I wouldn't think it would matter at all. Nobody would know who the scientists were, so you wouldn't even need to use real ones for the same effect. I don't even think most warming deniers would really care, and it wouldn't even spend a week in the news cycle, if aired at all. Do a video of them sacrificing a child to Beelzebub, and maybe you'd get some attention.

Just telling everybody that you were told that this meeting happened through secret messages from a secret high-level traitor from the Soros Foundation would work just as well. It would work on hundreds of people even if you said that you were receiving these messages psychically or encoded through subtle changes in reruns of Law & Order.
