I wonder what the validity level of that oft brandished data is. I also wonder how many of those scientists know even a hint of valid climate science? My initial guess is that far less than 1% of all persons who can justifiably be classified under the loose term "scientist" have any involvement in climate science.
Depends on which study they are citing, often the people using that figure don't know.
The Doran study is the one most often cited, this is the only one I'm aware of where scientists were directly polled. Setting aside all the issues it comes down to one basic problem. They were asked this question:
What is "significant"? For example if man has been able to change global mean temperatures a minute fraction that could be significant.
The other issue is this 97% is only 75 scientists....
Results show that overall, 90% of par-
ticipants 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 (Figure1). In our sur-
vey, the most specialized and knowledge-
able respondents (with regard to climate
change) are those who listed climate sci-
ence as their area of expertise and who
also have published more than 50% of
their recent peer-reviewed papers on the
subject of climate change (79 individu-
als in total). Of these specialists, 96.2%
(76 of 79) answered “risen” to question 1
and 97.4% (75 of 77) answered yes to ques-
