I looked up the 97 percent figure and it seems to have come from cook and etc. Here is what wiki has to say about it:
"Cook et al. examined 11,944 abstracts from the peer-reviewed scientific literature from 1991–2011 that matched the topics 'global climate change' or 'global warming'. They found that, while 66.4% of them expressed no position on anthropogenic global warming (AGW), of those that did, 97.1% endorsed the consensus position that humans are contributing to global warming. "
A few things jumped out right away, even to someone without fancy degrees:
1. They reviews abstracts, not papers themselves.
2. They counted papers, not scientists.
3. Most of the papers (two thirds) said nothing about agw - what a surprise.
4. Of the minority that did, 97 of them, or 30 percent of all the papers reviewed, said that humans contributed to agw - a position I agree as well.
That position is vastly different from the authors representation that 97 percent of the climate scientists agreed that humans caused most of the warming.
That kind of representation, based on the survey results, is a fraud.
