Build massive inland freshwater lakes in the worlds deserts to manage sea levels.

Maybe the lakes could be built like the Kalgoorlie superpit. By using massive earthmoving equipment much larger than any in operation. Kalgoorlie superpit times a billion?

Pros-
Ability to manage sea levels
Massive amounts of fresh water available for farming
Creation of jobs
Get the world economy going
Cooperation between countries
Massive harvesting of underground resources for stockpile

Cons-
Might drastically screw up the planets weather patterns
Destroy desert ecosystems around the world
Destroy archaeological sites
Financial cost

...Or instead you could cool the earth - here is a way: tie a long rope between Jupiter and Earth, just for a short while as Jupiter travels in the other direction so it drags the earth slightly away from the sun!

Get over it!

Fishfarmer: Build massive inland freshwater lakes in the worlds deserts to manage sea levels.

Yep. I could see the Greenies & the local Aboriginal peoples going for that, Ay. Stock it with endangered freshwater fish, great for the birds, etc. ;-)

Thank You for this discussion.

A simple Google search will bring up many websites
on this global problem. It appears that there
are many coastal cities around the world that
are having flooding problems because of sea level
rise. We're told that average sea levels have risen
and continue to rise and that this is measured via
satellite. The Mayor of New York City has designated
$19.5 billion for a multidecade plan to defend NYC
against rising seas and severe storms.

Experts tells us that with around 85 per cent of Australia's
population living in coastal areas - rising sea levels and
storm surges will have significant impacts on many of our
coastal towns and cities.

Apparently over the past 50 years there have been 25 National
Inquiries and Reports into coastal management.
They have all come to the same
conclusion - what we need is one set of clear,
national guidelines on coastal development and infrastructure.

We could also do with expert advice from Dutch experts who have
been dealing with the problem of water for hundreds of years.

Part of New York City's plan may involve the construction of
permanent levees, sand dunes, portable storm barriers and
other climate defences. We're told that visitors to lower
Manhattan may find a Dutch-style dike between them and the
harbour.

It's worth Googling this topic on the web.
Interesting reading.

I guess the problem of Global Warming is really a financial one. Just think of the money these people who have invested heavily in building Costal High Rises will lose when they eventually topple into the sea.

Given that the Sea has been at least 30 meters higher at some stages in Earths history. I can't see it not being that high again sometime. Just from natural causes anyway. Look up Monash Universities "Sahul Time."

I'm safe, I'm 88 meters above Sea Level anyway & I'll be dead a thousand years before it happens. ;-) You cannot beat nature, ever.

//Sea Level Rise Solution?//

Build houseboats and float above it all.

funny the beaches I have visited for 50 years have not changed except for erosion caused by storms etc. Another imagery problem will need an imagery solution. Maybe a carbon tax!

TL: Build houseboats and float above it all.

Whatever floats your boat. Boom boom. ;-)

Actually I have seen a great deal of change. Especially in North Queensland around Alva Beach. My father said when he was young they had to walk at least a mile over the sand dunes to get to the water. When I was young the beach was right in & they were afraid the hut were going to get washed away. Then a great sand bar appeared with a lagoon between the Beach & the Lifesaver tower. Now it's back to being just a long skinny sand bar which may or may not be there after the next wet season.

The Coast is changing all the time. Except on the Gold Coast where they keep pouring good money after good money in a never ending battle to beat nature. Stupid.

Googling sea level rise reveals that the sea level has been rising fairly consistently at 1.8 - 2.2 millimetres per year since the last ice age. There has been a bit of an increase over the past few years but nothing out of line within the parameters of natural fluctuation.

2.2mm X 10 years = 2.2 centimetres, less than 1 inch per decade in the imperial scale. (Global warming alarmist suggest it could be as much as 4mm per year).

Going on the current trends we can expect the sea to rise possibly a foot (22-25 centimetres)over the next hundred years.

Research on atolls shows the coral can grow at the same pace and some of the Pacific atolls are growing... increasing shore line to match the increase in sea level.

The climate alarmists tell us this is a bad news (in my view as bad as the Y2K threat); there is no doubt in my mind that the impact of population growth over the next hundred years will be far more devastating to humanity.

farmerfisher, there's two more problems with your idea:

Firstly, where would we get all the fresh water? Evaporation from those lakes means there'd be LESS water available for farming.
Secondly, the volume of lakes needed to manage sea levels is absolutely enormous. As an engineer I'm reluctant to declare any scheme impossible, but even with the technology of Star Trek we'd have trouble doing it! Reducing atmospheric CO2 levels would be easy by comparison.

Who is old enough to remember when Barrenjoey was last surrounded by water?
The sand connecting it to the mainland will be an early casualty.

This is a really interesting idea: giant fresh-water lakes in deserts. We could build the many more desalination plants that would be needed, pump salt water through them to extract the salt, and pipe the fresh water into the sands of deserts, all across Western Australia and South Australia and the Northern Territory, four or five million square kilometres of it - all suddenly productive.

Better still, we could use wind power to power the desalination plants and the pumping stations. And, as somebody wisely suggests, we could stock those giant lakes with fresh-water fish.

People may laugh, but it could work: brilliant ideas are usually mocked at first .......

What are you going to do with all the salt?

The evaporation rate is tremendous out there. I suppose that would mean more rain for someone, somewhere. Hmmm... water vapour in the air, reflects sunlight & would cool the Planet counteracting Global Warming. Hmmm... Might work. ;-)
