Complaint about misleading Helen Caldicott article in “The Saturday Paper”

Guest Post by Geoff Russell. Geoff recently released the popular book “Greenjacked! The derailing of environmental action on climate change“.


Preamble Following a recent article by Helen Caldicott in The Saturday Paper I submitted the following complaint to The Australian Press Council. Unfortunately TSP isn’t a member of the Press Council. Nonetheless they were kind enough to review my complaint and informed me that op-ed articles are judged rather differently from news reports and that even if TSP were a member, they would take no action. Given the high number of factually incorrect claims by Caldicott, I asked for an example of a false or misleading claim that would warrant Press Council action. None was offered. Accuracy features strongly in the Press Council General Principles, but where nothing is inaccurate enough to warrant censure, then it hardly matters what they claim to give a damn about.

Background

Helen Caldicott is a well known ex-pat anti-nuclear activist. She recently (30/5) published an article in The Saturday Paper called “SA’s short-sighted view of uranium and nuclear options”. It’s some 1700 words long and a written in a gish-gallop debating style, packed full of technical jargon, sweeping and unsupported claims. (Editorial note: It was a similar performance by Dr Caldicott that turned George Monbiot’s opinion on nuclear around, as explained here and referenced in the blog post’s lead image above). It would have taken many thousands of words to respond to all of its claims, so rather than do that I wrote a 1300 word response which explains in lay language enough of the modern scientific picture of DNA damage and disease to explain why Caldicott’s three decades of predictions of nuclear catastrophe have failed dismally. I thought concentrating on explaining basic principles was preferable to a blow by blow rebutt al. That she is wrong matters less than understanding why.

Erik Jensen of The Saturday Paper rejected the piece saying they didn’t have space and suggested I submit a 100 word letter instead. I later found out that he had also rejected a response from Ben Heard who was named and subjected to an ill-informed hatchet job in the article. Ben subsequently gave up arguing with Erik who refused his reasonable requests for a proper response. Instead, Ben published a piece on his DecarboniseSA blog.

I decided instead to make a complaint to you, The Press Council, in the hope of getting an apology from The Saturday Paper both for publishing an article so clearly in violation of the Press Council General Principles; an article replete with misinformation and the omission of key facts. I also want TSP to publish a suitable response to Caldicott’s article; something of similar length.

I’d be happy, if required, to send the Press Council a copy of the original piece I sent TSP; but what follows is a more clinical blow by blow analysis of Caldicott’s misinformation and why it breaches Press Council Principles.

About the article itself

As I said above, dealing with a 1700 word article with sometimes multiple mistakes per sentence is a big job, so I’ll restrict myself to the most important examples which I believe violate the Press Council’s General Principles. Indented paragraphs are quotes from Caldicott’s article.

  • [MISLEADING: solar farms use far more concrete] Construction of the huge reactor complex adds substantially to global warming as it is largely made of concrete – a CO2-intensive product.

This is misleading because it omits a key fact, namely that nuclear power plants require considerably less concrete (and steel) per unit of energy than either a solar or wind farm.

For example comparing materials per megawatt hour for the Spanish Andasol I solar thermal farm in comparison to a Westinghouse AP1000 nuclear reactor shows the solar farm uses 15 times more concrete (and 75 times more steel, not to mention 2,530 times more land). And this is a generous comparison, because the reactor will last twice as long, so you’ll be building the solar farm twice.

  • [MISLEADING: irrelevant] …[a] 1000-megawatt reactor requires one million gallons of water a minute, for cooling.

Again misleading. Most nuclear reactors use water for cooling, just like all thermal power stations, whether they be coal, gas, biomass or solar thermal. Any power plant which heats water to drive a turbine is most efficiently designed using lots of water for cooling. But it isn’t strictly necessary, it’s just more efficient than air cooling. Typically, many nuclear plants are on the coast precisely to make use of the water because water cooling provides efficiency gains. You may not have this flexibility with coal or solar because the former need to be near mines and the latter need to be on cheap land, which isn’t normally coastal. The amount of water required has nothing to do with whether a plant is nuclear but on its thermal efficiency and the ambient temperature of the water. Continue reading

Willacy’s Fukushima

Guest Post by Geoff Russell. Geoff is a computer programmer, vegan, environmentalist, and more generally, a ‘by-the-numbers’ polymath. For a list of all of his posts on BNC, click here. He also has collections here and here.

