What climate disaster? The Great Barrier Reef has more coral growing on it than ever recorded

The coral cover as sampled by AIMS across the entire Great Barrier Reef is not just good, but better than it has ever been in the 36 years they have been studying it. If the reef is in danger — it’s from being overgrown with coral. Climate Change, such as it is, has caused no trend at all.

If anything, in the spirit of modern-media-science, climate change causes record coral growth.

Tonight the UN scientists decided not to list the reef as “in danger”. The ABC and every Green group who normally follow UN scientists slavishly said that was “only because of lobbying”.

Record Coral Cover on the Great Barrier Reef.

The new AIMS report on Monday showed the Great Barrier Reef had a remarkable recovery, but the graphs were of three different sections of the reef (North, central and South). Peter Ridd obtained all the data and combined it to make one graph and discovered that the coral cover of 2020 was a new all time record high.

Strangely none of the government agencies or paid Professors discovered this. You have to be unemployed to discover record coral growth.

Science and media doomsayers ignore good news on […]

What a recovery! Hottest ever year causes… coral reefs to grow

Life bounces back

The Great Barrier Reef has had a good year. 2020 might have been the hottest or the second hottest year on record, but it was a bonanza year for reef recovery.

The reef covers 344,400 square kilometres, survived the Holocene Optimum, the Minoan warming, the Roman warming and the Medieval Warming, and is already recovering from a streak of few nasty El Ninos and a cyclone or two.

But the bottom line is that coral deaths are not easily relateable or predicted by hot weather or high CO2. If sea level changes or temperature volatility are the real culprits, the ocean currents or cloud cover may be the driver, and not the number of cars or solar panels in Australia.

As Peter Ridd has said for years: The Great Barrier Reef has about the same amount of coral as it did in 1985

Coral Cover, Northern Great Barrier Reef.

 

What a difference a few years makes. Where, here, is there any sign that either CO2 or high temperatures is a problem?

Coral Cover, Central Great Barrier Reef.

 

The trend appeared to be “all down” in 2011, but neither heat nor El […]

Corals bleached in 1862 by all the cars and coal plants that didn’t exist

Peter Ridd writes that a new paper uncovers rare lithographs of corals underwater in 1862.

One hundred and fifty year old pictures of corals are rare enough, but these ones had the unmistakable pure white cauliflower look that marks them as totally bleached. But in 1862 the first coal fired power plant was still twenty years away from starting work as a coral destroyer, and carbon dioxide levels were a perfect 286ppm.

This is the spot (below) in the Northern Red Sea just at the end of “The Little Ice Age”. Perhaps the seas were too alkaline then, and were yet to reach the perfect pH nirvana they must have struck the year before humans started scuba diving en masse.

Bleaching in 1862, twenty years before the worlds first coal fired power plant was built. Ransonnet 1862 | Tomas Cedhagen 2021

We can see why scuba diving was not popular in 1862.

The first underwater camera had a little man inside?

 

Somehow the great marine-psychics of the world know that corals didn’t bleach in the early 1960’s even though, or perhaps “because”, there was almost no one down there to see it.

From Peter Ridd:

Using “Enviromentalism” and the UN as a trade weapon: China fires fake “Reef Scare” missile

Flynn Reef, Queensland, Photo by Wise Hok Wai Lum

Ever since Australia asked for an investigation into the source of Covid, China has been accidentally-on-purpose sticking pins into our trade deals. Pop went the wine, coal, beef, barley and lobster markets.

Now after concreting corals reefs in the South China Sea and plundering the Galapagos, China is suddenly concerned about the Great Barrier Reef. Overnight Chinese players in the UN have pushed it to the top of a list that had 82 more fragile ecosystems ahead of it. Pop, goes the tourism trade as the headlines ring out that UNESCO says the Reef is “in danger”.

At the moment, the only tourists that could possibly be frightened away are a few New Zealanders, because no one else can easily get around the two week quarantine. But when flights reboot, Australia just needs to send photos of the glorious corals to the world and “pop” goes the UN and China’s reputation.

It’s time the West dumped the UN — it’s just a play tool for Sino power

That would “pop” some of the CCP web of influence. What’s a Veto of a dead committee worth?

All reefs look dead from a plane — Great Barrier Reef still alive underwater

Can you spot a dead coral from 120 meters in the air?

The media and academic experts keep telling us the reef is dead. Jen Marohasy points out that the death of the Great Barrier Reef was diagnosed from the sky, so she had the radical idea of going out to reefs like Pixie reef to photograph it underwater instead. She didn’t receive any of the $440m Malcolm Turnbull sent to save the reef. But strangely, none of those millions appears to be used to do something as banal as a swimming near a coral. In an earlier post she described how many of the corals grow in vertical walls, which are very difficult to spot from a plane. Now she’s demonstrating how hard it is to spot even obvious things from a plane.

