Coastal Protection Programme Anchors
Dated sea-level projections, coastline and low-lying land shares, Coastal and Flood Protection Fund injections, and Long Island scale figures — with pathway and baseline labels on every projection row.
Coastal Protection Programme Anchors
Use each row with its emissions pathway, baseline period, and unit. Coastline length is not seawall length. Narrative lives in coastal protection.
