A 2010 survey of 1,372 climate scientists by the National Academy of Sciences found that more than 97 percent of those publishing in the field believed humans were the main cause of global warming over the past century.Flashback: Global Warming: A 98% Consensus Of Nothing - Forbes
In the “survey” to which Huntsman alluded, scientists were invited to participate in a two-question online survey. Despite what Huntsman said, not even 100 climate scientists chose to participate. The two questions were simple: 1. Have global temperatures risen during the past 200 years? and 2. Are humans a significant contributing factor to this?Global Warming: A '98% Consensus Of Nothing': 'Only shameless activists or statistically ignorant claim that survey of 77 anonymous scientists' is proof of 98% 'consensus' | Climate Depot
Forgetting for the moment that only shameless activists or the most statistically and scientifically ignorant of persons would claim that a survey sample of only 77 scientists volunteering to participate in a survey is indicative of what the entire climate science community believes, the questions and answers themselves tell us nothing.
'Regarding the 2nd question, is human activity a significant contributing factor? Notice how the question did not say 'sole factor,' 'majority factor,' or even 'primary contributing factor.' Rather, the term is merely 'significant contributing factor.' More precisely, if human activity is not a 'significant' contributing factor then it must be an 'insignificant' contributing factor. What is threshold between 'significant' and 'insignificant'? 5% ? 10%?'