This reef, Pixie Reef, was ‘surveyed’ back on 22nd March 2016 from the air by Terry Hughes of James Cook University during one of his fly pasts. It was concluded from that single observation/glance-down from 150 metres altitude that that this reef was 65% bleached. The inshore reefs north of Cairns were more or less all written-off, back then, by the experts and the […]

Yet more footage of Great Barrier dying reef not dying

Jen Marohasy went hunting for bleached coral:

What is the true state of the Great Barrier Reef? … In January 2020, Emmy Award winning cameraman Clint Hempsall, and IPA Senior Fellow Jennifer Marohasy decided to find out. They spent a week exploring the Ribbon Reefs 250kms to the north east of Cairns in search of coral bleaching – the process of corals turning white as a result of warmer water temperature, which climate scientists say is being caused by climate change. Some argue 60% of the coral at the Ribbon Reefs was irretrievably bleached in 2016.

Somewhere among 350,000 square kilometers of coral reef, Jen Marohasy had no trouble finding some happy corals, giant cod, and cute nemo fish.

The IPA and the B. Macfie Family Foundation supports and publishes the video:

Colorful corals of the Great Barrier Reef

Don’t believe your lying eyes. Incandescent light globes are killing the corals one by one, air conditioners cause fish to act reckless, and only more solar panels and windmills can save them. You know it makes sense.

Living coral.

Many of the corals grow on vertical formations which are not visible on […]

Global Mystery: Barrier Reef dying, total panic, but no one cares enough to measure growth for last 15 years?

Fifteen years of missing data tells us everything we need to know

Peter Ridd and Jennifer Marohasy are continuing to follow up on the death of the Great Barrier Reef. Strangely, while everyone professes to care, and cry, and Malcolm Turnbull casually tossed half a billion at it, we see the extremely radioactive oddity that no one is worried enough to bother measuring the actual supposed decline of the seventh wonder of the modern world. Fifteen years is a long time to overlook that. Many panicked press releases have gone under the bridge yet apparently AIMS (and all the others) just want to keep quoting the shrinking growth rates, but not keep track of them.

On top of that, Peter Ridd and Jennifer Marohasy have spotted a pretty major flaw in the methodology for that much quoted study that claims growth on the reef has slowed by 15% from 1990 to 2005. If that number is right, the reef will have ground down to a 30% decline by now [in growth rate]. Disaster, disaster. Worthy of a hundred press releases and a thousand grants. So either it just hasn’t occurred to AIMS et al to keep studying the reef they […]

Great Barrier Reef lives, misrepresents The Guardian and Expert who said corals were dead

Stone Island is the reef that put Peter Ridd’s career on the road to the high court. Last week Jennifer Marohasy released a mini documentary showing corals around Stone Island that weren’t supposed to be there. It was a bad look for Dr Tara Clark, the expert who had said the corals were gone.

This week Graham Readfearn hit back with “Scientists say rightwing think tank misrepresented her Great Barrier Reef study”. Apparently Marohasy must have used a right wing camera or something. (Those corals you saw are not really corals). If only Readfearn had not used a left wing keyboard, where the only truths it could tell were projections of his own flaws onto everything else.

Dr Clark apparently now denies she said the corals were all dead. Saying “We never claimed that there were no Acropora corals present in 2012.” Poor Guardian readers, as usual, get spoon-fed thin slices of technicalities and weasel words, never the whole truth.

This picture was taken with Jen Marohasy’s drone, Skido, looking south east towards the edge of Pink Plate Reefon 26th August 2019.

Are you now or have you ever been an Acropora coral?

In reply Jennifer Marohasy just […]

According to Nature these corals do not exist

The aim was just to record what was there… don’t believe your lying eyes.

Fortunately, this science is not peer reviewed.

Coral reef totally recovers (for 400th time) and researchers surprised

If only coral researchers read skeptic blogs, they’d know that corals have been getting bleached and wrecked by cyclones for millions of years. They have adaptable genes, honed by 500 million years of natural selection, plus epigenetic tricks, and with safe zones to seed recovery. The Great Barrier Reef spans 2,000 kilometers and five degrees Celsius from 27 to 32°C and we’re still finding reefs we didn’t even know about. The pH swings on a daily basis, and fish do better when it does. One coral has adapted to ocean “acidification” in 6 months. Other fish remarkably adapted from salt to freshwater in just fifty years. As Peter Ridd says: Of all the ecosystems in the world, the reef is one that’s best at adapting to climate change.

So once again, corals have recovered — and yet the “experts” who wear their dogma covered glasses didn’t see it coming.
