Australia: Prof Peter Ridd: the Great Barrier Reef recovers, our science institutions are failing us, science needs to be checked

Who is Peter Ridd? Some context first:

>>>>>>>>>>>>>>>>>>>>>>

Background:

When marine scientist Peter Ridd suspected something was wrong with photographs being used to highlight the rapid decline of the Great Barrier Reef, he did what good scientists are supposed to do: he sent a team to check the facts.

After attempting to blow the whistle on what he found — healthy corals — Professor Ridd was censured by James Cook University and threatened with the sack. After a formal investigation, Professor Ridd — a renowned campaigner for quality assurance over coral research from JCU’s Marine Geophysics Laboratory — was found guilty of "failing to act in a collegial way and in the academic spirit of the institution".

His crime was to encourage questioning of two of the nation’s leading reef institutions, the Centre of Excellence for Coral Studies and the Great Barrier Reef Marine Park Authority, on whether they knew that photographs they had published and claimed to show long-term collapse of reef health could be misleading and wrong.

The coral reef recovers.

Peter Ridd: Coral Reefs recover — "the scientists make hay when it dies in a spectacular way but they are quiet when it recovers."

On symbionts — "There is a large variety of symbionts and some allow coral to grow faster but are more sensitive to bleaching."

All the corals on the Great Barrier Reef live and grow much faster in Papua New Guinea, Indonesia and Thailand where the water is much hotter than it is on the reef and the corals just juggle these symbionts.  

Corals have a little thermometer built in them, when you take a core of them from many years ago we know what the temperature of the water was back when Captain Cook sailed up the coast, it was actually about the same temperature then. It was colder 100 years ago, but it has recovered from that. The temperatures on the reef are not even significantly warmer than average on a hundred year timescale.

Corals that bleach in one year will be less susceptible to bleaching in following years.

On the failure of modern science:

Peter Ridd: We can no longer rely on our science institutions. This is a very sad thing.

We are like a ship upon the ocean when our science fails and we need to do something about it. … This science is almost never checked.

Alan Jones: All these things [bleaching, crown of thorns] have been around for millennia, I love this line, as you write "long before scientists got hold of any scuba gear."

Peter Ridd: These things only became a problem when scientists pop up on the scene.

Scientists are trying to close down, or affect adversely the sugar cane, the cattle, and the coal industry, and they are also telling the world the reef is dead which affects the tourist industry in Queensland.

Like a bushfire… It [bleaching] looks terrible when it happens but it grows back.

On the future:

Peter Ridd: There needs to be a properly funded group of scientists who sole job is to find fault in the science with which we are basing expensive public policy decisions ….

Warmists take note: Scientists are stunned by corals as big as cars and thriving marine life at Bikini Atoll site where 23 atomic bombs were dropped

Corals and much else are not in danger anywhere on this  evidence.  It is also evidence that the harm from radiation has been much exaggerated

Bikini Atoll, the former paradise island used by the US to carry out 23 nuclear weapons tests 70 years ago, is now teeming with life, scientists have found.

The Pacific Ocean island has blooming populations of plants and animal life, filled with fish such as snapper, sharks and tuna while boasting corals as big as cars.

Crabs the size of hubcaps are said to be feasting on coconuts filled with radioactive groundwater as part of an ecosystem described by experts as 'remarkably resilient'.

Scientists are now sequencing the DNA of the Bikini Atoll coral to better understand how they are able to survive.

The study may help researchers better understand how certain DNA can combat genetic diseases, such as cancer.

During the Cold War, the US detonated 23 nuclear bombs at Bikini Atoll, including a device in 1954 that was 1,100-times more powerful than the Hiroshima atom bomb.

The blasts, detonated in the years between 1946 and 1954, exposed corals and other species to persistent, high levels of radioactivity.

At the time of the tests, residents of the islands were moved to other locations, and the site has remained uninhabited  beyond a handful of caretakers since.

A 2012 report to the United Nations stated that there was 'near-irreversible environmental contamination' to the former nuclear site.

But scientists have found that populations of coral, crabs, fish and sharks are thriving at Bikini Atoll.

A researcher told the Guardian that fish populations are thriving because they have been left alone - 'in a strange way they are protected by the history of this place'.

The findings, led by scientists at Stanford University in northern California, featured in an episode of Big Pacific aired on June 28, a natural history TV series on PBS.

The five-part series, which looked at strange wildlife populations in the Pacific Ocean, did not air in the UK but will be available to buy on DVD later this year.

The study focused on reports of mutant sharks that are missing their second dorsal fin around a submerged hydrogen bomb crater near the island.

Professor Steve Palumbi, a marine scientist at Stanford whose team have been studying the effects of radiation poisoning on marine life, said the bizarre ecosystem is 'remarkably resilient'.

He said that, to the naked eye, the crabs, fish and corals around Bikini Atoll look perfectly normal, and some of the coral has been around for decades.

During the Cold War, the US detonated 23 nuclear bombs at Bikini Atoll, including a device in 1954 that was 1,100-times more powerful than the Hiroshima atom bomb.

The blasts, detonated in the years between 1946 and 1954, exposed corals and other species to persistent, high levels of radioactivity.

The researchers discovered plentiful schools of fish at a lagoon near the Micronesian island, located halfway between Hawaii and Australia.

Professor Palumbi told the Guardian that fish populations are thriving because they have been left alone - 'in a strange way they are protected by the history of this place'.

'It is a remarkable environment, quite odd,' he said.

The fish spawn around the island's waters using an abundant population of coral that seems unaffected by the deadly radiation at the site.

Professor Palumbi and his team are now sequencing the DNA of the Bikini Atoll coral to better understand how they are able to survive.

The study may help to develop research into genetic diseases, such as cancer, in humans.

'The terrible history of is an ironic setting for research that might help people live longer,' Professor Palumbi said.

'By understanding how corals could have recolonised the radiation-filled bomb craters, maybe we can discover something new about keeping DNA intact.'

Although local wildlife appears to be flourishing, the Bikini Atoll site is still considered dangerous to humans.

A 2012 report to the United Nations stated that there was 'near-irreversible environmental contamination'.

'This is the most destructive thing we have ever done to the ocean, dropping 23 atomic bombs on it, yet the ocean is really striving to come back to life,' said Professor Palumbi.

'The fact there is life there and the life there is trying to come back from the most violent thing we've ever done to it is pretty hopeful.'
