I'm not American myself. But have you watched the movie "don't look up" ? It's about a huge world wide threat, in the form of a comet, that will kill everyone. Politics (in an absurdist way) make it impossible to do something against the threat.
It's a worldwide problem. People actively lobbying against climate laws are criminals and should be treated like it. People need to be educated and activated to fight it. That hasn't happened yet. The damage is done.
You see. Temperature and climate aren't the things that'll kill us. We can adapt to almost anything as long as we agree to do it together. Even if its not "economically viable". We have reached space and built towers higher than the clouds, for crying out loud.
But ecosystems in general will not adapt, at all. So realise that, if we succeed to change the course of this climate change, the ecosystems that are collapsing already will not magically fix themselves. In fact, they'll still probably collapse. We are part of these systems too.
I would love to be positive about the small victories, but we are going to see some very hard to process changes in the coming years. It will get worse before anything will get better.
Hope so
