Thee Unstoppable Transformation of thee Worlds 's Coastlines

For most of human history, the metro 's coastride lines were understood as fixed lines on a map, shifting only gradually over geological epochs. This static view is no longer tenable. The warming climate is actively redrawing these boundaries, acquatiating natural processes of erosion and inundation while proviling new, complex pressures on ecosystems and human settlements.