The following article was sent to ABC’s “Drum” website about a month ago. They rejected it. I have asked why, but they refuse to give a reason. I would have thought that when a journalist so publicly associated with the ABC as Mark Willacy, makes serious factual errors in a book, that the ABC would publish a reasoned critique. Apparently not. 

ABC journalist Mark Willacy recently launched a book: “Fukushima: Japan’s tsunami and the inside story of the nuclear meltdowns”. The ABC is giving the book plenty of exposure and gave Willacy time off to write it.

Back in March this year I wrote an article on poll results exposing deep nuclear ignorance in Australia. Only 10 percent of Australians understood clearly that a nuclear explosion was impossible in a nuclear reactor. The other 90 percent occupied various positions along a spectrum between certainty of the facts and being equally certain that the impossible was possible.

Willacy doesn’t just believe that the impossible is possible, but that it’s already happened. His book reveals similar knowledge deficits not only in the Japanese public, but in many of those who oversaw Japan’s Fukushima meltdown response, including nuclear industry workers.

Willacy states clearly (p.128) that the Chernobyl reactor underwent a nuclear explosion in 1986. Not true or even possible. Power reactor fuel is simply wrong stuff. It’s as different from bomb material as potting soil is from gun powder. And even if you loaded a reactor with bomb grade enriched uranium, there’s no detonation mechanism. Designing and building the latter is one the hardest design jobs in building a nuclear bomb.

Confusion about categories of explosions may seem a small thing, but we’ll see that it extends to a more general ignorance about the nature and scale of radiation risks.

Explosion types, no small matter

Here’s a couple of pictures illustrating the difference between what Willacy claimed happened at Chernobyl and what actually happened … a steam explosion. The image on the left is of a nuclear explosion (the World War II Hiroshima bombing) which flattened about 700 hectares of buildings and killed about 60,000 people with its blast heat and pressure waves. An additional similar number died in the following weeks from various injuries, including radiation received from the blast. The image on the right is the aftermath of the Chernobyl explosion … a steam explosion which blew the top off the reactor, killed two workers and mangled a building. But, as you can see, it didn’t even have enough power to knock over a tower a few metres away from the blast.

Hiroshima: nuclear explosion

Hiroshima: nuclear explosion

Chernobyl: steam explosion

Chernobyl: steam explosion

The above two images are at very different scales, but the difference is clear…

A steam explosion, together with a larger radiation release could definitely have happened at Fukushima if workers at the plant hadn’t succeeded in releasing steam (including radioactive material) from the reactors. This was definitely worth avoiding, but it could never have been a nuclear explosion. Nor could it have possibly killed any workers in the anti-seismic command bunker hundreds of meters away. The worker death fears described by Willacy were clearly very real to them, but they weren’t at any risk of death other than when out of the bunker and close to the reactor. As at Chernobyl and at the recent fertiliser explosion at West near Waco in the US, it’s usually the firefighters taking the big risks. The West explosion left a 93-foot crater and killed 14 people, mostly the firies … this was a much, much bigger bang than Chernobyl. The 1947 Texas fertiliser explosion was a very much bigger bang again, it levelled 1,000 buildings, killed 581 people and even knocked a couple of planes out of the sky.

CO2 is a trace gas, but what does that mean?

Carbon dioxide, methane, nitrous oxide and most other long-lived greenhouse gases (i.e., barring short-lived water vapour), are considered ‘trace gases’ because their concentration in the atmosphere is so low. For instance, at a current level of 389 parts per million, CO2 represents just 0.0389% of the air, by volume. Tiny isn’t it? How could such a small amount of gas possibly be important?

This issue is often raised by media commentators like Alan Jones, Howard Sattler, Gary Hardgrave and others, when arguing that fossil fuel emissions are irrelevant for climate change. For instance, check out the Media Watch ABC TV story (11 minute video and transcript) called “Balancing a hot debate“.

