As for their use of the phrase ‘climate change denier’, that is just disreputable. The expression is doubly false. Nobody denies that the climate changes. It’s a proven fact that it has done many times. The question is whether it is changing as dramatically as the zealots predict, and whether this is caused by human activity. To be a ‘denier’ is a) to be a person who refuses to accept a proven fact, which nobody is doing and b) to be smeared by association with Holocaust deniers, who *do* deny a proven fact, and do so for disgraceful reasons.
