The increase in flooding in Venice is explained by the combined effects of land subsidence, which is sinking the city, and climate change, which is causing a global rise in sea levels.
Of these 26 centimeters, about 12 are linked to the fact that the Venetian islands are sinking; this is due to the withdrawal of water from the aquifer, this geological formation located under the Venetian lagoon. Further measurements point out that the sea level is still rising by 2.4 mm per year.
The Venetians also fought the floods by raising roadways and footbridges and by building dykes; but this strategy now damages the architecture of the city. In 2003, the Mose project was launched with the idea of protecting Venice against worsening floods.
