A Lagoon That Was Dry Land, and the Adriatic Takes Note

The Guardian reported this week that scientists have uncovered ancient hills and swamps that disappeared as sea levels rose across the northern Adriatic, and that the land beneath Venice once lay many miles inland. Over some 10,000 years, the paper says, dramatic changes in sea level reshaped that coastline.

Venice is habitually described as a city built on water. The Guardian's account describes something else: a city built on land that the water eventually reached. That turns the lagoon from a permanent fact of geography into a recent one, and makes the sea the active party in the story rather than the backdrop.

The report presents the work as a reconstruction of the deep past, not a forecast. Its subject is the northern Adriatic, and the Guardian does not extend the finding to the rest of the basin or attach a rate of change to the present century.
