Man caused global warming is one of the most brilliant and insidious scams in human history. Imagine if you could convince a significant number of people that every natural, inconvenient phenomenon was due to nefarious activity by your political adversaries? It cleverly focuses animus for natural events on people you don’t like, costs nothing and requires no effort to precipitate, and endlessly feeds hatred and derision against your foes. The only downside is that your political constituency would be populated exclusively by morons, but the power you could wield would nonetheless be real.
Calling your enemy a witch thereby getting them killed I think ranks higher on the scam scale, but replace "Official Priest" with "Official Scientist" and it becomes clear history is once again repeating itself.
It's Witches -- The Witches caused it! We need to burn them. ;~))
I guess the 'Age of Reason' that began in Europe 500 years ago is over and we're heading into a new Dark Age where only the alchemist's computer climate model matters, not actual measurements. And God help the heritic who dares to question the divine model.
