Climate Risk & Non-Stationarity

Design flood and water-security assessments run on an assumption: that the historical record still represents the system being designed for. These posts sit at the edge of that assumption — reporting what specific events, records, and datasets show, and what that might mean for practice, without overstating what a single event or dataset can prove.

Formal climate attribution is its own discipline, with its own methods and its own experts. What follows here is a flood engineer's read of the evidence in front of them, written to inform rather than to pronounce.
