A mystery that is a mystery to Warmists only
In science, when something shows your theory is wrong, you change your theory. In Warmism, if something shows your theory is wrong, it's a "mystery". The finding below shows that coral deaths presently being attributed to warming are NOT produced by warming
AN ancient coral reef specimen now on display at the Natural History Museum in London is at the centre of a global warming mystery spanning 160 million years.
THE exhibit is proof that ancestors of modern corals somehow thrived during the Late Jurassic period when temperatures were warmer and atmospheric levels of carbon dioxide higher than they are today.
Yet global warming in the 21st century is already associated with serious damage to coral reefs caused by "bleaching".
Dr Ken Johnson, coral reefs researcher at the London museum, said: "By researching historical fossil corals like this, we can understand and predict the impact of climate change and other environmental factors on coral reefs over time.
"This 160-million-year-old specimen is an ancestor of some of the corals on our planet today, showing us that a sustainable future for coral reefs is possible because they can survive severe global environmental changes."
Early corals also managed to survive the mass extinction at the end of the Cretaceous period 65 million years ago that wiped out the dinosaurs and many other species.
If greenhouse gas emissions continue unchecked, atmospheric carbon dioxide is expected to match Late Jurassic levels by 2100 and to exceed them by 2250.
Bleaching occurs when stressful environmental conditions cause corals to expel the symbiotic algae living in their tissues, turning them white.
Corals depend for their survival on the algae, which provide them with oxygen and nutrients. When they bleach they begin to starve.
Professor Richard Twitchett, palaeoecology researcher at the Natural History Museum, said: "At the time this coral reef was alive, 160 million years ago, our planet's marine biodiversity was as high as it had ever been.
"The fact that this coral reef lived in a much warmer world shows that if we monitor and control future changes, coral reefs can remain one of the most important ecosystems on Earth."

Australian Federal minister Takes To Twitter To Threaten Green Groups Will Lose Their Charity Status
Federal Queensland Liberal-National Party politician George Christensen has issued what appears to be a veiled threat to non-government organisations to “get the donations in” before a committee he sits on strips environmental charities of their tax-exempt status.
Yesterday, the National Party Deputy Whip grilled environmental groups in the first of a series of public hearings which the House of Representatives Standing Committee on the Environment will stage as it considers whether to strip environmental organisations from receiving tax-free donations.
The Queensland Minerals Council - which has allied itself to Christensen in the debate over how huge new coal mines in the Galilee Basin will affect the Great Barrier Reef - appeared first, yesterday morning.
Then Christensen turned his attention to environmental groups, who he described as “morons” during a technical exchange over whether land should be considered to be part of the Great Barrier Reef’s ecosystem.
Felicity Wishart from the Australian Marine Conservation Society was interrogated by the Queensland MP, whose electorate takes in a swathe of coastline adjacent to the Great Barrier Reef.
“He was questioning me about our commitment to accurate information that wasn’t misleading and then trying to grasp at straws and find something that we had done that was misleading,” Wishart told New Matilda.
The Marine Conservation Society had used an image in its campaign material which superimposed a ‘grab dredger’ over the Calley Valley Wetlands and an image of Abbot Point Port, 25km north of Bowen.
Reportedly, Christensen’s main gripes were that the wetlands are ‘not part of the reef’, and the type of dredge to be used for the Abbot Point Port expansion was ‘suction dredger’, not a ‘grab dredger’.
While maintaining the wetlands are an important part of the reef’s ecosystem, Wishart said that the image of a grab dredger was a metaphor for the “one million cubic metres of dredge spoil… that was to be dumped on the wetlands” under previous plans.
After grilling Wishart about the integrity of her organisation’s campaigning, Christensen took to Twitter insisting “they were caught out fibbing, and the committee will sort these sort of lies out”.
The Australian Marine Conservation Society denounced Christensen for “unparliamentary” behaviour, accusing him of “announcing the outcome of the inquiry before it has concluded”, but Christensen said he was “just reading the tea leaves”.
Christensen has previously attacked “gutless green grubs” and “eco-terrorists” for campaigning to win more stringent protections for the reef and battling against an increase in Queensland’s coal exports, which would pump out emissions roughly equal to those created by the United Kingdom, South Africa, or Italy.
The Member for Dawson, who has questioned widely accepted understandings of climate science, has a history of Tweet-controversy. Last month he was forced into an apology over comments linking the American right to bear arms with a recent court decision which legalised marriage equality across the US.
