No one is being forced. At least not yet. CA is looking to be all EV sometime before 2040. A lot can happen in 16 years.

Since these types of conversions take a long time, "not yet" still makes it's way forward in time. If CA sets a policy that all new vehicles have to be EV's in 2035, that's going to have an impact on investments and manufacturing decisions today. It's not going to take 11 years for the effects to start being seen, and affecting the options available to consumers. As you might expect, automakers are devoting a lot more of their long term investments into plants and research into EV's, not ICE's.

I've already accepted that is going to happen. Too much inertia, too much resistance to change, too much denial, too much money, etc. Nothing can stop it now.

We're not going to have catastrophic climate change. Or at least, not catastrophic to us in the U.S. and other OECD countries. We will almost certainly have 2.2-2.7 C increases in temps....but while that will be bad for a lot of people in a lot of places, it's not likely to be all that terrible for us here in the U.S.
