New research by Italian scientists estimates that parts of Venice will be submerged by 2150.  The study was carried out by experts at the National Institute of Geophysics and Volcanology (INGV) and analysed data on tide level rise. 

Venice has been battling increasingly frequent flooding for decades.  There is now a system of flood barriers in place in its lagoon, a shallow, 550 km² enclosed bay in the northern Adriatic Sea that surrounds Venice and its islands. But these won’t be enough to protect the city from continual sinking and sea level rise.