Yesterday, at the inquiry, groups like the AMCS got the distinct impression Christensen was pressing the gun harder to their temples.
“This sounds very much like a government member of the Inquiry threatening environment groups who have been vocal about issues like dredging, dumping and increased shipping in the Reef’s waters,” said Wishart, who acts as a Great Barrier Reef Campaign Director.
In late March, Wishart’s work was singled out as part of a pack of “extreme greens” working for organisations like “Greenpeace, the Australian Marine Conservation Society, Friends of the Earth, Get Up, and the Environmental Defenders Office” who Christensen said “act like Wormtongue from The Lord of the Rings”.
“That is treason,” Christensen told Parliament, “flying overseas and whispering in the ears of the decision-makers and diplomats who have anything to do with UNESCO and the World Heritage Committee, poisoning their minds on the state of the reef”.
“What treachery,” Christensen said, “to go against the interests of your own nation and your own people for no sound reason at all!”

NOAA's estimate of coral bleaching likely two times too high
Written by Thomas Richard
NOAA sounded the alarm yesterday that coral reefs are dying off at an unprecedented rate, even though a recent paper shows that these statements may be more alarmist than accurate. coral bleachingThe National Oceanic and Atmospheric Administration (NOAA) said multi-yearwarm ocean temperatures are creating conditions that are causing corals to die off and turn white (bleached), and they believe that global warming is the culprit. But a new paper, published in Marine Biology in April 2015, shows that even though some corals appear bleached, it doesn't mean they are dead, as conventional tracking methods can't distinguish between white and bleached (dead) colonies.
The paper, by Cruz et al, says that "although bleaching leaves the coral skeleton visible under its transparent tissue, not all white coral colonies display this feature," which "raises the question as to whether all 'white'-shaded colonies are indeed bleached." To answer that question of whether bleached coral is actually dead, Cruz et al studied different colored specimens of the coral M. cavernosa sampled off the east coast of Brazil, and found thatwhite corals exhibited the same lifelike features as their multi-colored cousins.
Simply put, white corals were physiologically healthy when compared to dark and light-brown colonies, which would lead to the "potential overestimation of coral bleaching" by nearly twice as much. One reason for this overestimation is that traditional coral monitoring is unable to detect between white and bleached (dead) colonies. Video transects from reef monitoring surveys off the coast of Brazil showed that the "proportion of bleached and white colonies is similar, thus suggesting that current coral reef surveys may be overestimating the bleaching of M. cavernosa by nearly twofold."
That didn't stop Mark Eakin, NOAA's Coral Reef Watch coordinator, from saying, "The bleaching that started in June 2014 has been really bad for corals in the western Pacific. We are worried that bleaching will spread to the western Atlantic and again into Hawaii." The announcement from NOAA appears to be part of the Obama administration's ongoing campaign to attribute global warming to any event as it gathers commitments from other countries ahead of the Paris Climate Talks.
NOAA also added that only warm ocean temperatures can cause the widespread bleaching that monitoring has found since last year, but this new paper also contradicts that statement. Coral bleaching, the paper says, "is a physiological mechanism triggered by environmental stress, such as elevated temperature, changes in salinity, high solar radiation, pollutants or diseases." They note that "although bleaching leaves the coral skeleton visible under its transparent tissue, not all white coral colonies display this feature."
Once corals die, they turn "white" and have a bleached appearance. But other studies have shown corals are more resilient then previously estimated. One 13-year study of coral reefs showed "them spontaneously recovering," refuting the "often doomsday forecasts about the worldwide decline of the colorful marine habitat." Tom Frazer, professor of aquatic ecology at the University of Florida and part of the research team, told Reuters, "People have said these systems don't have a chance. What we are saying is: 'Hey, this is evidence they do have a chance.'"
One study—funded by NOAA—shows that coral reefs could even adapt to warmer ocean temperatures through a variety of processes. Even after the great coral die-off in 1998 from a particular brutal El Niño, most of the coral reefs across the planet rebounded to their original numbers.
This isn't the first time that NOAA has used dubious data to justify global warming alarmism. In early June, NOAA rewrote the historical climate record by making it "cooler" so the present appears warmer. Even climate scientists who believe that man is primarily responsible for the planet warming less than one degree Celsius over the last 100 years rejected NOAA's readjustments to hide the 18-year-and-counting global warming hiatus.
