Thanks for the name besty!
I was able to google it and found some interesting articles realted to that study and it backs up what I thought about the numbers.
Here is a link and I'll post a partial quote from one site:

97% of climate experts agree humans are causing global warming.
I recently heard this claim on my own threads. I looked at the source (the study Doran and Zimmerman 2009), found some problems, and then wrote back on my threads. However, I have seen this claim so many times that I believe it would be good to make a post about it. I also e-mailed several prominent climate scientists who would be considered 'skeptics' to get their opinions on the study. Their responses are displayed at the end of the post. In this post I briefly comment on past responses to the study, then break my post into three sections. The first will focus on the flaw in the study (the second question), the second will look at the motives of the researcher, and the third will be posting responses from prominent 'skeptical' climate scientists. First I'm going to address a common response to this study. In this post at The Hockey Schtick, it is pointed out that the 97% statistic is based on only 79 climatologists, and that those participating were self-selected. There are two concerns here. The first is sample size. While climate science isn't a massive field, 79 participants is fairly small. To claim definitely that 97% believe this or that you would need to poll significantly more people. The second concern is the fact that the scientists were self-selected by an online survey. This may not have led to a representative sample.
Other concerns with the study deal with numbers behind it, or other reasons to consider it a poor study. However, these aren't my primary concern. My concern is the actual questions asked in the study, which I will show in a moment.
The study on which these claims are based is available here. It is an paper by Peter Doran and Maggie Kendall Zimmerman written in 2009, entitled "Examining the Scientific Consensus on Climate Change". Here is the citation:
