The Center for Inquiry’s press release on this issue said:
After assessing 687 individuals named as “dissenting scientists” in the January 2009 version of the United States Senate Minority Report, the Center for Inquiry’s Credibility Project found that:
- Slightly fewer than 10 percent could be identified as climate scientists.
- Approximately 15 percent published in the recognizable refereed literature on subjects related to climate science.
- Approximately 80 percent clearly had no refereed publication record on climate science at all.
- Approximately 4 percent appeared to favor the current IPCC-2007 consensus and should not have been on the list.
Further examination of the backgrounds of these individuals revealed that a significant number were identified as meteorologists, and some of these people were employed to report the weather.

To which I would add, there are more than 2.6 million scientists in the USA alone.
700 is thus a microscopic number assessed globally, even if the entire 700 were legitimate practicing scientists, which is far from clear.
The senator also produced an earlier list of 400 “scientists”, most of whom had little to do with climate science even when they were, in fact, scientists. The earlier list is discussed here: http://rabett.blogspot.com/2007/12/makin-list-checkin-it-twice-here-is.html
