms, the oxygen content reduces, and corals become ‘bleached’.

The heat affects the tiny algae which live symbiotically inside the corals and supply them with food. The heat stress damages the algae and in consequence leads to coral death.

Global warming could now mean a death sentence for many coral reefs. If the present rate of destruction continues, most of the world's coral reefs could be killed within our lifetime.​

Your limited worldview does not define reality.
 
So Crick is a damned liar.

Not at all surprising, really. And it'll be entertaining to watch him squirm and blame his lies on BIG OIL. :rofl:

That does NOT support this contention: "One of the favorites in the climate blame-game is the alleged dying off of coral reefs due to global warming from man-made CO2."

As can be seen from this Wikipedia text as well as the text of the IUCN article on which the lead post is based IUCN - From despair to repair: Dramatic decline of Caribbean corals can be reversed and the Status and Trends of Caribbean Coral Reef, 1970-2012, http://cmsdata.iucn.org/downloads/executive_summary_caribbean_status_report_eng.pdf coral reefs are endangered by a number of threats. The posts of mine that FCT looked up were discussions on the reality of ocean acidification. The point under discussion there was whether or not acidification was taking place, whether or not it was due to anthropogenic CO2 emissions and whether or not it presented a threat to carbonate fixing organisms (such as coral). I see and admit that more than one of the references I cited contend that the world's coral reefs are threatened by AGW; primarily from acidification but also from temperature increases.

From the IUCN article, emphasis mine:

Climate change has long been thought to be the main culprit in coral degradation. While it does pose a serious threat by making oceans more acidic and causing coral bleaching, the report shows that the loss of parrotfish and sea urchin – the area’s two main grazers – has, in fact, been the key driver of coral decline in the region.

And from Caribbean Coral Reef report:

We caution that our results do not mean that extreme heating events are unimportant drivers or coral mortality due to coral bleaching and disease, as they clearly have been in the USVI, Puerto Rico, the Florida Keys and elsewhere. Moreover, increasingly severe extreme heating events will pose an even greater threat to coral survival in future decades.

If present trends of decreased pH continue, however, the ability of coral and other calcareous reef species to deposit skeletons will be increasingly compromised


I would also point out that parrotfish populations have declined due to overfishing and that the unnamed disease that obliterated sea urchin populations first appeared within less than a kilometer of the Atlantic terminus of the Panama Canal - ie, it was brought to the area by shipping. So do not attempt to pretend that the damage Caribbean corals have suffered in the last four decades is another of your "natural cycles".

The point being that AGW is NOT responsible for the loss of coral.

All we know for sure is that the AGWCult Models say that overfishing is due to ManMade Global Climate Disruption
 
The point being that warming and acidification are still a threat to calcareous marine biota (no suggestion otherwise appeared anywhere in the reference documents and the converse was clearly stated in multiple locations) and that the severe decline of Caribbean corals is NOT the result of any "natural cycle".

There is also the point made in the source material that this issue with parrotfish and sea urchins is unique to the Caribbean and that the Caribbean's isolation due to the isthmus of Panama and the spread of the Atlantic at the MAR give it a range of unique species and almost no chance that repopulation can take place from remote locations.

:lol:

Yes..it's some unidentified disease...



That just makes so much sense!
 
Take 2 fish tanks each with coral and sea urchins. In the second tank add 120PPM CO2 to the air above the tank. According to the AGWCult, the water in the second tank should warm and turn to gastric juice destroying the coral and turning the sea urchin to sushi
 
Yes..it's some unidentified disease...

That just makes so much sense!

What do you think would make more sense?

From:
http://jrscience.wcp.muohio.edu/FieldCourses00/PapersMarineEcologyArticles/MassMortalityinDiademaant.html

THE EPIDEMIC

The occurrence of unusual mortality of Diadema was first observed in mid-January, 1983, on the Caribbean coast of Panama, close to the mouth of the Panama Canal (Lessios et al. 1984). Death appeared to occur rapidly, soon after symptoms appeared, and virtually all individuals died. Affected organisms initially developed an accumulation of sediment, and lost pigment and some spines. As the disease progressed, the animals were unable to remain attached to their substrates. Eventually, they literally seemed to fall apart. Behavioral changes were also noted, as the animals did not typically seek shelter during daylight, and were observed being preyed on by fish not normally seen feeding on healthy Diadema. Within days of the first observation of the disease, most individuals in this population were dead, reduced to bleached tests.

After a lag of several months, the disease was noted in other locations. First affected were Diadema in the San Blas Islands of Panama. Populations across the Caribbean were eventually affected by this spreading disease, which traveled in a pattern consistent with major surface currents. The disease moved from Panama in both a westward and an eastward direction on these currents. The disease spread at a rate of roughly 2000 km/ yr to the east, and nearly 3000 km/yr to the west (Lessios 1988a). Eventually, the entire Caribbean was involved, as the disease spread to Florida and north to Bermuda. 3.5 million square kilometers of ocean habitat were affected, and it does not appear that any population of D. antillarum in this area escaped massive mortality. Populations of this species in the eastern Atlantic, and a sibling species in the Eastern Pacific were apparently not affected. The Pacific species might be assumed to be at risk due to potential transmission of the pathogen through the canal. In practice, such movement of organisms appears to be very rare, probably due to the fresh-water nature of the canal, and the fact that water flows from the continental divide at the high point of the canal out into both oceans.

The disease was not only widespread, but highly virulent. The actual intensity of the disease across the 3.5 million square kilometers affected is difficult to compare, due to variations in sampling protocol, but Lessios (1988a) reports that mortality averaged 98%, exceeding 93% at all locations examined, and ranging to over 99.9%. The disease seemed to stop affecting urchins in February, 1984, roughly one year after it appeared. It did re-appear, however, in October-December of 1985. At this time, the disease seemed much less virulent, with less than 1% of the surviving populations in affected Panama and St. Croix developing symptoms.

No causative agent for the disease has been conclusively identified. Lessios (1988a) cites strong circumstantial evidence that a waterborne, host-specific pathogen was responsible. This evidence includes the tendency of the outbreaks to follow the direction and speed of water currents, the involvement of captive Diadema populations in aquaria fed by seawater, lack of decrease in the mortality with distance, development of symptoms when healthy individuals were experimentally exposed to affected animals, and the apparent limitation of the disease to a single species. Two species of spore-forming Clostridium were cultured from an affected population of urchins (Bauer and Agerter 1987). Healthy individuals died when injected with these bacteria, but the connection between the epidemic and these bacteria was not considered conclusive. Mortality appeared to be density independent. Overall, there does not seem to have been a significant relationship between initial population density and the intensity of the die-off at individual locations (Lessios 1988a).
