Water is creeping toward places people still call home.

Across the world’s coastlines, something subtle is unfolding. Places that once felt permanent are beginning to look less certain, as tides push farther inland and storms leave behind water that no longer drains away as quickly as it once did. Residents in some towns have started noticing the same unsettling signs: beaches narrowing, wells turning salty, roads flooding on ordinary high tides. None of it happens all at once. The changes arrive gradually, season by season, until the pattern becomes impossible to ignore. Scientists studying these coastlines say the stories emerging from a handful of communities offer an early glimpse of what rising seas may eventually mean for many more places.
