New Preprint **Not yet peer-reviewed** How would the climate differ if we exceed a given temperature and then return to it via carbon dioxide removal, versus if we stop emitting CO2 at that temperature and let the climate system evolve over the same length of time?

I don’t put AI for discovery or understanding anywhere near the pedestal some hold it. And certainly not on par with physics and math. Still AI can offer solutions where before we had few options. Eg improving and accelerating modeling. Helping analyze obs. That’s a good thing if it’s done well.
