The US is not the entire world (thank goodness). In the world, you are in a minority. In this country (which is being ruined, per your assertion), congratulations, you're part of the problem.
If you would leave your area and see more of the world, maybe you would have known this. But I'm sure I've been abroad more in the past year than you have in your life.

Corporations and misinformation has been very successful here. Congrats on being duped. The US is right between Nambia and Vietnam in terms of seeing climate changed caused by human action - behind even Australia! At least we are decent in awareness, and even as seeing it as a threat (63%). The US is in the bottom portion of those studied (86 out of 128) in terms of concern, and below the average (49, average is 56).
If you spend time visiting Japan, Europe (outside the UK), and Latin America, the fact that this is still a question in the US is baffling. If you visit Russia and war-torn, impoverished sections of Africa, then you will find your opinion reinforced.
