Maybe, except that there's little evidence that even one tiny prediction of the harm has come true, and the assumption that we ought to be deliberately manipulating the environment, blocking out the sun, modifying the air, and also taxing people trillions of dollars and politicizing every single industry and even human breath seems like 1000x the problem and negative externalities versus protecting our basic liberties.
I think having the freedom to progress, protect more people, produce more energy in more varied and creative ways, raise the global population out of poverty, and having the humility to consider that we might not be able to "engineer the world" any better than nature, or that deliberately causing extreme widespread poverty and allowing arrogant centralized governments to control every aspect of our lives might not be a "better" course of action.
