From climate change to peak oil and food insecurity, our societies are confronted with many serious challenges that, if left unresolved, will threaten the well-being of present and future generations, and the natural world. This website is dedicated to discussion of those challenges and potential solutions based on scientific evidence and scholarly analysis.

Our goal is to provide a platform for re-examining some of the assumptions we make about our technological, social and economic systems. The posts on this site are generally written by domain experts, specialists and scholars with an interest in these problems and we hope they will generate informed and constructive debate. We will archive seminal papers and posts for future reference.

Putting the pause to a blind expert test

Posted on 16 September 2015 by Stephan Lewandowsky

The paper is authored by Stephan Lewandowsky, James Risbey, and Naomi Oreskes. It is open access and can be found here.

Announcing the Uncertainty Handbook

Posted on 6 July 2015 by Adam Corner

Have you ever struggled with the communication of climate change uncertainties? Are you frustrated by climate sceptics using uncertainty - inherent in any area of complex science - as a justification for delaying policy responses? Then the new ‘Uncertainty Handbook’ - a collaboration between the University of Bristol and the Climate Outreach & Information Network (COIN) - is for you. The handbook was authored by Dr. Adam Corner (COIN), Professor Stephan Lewandowsky (University of Bristol), Dr Mary Phillips (University of Bristol) and Olga Roberts (COIN)All are experts in their fields and have expertise relating to the role of uncertainty in climate change or how best to communicate it.

Voices from the climate community on "seepage"

Posted on 14 May 2015 by Stephan Lewandowsky

Our recent article “Seepage: Climate change denial and its effect on the scientific community” in Global Environmental Change, authored by me and Naomi Oreskes, James S. Risbey, Ben R. Newell, and Michael Smithson, has attracted a bit of attention over the last few days. I sample a few comments here and reply to a lengthy post by Richard BettsHead of the Climate Impacts strategic area at the UK Met Office, that critiqued our paper.

The robust relationship between conspiracist cognition and rejection of (climate) science

Posted on 27 March 2015 by Stephan Lewandowsky

There are two articles in Psychological Science that appeared online today: The first article by Ruth Dixon and Jonathan Jones presents an alternative analysis of two papers that I published with colleagues in 2013 on the role of conspiracist ideation in the rejection of science. The second article is a rejoinder to Dixon and Jones and is authored by me together with Gilles Gignac and Klaus Oberauer.

Cash for comments vs. public funding of science

Posted on 6 March 2015 by Stephan Lewandowsky

The revelation of the “cash for comments” that may have turned Dr. Soon into a mercury expert has highlighted the potentially pernicious role of funding from vested interests in science. (Non-Australian readers who are not familiar with the “cash for comments” saga will find it explained on Wikipedia).

Cash for comments: The public has a right to know

Posted on 5 March 2015 by Stephan Lewandowsky

“In 1954 the tobacco industry paid to publish the ‘Frank Statement to Cigarette Smokers’ in hundreds of U.S. newspapers. It stated that the public’s health was the industry’s concern above all others and promised a variety of good-faith changes. What followed were decades of deceit and actions that cost millions of lives”—so reads the opening paragraph of a recent peer-reviewed paper on the history of how Big Tobacco “played dirty” by injecting lavish amounts of money into a public-relations campaign aimed at undermining the scientific evidence linking tobacco smoke to adverse health impacts.

How to build support for climate policies?

Posted on 10 February 2015 by Mark Hurlstone & Stephan Lewandowsky

Our paper, entitled “The effect of framing and normative messages in building support for climate policies”, was recently published in the open-access journal PLoS ONE. The paper reports a media analysis of the framing of Australia’s carbon pricing scheme along with two studies exploring approaches to building public support for reducing emissions. The abstract for the paper reads as follows:

The EU Science Advisor: Greenpeace and Climate Denial

Posted on 13 November 2014 by Stephan Lewandowsky

After being rumored for some time, the E.U. has now abolished the post of Chief Scientific Adviser. I have been following this from a distance, and although there may be some nuances that I am unaware of, my first reaction is that I am in agreement with Mark Lynas, namely that

Naomi Klein in Oxford

Posted on 12 October 2014 by Stephan Lewandowsky

Naomi Klein spoke in Oxford a few days ago on invitation of COIN, the Climate Outreach Information Network in the UK. Her talk was in the Sheldonian Theatre, the official ceremonial hall of the University of Oxford—a ceremonial building indeed that added much to the enjoyment of the evening. Naomi drew a large crowd—of more than 800, so I have been told—and the event was very interesting indeed.

The Australian's Disappearing Comissar

Posted on 3 October 2014 by Stephan Lewandowsky

Update 3 October 11:33: Apparently there are two versions of the AP story, the earlier of which contained no mention of the Australian heatwave. This information was revealed by Seth Borenstein in a Twitter exchange which is recorded here. If The Australian relied on the earlier version, they would not have removed anything, and the remainder of this post is therefore irrelevant to their reporting in this instance. We now look forward to The Australian updating their AP report to reflect the elements that are of such obvious importance to Australia.

Putting a price on carbon: Why not a carbon tax?

In Australia there has never really been a debate about the merits of particular policy instruments available to governments – price-based or quantity-based ones – to mitigate the effects of climate change.

"Libertarian ideology is the natural enemy of science" Always?

Posted on 30 August 2014 by Stephan Lewandowsky

The Guardian carried an interesting and incisive piece yesterday under the headline “Libertarian ideology is the natural enemy of science.” From gun control to health care to climate change, there are indeed many arenas in which scientific evidence clashes with libertarian (and conservative) worldviews: To illustrate, even though the data show that if you are a victim of an assault, you are between 4 and 5 times more likely to be fatally shot if you had a gun available than if you didn’t have a gun, this evidence is generally dismissed by American libertarians and conservatives. They also dismiss the fact that after Australia introduced stringent gun control in 1996, accelerated declines in firearm deaths were observed.

Well-estimated global warming by climate models

Posted on 20 July 2014 by Stephan Lewandowsky

Has global warming “stopped”? Do models “over-predict” warming? There has been much recent talk in the media about those two questions. The answer to the first question is a fairly clear “no.” Global warming continues unabated.

Recursive Fury goes recurrent

Posted on 21 March 2014 by Stephan Lewandowsky

Some 18 months ago I published a paper with colleagues Oberauer and Gignac that reported a survey of visitors to climate blogs which established a small, but significant, association between the endorsement of conspiracy theories and the rejection of several scientific propositions, including the fact that the earth is warming from greenhouse gases. The effects reported in that paper have since been replicated with a representative sample of Americans. No scholarly critique of either paper has been submitted for peer review to any journal to date.
