Sea level rise in Venice

Common card · No. 481735

Rising sea levels pose a major threat to Venice, Italy. Known for its old structures, layers of history, and unique ties to the water, Venice faces increasing risks of major flooding and damage due to both rising sea levels and subsidence. Studies show a range of future projections for sea-level rise in Venice, with the likely outcome by 2100 being a rise of 21–52 cm. Low elevation, proximity to the Venice lagoon, and the city's series of canals make it particularly vulnerable to sea level changes. Flooding is a frequent and damaging disruption that poses threats to cultural heritage, biodiversity, public health, and tourism. Venetians have implemented measures to mitigate these changes, such as glass barriers, elevating lower lying areas of the city, and MOSE, a series of floodgates to protect the lagoon from high tides. Research paints a troubling picture for the future of the city and its surrounding areas if current climate trends continue or intensify.