I’ve seen lots of analogies drawn, in an attempt to explain the importance of trace greenhouse gases. One common one is to point out that a tiny amount of cynanide, if ingested, will kill you. Sometimes a little of a substance can have a big impact.  But actually, there’s a better way to get people to understand, and that’s to follow one of the guiding principles of this blog: “Show me the numbers!“.

In response to a recent post by John Cook on George Pell, religion and climate change, commenter Glenn Tamblyn pointed out an interesting fact: Every cubic metre of air contains roughly 10,000,000,000,000,000,000,000 molecules of CO2. In scientific notation, this is 1022 — a rather large number.

Clearing up the climate debate

The Conversation is a recently established website set up to provide an independent source of information, analysis and commentary from the Australian university and research sector. Over the last few weeks, a group of climate scientists and academics from other relevant disciplines, have been running a series at The Conversation on ‘climate change scepticism’. I’ve been involved with a group, lead by Steve Lewandowsky from UWA and Megan Clement from The Conversation, that initiated and organised the concept for this series, and the result has been some terrific articles published by folks like Karl Braganza (BoM), James Risbey (CSIRO), Ian Enting (Univ Melb) and many others. You can browse the full listing of 13 articles here.

I was a co-signatory of the lead article, Climate change is real: an open letter from the scientific community, and also the concluding piece. I reproduce the latter, below (for the original posting at The Conversation, click here).

The false, the confused and the mendacious: how the media gets it wrong on climate change

The Conversation wraps up Clearing up the Climate Debate with a statement from our authors: the debate is over. Let’s get on with it.

Over the past two weeks The Conservation has highlighted the consensus of experts that climate change caused by humans is both real and poses a serious risk for the future.

We have also revealed the deep flaws in the conduct of so-called climate “sceptics” who largely operate outside the scientific context.

But to what extent is the “science settled”? Is there any possibility that the experts are wrong and the deniers are right?

Certainty in science

If you ask a scientist whether something is “settled” beyond any doubt, they will almost always reply “no”.

Nothing is 100% certain in science.

So how certain is climate science? Is there a 50% chance that the experts are wrong and that the climate within our lifetimes will be just fine? Or is there a 10% chance that the experts are wrong? Or 1%, or only 0.0001%?

The answer to these questions is vital because if the experts are right, then we must act to avert a major risk.

Climate Change – it’s complicated, but it’s real

I was recently invited to provide a response to an opinion article on climate change that was offered to “The Punch” website. The lead article can be read here: It’s just too hard to understand climate change. My response, reproduced below (original here), should be read with this context in mind.

It seems that many of the commenters on The Punch website thought I was being patronising or pontificating. Maybe I was, but how else to answer such a “it’s all too hard” complaint? As one of the others commenters noted: “If wishes were horses, beggars would ride”, i.e. just wanting for simple answers and consistent outcomes won’t make them so. Anyway, see what you think…

————————

Dylan Malloch laments that understanding climate change is difficult, with the forecasts sometimes appearing to be contradictory or having a bit both ways, and therefore seeming all rather confusing! It’s easy to sympathise with him. Unfortunately, this is the nature of science.

Let’s consider another example. Newton’s laws of physics work just fine for the everyday world, but if we tried to use them in the timing system of our global positioning satellites, the resulting drift error would be about 10 kilometres every day.

So, the engineers at GPS mission control need to use Einstein’s relativistic theories to make sure your iPhone tells you precisely where you are, whenever you want to know. Similarly, neither Newton’s or Einstein’s equations allow scientists to properly predict the subatomic interactions within the electronics of satellites or iPhones. For that, you need to reference the weird world of quantum mechanics.

Each of these model systems – Newtonian, Einsteinian and Quantum physics – produce some contradictory predictions, and gaps in understanding remain. The theories have not yet been unified, for instance, to the lament of Einstein and his successors.

Yet the vast majority of us – the average Joe and Josephine Public –  are not confused or worried about GPS and iPhones, for the simple matter that we don’t try too hard to understand how they work. After all, it’s plain enough to our eyes, immediately and incontrovertibly, that they do! So we just accept it, like we do for most forms of technology.

Climate science is now treated rather differently, however. This is because although the stochastic and chaotic systems involved are, in their own way, just as complex as relativity and quantum theory, many people just don’t want to take the underpinning science and evidence for granted.
