Ship Traffic Causing Venice To "Sink"?

Everyone has heard the phrase "Venice is Sinking", which is not true. From about 1900 until 1970, it was lowered about 5 inches into the water because of the drainage of the aquifer that Venice sits on. Once they stopped draining the aquifer, Venice rose about an inch. Global warming is ultimately the cause for the rising sea levels, which makes Venice susceptible to flooding



Another suspected cause for the raising of the sea level in the lagoon around this historic city is the dredging of inlets and navigation channels in the lagoon, and the subsequent increase of ship traffic.


If this is truly a cause for the rising sea level in the lagoon, it would be obvious that if you want Venice to stay around as long as possible, dredging of canals and excess ship traffic should be avoided.
