Eos has just published the results of a survey of 3146 Earth Scientists conducted by Peter Doran and Maggie Kendall Zimmerman. The graph below shows the results for this question:

Do you think human activity is a significant contributing factor in changing mean global temperatures?

The 97% of active climatologists is 75 out of the 77 in the survey. Doran and Zimmermann say:

While respondents' names are kept private, the authors noted that the

survey included participants with well-documented dissenting opinions

on global warming theory.

I'm guessing that Lindzen and Spencer are the two that said "no".

The difference between the opinion of the general public and the scientists is striking. For comparison, despite the ongoing efforts of right-wing pundits here, 80% of Australians answered "yes" to a similar question.

James Annan is a little peeved, because last year Eos refused to publish the results of his poll on the basis that Eos did not publish the results of opinion polls. I think it is good that they have changed their policy, but of course they should have published the results of the other poll last year.

My thanks to reader MarkG for sending me a copy of the Doran and Zimmermann article.

Update: Here are links to the EOS article and the full report on the survey. (From Doran's home page.)
