This implies that the “facts” of Glo-Bull warming lead to the fanaticism. I would say it is the opposite - The fanaticism of the Leftists to control all around them leads them to adopt what they see as the most effective vehicle to get there, Glo-Bull warming.
Glo-Bull warming isn’t a religion in and of itself, but it is one part of the current doctrine of the Leftist religion, which seeks to bring us all to their version of nirvana, which naturally would be under their “enlightened” tyrannical control.
"A fanatic is one who can't change his mind and won't change the subject." - Winston Churchill
