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.
