The issue is politics and nothing else, and people rationally concerned about various public welfare issues, including climate change, seem afraid to fight. So to avoid a fight, they pretend that if they present a strong enough rational argument, the right will accept it. They've kept their heads in the sand for decades, and humanity has shown they can do that perpetually.

The right is focused on politics above everything, and their singular tactic is aggressiveness at all times. They won't back down - why would they? Nobody has made them pay a price for it. To win, to do something about climate change, people will need to fight a political battle against a confident, aggressive, well-organized, well-resourced enemy. That is all that matters.

The good news is that if you punch a bully in the mouth (politically), they quickly change their tune. And the good news is that their ideas are ridiculous and corrupting (to them). But so far, I haven't seen anyone willing to throw a punch (and if someone does, such as some progressives, the rest of the non-right turns on them; they don't want to provoke a fight!).
