Venice faces significant sea-level rise driven by both climate change and land sinking
In short: A review of historical data and climate models found that Venice has experienced a steady relative sea-level rise of about 2.5 mm per year over the last 150 years. While global sea levels are rising, nearly half of this increase in Venice is actually caused by the land sinking beneath the city, a process known as subsidence.
The study synthesized historical tide-gauge data and recent literature to separate these factors. It highlights that while climate-driven sea-level rise is accelerating, local land movement and regional ocean circulation create unique risks for the lagoon. A major limitation is the lack of satellite data for the specific Venice area, making it harder to reconcile different measurement tools.
Why it matters: Understanding Venice's future requires looking at both global warming and the local geological sinking of the land.
