The "shill" phenomenon goes much further than ignorant laypeople.

The AMOC shutdown isn't merely "possible" and due "this century". The math of the dynamics of complex systems shows the current behavior to be signs of a phase transition in the process of happening. The speed of that shutdown isn't "decades" either, it's more likely just years.

The voices of "experts" telling you it was all some incomprehensible conundrum should deeply worry you. They're either not being honest or they're no experts.

People are stupid. I almost had a fight with a friend I have seen in a long time, a usually smart person, that wanted to convince me that solar power is more polluting than non-renewable alternatives. He’a not a shill, he is a farmer and like many just believes the propaganda and the skepticism. One of the biggest flaws of human rationality is wanting to believe that ‘the man’ is lying to you and the stupid conspiracy meme on Facebook has a valid point. We all have seen the American public completely implode with the COVID and mask and antivax idiocy.
