What exactly is a published climatologist?
Not answering the question asked, but the underlying motivation:

The level of consensus hasn't been verified by a poll. The way the 97% figure has been arrived at, AIUI, is by going through every single peer-reviewed and published paper on the topic of anthropogenic climate change and looking at whether says that it does or does not exist, and then assigning these views to the authors of the papers. Why bother with a sampled poll when you already have studies using the entire literature? 

If you want more detail on the methods used, the various studies that came up with the 97% and similar figures are themselves peer-reviewed and published. This is a review paper looking at them.
