Climate policies have failed. They're all either empty signaling exercises (carbon offsets, CAFE standards) or economically ruinous proposals to deliberately impoverish people (degrowth). The Paris accords penalize developed economies while giving developing countries a pass on emissions and an unfair advantage in trade. This idea that we can just sit down in a room with all the world's leaders and agree to just reduce emissions is a fantasy.

The real climate policy we need, and one we might just get from the incoming administration, is support for startups that explore new geoengineering technology. We've on our way to being Kardashev type I civilization, and as such, we should establish explicit closed-loop control over our climate.
