Moth at New Anthropocene has a good article on the “consensus debate” – I note some of you have seen it, but worth reprinting:
Every single time researchers go to the otherwise wasted effort of reviewing the standing position of climate research in relation to anthropogenic climate change (for, in what other field of science do scientists undertake such analyses?), we hear the same backlash from the committed sceptics.
In fact, looking at the dismissal charges of conservative columnists in relation to climate change, Elsasser and Dunlap (2013) found that attacking the scientific consensus was by far the favoured approach. This illustrates just how much such anti-scientific groups understand the scientific consensus hurts their position, if it is against them.
And it is against them.
Time and time again, I comment that these committed sceptics just don’t get what scientific consensus is. Without blinkers, when one reads such consensus research papers as the recent Cook et al (2013) they find that such an analysis is NOT the result of questionnaires sent to scientists. It is in fact asking, “what is the position drawn from the conclusions of the paper and are these conclusions pro-anthropogenic climate change or not?”
Scientific consensus here is weighed by the evidence presented within peer-reviewed literature and not merely the expert opinion of a few. This is why it hurts the committed sceptic so much and needs such venomous denigration. Donna Laframboise sounds silly when she says, “science isn’t done by consensus” when one looks at what real scientific consensus is.
Moreover, local gold hoarding conspiracy theorist, Jo Nova, presents just how little she gets science in her reply to Cook et al (2013) by referring to her beloved, Oregon Petition Project;
“You want authority? Skeptics can name 31,500 scientists who agree, including 9,000 PhDs, 45 NASA experts (including two astronauts who walked on the moon) and two Nobel Prize winners in physics.”
Righto – is that what’s supposed to challenge empirical evidence? A bunch of names of people – the vast majority of which, regardless of their other achievements, are without any relevant training or contributed any relevant analysis to the related fields of science – signing on the dotted line…?
The Oregon Petition Project is a one-sided vote. It is irrelevant.
Science isn’t done by consensus and the scientific consensus isn’t done by people. It is done through evidence. Hence the print in Cook’s infogram; 97% of climate papers stating a position on human-caused global warming AGREE global warming is happening – and we are the cause.
Nowhere do the positions of people come into it. It’s an argument made on evidence, not opinion.
Yet the climate sceptics attempt to denigrate it as opinion, whilst providing evidence that IS based purely on opinion!!
There’s consensus and then there’s consensus. The body of scientific evidence simply does not support the committed climate scepticism and the sceptics know this fact and do whatever they can to present a sideshow and misrepresent the body of scientific evidence because of this.
There is no debate over consensus because the definition of it is different for those who accept scientific evidence and those determined to remain “sceptical”.
