Germany thought they'd have cheap Russian gas from Nordstream. Now they're looking to move manufacturing to the US because energy is too expensive.
Look at it this way, even is CO2 levels are primarily anthropogenic, most of the world isn't willing to do anything about it substantial (i.e. Global South). In which case the Western economies martyring themselves isn't going to change anything.
OTOH, if climate change is not primarily anthropogenic the West martyring itself with expensive green energy decisions is a disastrous mistake.
What is the game theoretical optimal move here?
