Sea Level, Eustatic and Accelerating
Captions available
The idea
Eustatic sea-level change is global, from land ice or the seafloor's shape. Over twenty thousand years the sea rose about one hundred twenty-five meters from glacial melting, then slowed to about zero point seven millimeters a year, accelerating from about eighteen seventy.
In practice
Seawalls, groins, and dams starving beaches.
Where people slip
Anthropogenic warming is the anchor's cause for the acceleration.
