Absolutely.

> ... because none of us know the final truth about the immensely complex system that is the Earth's climate.

Even if we did know, don't block people going to the hospital to try to prove your point. First, it's insanely un-empathetic, to the point of sociopathy. And, theoretically, you probably claim to care about the climate because climate change is going to hurt people. Second, it's not going to win friends for your movement or viewpoint. It's counter-productive, no matter how urgent you think climate change is.
