Policies are not perfect, and they will be created with input from all parties. What you highlight feels like an artifact of these policies not being hard line enough. You are of course right that it is effective to show natural disasters and explain that these will be more frequent if we do nothing, when you do that people will make the wrong conclusions how that effects their daily lives. We know that we use too much resources, and this is going to have catastrophic consequences in the future if we do not change how we use them.
It is not obvious who you are arguing against, it feels to me that you are against the people who make climate policies weak, and the very same policies.
Lets talk specific, we had a plastic bag ban here in Sweden. It was vilified as not efficient. In the end it was effective according to research after the ban was lifted and an even extreme approach would have been even better.
An actual leftist party would ban private jets before it banned natural gas in homes.
The Democrats are a neoliberal conservative party. They'll always put the interests of Capital first.
I sympathize, I'm not sure what Americans are meant to do about their utterly captured government.
