Another kick-ass article on The Conversation, providing some insights into the scientific process and the place that pseudo-skepticism takes in (or rather outside of) that process.
In science, to actually contribute at the forefront of a field one has to earn credibility, not demand it. Being taken seriously is a privilege, not a right.
In science, this privilege is earned by not only following conventional norms of honesty and transparency but by supporting one’s opinions with evidence and reasoned argument in the peer-reviewed literature.
This is what makes science self-correcting. If arguments turn out to be wrong, in time they are caught and corrected by other scientists. It is virtually impossible to publish long-refuted nonsense in good peer-reviewed journals.
an overwhelming scientific consensus does not imply the absence of contrarian voices even within the scientific community.
Over time, those contrarian voices simply fade away because no one takes them seriously, despite their shouts of “censorship” and accusations of bias.
This is not to say that a scientific consensus is never overturned.
There are well-known examples such as the Helicobacter pylori discovery in medicine, and continental drift in geology. But in both cases the arguments were won and lost in the peer-reviewed literature, not by contrarians sitting on the side-lines writing opinion pieces about how they were being oppressed.
A ‘change in paradigm’ occurs when the evidence for the prevailing theory is shown to be weak, and the evidence for a competing theory is getting stronger. That is the opposite of what has been happening in climate science over the past 150 years: The evidence of human influence on climate has been steadily accumulating from the time that it was first postulated as a prediction. Arguments against it have been shown to be either wrong or irrelevant for the big picture.
Even more so, the prevailing paradigm (that us tiny humans can’t possibly compete with the great forces of nature in affecting the earth’ climate) has been gradually overturned by the evidence which pointed out that yes, we can.
Back to The Conversation. Read and shudder:
One self-proclaimed “rocket scientist” who has published junk science in the opinion pages of The Australian has been quoted on aNew Zealandwebsite as saying:
“To win the political aspect of the climate debate, we have to lower the western climate establishment’s credibility with the lay person. And this paper [an accompanying picture book of thermometers] shows how you do it. It simply assembles the most easily understood points that show they are not to be entirely trusted, with lots of pictures and a minimum of text and details. It omits lots of relevant facts and is excruciatingly economical with words simply because the lay person has a very short attention span for climate arguments. The strategy of the paper is to undermine the credibility of the establishment climate scientists. That’s all. There is nothing special science-wise.”
Are these the people one should entrust with the welfare of future generations?
The tried and tested strategy of sowing doubt in the minds of the public seems to be supplemented by a strategy of lowering the scientists’ credibility. The latter strategy seems to be at least as successful as the former, if recent events are any guide.
PS: I’m well aware that the bulk of public skepticism is not based on a well orchestrated campaign, but stems more from individual reasons (which I’ve discussed in a previous post). That does however not negate the fact that certain lines of reasoning are repeatedly used in the public debate.
Another necessary element of denial is conspiratorial thinking. Any denier sooner or later, whether an academic or not, must resort to a global conspiracy theory to negate the overwhelming evidence arrayed against them.
Just imagine the devastating rebuttal of climate change that Bob Carter could submit for peer-review if he wasn’t being oppressed by the Archbishop of Canterbury and Prince Charles.
Time to close the phony debate on climate science
At a time when the oceans are accumulating heat at the rate of five Hiroshima bombs per second, are conspiracy theorists the people whom a nation should entrust with the future of our children?
The so-called “debate” on climate change has been over for decades in the peer-reviewed literature. It is time to accept the scientific consensus and move on, and to stop giving air-time to the cranks.
It is time for accountability.

Part Three: Speaking science to climate policy.
PS: Even though I chose not to use the word “denier” to describe those who don’t accept mainstream science, I did not change it from the original text as quoted. However, I do not intend to host a discussion here on the arguments pro and con of using this or the other label.
