Coastal cities, towns and villages should have a reverse-osmosis system in stand by to be honest. i cannot understand this panic for water, same with Liguria past Summer....
What is causing reduced sea level in Puerto Pollensa, Mallorca?

So…while dog walking today another dog walker said, have you seen how low the sea is?..it’s all over the news !
Funnily enough I was out on the water this morning…and it looked fine to me…what do you think

You can see the problem right there - there isn't even enough water to make the pointy bits on top!So…while dog walking today another dog walker said, have you seen how low the sea is?..it’s all over the news !

Historically, they've relied heavily on run-off from the southern alps to fill the lakes in the Verdon valley (Sainte-Croix, Castillon, Esparron) and the Saint-Cassien during the spring months, and then slowly depleted them during the summer months when demand for water peaks because of tourism. There has been no need for reverse-osmosis/desalination plants.
Low annual rainfall, lack of snow and record temperatures over the last few years has brought into focus what I suspect will be an increasing challenge for them ... both practically and economically. Many of the ski resorts have really struggled with snow conditions over the last 2-3 years and water shortages impacting tourist areas in summer are becoming a very real issue. Last summer, in some areas they had to use tankers to bring in water to fill local reservoirs.
Some kind of long term solution is needed .... but I'm not holding my breath!

When I arrived back in my berth this morning it was about a foot down..not a problem…now it’s about two feet down..but I have seen it lower

You guys cannot all be wrong, yet Risk to World Heritage Sites across the Mediterranean from rising sea levels

ive now learnt locals call it ‘Calmadas’ …. Typically millpond calm in February with high pressure reduces water level, no one seems concerned. Weather about to change and I’m back to uk until end April so should be back to normal by then! Just to remind you why Mallorca is so great photo attached, looking back to Puerto Pollensa from Bonaire Marina with flat calm sea, enjoy!
Thanks for all responses

From Reuters Italy faces new drought alert as Venice canals run dry
A contrast to #26

started doing it in various smallish Aegean islands. It's funny, there are islands with 100 inhabitants off season and like 10k + during the 3summer months. No way to survive like that, no reservoirs, no springs. They used to have a water tanker going around but too cumbersome, so now slowly changing to desalination plants unfortunately often mated to massive diesel generators that "run" the island as well.

Maybe that's the problem, all those large super yachts leaving the Med has let the Med re-adjust their displacementPerhaps he has a very big boat.

The tides are several metres where I go to sea
They are affected by the weather as well as the moon.
Venice canals start to run dry as low tide and lack of rain hit

Is the water still low in Venice. Apart from the Reuters report, I have seen nothing more online. It is still a mystery,

It’s been very dry in the Alps this yr .Last real precipitation which falls as snow was 10-13 th Jan .Sunny every day since and very cold with a blocking high pressure.
The piste high up are currently 90 cm , previously yrs up to 4 M , ave nearer 3 m .So come spring when it melts there’s no volume to melt off , only a fraction of water stored as snow compared to previous yrs .
Anecdotally the river Po s tributary NW Torino is very dry .I mention this as they are building a new motorway bridge across .
Normally with the middle pillar in a river they uses caissons to keep the water away temporarily from the river bed .They haven’t bothered his time as the level is so small a few planks and shuttering , a big bucket or two and they have created a nice platform to build / sink foundations for the bridge pillars . The heavy plant is just running up / down on the river bed of rocks .
The Po runs out in the Venetian delta btw .
Theres nought coming in at it start .

Where does the water come from that becomes rain and snow?
Is the Mediterranean no longer connected to The Atlantic?
Isn't sea level rising due to global warming?

interesting to see the levels so low in Venice. I’m looking at renting a boat near Treviso to cruise around Venice and the Venetian Lagoon area. I wonder if this is affecting boating in the area.

The earths water content is constant Solid ice is decreasing.Liquid is rain and rivers/ lakes and sea .Atmospheric are clouds and humidity.
Its shifting more aggressively than ever between the three as global ave temps net increase .
Hard to exactly predict outcomes .
I have just reported the Alps “ ice “ inc snow is very low this winter and re Venice one of its it’s main tributaries to the Po is almost a trickle at the mo and there ain’t a lot of stored “ICE “ to refill it in April , May .

It's mere science. All the Russian superyachts moving to Turkey to avoid being impounded has raised the sea level there and as a result it's been sucked from Mallorca! The 'Mallorca Sucky Effect' !

So if there is less ice and less rain and the Earths water content is constant there must be more water in the sea.

Less ice .
Not exactly sure where it’s gone .Maybe more the water than previously estimated is airborne as clouds / humidity etc Anyhow it’s fractional always was .In terms of it’s too broad a brush to say one way or another .Different areas or the earth are effected differently .
eg more flooding from rainfall in some parts , desert formation in others , dry ness with fires and equally torrential rain .
I am not denying global sea level rise eg in the Pacific islands . Small land mass ratio to sea surface area .The Meds the other way round large land masses surrounding a smaller sea area in comparison.As a result it’s highly likely they are effected differently to global warming .
Meds an interesting one because as others have said there’s a lot of rivers feeding a relatively small area .In the winter most annual water is stored as snow ( ice ) and slowly trickled in by melt water in the spring , and this yr those deposits are low .Precipitation has been low too .
Remember last summer broke a few records heat wise throughout the UK + EU evaporating more water changing it to gas / clouds etc putting it in the air where it moves a long distance I guess ? Rhine became unnavigable. It didn’t flood due to ice cap degradation.
As the Earth net heats up more water will end up airborne and stay up there moving unpredictability around .It’s not dropping back in the Alps/ Southern Germany / NW Italy ( origin of the Po) .
