Venice Faces High Costs After High Tides Sabina Castelfranco ROME - Venice has been feeling the effects of global warming, with more frequent events of high tides and rising water levels in recent months. On Nov. 12, the lagoon city suffered a particularly severe event that caused significant damage to its buildings, churches and cultural heritage. Now the water levels have receded and tourists during this carnival month are again able to enjoy the city without having to wear rubber waders.But for the authorities, the clean-up operation following the high tides is a work in progress. Rising waters during the winter months are nothing new for Venetians, who have lived with high and low tides for centuries. .
