How can you tell whether those who are listed on that webpage as signatories:
- Are actually scientist; ???
- Actually have expertise in environmental matters relevant to warming ???; and
- Have actually done any scientific work on the causes of warming ???
I find the debate over warming interesting and it seems to me that there is a split in opinion among credible scientist over (1) whether there is global warming; and (2) if there is, whats causing it. But my quick scan of that webpage didn't leave me with opinion that it has much credibility, on the subject.

Simple Question, What information have you seen to refute what these scientists are stating?

Qualifications of Signers
Signatories are approved for inclusion in the Petition Project list if they have obtained formal educational degrees at the level of Bachelor of Science or higher in appropriate scientific fields. The petition has been circulated only in the United States.
The current list of petition signers includes 9,029 PhD; 7,153 MS; 2,585 MD and DVM; and 12,711 BS or equivalent academic degrees. Most of the MD and DVM signers also have underlying degrees in basic science.
All of the listed signers have formal educations in fields of specialization that suitably qualify them to evaluate the research data related to the petition statement. Many of the signers currently work in climatological, meteorological, atmospheric, environmental, geophysical, astronomical, and biological fields directly involved in the climate change controversy.
The Petition Project classifies petition signers on the basis of their formal academic training, as summarized below. Scientists often pursue specialized fields of endeavor that are different from their formal education, but their underlying training can be applied to any scientific field in which they become interested.
Outlined below are the numbers of Petition Project signatories, subdivided by educational specialties. These have been combined, as indicated, into seven categories.
