Most (27) of Harris's 31 “experts” fall nicely into the category of “usual suspects,” having all signed the infamous Letter of 60 , demanding that the Canadian government take NO action on climate change. (Kudos to Harris for his success on that front, as well.)
But there are four names here that weren't on that letter. Dr. David Legates (University of Delaware), Dr. Garth Paltride (University of Tasmania, Emeritus), Hans Erren (a “geophysical consultant” from the Netherlands) and Dr. Robert Balling.
Balling  has been around for a while, taking money from energy companies (Exxon, etc.) and denying climate change; he must have been out of town when they created the Letter of 60.
And Legates also pops up on the Sourcewatch list  of industry-friendly experts. But Erren and Paltridge are new.
Well done Tom. If you can find another living, breathing, climate-change denying “expert” anywhere else on the planet, let us know. We'll publicize his name and website right here on the DeSmogBlog.
