That ship sailed already. The political climate is small scale compared to climate change. We should dealt with climate change 40-50 years ago but we kept kicking the can down the road.
Trump won't do anything about climate change because he probably doesn't believe it in. The Democrats aren't forceful enough to take action either. Mandating people drive EVs won't do anything, nor will any of the other programs they've come up with. Tackle energy generation then manufacturing, after that we can discuss me buying an EV and sorting all my waste.
So while yes, the political climate is undoubtedly going to cause problems, I think they're going to be minor in comparison to climate change. Massive hurricanes, destructive storms, drought, heat waves, and crazy blizzards are only the tip. When population centers are no longer habitable and there are millions of climate refugees, thing will get interesting quickly. Leaders should be scared of that because if people lose everything they'll have nothing to really live for. Having a bunch of people with nothing to live for who are pissed at the leaders never works out well for the leaders.
Honestly I wish we had a presidential candidate who was like Reagan when it comes to foreign policy (ie killing the Soviets) and Gore when it comes to things like environmental policy with the charisma of Obama.
