Researchers have developed a new method for optimizing training datasets to improve the generalization of machine learning climate emulators. By using a differentiable Simple Climate Model (SCM), they can iteratively update training data to maximize emulator skill. This approach, demonstrated to outperform emulators trained on standard ScenarioMIP pathways, suggests that a small number of dynamically rich scenarios can yield greater value for emulation and system response characterization than a larger set of traditional emissions pathways, especially in compute-constrained environments.
