Analysis of climate skeptic organizations

Just a quick hat-tip to Jim Lippard for his recent post looking at the credibility of organizations and scientists associated with the AGW denial movement.

His analysis looking at the age/seniority of skeptics vs non-skeptics is particularly interesting, pointing to the denier movement dying out along with its dinosaurs:

Citation counts of 4th-most-cited >= 200:
IPCC WG1: N=83, 12 w/o year, N=71, average year of last degree = 1981
Skeptics: N=13, 4 w/o year, N=9, average year of last degree = 1965

Citations counts of 4th-most-cited >=100:
IPCC WG1: N=201, 51 w/o year, N=150, average year of last degree = 1983
Skeptics: N=38, 15 w/o year, N=23, average year of last degree = 1968

All IPCC WG1 vs. AGW-skeptical document signers:
IPCC WG1: N=623, 208 w/o year, N=415, average year of last degree = 1989
Skeptics: N=469, 346 w/o year, N=123, average year of last degree = 1973
