The Great Barrier Reef is Doing Just Fine

It is not a surprise that the data do not support the alarmist narrative.
Mainstream Media Hypes False Claims Climate Change is Killing Coral
CORAL REEFS OCTOBER 8, 2021

" . . . Recent peer-reviewed research described in a Phys.org article, titled “Half a trillion corals: World-first coral count prompts rethink of extinction risks,” should serve to calm any concern for the continued survival and flourishing of corals. The study cited places the number of corals in the Pacific Ocean alone at more than half a trillion. There are likely trillions more worldwide.

The scientists involved in the research say the sheer number of corals and coral species means the risk of extinction due to climate change is vastly lower than previously claimed. . . . "

 

coral bleaching is a natural process that coral uses to survive a rapid environmental change like an El Nino. Coal bleaching sounds horrible but it not. its just the coral expelling the algae in its tissue and either growing a new algae that is better suited to the new environment, or the rapid environmental change goes back to normal and it re grows the same algae it expelled. Coral Bleaching does not mean dead coral. the coral is very much alive still. It can be a stressful time on the coral and there is the possibility of some die off depending on how bad the el nino is. but the coral reef has always been fine after a coral bleaching event.. coral bleaching has happened thousands of times in the past and will happen thousands of times in the future.

All of the climate change worriers out there stop and think about this for a min. Coral Bleaching is an evolutionary adaptation that coral has developed to survive environmental changes.. and the AGW pushers are pointing to coral bleaching as proof that the coral cant survive an environmental change.. let that sink in for a min

 

And you know this how?

 

its what I do for a living.. and this and "ocean acidification" is the reasons I have become a "skeptic" and really started questioning things

GBR, Indian Ocean, South China Sea Corals Have Experienced No Obvious Modern Warming
By Kenneth Richard on 21. October 2021

Share this...
New temperature reconstructions using coral skeletons as proxies reveal there has been no apparent net warming in the Great Barrier Reef, central Indian Ocean, and South China Sea since the 19th century – or even in recent decades.
Coral skeletons can be used as proxies to reconstruct 1870s-present sea surface temperatures “throughout the Great Barrier Reef”. Evidence of dramatic warming aligning with the post-1940s rise in CO2 emissions is absent in the reconstructions.

Remember all the talk about AGW harming the GBR? Never mind.
Great Barrier Reef Warming, Coral Bleaching Driven By Cloud Radiative Forcing, Not Humans
By Kenneth Richard on 2. December 2021

Share this...
For decades Great Barrier Reef (GBR) warming and coral bleaching have often been assumed to be driven by human greenhouse gas emissions and/or El Niño events. But a new study finds a much larger and more robust correlation between natural cloud cover modulation of solar radiation, shallow-water warming, and bleaching.
It has taken over 260 years for the net total radiative forcing from CO2 to allegedly rise by a grand net total of 1.82 W/m².

But a new study reveals that a commonly-observed 20% decrease in cloud cover over the GBR exposes this region to an additional 30 W/m² of direct solar radiation for weeks, months at a time. This dramatically warms shallower waters and, more importantly, the enhanced shortwave radiation perpetually exposes corals to UV bleaching.

“Lagged regional sea surface temperature (SST) is correlated with total cloud cover across the Great Barrier Reef (GBR) and direct shortwave cloud radiative forcing.”
“SST over the GBR is more highly correlated with the overhead cloud cover than the large-scale El Niño–Southern Oscillation signal.”
“Local-scale reduced cloud cover plays a crucial role in the shallow water warming over the GBR and the occurrence of thermal coral bleaching events.”

Aquaculture, literally the breeding of coral.. now you want to address what I said and how it was wrong? I wont hold my breath you have no idea what your talking about here so your only option was to try and attack me personally vs discussing what I actually said..

Science issues expression of concern nine months after one of its reporters uncovers potential misconduct

Danielle Dixson

Science has issued an expression of concern for a 2014 paper on the harmful effects of ocean acidification on fish and coral after the first author of the article was accused of fabricating data in the study and other research.

The article, “Chemically mediated behavior of recruiting corals and fishes: A tipping point that may limit reef recovery,” was written by a group at Georgia Institute of Technology led by Danielle Dixson, then a post-doc at the university. Dixson has since moved to the University of Delaware, Lewes, where she runs her own lab studying corals.

The work – cited 171 times so far, according to Clarivate Analytics’ Web of Science – received immediate challenge from other researchers, who questioned the validity of the findings.

The coral reefs are doing well.
One New Coral Reef Study Wipes Out Four Climate Alarm Narratives In One Fell Swoop
By Kenneth Richard on 24. February 2022

Share this...
Corals thrive in multiple-degrees-warmer-than-today waters and their growth is stunted in cooler environments.
The warnings peddled by climate alarmists often characterize Earth’s 500 billion corals as critically endangered by modern global warming.

