Assess students' ability to analyze Earth's climate feedback mechanisms and potential tipping points. Tasks include distinguishing positive vs. negative feedbacks (e.g., ice–albedo, water vapor, cloud, permafrost carbon release), identifying key tipping elements (AMOC, Greenland ice sheet, Amazon), interpreting time-series and model outputs for threshold behavior and hysteresis, and evaluating implications for climate stability and policy using quantitative evidence and reasoned argumentation.
