Assess learners' ability to analyze major sources of uncertainty in climate model projections—including structural and parametric model errors, scenario/forcing uncertainty, initial-condition/internal variability, downscaling and observational uncertainties—and to interpret ensemble outputs, attribute uncertainty contributions, and translate those findings into implications for regional adaptation planning (risk prioritization, robust/adaptive pathways, monitoring priorities, and stakeholder communication). Scope: advanced concepts, ensemble interpretation, and decision-relevant recommendations for practitioners.