But the science itself says corals have been and continue thriving in the Current Warm Period – just as they have in past warm periods.

Within the span of a few pages, one study (Long et al., 2022) squelches at least 4 false climate alarm narratives.

Scientists have determined:

1. Coral reefs “develop rapidly in the warm period” (Roman, Medieval), and “coral reefs develop slowly in the cold period” (Little Ice Age, the Dark Ages Cold Period). Why? Because “warm periods are conducive to coral growth.”
2. Coral reef growth rates have rapidly accelerated in the last 300 years, or since the industrial revolution commenced.
3. Sea levels were 2 meters higher than they are today ~4,000 years ago, and still about 1 meter higher than today 1,000 years ago, or during the Medieval Warm Period. Lower sea levels produce a “decline in the coral reef development rate”.
4. The South China Sea surface temperatures were “3 to 6°C higher than today” from about 5,000 to 4,000 years ago; coral reefs developed rapidly in that warmth.

How much attention will an iconoclastic study like this receive? None, probably. Studies that don’t advance the climate alarm narrative are usually dismissed and ignored. . . .

 

Despite a media blackout, word is spreading that coral reefs are doing just fine -- thriving, in fact.
Study Says the Quiet Part Out Loud, Coral Reefs Doing Fine in Warmer Oceans, Media Blackout in Place
CORAL REEFS MARCH 1, 2022

New research, published in the journal Marine Geology & Quaternary Geology, confirms what previous research highlighted by Climate Realism has shown, coral reefs develop and thrive in warmer seas and are not threatened current warming.

Don’t expect to hear about this good news in the mainstream media reporting on climate change. To find out about the study or its findings, if you are not a subscriber to the journal itself, you have to look to climate realist sites like Climate Change Depot or No Tricks Zone for coverage.

The study confirms that coral thrive in warm waters, growing and expanding their range during warm periods. By contrast, coral colonies shrink and die back during cold periods. . . .

 

The GBR continues to thrive, alarmist nonsense notwithstanding.
Sorry, WaPo, There Is No Evidence Bleaching Threatens a Great Barrier Reef “Tipping Point”
CLIMATE CHANGE IMPACTS MARCH 29, 2022

". . . Data does not support WaPo’s claims about the extent of previous bleaching events in the GBR. Although some scientists widely quoted in corporate media reports on the 2016 bleaching event claimed 93 percent of the GBR suffered bleaching in 2016, subsequent research from the Australian Institute of Marine Science (AIMS) showed just 22 percent of the reef had bleached with AIMS estimating more than 75 percent the bleached coral would recover. As discussed in Climate Realism, AIMS’ survey determined there was “minimal impact” from the 2016 bleaching with hard coral across 85 percent of the reefs expanding year over year.

Indeed, rather than recent bleaching events indicating corals might be approaching a tipping point for the collapse of the reef, AIMS’ survey showed, as late as August 2021 corals were at a historic high for numbers. AIMS reported “Hard coral cover increased across all three regions (Northern, Central, and Southern) and most reefs surveyed had moderate or high coral cover. Overall, 59 out of 127 reefs had moderate (>10% – 30%) hard coral cover and 36 reefs had high (>30% – 50%) hard coral cover.”. . . ."

 

The alarmists are lying, again, about the GBR.
Epicentre of Mass Coral Bleaching – Still So Beautiful (Part 1)

April 11, 2022 By jennifer 11 Comments


It is all over the news, right across the world: the Great Barrier Reef is bleaching – again. Children can’t sleep at night: it is not only the war in the Ukraine keeping them awake at night, but also our apparent disregard for nature.

Except!

On 10th April 2022 I went to the very epicentre of the claimed latest severe mass coral bleaching, and found a coral wonderland.

There was some bleaching, especially around the perimeter of John Brewer Reef – on the sandy sea floor where the Australian Institute of Marine Science (AIMS) surveyed and concluded coral cover is never more than 30% – but most of John Brewer Reef is still covered in more than 80% colourful corals. This high percentage is denied by AIMS because they never survey the reef crest.

This coral reef, John Brewer Reef, has been described as one of the worst bleached by the ABC, The Conversation, and The Guardian. The Guardian uses the same photographs as the ABC which have been sourced from environmental group the WWF.

At John Brewer Reef just yesterday, I swam over the top – over the reef crest – and I also swam along the walls that drop down to the sandy sea floor.

Sorry, CNN, Great Barrier Reef Is Setting Records, Fearmongering Won’t Work

From ClimateREALISM

By H. Sterling Burnett

Excerpt:

A new report from the Australian Institute of Marine Science (AIMS) shows the Great Barrier Reef (GBR) set new records for extent this year. Sadly, in a story titled, “Parts of Great Barrier Reef record highest amount of coral in 36 years,” CNN tried to turn this good news contained in the headline into a climate cautionary tale.

Maybe the climate cult will stop their fearmongering and lying over the reefs?
