Some major compilations

I've also tagged authors included in a few major compilations of climate science articles. These are not petitions or calls for action, but further illustrate the author's standing in the literature.

SotP09: Science Magazine's State of the Planet 2008-2009 collection of articles from the journal plus added analysis; covers recent climate change research published in Science
CVX: Climate Variability and Extremes
C&O: Climate Change: Critical Concepts in the Environment and Physical Geography, Frank Chambers and Michael Ogle, eds. [Routledge, 2002; 4 vols.; ISBN-13 978-0415276603] This extensive collection covers much of the early history of climate science, as well as selected highlights of more recent work.

For details on these declarations and how I've annotated for them, see notes on open letters

Names are sorted in descending order of number of published works that match the word 'climate' in Google Scholar. This total could include non-refereed pieces such as commentary, editorials, or letters to the editor. (Note that citation stats were collected by hand, over a few months, so exact order might vary slightly as papers continue to gain citations as time passes.)

Anyone working in the field of climate science should have a significant number of hits on this search. The median number for IPCC wg1 authors is 93 articles; for all of the roughly 1800 authors I've checked up to July 2009, including skeptics, the median is 56. For the 386 names I've checked so far who were signers of a climate skeptics' statement, the median is two (2).

70% of the skeptics have fewer than 10 published works that mentions of climate and 60% have fewer than five. At the top of the rankings, there are 25 skeptics who have more than the overall median of 56 works mentioning 'climate', and just 12 above the IPCC median of 93.

In the overall list, there are 908 names with 56 or more works mentioning climate, and 593 names with at least 93 works. In this light, self-declared skeptics make up only 2.75% of the first group, or 2.03% of the second.
