Crabs are just another victim of Wind turbines thanks to EMF pollution from undersea cables

Edible crab like the one used in the study. Jean-Pol Grandmont Wiki

It’s a Nightmare on Crab Street

Crabs are being drawn to high electromagnetic (EMF) fields around undersea cables and getting trapped there for hours, “mesmerized”.

They are not just immobilized, in lab tests it screws up their blood chemistry and circadian rhythm too.

Nature-lovers might wonder what other marine life is also being impacted? What if the magnetic fields are playing havoc with migrating fish and turtles too? It might be handy to find that out before we build bigger taller towers offshore with bigger stronger cables.

Where is the Green outcry, or the Save-the-crabs campaign? Perhaps some kinds of pollution are OK “for the greater good”?

These are not some esoteric rare crustaceans, by the way, but common dinner crabs — the ones food chains and fisheries depend on.

If these crabs were victims of coal plants the headlines would be a catastrophe.

Underwater power cables are ‘mesmerizing’ crabs around Scotland

In a new study, researchers found brown crabs ‘freeze’ when they come too close to the electromagnetic fields generated by these cables. This disturbing behavior may negatively affect the marine creature’s […]

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 […]

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 […]

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 […]

David Attenborough’s reputation was last seen falling off a cliff

 

Attenborough turned a natural phenomenon into an advert for the Climate-scare industry. As Benny Pieser at GWPF points out Falling Walruses were turned into the new posterboy of climate change, “It would be a sad legacy if he did not set the record straight.””

Here’s the brief synopsis in case you don’t feel like watching walrus horror flicks.

Though this old video that Polar Bear Expert Susan Crockford found is kinda novel — you can see scientists test theories and then throw them out.

Biologists in 1994 noticed walruses falling down a steep incline. They tried to figure it out. They scratch their heads. Admit they don’t know. They saw it happen three years in a row, and as many as 120 walruses met a flattening end.

The first theory was the animals were trying to escape severe storms, but the next year the weather was perfect. Walruses rolled and crashed again. So did that theory.

The second theory, was that perhaps the sights and sounds of humans were putting them out… but no — discussions with locals suggested not.

The third theory was that they were suicidal. But Dr Seagers, quaintly, doesn’t think we should put human thoughts […]

Peter Ridd: The Great Barrier Reef has about the same amount of coral as in 1985

The IPA team interview Peter Ridd. He explains that what’s happening on the Great Barrier Reef with coral bleaching is a normal cycle. He tells his story of being censured at James Cook university, but admits the state of free speech at universities in Australia is non-existent — even after his win. They discuss how we might reform science with audits (universities are almost a lost cause). We’ll probably never know how many scientists think similar thoughts to Peter Ridd. We know that they’ll need a $250,000 legal fund if they say so.

UPDATE: Importantly — Ridd says that the admin are still utterly convinced they are right. They have no remorse, no recognition of why they were wrong. Does this mean admin staff now decide what science is, not Profs? Apparently so. They hold the purse strings, not the Profs. Power follows the money. Indeed, JCU has no commitment to free speech; they’ve now removed the clause that ensured Ridd won. In their minds, their mistake was not in being draconian, but being careless with legal clauses. The Deep State tightens its stranglehold on science.

Peter Ridd: Of all the ecosystems in the world, the reef is one that’s […]

“Surprise” Climate change, 900ppm CO2, acidification is good news for squid

Squid, “surprise” are going to do well with climate change. (If only it was going to happen).

In the new post-CO2 world, corn and soy may become weeds, but squid may take over the oceans:

Squid will survive and may even flourish under even the worst-case ocean acidification scenarios, according to a new study published this week.

Dr Blake Spady, from the ARC Centre of Excellence for Coral Reef Studies (Coral CoE) at James Cook University (JCU), led the study. He said squid live on the edge of their environmental oxygen limitations due to their energy-taxing swimming technique. They were expected to fare badly with more carbon dioxide (CO2) in the water, which makes it more acidic.

No academic could have guessed that squid would have evolved ways to control their own blood pH:

“Their blood is highly sensitive to changes in acidity, so we expected that future ocean acidification would negatively affect their aerobic performance,” said Dr Spady.

Atmospheric CO2 concentrations have increased from 280 parts per million (ppm) before the industrial revolution to more than 400 ppm today. Scientists project atmospheric CO2 — and by extension CO2 in […]

Solar cycles to blame for jellyfish plagues (not coal fired plants)

Image Erin Silversmith

Three amazing things in this story. One that solar cycles might influence the oceans to such an extent that jellyfish plagues are cycling in tune with the sun. Second is that the sun might control food for jellyfish on Earth somehow but have no effect on clouds, temperature or our climate (join the dots that expert climate models don’t). Third is that (briefly) there was actual scientific debate published on the ABC (even if only a few Australians were exposed to it). No one called anyone names, and both sides got to speak (albeit on different channels). Put it in your diary.

A couple of weeks ago on the ABC jellyfish were booming and it was because of climate change:

Jellyfish are causing mayhem as pollution, climate change see numbers boom

RN By Hong Jiang and Sasha Fegan for Late Night Live

…the brainless, spineless, eyeless, bloodless creatures are booming in numbers — and causing mayhem around the world.

Some scientists think jellyfish numbers are increasing as the climate changes — the creatures reproduce well in warmer waters.

Last year, Nick Kilvert of the ABC saw it as a […]

Cloud forming bacteria?

File this under: “How little we know.”

The upper troposphere is apparently teeming with particles of bacteria and fungi, surprising researchers.* Proving that life is tenacious and that microbes can survive just about anywhere, a team at Georgia Institute of Technology have discovered that quite a bit of what we assumed was dust and sea-salt may be bacteria aloft. Some of the little critters made it as high as the upper troposphere which is 10km up (where commercial flights cruise). No one is quite sure if the microbes “live” up there, or were just visiting.

The study showed that viable bacterial cells represented, on average, around 20 percent of the total particles detected in the size range of 0.25 to 1 microns in diameter. By at least one order of magnitude, bacteria outnumbered fungi in the samples, and the researchers detected 17 different bacteria taxa – including some that are capable of metabolizing the carbon compounds that are ubiquitous in the atmosphere – such as oxalic acid.

The bacteria were probably tossed up there by wind and waves:

When the air masses studied originated over the ocean, the sampling found mostly marine bacteria. Air masses that originated over land had […]
