German language RTV here reports: All the talk in the media of a dying Great Barrier coral reef near Australia is “a media swindle”.

The facts: Record numbers of coral reefs were already measured in 2024 and the coverage has indeed tripled over the last 12 years.
According to RTV, “coral bleaching due to high water temperatures has been proven to be a lie” and the claim of damage to the reef in recent years said to be due to climate change has in fact a completely different background and has the reef has recovered.
According to Report 24, all the media claims made on a yearly basis, e.g. from the Guardian and CBS, of the Great Barrier reef near Australia dying at a record speed and being irreversible is “a fairy tale” and “false, misleading or simply a lie.”
Report 24 writes that the damage to the reef was caused by a tropical cyclone that moved across across the reef in 2009 and caused immense damage. A study by the Australian Institute of Marine Science summarized the damage which ranged from exfoliation, scouring, which removed all living tissue from the corals, and included coral breakage where both massive coral heads and more fragile branching corals broke off.
It had nothing to do with CO2 and climate change.
Moreover, according to scientists, coral bleaching is by no means a sign of a dying reef and does not produce a white dead coral lump like the ones you can buy in a souvenir shop on the beach. Instead, bleaching means that the coral has lost the algae living in it, usually due to various stress factors such as fluctuations in light or changes in water temperature. This causes the living coral to turn white but not necessarily die.
Report 24 adds that occurrences of coral bleaching could become even more frequent due to the record growth of recent years.
The dying reef narrative began 12 years ago when the reef was severely damaged by the cyclone, with up to 85% of the coral cover gone. At the time, real scientists stated that recovery could take up to 15 years, and this is exactly what has since happened.
The reef has not only recovered, but also continued to expand.
Thanks.

“the Great Barrier reef near Australia dying at a record speed and being irreversible is “a fairy tale” and “false, misleading or simply a lie.”
The reason is/ was(will be) pushed is to destabilise public opinion eg create a problem and present a solution (more control).
“the Great Barrier reef near Australia dying at a record speed and being irreversible is “a fairy tale” and “false, misleading or simply a lie.”
Why then should this fairy tale be pushed???

Coral bleaching is analogous to evolution… it’s not a sign that the coral is dying, it’s a sign that the coral is swapping out less-fit symbiotic organisms for more-fit symbiotic organisms.
The whole “CO2 is killing the corals and It’s All Your Fault” narrative is based upon lies.
For instance:
https://www.surfrider.org/news/washington-state-re-ups-leadership-in-addressing-ocean-acidification
“Global carbon dioxide (CO2) emissions over the past two centuries have altered the chemistry of the world’s oceans, threatening the health of coastal ecosystems and industries that depend on the marine environment.”
“Calcifiers are marine organisms that depend on the mineral calcium carbonate to make shells, skeletons, and other hard body parts. Ocean acidification makes an essential component of calcium carbonate – the carbonate ion – more scarce. As a result, calcifiers have to use more energy to pull carbonate ions out of the water to build their shells. Calcium carbonate also dissolves more easily as acidity increases. These changes can result in slower growth and/or higher mortality among calcifiers, especially in shellfish larvae and juvenile shellfish.”
Corals and mollusks, which evolved during the Cambrian Explosion which had many times higher CO2 concentration (which was arguably the cause of the Cambrian Explosion), evolved no carbonate transporters, instead evolving bicarbonate transporters… because as CO2 concentration rises, ocean pH falls which means carbonate practically disappears at ~pH6, whereas as CO2 concentration rises, ocean bicarbonate concentration rises, thus that makes it easier for coral and mollusks to undergo the calcification process. Calcification is currently rate-limited because atmospheric CO2 concentration is nearly at historic lows, and thus oceanic bicarbonate concentration is comparatively low.
IOW, if you want to ‘save the corals’, emit more CO2.
But all of the “muh CO2 bad” blather about CO2 harming corals is predicated upon the corals using carbonate transporters. To date, several bicarbonate transporters have been found across a wide taxa of corals and mollusks, whereas no carbonate transporters have been found.
[1] CO2 (carbon dioxide) + H2O (water) ==> H2CO3 (carbonic acid)
[2] Aqueous: H2CO3 (carbonic acid, from [1]) ==> H+ (hydrogen cation) + HCO3- (bicarbonate anion)
[3] In-vivo: Bicarbonate transporter transports HCO3- (bicarbonate anion, from [2]) across cellular membrane
[4] In-vivo: HCO3- (bicarbonate anion, from [3]) ==> CO3-2 (carbonate anion) + H+ (hydrogen cation)
[5] In-vivo: CO3-2 (carbonate anion, from [4]) + Ca+2 (calcium cation, dissolved in water) ==> CaCO3 (calcium carbonate)
[6] In-vivo then excreted: H+ (hydrogen cation, from [4]) + H2O (water) ==> H3O+ (hydronium cation)
Yes, coral and mollusks excrete acid.
pH = −log_10 [H+]
And that excreted H3O+ (hydronium cation, from [6]) then goes on to interact:
[7] Aqueous: H3O+ (hydronium cation, from [6]) + CO3-2 (carbonate anion, dissolved in water) ==> H2CO3 (carbonic acid) + OH- (hydroxide anion)
[8] Aqueous: H2CO3 (carbonic acid, from [7]) ==> H+ (hydrogen cation) + HCO3- (bicarbonate anion)
[9] Aqueous: OH- (hydroxide anion, from [7]) + H+ (hydrogen cation, from [2] or [8]) ==> H2O (water)
You’ll note that the hydronium (H3O+) cations actively scavenge carbonate anions (CO3-2) (which the coral and mollusks cannot use) and coverts them into carbonic acid (H2CO3), which then undergoes the first aqueous reaction above to convert to H+ (hydrogen cation) and HCO3- (bicarbonate anion… which the coral and mollusks can use).
Kind of strange that coral and mollusks can handle the extreme acid of undiluted H+, and H3O+ (the strongest acid that can exist in water), but purportedly they can’t handle a tiny change in ocean pH, despite evolving at a time when atmospheric CO2 concentration was many times higher than today and thus the ocean was less alkaline.
Almost as if we’re being lied to. Hmmmm…
