...of the religion of Scientism, specifically Global Wa -- sorry, "Climate Change," the most zealous manifestation of that religion at present.
The author of the piece does well to point out a few of the parallels between Scientism (whose adherents will deny unto death that it's a faith) and traditional religions, but does not go far enough.
ALL the sects of scientism - most notably evolutionism - have their analogues to holy writ, priesthoods, devils, heretics, sin, savior(s), salvation, redemption, penance and most definitely evangelism. The only thing they tend not to have is moral responsibility from any source apart from or higher than themselves...in short, the Scientism-ists are the gods of Scientism.
And if you do not share their faith, they mark you as the mortal enemy of the earth and of humanity and so feel morally justified in destroying you.
