Venice Faces Drowning: Climate Change Threatens City's Future

Research published in Scientific Reports warns that Venice will "ultimately be lost" without rapid intervention to combat climate-driven flooding. The historic Italian city serves as a critical case study for adapting to climate change consequences.

Scientists compared four adaptation strategies, finding no single optimal solution. Each approach preserves certain aspects of Venice—like its urban fabric, ecosystem, economy, or safety—while compromising others. Projections show sea levels could rise between 0.42 to 1.8 meters by 2100, potentially rendering Venice's current mobile flood barriers inadequate if the rise exceeds 0.5 meters.

Additional measures, such as raising the city and lagoon or implementing dikes and closed-lagoon strategies, may be necessary. However, these interventions could significantly impact Venice's role as a port. The researchers stress that planning must begin immediately, as large-scale defenses can take 30 to 50 years to construct, emphasizing that "infrastructure designed for the past climate is increasingly misaligned with present and future risks."

Venice has experienced 28 extreme flooding events affecting 60% of the city in the past 150 years, with 18 occurring this century. The Mediterranean is becoming a climate change "hotspot," with high water events happening more frequently and with greater force outside traditional seasons. Without swift emissions reductions and urgent adaptation, the scale of these impacts may surpass management capacities.
