Even if CO2 wasn't a factor (and I'm not saying that's the case), the geopolitical stage is set in large part by those who control fossil fuels. The whole middle east with opec has dictated our behaviors by virtue of resources. It would be far better to develop sources of power which do not depend on outside sources like solar.
Carter understood this, but Regan killed it. Trump will be as bad or worse I fear.
The good news is that we are already doing this and it seems like the renewable train is unstoppable regardless of government influence. That being said, the idea that the head of the EPA is still trying to deny objective scientific reality is insane.
I don't even know what to say about this administration anymore. It is the first one that feels no need to confirm statements or policy to reality. This is probably a big political advantage but it is also a large 'functioning society' disadvantage.
