A climate plan that requires significant sacrifice might work on planet Vulcan, but not on planet Earth. Assuming otherwise is nonserious. We need a plan that will work with only homo sapiens to carry it out, and that means a plan that takes into account human selfishness and shortsightedness. It means a plan that will appeal to China and India and Brazil and the rest of the world. It means a plan that will somehow reduce atmospheric carbon a lot even while most of us sit around fat, dumb, and happy.
The only such plan I can think of is one that increases global R&D spending on climate mitigation by, oh, 10x or so. Maybe 20x if it’s feasible. This money would be spent on developing new sources of clean energy and energy storage; reducing the price of current sources of clean energy; figuring out ways to remove carbon from the atmosphere; and pretty much anything else that seems remotely useful. The fruits of this research would be turned over to the private sector for free, and they would then compete to sell it all over the globe. This would harness human selfishness instead of fighting it. It’s not guaranteed to work, but unlike the GND and similar manifestos, at least it’s not guaranteed to fail.
