Authors are ranked on two factors: their level of peer-reviewed publication on climate, and their work's impact as measured by citations to an author's works. Both sets of numbers were gathered from Google Scholar (GS). This source was selected because it is freely available without subscription to the general public, and provides a broad index covering peer-reviewed, scholarly journals.

Q: Why not the most cited work? A: To emphasize depth, minimizing any 'coattail effect' for minor co-author of one big paper.
Q: Why 4? A: I had to pick a stopping point; I found I could collect the citation count for an author's top four most cited works on Google Scholar from a single screen without scrolling.

Names are shown with standard acronyms for any learned societies to which they belong. Learned society fellows are generally elected by the society's general memembership in recognition of outstanding contributions in their field. Most societies elect fewer than 1% of their members as fellows.
