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 the oceans — [...]
