Why? So that the governments that pay their salaries can seize yet more wealth and power for themselves.
The facts are very, very clear. “Man made climate change” is to “science” as Avril Lavigne is to “sober”. It IS a hoax, and that is an absolute, irrefutable fact. There are in fact a great many scientists who do not support this hoax, but they are being silenced. To speak up against this scam is to throw your career away, which is why there aren’t MORE scientists speaking up.
The MMGW crooks take the same approach to “science” that the Nazis did: Say what we tell you to say or lose your career. They have obtained their “consensus” like the Nazis did: By means of extortion and bribery.
There is a reason why no proponent of MMGW will publicly debate a skeptic: They know they will lose. They know that their success is entirely dependent on intimidating anyone who questions them, they know that their position cannot survive rigorous cross-examination.
