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.
