> In an effort to limit warming poised to dry out the state, California pledged to shift to 100% clean electricity by 2045.

Well moving to sustainable energy is good, but California being on 100% clean electricity won't have any measurable effect on its warming.

I guess global warming will be solved through lots of different actions and changes, even though none of them will make a measurable difference on its own.

Also 2045 seems like a quite late goal by now, leaving all the options open. Have they moved in that direction already and have a head start?

CA is already at 40% electric from green sources. I don't know their plans, but in general I would expect by 2035 they will be at 95%. However that last 5% will be the long tail of weird/hard things.
