Heatline
Ocean heat is no longer background context. It changes the operating envelope for ports, sea lanes, and cargo timing.
Where the heat lands
A small set of freight corridors carries a disproportionate share of thermal and storm exposure.

Adaptation ledger
Resilience buys time and optionality, but it shifts cost into route diversity, inventory, and port hardening.
Diversify routes+ optionality
Build buffers+ inventory cost
