“This site provides information on over 2400 climate scientists and authors who have signed public statement on climate change. This includes both statements calling for action to cut greenhouse gas emissions as well as ones that argue against such action.
Each name has a link to the person’s web page at a university or national research lab, where one was found. I used Google Scholar to look up what each author had published on climate, and how widely cited their work is. This information lets us compare the credibility of those arguing against curbs on greenhouse emissions versus those supporting them.
The upshot of this comparison is that the climate change “skeptic” position has very few authors with any standing as climate scientists.
While there have been several public declarations challenging the basic science or the need for any response like emission reductions, including some with a large number of names, the great proportion of those signers turn out to have little or no qualifications on this topic.”
