From the Hockey Schtick:
The graphic [directly above] comes via our friends at skepticalscience, assuring us that while 97% of “climate scientists think that global warming is ‘significantly’ due to human activity,” a shocking 72% of news coverage does not reflect this “consensus” and similarly 74% of the public are not convinced.
However, close examination of the source of the claimed 97% consensus reveals that it comes from a non-peer reviewed article describing an online poll in which a total of only 79 climate scientists chose to participate. Of the 79 self-selected climate scientists, 76 agreed with the notion of AGW. Thus, we find climate scientists once again using dubious statistical techniques to deceive the public that there is a 97% scientific consensus on man-made global warming; fortunately they clearly aren’t buying it.
From the EOS article
Results show that overall, 90% of participants answered “risen” to question 1 and 82% answered yes to question 2. In general, as the level of active research and specialization in climate science increases, so does agreement with the two primary questions (Figure 1). In our survey, the most specialized and knowledgeable respondents (with regard to climate change) are those who listed climate science as their area of expertise and whoalso have published more than 50% of their recent peer-reviewedpapers on the subject of climate change (79 individuals in total). Of these specialists, 96.2% (76 of 79) answered “risen” to question 1 and 97.4% (75 of 77) answered yes to question 2. This is in contrast to results of a recent Gallup poll (see http://www.gallup.com/poll/1615/Environment.aspx) that suggests that only 58% of the general public would answer yes to our question 2.
The two areas of expertise in the survey with the smallest percentage of participants
answering yes to question 2 were economic geology with 47% (48 of 103) and meteorology with 64% (23 of 36).
