97% of active climatologists agree that human activity is causing global warming  

Tim Lambert has a post on the scientific consensus about global warming - 97% of active climatologists agree that human activity is causing global warming.

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.
