Scientists Reveal 4 Stark Options For Saving Venice From Rising Seas
ScienceAlert • • world
Key Points:
- Venice faces the risk of being lost to rising sea levels within the next three centuries, driven by climate change and the sinking land beneath the city.
- Scientists evaluated four protection options: movable barriers, ring dikes, closing the lagoon, and relocating the city, each with varying costs, benefits, and impacts on Venice's cultural and ecological heritage.
- The current strategy of using movable barriers is becoming ineffective as sea levels rise, with projections indicating it will fail by 2300 even under low-emission scenarios.
- Ring dikes and permanently closing the lagoon could offer more robust protection but come with high costs and significant ecological and cultural trade-offs, including potential loss of Venice’s port function and lagoon ecosystem.
- The most drastic option—relocating Venice’s residents and monuments—would be the costliest and most disruptive, highlighting the urgent need for policymakers to begin planning large-scale interventions soon.
