It's that easy!

In the US, there will always be a critical mass of voters ready to end the careers of anyone who tries to do any of the above.
I'd add that buses for the most part don't help, and we should revive the trolly systems that Goodyear intentionally put out of business, and furthermore build out mega railway projects to take long haul trucks off the road.
Railways need to be nationalized, and we need to make it easier to live rurally without the need for multiple cars and lots of gas consumption.
And we need to start building a bunch of new nuke plants like 30 years ago.
None of that will start to happen until it is way beyond too late though. And even if the US got onboard with the program, there will always be 40% of the planet who won't. So fuck it, enjoy nature while it lasts. We'll turn the sky white to geoengineer away some of the solar radiation, but the line will continue to go down from here.
I agree with everything you said except for your last paragraph. Scientifically speaking, it is not to late. Politically it is, but politics can and have swung wildly. Our best bet is the younger generation shows up to the polls and votes in green candidates. My local area has had some good success with this at least.
As for the geoengineering, I can see that being the unfortunate case. I'm concerned it's going to be a far dumber and dangerous version of it though, like intentionally nuking a remote islands a couple times to start a mild nuclear winter.
