on how severely we need to cut emissions (and how much carbon removal we'll need) to keep climate within a +1.5 C ∆T spec

It’s never been about time either. I’ve concluded there are no collective action mechanisms capable of manifesting that kind of intentionality. Not even if the most advanced authoritarian world government under most benevolent version of Kim Jong-un appeared magically tomorrow
A plausible pathway is some sort of secret billionaire unilateralism. I wrote a story about that in July 2021 and then damn Neal Stephenson published a whole novel with that premise in November. I like to think I scooped him 🤣
haha yes
my cofounder Steve was writing a book on geoengineering too and kept mining me for ideas. it was a good book, but the Stephenson drop brought him to dismay
i guess it depends on the scale and costs. re geoengineering the aerosol stuff could be super cost effective, and highly leveraged in preventing positive feedbacks.
but we haven't done the experiments to confirm it, it's guessing
My point is, it’s not the technology difficulty thay will stop us (though that part is hard too), but political action difficulty. We learned that with Covid. Moonshot vaccine project actually worked… and then doubt merchanting on talk radio shows gave away half the win.
