The Paris accord is not worth the paper it’s written on.
It’s non-biding, it has no enforcement, and the goals where self imposed and for some countries ridiculous.
Even if it’s not for the right reasons, the US leaving might force world leaders to actually do something.
What kind of message is that sending?
If the US creates an alternative to the Paris Agreement that has more teeth, there might be an opportunity cost. Until then, this is the best thing we have.
The message being sent here is, "in the global coordination problem of climate change, I'm the defector and the freeloader, and I need to be coerced to take part".
Seems like very obscure logic.
Hah! No, the Paris accord, the "no enforcement, and the goals where self imposed and for some countries ridiculous" Paris accord is the world "doing something".
Even that will not be reached.
