No offense, but you obviously did not review that board closely. It is dominated by skeptics and voluminous information and links which can provide one with great knowledge.
Perhaps I couldn't navigate on that site properly. Thank you for the link. The sites that I ultimately found most useful are: http://bishophill.squarespace.com/ , and http://wattsupwiththat.com/ .
My fundamental PR problem is the Arctic ice cap images. AGW is a very complex issue due to the volume of misinformation and lies generated by its proponents. However, discussing the issue, with a business associate for five minutes over a coffee, for example, inevitably ends with their disbelief that the images could be a lie. I'm getting better at it, but it's tough. This may be unique to Canada, but afterward I am considered suspect, which does not encourage people to speak up.
