Coastal Cities Race to Adapt as Sea Levels Climb

Rising sea levels are no longer a distant threat but a present reality for hundreds of millions living along coastlines, forcing cities into costly and urgent adaptation.

Some governments are investing in sea walls and flood barriers, while others are experimenting with floating neighborhoods and managed retreat from the most vulnerable zones.

Experts stress that adaptation must go hand in hand with emissions cuts, warning that engineering alone cannot keep pace with unchecked warming.
