Compound and Cascading Extremes: Understanding & Predictability for enhanced resilience
Session ID#: 249228
Session Description:
Compound extremes—where one hazard triggers or amplifies another—pose global risks to water, food, energy, and infrastructure. Examples include heat-drought-wildfire sequences over multiple continents, compound flood events driven by precipitation and storm surge. Despite their growing societal impact, predictive understanding of these rare yet disastrous extremes remains limited. Therefore, in this session, we welcome studies that· (1) Integrate Earth observations to characterize connected/compound/cascading events over local to global scale, (2) Apply complexity or statistics analysis, causal inference, machine learning, or process-based modeling to unravel cross-system/cascading linkages. (3) Develop early warning for integrated driver-hazard-impact probability assessment. (4) Quantify the impacts of cascading hazards on critical infrastructure and the probable counter-mitigation/recovery strategies. (5) Evaluate changing feedbacks between the carbon, energy, and water cycle with connected extremes. The session will convene hydrologists, atmospheric scientists, data scientists, and risk analysts to showcase innovative methods for resilient and domain knowledge-integrated decision-making in a changing climate.
