I've also started providing two versions of each listing: one sorted in descending order of number of citations (starting with the fourth-most-cited paper for each author, then sub-sorting on the #3 paper and the #2 paper as needed); the other version, new this month, is sorted on the number of papers mentioning "climate" by that author. I found this addresses the issue of people with long careers in some other field who begin making pronouncements on climatology without ever having published on climate themselves - such as phycists Antonio Zichichi and (particularly) Freeman Dyson. Both ranked in the top 100 when sorting on most citations to their entire published works - but these guys published very little academically actually talking about climate. Freeman Dyson has just 23 hits on "climate" in Google Scholar, versus over 435 in total, and a high-ranking 318 cites to his fourth-most-cited paper (which was nothing to do with the climate.) Zichichi? He's got six.
Sorted on matches for "climate," the list now gives more of an indication of which names are in fact climate scientists themselves. It also highlights just how far down the barrel the skeptic groups are digging to find names to fill out their open letters and political ads.
I've made separate pages for just the Cato ad signers, the "scientists" who signed the Manhattan Declaration, and one specific to Martin Durkin's overwrought documentary "The Great Global Warming Swindle." In this page I list those who appeared in the film, plus the (larger) list of scientists who signed a letter of complaint to
A similar trend carries through to other new sub-tables I've set up, including the one limited to just Canadian authors. The median number of papers mentioning "climate" for this group is 39. Four Canadian contributors to AR4 wg1 fall below this median value, while around 30 meet or exceed that level; AR4 wg1 included five of Canada's ten authors with the most papers on "climate" (of those I've catalogued, anyway).
Only three of the top 50 Canadians by number of articles on "climate" have signed skeptic declarations or letters: Cornelius van Kooten, Jan Veizer and Ross McKitrick. Of these, only Veizer is a scientist; the other two both write on economics.
I'll leave for another post the particulars of my table of signers of the 2009 Cato Institute ad directed at President Obama's stance on climate.
