97% of scientists support the theory [and it is a theory] of man-made climate change…due in the main to CO2.
Except that is bunk based on a lie as we pointed out in 2015…..
No expert on statistics but looking at this I would say the 97% claimed stat for scientific consensus on global warming is a crock….
‘We analyze the evolution of the scientific consensus on anthropogenic global warming (AGW) in the peer-reviewed scientific literature, examining 11 944 climate abstracts from 1991–2011 matching the topics ‘global climate change’ or ‘global warming’. We find that 66.4% of abstracts expressed no position on AGW, 32.6% endorsed AGW, 0.7% rejected AGW and 0.3% were uncertain about the cause of global warming. Among abstracts expressing a position on AGW, 97.1% endorsed the consensus position that humans are causing global warming.’
So hang on……66.4% expressed no position on the causes of global warming…
but……32.6% endorsed the alarmist position.
And the 97%?
The 97% is 97% of that 32.6%, or least of ‘those who expressed a position’, which definitely counts out the 66.4% who expressed no position and is even more definitely not 97% of ‘all scientists’…by my reading of that explanation.
So maybe around 33% of the literature openly supports the man-made climate change theory.
We also noted this from the Guardian way back in 2014….the need to promote that ‘consensus’ message…
An interesting sequence of events followed the publication of a scientific paper I co-authored in May last year. The paper found a 97% consensus that humans were causing global warming in relevant scientific papers. [Really?…see above]
So there is still much work to do. Several decades of casting doubt on the consensus has contributed to maintaining the consensus gap. This is why communication experts urge scientists to communicate the 97% consensus. This approach is based on a growing body of evidence underscoring the important role of perceived consensus and the necessity of consensus messaging.
Which is why the Guardian leads its climate change articles with this lie even now….
And hilariously the Guardian had this piece yesterday from the person who invented the 97% figure…
You couldn’t make it up…oh, yes, you can and the Guardian does.
