Agreed. We're past the point where culture can shift in time to turn the wheel. Only technology shifts quickly enough to do so.
EVs and wind/solar energies are examples of technologies which are so much better than the alternatives that they're succeeding at reducing emissions faster than consumption can grow to catch up. We don't have the time to get enough people together to mandate that the front row drives a Tesla instead of a Ford, nor to mandate that they produce wind farms instead of coal plants, but they're doing so of their own accord - and demand for them exceeds production capacity by a large margin - because the electric car is better and the wind energy is cheaper. As you say, we now need parachute tech.
Tough problem. Once you start doing back-of-the-envelope math regarding the masses and volumes you are talking about here as well as the time remaining it quickly tends to require all kinds of unobtanium, besides the obvious climate impact of engineering such a solution in the first place, because it needs to be a net positive otherwise you may as well not start.
Funny thing: the only system that I'm aware of that could do this on this scale and cheap enough is called biology, and it operates on a timescale that is too slow to make it work in time.
Unfortunately some of those technologies haven't been around long enough to fully understand the full lifecycle cost. We are burying wind turbine blades in some places and the total emissions of an EV are sometimes more than a small efficient gas automobile when total lifetime emissions are considered.
Still these technologies are succeeding in the marketplace and if they can continue to improve we may solve many of those problems as we go.
I'd need to see the data on that EV comparison. And earth-to-earth carbon emissions of wind turbines are very unlikely to be higher than coal or nuclear.
Regardless, people aren't buying small cars with efficient gas engines. They're buying trucks and SUVs they don't need. Which will likely continue until it's clear gasoline isn't going to get financially cheaper.
