Hear me out, please...
I'm not saying we shouldn't be doing all we can to ensure the survival of our planet. I'm the guy who started paper recycling in my school system at ten years old. I 100% think America should have been in the Paris Accord.
But something interesting happened when President Trump said "no". People I have never seen care about the environment are suddenly interested and vowing to change their lifestyle. Businesses decide to follow the new standards even if the government won't enforce them. Donations in the millions are being made to cover what America would have pledged to the global cause.
None of this would have happened if President Trump said "yes".
If he has said "yes" things would have gone on as normal, few people would have cared, and many would try to get out of following these new regulations. Now, the country is fighting for it. By saying "no" it forced the rest of us to say "yes" and step up and take accountability for it.
Maybe this is part of the reason God allows bad things to happen or even flat out says "no" to us at times. If He just said "yes" would we live as if it were important? I read a book the other day where the author made the point if Jesus didn't leave for heaven, would we be even more apathetic than we are now, just expecting Jesus to take care of it all? Instead of being Jesus for people we would step back and simply point them to Jesus and have remove ourselves there?
Sometimes others saying "no" is a good thing, it forces us to live "yes".
