No Epoch Like the Present: Robust Climate Emulation Requires Out-of-Distribution Generalisation
arXiv:2605.22248v1 Announce Type: new Abstract: Climate emulation is an out-of-distribution (OOD) projection task. This is precisely the challenge where modern Machine Learning (ML) methods are most prone to failure. Consequently, while current ML emulators trained on present climate achieve high in-distribution performance, their future reliability under the inevitable distribution shifts of a changing climate remains a critical, poorly understood blind spot. Addressing this challenge requires a fundamental shift in how we understand, evaluate, and design climate emulators. In this work, we f
The increasing reliance on Machine Learning for complex systems like climate modeling highlights the critical need to address OOD generalization issues to ensure future reliability.
Reliable climate emulation is crucial for informed policy decisions, resource allocation, and adaptation strategies given the accelerating pace of climate change.
This research calls for a fundamental re-evaluation of how ML models are designed, trained, and validated for critical predictive tasks that involve significant distribution shifts.
