Just saw this report about the canals in Venice drying up due to drought and the problems that is causing for Venice's only means of transportation.

https://www.yahoo.com/news/never-ending-drought-e ... 31865.html

However, the lagoon that Venice is surrounded by and feeds its canals is open to the Adriatic Sea, which is open to the Mediterranean Sea, which is open to the Atlantic Ocean.

So much for all this sea rise BS that the glo-bull warmers have for years been claiming is happening, and is going to flood all the World's lowlands ?

I think the answer lies in it's flood gate design https://sites.google.com/site/engineeringvenice/

This is not because of flood control, which they only use when there are very high storm tides. You don't use flood control for low water levels, especially when there is a lot of commercial boat traffic in and out through those inlets. This is the opposite of flood control - water levels too low that the article claims is because of a drought.

I spent the first 40 years of my life with a shallow bay like the Vencie lagoon, only much larger. The Great South Bay of Long Island. Like Venice it has multiple inlets to the ocean. If you go to Google Earth, you can view how well the Venice lagoon is connected to the ocean, same as the Great South Bay.

So, if glo-bull warming is raising sea levels, how could a "drought" not only lower the canals fed by the lagoon, but also the ocean that has several large inlets to feed into that lagoon if the oceans are rising ?

This is easily explained by the indisputable fact that due to global warming the earth is spinning on a new tilted access. Some areas that were once rain forests or prone to plentiful water are now arid or desert and other areas that were dry are experiencing flooding and rainfall like never before.

CLIMATE CRISIS
FACT CHECK: Are Venice canals really going dry because of the drought?
Venice’s famous canals are suffering from a lack of water, but how unusual is this and does it really have anything to do with the drought hitting northern Italy?

Pictures of dried-up canals and traditional boats hopelessly stranded in the mud have featured in international news reports recently as Venice continues to experience one of the longest low-tide events in its recent history.

And, while focusing on how the low tide is affecting local transport and emergency services, some news reports suggest the drought that’s currently hitting the north of Italy is the main cause of the phenomenon.

Italy has experienced exceptionally dry weather over the past few weeks – the Alps have received less than half of their normal snowfall so far.

But is this why Venice’s canals are drying out?

While northern Italy’s drought might have reduced the amount of fresh water entering the lagoon via nearby rivers, experts say this has little to no bearing on Venice’s currently dried-up landscape.

“The drought has nothing to do with it,” because “rainfall doesn’t affect tide levels,” Georg Umgiesser, a marine researcher at Italy’s National Research Council (CNR), told weather website MeteoWeb on Tuesday.

As with all tidal events across the world, Venice’s famous tides are influenced by four main factors: astronomical events (i.e., the Earth’s rotation and the gravitational effects of the sun and the moon), winds and their directions, sea currents and atmospheric pressure.

A “combination of meteorological and astronomical events” is exactly what’s behind Venice’s dry canals, Umgiesser said.


In particular, a spell of high pressure over the Adriatic, along with the new moon phase and the moon being at its nearest possible distance to the Earth on February 18th, all contributed to the city’s low tide, or bassa marea.

So it would be factually wrong to state that northern Italy’s dry weather is at the root of the low tide.

And low tides, which are defined as the city’s water level being 50 or more centimetres below the zero tide gauge (-60, -70, etc.), are far from an anomaly in the (formerly) floating city.

In fact, although they’ve become significantly less frequent over the past two decades due to rising sea levels, Venice still sees one to ten low tides every year, with most events taking place between early January and late March.

Unlike ordinary low tides though, the current event has been going on for days on end now. According to Alvise Papa, who leads Venice’s tide centre (Centro Maree), “it’s the longest stint of low tide in 15 years”.

" Venice’s latest bassa marea could hardly be described as historic. The city has seen 160 low tides with levels equal to or lower than -90cm since 1872, whereas the current tide has ‘only’ reached the -70cm mark so far."

Bingo!

So, it is not caused by drought, and the claimed "glo-bull warming sea rise" is not enough to prevent canals going dry, much less cause flooding of sea level coastal areas.

In other words, the reports meant to make to keep us in a panic are wrong,.... again. But then, the environ-mental alarmists have not been right in their predictions of doom even once in 60+ years.
