Duarte also has strong criticisms of the Cook paper's methods, but he also states
"I think the consensus of climate scientists regarding the reality of human-caused warming is both real and correct" . He says that the "climate science consensus" is between 78 to 84%, which is still very strong, and believes that the consensus is NOT a fraud. So basically Robson's own "authorities" believe in the general scientific consensus that Robson's vid (and TA) try to diminish. I wonder if Robson was ignorant of that, or whether he concealed it?
Chris, I would fully agree there is significant political spin on both sides. Nothing can be taken at face value and you need to look at what they are actually saying.
The biggest issue I see here is the spin and misdirection around the wording of "scientific consensus" and what the definition of that is. If you see statements that reference any sort of "scientific consensus" without defining it, my experience is that there is an effort to decieve going on.
Take the quotes you have posted above. "
I think the consensus of climate scientists regarding the reality of human-caused warming is both real and correct" This sentence meets the outcome of the studies as it does not minimise human caused warming. A 1% contribution due heat island effect from cities falls into that statement. It's not exactly what they want to promote though.
Then he goes on to say this:
"I have very little reason to doubt that the consensus is indeed correct" as the above definition of "consensus" is broad, then this is a nothing statement.
Then he says.
"Published papers that seek to test what caused the climate change over the last century and half, almost unanimously find that humans played a dominant role." This is not supported, and it does not link back to the definition of "consensus" he used previously, however because he has used it in the same context, a casual reader will assume that sentance is about consensus. It is a very incorrect statement as no paper looked at "testing a cause of climate change" few looked at opinions of scientists and references in papers, and none looked at Climate Change, only Global Warming.
Pretty much every study or paper I have seen on the topic either supports a "Consensus" as "man has contributed to global warming to some degree, no matter how small the contribution". Or, if they use a tighter definition of majority contribution (50% or more) then they have been very selective in thier sampling or responses to achieve it and therefore cannot use general statements about broad "consensus".
In the case of Cooks paper he got a whopping 2% on the tighter definition of 50%+. And thats after discarding the 7000 papers who had no position. It's also why they declined to publish that category in thier paper. It only came out after the results were found by others on a UQ database.
There are so many examples of deliberate misdirection around consensus, it really is alarming. If the studies truly showed what they a saying they did, there would be no reason to be misleading.
