Australia's Climate Change Conspiracy Theorists Get Angry Over Radio Interview That Never Happened

In the space of six days, Rupert Murdoch's The Australian newspaper has published five news stories and an opinion piece attacking the credibility of the Australian government's weather and climate agency, the Bureau of Meteorology.

I've covered the guts of the early stories over on my Planet Oz blog for The Guardian.

But the core of it is that Dr Jennifer Marohasy, a former Institute of Public Affairs free market think tankerer, is claiming that the BoM has, in her words, “corrupted the official temperature record so it more closely accords with the theory of anthropogenic global warming”.

Marohasy is a researcher at Central Queensland University with her work funded by another climate change “sceptic”.

She has has not published her analysis in any journal, yet The Australian's Graham Lloyd has deemed the claims of a climate science sceptic on blogs worthy enough of five news pieces.

I just want to deal with his latest story here, that comments on the BoM's process of transparency.  The story includes this bit:

The bureau has been under fire for not making publicly available the methodology used for homogenisation. Michael Asten from the School of Earth Atmosphere and Environment at Monash University said confidence in BOM’s data would increase “if and when BOM publishes or supplies its homogenisation algorithms, a step which would be quite consistent with existing ­requirements of the better peer-reviewed journals.’’ BOM said its methods had been published in peer-reviewed scientific journals but did not say where or in what form.

This claim is - oh what's the word - bolloxxs (sorry kids).

Richard Tol's Attack On 97 Percent Climate Change Consensus Study Has 'Critical Errors'

Professor Richard Tol

One of the most consistent of all the attacks from climate science sceptics and deniers is the one which tries to convince the public that expert scientists are divided on the causes of climate change.

Those attacks have come from ideologically motivated think tanks and the fossil fuel industry, often working together. Only last week, the Wall Street Journal published a polemic to try and mislead the public that a consensus does not exist.

In 1998, the American Petroleum Institute was developing a campaign with the explicit aim of convincing the public that “uncertainties” existed in the science of climate change and its causes.

In 2002, Republican pollster Frank Luntz wrote that: “Should the public come to believe that the scientific issues are settled, their views about global warming will change accordingly.”

Several studies have surveyed the views of climate science experts or the scientific literature and have come to the same conclusions — the number of studies and the number of scientists who reject the fact that humans are causing climate change remains vanishingly small.

The latest and most high profile study to survey the scientific literature was led by John Cook, of the University of Queensland’s Global Change Institute and founder of the Skeptical Science website, and published in the journal Environmental Research Letters in May 2013.

Cook et al analysed close to 12,000 global warming studies from 1991 to 2011 to see how many accepted or rejected the fact that human activities are causing climate change. The researchers also asked scientists themselves to look at their own papers and confirm whether they endorsed the scientific consensus.

The central finding, reported widely and even Tweeted by Barack Obama’s campaign team, was that 97 percent of the scientific papers on climate change found that humans were causing it.

Since that study was published, Professor Richard Tol, an economist from the University of Sussex, has been planning to attack Cook’s paper.

The Campaigns That Tried To Break The Climate Science Consensus

So just in case anyone wasn’t sure, a major study of almost 12,000 scientific papers on global warming between 1991 and 2011 finds less than one per cent disagree that humans are the main cause.

Published in the journal Environmental Research Letters, the study led by John Cook, the Australia-based founder of Skeptical Science, confirms the debate about the causes of global warming had all but vanished in the scientific literature by the early 1990s. Almost all the research says it’s mostly caused by humans.

For any followers of climate science in journals (the place where it actually matters) the finding wasn’t really news at all.

Yet survey after survey finds the public still thinks scientists are arguing over the causes of global warming and the media continues to attempt to resuscitate long-dead ideas.

Does it matter that people have a clear understanding of the main thrust of the science? A 2012 study in the journal Nature Climate Change found that people were more likely to accept human-caused global warming if they were informed that scientists were in broad agreement (which we know they are).

For decades, fossil fuel-funded groups, free market think tanks (some of which also qualify as fossil fuel funded groups) and the fossil fuel industry itself have known the importance of the public’s understanding of the state of climate science. A public that understands the state of the science is more likely to want something done about climate change. Doing something, means using a lot less fossil fuel.

But who wanted to tell the public that a consensus didn’t exist? Here are just some of the campaigns run over the years showing how breaking the consensus in the eyes of the public was a key strategy.

The Science of Debiasing: The New “Debunking Handbook” Is a Treasure Trove For Defenders of Reason

For quite some time here at DeSmogBlog, I’ve been writing about the growing science of irrationality—in other words, our ever-better scientific understanding of why people reject clearly correct information. I believe we can’t possibly get to a better place, in debates over issues like global warming, until we understand why getting facts across turns out to be so difficult.

A large amount of psychological science has now been published on this matter—but boiling it all down into a practical, usable guide for someone who wants to communicate in a scientifically-informed way? Not so much.

Not until now.

I simply cannot believe that John Cook of Skeptical Science and psychologist Stephan Lewandowsky managed, in just 8 pages, to create something as magnificent as their new Debunking Handbook. It is packed not only with wonderful graphics, but also with a clear explanation of why many attempts to defeat misinformation fail, and what steps must be taken to do a better job.

The core issue, of course, is one that I’ve written much about—too many scientists assume that that facts win out on their own, but that isn’t actually true. If you base your communication strategy on this misconception, you will fail very badly.

Instead, Cook and Lewandowky explain that there are a variety of “backfires” that can be triggered by uninformed communication styles. Stating a myth before debunking can actually reinforce it. Debunking a myth with an overload of information can also backfire. And attacking a worldview can backfire most of all.

So what do you do? You should read their guide, but basically it boils down to several principles:
