On 14 May this year, Italian Prime Minister Silvio Berlusconi cut the ribbon on a multi‐billion‐dollar project named MOSE that is aimed at solving the problem of “acqua alta,” the increasingly frequent floods that jeopardize the survival of Venice. Cost is estimated (a few say conservatively) at 3 billion euros and construction time (a few say optimistically) at 8 years. MOSE involves building mobile barriers at the Venice Lagoon inlets to prevent severe Adriatic Sea storms from flooding the city. Although the Italian government and the local administrations have given their final approval, MOSE still has several opponents who believe it will cause severe threats to the lagoon ecosystem, and will soon become obsolete because of the expected sea level rise due to global warming.
