 # E3SMv3 emulator checkpoints for the E3SM AI group hackathon, 25 September 2026
 
 > **Not fit for forcing or scenario experiments.** Both checkpoints reproduce the E3SMv3 historical run well
-> when the other half of the climate system is handed to them, but neither responds to a change in forcing
-> physically: the atmosphere uses CO₂ as a clock, and the ocean reads its answer off its upward-longwave input.
-> Use them to study how an emulator represents the climate, not what the climate does. Results from them show
-> how the model *represents* forcing.
