It is hard to believe that Italy’s “floating city” could be underwater soon.
Predictions for the future of the city vary, but most scientists agree that the sea level is rising due to climate change. Natural Hazards and Earth System Sciences, an interdisciplinarity journal of the European Geosciences Union, published a report in 2021 suggesting the average sea level could be between 17 cm and 120 cm higher in Venice by 2100.
Venice was built in the middle of a shallow lagoon in the Adriatic Sea. Therefore, it has always been at risk of flooding or “acqua alta,” meaning high water. There is evidence of severe flooding dating back to around the 8th century.
The Venetian lagoon is more than 500 km2 in total, but has an average depth of only 1 m, according to Royal Museums-Greenwich. High tides and severe storms have a devastating impact on the wetland environment on which Venice is built.
In November 2019, Venice experienced the second-worst flooding event in almost 100 years. The tide reached 187 cm (6.1 ft) above sea level, covering 80% of the city in water, reported the BBC.
City records show there have been 324 intense high-water events since 1872 and more than half of those have been in the past 30 years. Among the many and vast consequences of human-caused climate change may be the end of one of the world’s most beautiful cities.
Only time will tell the fate of Venice.
