Here it is again.

Powell's post (on principle, I refuse to call it "research" or dignify it with any other language that suggests it has merit) did a search of 10,885 articles that he said were peer reviewed. In his judgment, only two articles "rejected" anthropogenic global warming.
What did the rest say? We have no idea.
Powell said the 10,885 articles were ones "with" topics or keyword phrases such as "global warming," "global climate change" and "climate change." No further details are provided regarding content.
The obvious questions for Powell are:
-- How many of the articles "with" references to the climate were clearly addressing anthropogenic global warming, as opposed to changes in the climate that may have occurred through natural variants?: He doesn't say.
-- How many articles specifically support the premise of anthropogenic global warming?: He doesn't say.
-- Of those that do support the premise, how many indicate that they believe the affect on the climate is significant enough to be a concern?: He doesn't say.
-- Of those that support the premise, how many (if any) provide any evidence or valuable research into the matter: He doesn't say.
What can we conclude from this? Absolutely nothing.
However, his misleading pie chart creates the deliberately false illusion that there is some type of "consensus," when the content of his post shows he has found no such thing.

If someone really wanted to know the answer, he/she would survey the researchers with a straight-forward question:
Do you believe that man-made carbon dioxide emissions are the primary cause for recently recorded increases in the Earth's temperature?
-- Yes.
-- No.
-- Don't know.
I prefer evidence over surveys and polls. But for those of you who think surveying the climate researchers' views is important, that would give you an appropriate breakdown of responses.
Unfortunately, I suspect you might not like the results. That's probably why the direct question never gets asked (eg., Doran).
