Test the ability to design an integrated computational framework to predict climate tipping points by coupling ocean circulation, ice‑sheet dynamics, atmospheric processes, and biosphere feedbacks. Assess knowledge of model components and coupling strategies (two‑way coupling, time stepping, scale bridging), governing equations or parameterizations, numerical methods, computational architecture and scalability, ensemble design and uncertainty quantification, data assimilation approaches, required observational and paleoclimate datasets (types, resolution, coverage), and practical validation strategies and metrics (hindcasts, synthetic experiments, cross‑validation, benchmarks). Require a concise design outline that justifies modeling choices, specifies data and compute requirements, and presents a validation plan demonstrating how predictive skill and robustness would be evaluated and reported.
